Title: Meister A6M3 Model 22 Zeke Build
Post by: Lane C. on September 02, 2017, 09:22:30 am
Hot on the heels of the CARF P-51D comes the Meister Zero build. I've had the kit for 2.5 years and finally decided to make it a flying model. Done a bit on it yesterday with the glass fuselage. Going to mount the engine and setup the fuselage first, then build the wing and tail. I will run a DA-100 twin-cylinder and use Sierra retracts. Hope to have it ready next year. We'll see how that goes.

I have a laser cut kit for the fuselage formers, wing, tails, spinner, canopy, plans, and cowl as part of the kit. Plus all wood for sheeting the wing and tail surfaces.

The version will be a Model 52 A6M5 Zero with 108 inch span. Can be built as a Model 21 with 118 inch span as well. But I like the later versions. All Zeros were Japanese Navy birds. Some assume they were split between Navy and Army, but they were always under control of the Navy. After Midway, the Navy was kinda short on Carriers, so, they became land-based and were painted green.

I may re-use Saburo Sakai's A6M5 Model 52 as a color scheme. I used this for the basis of my CMP Zero. Sakai was the highest ranking Japanese pilot that survived the war. He claimed 64 kills as I recall. Two other higher ranking pilots were killed before the war ended. Saburo lived until 2000.

Got the plans out to measure where the formers go.

Fuselage is on two sections. Makes it easier to do the initial work.

Hey, how can you start another build when you haven't even flown your P-51?

You need at least two or three hundred flights on the P-51 to get it broken in.

Steve! This is CRABTREE AIRMOTIVE! Did you forget that? We do many things at once. It's called mulit-tasking. Actually, just needed something to do. ha

Got a few more things done on the Zeke today. Got another former B3 fitted with the sub former. This supports the wing hold down system with a cross brace of 1 inch square basswood from formers B3 to B4.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9451_zpsakmp6za6.jpg)

Smoothed out the rough cut edge of the fuselage front and got the firewall fitted.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9466_zpsmo6cadqr.jpg)

Next, trimmed the other 1/4 inch firewall half and epoxied on bottom of the front piece. Only used 28 clamps. Next I will epoxy and glass the firewall in place. I might even use 2-part Hysol! Only thing with Hysol is it takes 12 to 24 hours to setup firm; two or three days to really get hard. You cannot move it until it's dried 12 hours unless you have it screwed in place.

Got the firewall clear of clamps and sanded the edges free of epoxy. Temporarily screwed it to the fuselage so i can fit the engine when it comes in. I'll need to build an engine box to slide fore/aft to fit the cowl.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9470_zps9kzx9yjs.jpg)

Plenty of room around the firewall for Hysol and then some glass tape and Z-Poxy to really secure it. I won't glue it in until I decide where to have the engine box so I can cut the square opening in the firewall on the work table.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9472_zpspajjfuka.jpg)

Zero spinner. Note the flange on the backing plate. The spinner is actually inside the cowl a small distance.

Got the Dremel tool out and opened things up. First did the Cowl.


(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9476_zps95miezeh.jpg)

Spinner pretty well fills the opening.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9480_zpsgbpdmseh.jpg)

Then the cockpit area.

Had to make a bulkhead/former that Meister didn't furnish. But, it was listed on the plans. I traced it out and made my own bulkhead since I need it to hang the servos on the aft side and support the gas tank on the fore side.

It's almost all the way forward and just in front of the instrument panel. Not sure why Dino didn't include this former as you need something there to work from. Oh well, it's there now. I still need to make a pass thru hole or holes in this former and figure out how I am going to support the servos and gas tank. The servos need to be as far forward as possible to keep weight off the tail end. The Zero has a short nose and one extra ounce in the tail requires 10 ounces in the nose to balance out. It adds up quick. I'm still doing some layout lines and a few things before I glue the formers in place. Once they are glued in, it's really hard to cut holes and get support wood to be square and level.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9495_zpsfeb711r5.jpg)

Here's the overall view of all the fuselage formers, not including the firewall.

You are a builder extrodinaire. I will be watching. Is that big wing a 1 or 2 piece for transport? Saturday Big Bird wx is looking good. Hope you can make it over.

Hi Darrell, thanks, but I'm not that great a builder. You, Jack Haynes, Max Ficken, Lee Rice, Ed Couch, are great builders. Going to be a 2 piece wing. Planning on bringing the CARF P-51D out for viewing on Sat. I'd like to bring the P-47 to fly, but want to show the P-51. Cannot haul them both!

Back to work. Received the DA-100 on Friday. First thing to mount the engine is to determine centering and how much spinner clears the cowl.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9565_zps4xceqdcs.jpg)

Looks good.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9573_zpsnxufbfmf.jpg)

Better view.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9580_zpstyciuhq0.jpg)

X marks the spot. The firewall needs cutting on the outlined spot.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9583_zpsdxip4z9x.jpg)

Made the engine box. It will fit thru the hole in the firewall and be adjustable in height or forward and aft, depending on your viewpoint.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9585_zpsey7bwoeo.jpg)

Engine sitting on the box.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9587_zpsle30k1va.jpg)

With spinner. Once the box hole is cut in the firewall, I can tack the engine box in place with some servo screws and fine tune the engine mounting.

Cut out the firewall for the engine box to slide thru. Got the engine box opened up for access to the fuel tank and fuel lines.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9604_zps7zpxat9j.jpg)

Lots of room for fuel lines. I use a 3 line tank system - fuel in, vent, fuel pickup to engine.

Do you have some down and right thrust in there? Is that denoted on plans?

Looking good, Lane!

I noticed you had removed the Zeke from sale on RCSB.  I will be watching with interest.
Title: Re: Meister Zeke Build
Post by: Lane C. on September 20, 2017, 05:11:38 pm
Yo Darrell, Just by accident there is some right and down thrust. For some reason, the engine box front plate was out of square in those two directions. That's what Bob Ross the TV oil painter calls, "A Happy Accident."

Yo Tim, I always said if I didn't get what I had in it, I was going to build it. So, that's how it went. Zeros just fly too dang good!

I got the other side cowl flaps cut out and glassed in place. Next, I had my neighbor who has a machine shop cut down some stand offs to 1-5/8 inches for the cowl ring mounts. Then I tapped the holes for 10-32 threads.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9664_zps8pgrcb4n.jpg)

The cowl ring needs to be bolted to the stand offs, but at a very specific place. This is a blind mounting situation where I cannot determine where the hole should be without fitting the cowl over the ring first on the fuselage. To find the hole, I made a jig that fits over the stand off on one side of the cowl ring and slides over the top of the cowl ring to show me where the hole should be. I then drew a circle inside the hole and the dead center of that is where I drill the new hole.

Jig made from two pieces of balsa and a brass tube to drill the hole. A 1/4" block was placed between the two pieces and CA'd.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9663_zps40udynkw.jpg)

Another view of the jig over the stand off.

And another view showing the pencil mark.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9646_zpsyiq0fywo.jpg)

View of the cowl ring in the position it will reside. I had to offset the ring to allow the cowl flaps to be open to allow exit air from the DA-100.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9656_zpsrrqtx8ch.jpg)

After I knew where the holes were, I removed most of the plywood to leave just enough to hold the cowl in position. I will add some more plywood on the front side of the ring to hold some 6-32 machine screws. Probably at least 6 screws.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9667_zpsetf1cmpt.jpg)

Now, there is ample room for the hot air to pass thru the ring and out the cowl.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9668_zpsa1r43csq.jpg)

Semi-done view of the cowl with flaps open from the bottom side. I still need to do some work on exactly how the cowl should sit before screwing it down.

Post by: Lane C. on September 20, 2017, 05:20:19 pm
This post is out of sequence, but I should show how I opened the cowl flaps for the exit air. The cowl fit on the fuselage dead tight, so there was no way to properly cool the DA-100. The outlines for the flaps are in the glasswork, so it's just a matter of carefully following them with a Zona saw.

After cutting them out one by one, I glued them back in position at a 20 degree open angle with CA. After getting all of one side done, I had to glass them on with Z-Poxy and 2 inch tape before moving to the other side - very fragile with just CA holding them in place.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9642_zpsncti9fmb.jpg)

Another view. And that takes us back to the above post where both sides have been done.

Moved the box up only 3/8 inch and notched the corners for muffler clearance. Wanted the spinner a bit closer to the air intake cross bar.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9679_zpslzkfqikk.jpg)

Mufflers in place.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9681_zps8twxlkme.jpg)

I laminated two 1/4 inch plywood pieces and then glued it in the void area.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9685_zps39ail8wf.jpg)

Tight fit. I still need to pin the corner joints on the engine box with a few bamboo dowels welding rod sections to add the last bit of shear strength to the box. Already used tri-stock inside.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9686_zpsrunhwg7n.jpg)

I bolted the engine to the box with 1/4-20 bolts and Tee-Nuts. The engine box is still free to move, but in there very tight after refitting. I can set the fuselage horizontal since the engine is bolted in.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9691_zpsgabizqc7.jpg)

Also installed the mufflers and cut the cowl for them to poke thru. Not sure how they will fit thru the cowl while installing it with the front baffles installed. May have to slot the openings lengthwise (forward/aft). I can cut them just a tad shorter if I have to.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9687_zpskiatayar.jpg)

Side view.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9695_zpssqqrg9fx.jpg)

Moving the engine box up got the spinner closer to the cross bar of the intake.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9697_zpszswrpqoq.jpg)

Little bit better view inside the cowl flaps.

Worked the Zero all day long.

Got the firewall hysol'd in place.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9707_zpslnuiwcbj.jpg)

Glued in the engine box and tri-stock.  Then gave it a coat of Z-Poxy.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9704_zps2eqkne6n.jpg)

Added the cowl ring.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9721_zpsbt15e6p5.jpg)

Bolted in the engine.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9709_zps7wztpj2x.jpg)

Added cowl. Cut the spinner for the prop and hung it on the engine.

Got some more things done today. But mainly, tried the spark plug caps with the cowl and they were too tight up against the cowl. Just couldn't get the cowl on. Had to do a slight relief cut on each side. Spinner was drilled and tapped for 8-32 screws. Cowl is now held on with 4-40 screws and Tee-Nuts. It's on there very solid.

I ordered a cockpit kit from Dino at Meister Scale. Came in yesterday. Bigger than I thought it would be. Now, I can determine how deep the cockpit it and setup the servos underneath. I will use a pull pull servo for the rudder and tailwheel and not sure on the elevators yet, might place the servos in the tail.

Back on the Zero project. Glued the back half of the fuselage on with Hysol.

Cleaned up the gluing joint with 60 grit and Acetone.

Got the rudder done today. Needs to be fitted it to the vertical tail, but I have to make and install the horizontal tail first. Otherwise, won't be able to see to fit and glue the tail. The horizontal tail is built solid, both halves, and installed THRU the fuselage cutouts. This is not going to be like an ARF where you have aluminum spars that go in the tail, thru the fuselage, and over to the opposite side. Should be solid however. Ordered a Robart large 160 pneumatic retract tailwheel from Tower, so, I can get to that and the rudder after I build and install the horizontal tail.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9893_zps7th1egpb.jpg)

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9895_zpskbgolxus.jpg)

Made a sanding jig for the radius on the front of the rudder. Pretty handy to have. These can be made to any radius you need and only takes about 15 or 20 minutes to make. I used some scrap plywood and 60 grit paper tack-glued in with CA. Paper usually lasts a very long time before it needs changing as it is just used to sand balsa.

Had to do the final work on the interior of the rudder. I shed 0.56 ounce by doing this. On the tail end, every little bit of weight removed helps.

Looking good. You probably spent more time on that rudder than I did building my entire plane.

It seems like every plane we have wants to be tail heavy since our engines are getting lighter. My rule of thumb is an ounce on the tail = three on the nose. Our batteries are also much lighter so they don't help much to counter excess tail weight.

All part of the joys of building.

Post by: Lane C. on November 12, 2017, 10:23:59 am
Hey Steve, I spent more time LOOKING at the plans and parts than building. This is my first Meister Scale plane and it's a bit different than most kits as the instructions are minimal and the building style is new to me.

I rely on good old fashioned LEAD in the nose to make up for poor building techniques. Last two Zeros used FOUR POUNDS of it right over the engines.
Title: Re: Meister Zeke Build
Post by: Lane C. on November 14, 2017, 06:23:14 pm
Got on with the build, moving to the H tail.

Made the trailing edge first. Meister shows to build the tail vertical.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9907_zpsmear2lod.jpg)

Started laying in the ribs. On each side, the inner and outer ribs are placed first, then the top cap, then the rest of the ribs. A metal rule helps to keep the ribs in alignment.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9914_zpsaxcozpfr.jpg)

All the ribs in place with center piece joining the two halves.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9918_zpsza8fk2vd.jpg)

The trailing edge and top cap strip were too wide for the ribs and needed some extensive sanding to make them match. This needed to be done for the sheeting to lay down properly.

The tail is put on stand offs to keep it true to get ready to lay the sheeting.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9924_zpselcv79zd.jpg)

I made one of the 4 sheets and put it on the tail. Sprayed it with Windex to help it to conform to the contour. Needs to dry overnight before gluing on.

I redid the supports on the corners and middle of the wing to keep the wing straight for sheeting.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9926_zpsn0lr5sfo.jpg)

Got one sheet on with yellow carpenter's glue. Pinned down as many places as needed. Clamps too. I hit the sheeting with a bit of windex to relax the balsa.  Hope it all goes well.

I saw some good glue "squish-out" on the edges of the sheeting so I feel there will be  good adhesion. Wood glue is old school though, takes a couple of hours to setup. CA spoils me.

I can't believe you're using the old yellow glue.

For my coroplast plane I bought an 8 oz bottle of slow cure CA. The cost is really cheap that way. I use the little plastic squeeze tubes to suck the glue from the big bottle and use them to put the glue where I want it, they are long and skinny so they work great.

The bipe took almost 5 oz of glue.
Title: Re: Meister Zeke Build
Post by: Lane C. on November 17, 2017, 11:46:02 am
Hi Steve, the reason I used yellow wood glue is it gives me time to position the sheeting. Even thick CA will setup too fast for me. I'm a slow poke. Plus, the wood glue penetrates the balsa very well. So far, it's worked out well. And Meister's builder said he uses wood glue on his sheeting for Dino's planes. Down side is it takes several hours to dry. But, for the rest of building, I use CA.

After lots of sheeting work, and a bit of warping I had to overcome, I got the tail sheeted and sanded. Still need the wing tips and elevators. Been working all this week on this. Seems like a long time to spend on just one small tail.

Took the plunge and routed out the fuselage ports for the horizontal tail. First cut was a rough cut. Then went to the 5/8" Dremel drum sander. Had to go past the rear of the first cut another 3/4 inch. But, the tail fit without too much trouble.

As usual for Crabtree Airmotive, an excellent build blog in progress. You really ought to send this one to MAN once your finished. I bet they would (should) publish it in a heartbeat.

Also, if there's room to shoe horn in another zero in the paint booth (when that time comes) let me know, there's a paint needy Zeke in Bedford. Ha!

Thanks guys.

Sonny, I have another long article sent to MAN's Debra Cleghorn on painting the P-51. But, she loads them in every so often. Not sure when she will get to that one. Online only, of course - my photos are not the Madison Ave type, just everyday real world pics. Not the kind you see in the magazines.

As far as painting, looks like the painting season is pretty much over for 2017. Guess the paint shop will re-open next Spring. But, not planning on any TWO MONTH paint jobs like the P-51! The next paint scheme will be as simple as possible.

Got the right side elevator done today. There's not too much more to do on the horizontal tail now except to glass it. I can't mount in in the fuselage until I know what the incidence is and I need the wing on to do that. So, maybe it's time to start the wing build. Or, continue on the fuselage by mounting the elevator and rudder servos. Plus, the cockpit kit needs assembling, canopy, etc.

Title: Re: Meister Zeke Build
Post by: dlabby on November 22, 2017, 10:06:29 am
3 deg positive incidence on the horizontal stab? So it is a lifting tail; was the real plane like that? Fuse build is looking great.
Title: Re: Meister Zeke Build
Post by: Lane C. on November 22, 2017, 11:42:20 am
Hi Darrell, I put that note there to remind me of what I heard from the builder of another Meister Zero. He reported that you need +3 degrees incidence to keep the nose from climbing under full power. The plans show +2 degrees. I think some engine down thrust would counter some of the extreme climb out on full power. Of course, flying full power is a must! Especially flying wing with Barry's Zero!

I moved on to the cockpit setup. Seems the kit is larger than I expected and is taking room away from the servo mountings. May have to cut the cockpit down a bit to fit then underneath the floor. "Bill" is a 1/4 scale  Aces of Iron Pilot I've had for 10 years. Never finished his paint job. I feel he needs a new name like Saburo Sakai.
Title: Re: Meister Zeke Build
Post by: dlabby on November 25, 2017, 05:38:48 pm
I have been looking at 1/4 scale pilots and they are 15" tall which would make the real guy 5' (60"). That seems right but I don't see how that size will fit in the 1/4 Cub. Is Sakai 15"?? He looks kinda big, too.
Title: Re: Meister Zeke Build

You just need to add a couple of inches to his legs then he'll be perfect.
Title: Re: Meister Zeke Build
Post by: Lane C. on November 25, 2017, 08:23:42 pm
I'm likely to buy a Best Pilots Saburo Sakai full figure. He's 1/5 scale so that should work out pretty close as the Japanese aren't giant people.

Got the "B2" former glued in today. the servos will run parallel to the former for the rudder and elevator. Still room to access the gas tank and whatever else I need to cram in there.

Thanks Darrell. My ideas usually work out, but sometimes maybe not. Hope this one on the servos DOES work out.

Got the third former in today. Will glass it next.

Also, I have the Horz Tail rough fitted. And with that, got the tail cone pretty close to a final fit. But, lots to do next. I need to glass the tail and get it Hysol'd in place. Then work the tail wheel setup and add the rudder. Once I do that, I can get the servos installed and add some pushrod linkages.

Since I have the tailwheel on hand I wanted to see how it's going to fit. All this is just a temp setup, nothing glued. I am going to remake that oval former as it's a light plywood piece and it's flaking apart. Not good. Had to do some cutting on the tailcone to allow the tailwheel to drop thru. Still need a tailwheel.

Keeping on the horz tail by making mounting hatches for the elevator servos. Involved cutting two openings in the tail and making a 1/8" plywood hatch for each. The servos are secured to the hatch in a conventional manner with hard mounting blocks epoxied in place. Mounting the elevator servos in the tail like this avoids a traffic jam in the tail cone area where the rudder and tailwheel controls reside.

Set up the fuselage in reverse to see how +2 degrees horz tail incidence looks as the bird is flying. It will look pretty close to this.

Tail end blocked up to make the tail incidence read ZERO on the meter.

Still pluggin' away. Started today on making an external pushrod for the rudder vs all internal. I think it will work fine.

Had to cut a slot in the vertical stab to exit the pushrod.

Post by: Lane C. on December 26, 2017, 09:41:46 am
Got the tail epoxied in place.

First pic, I used 3/4" triangle stock to hold the tail in place against the fuselage sides.

Next is an interior shot of the tri-stock with pins holding them in place. This holds the tail in place and fills that rather large gap so I can build some new fillets.

Next. The tail is now permanently in place at +3 degrees incidence.

Next. Radius gages were used to make the new fillets.

Next. First pass on the new fillets. 30 minute Epoxy with micro-baloons used for the fill. It will take another pass to bring the fillet where it needs to be.

Next. A shot of the upper side of the tail showing balsa dowels to hold the tail in place. Some glass tape and West Systems Epoxy on top will really lock it in.

So, with the elevators getting dual servos, rudder getting an outside pushrod, that leaves the tailwheel steering the only thing inside the tail cone to mess with. Cleans things up nicely.

Title: Re: Meister Zeke Build
Post by: Lane C. on December 26, 2017, 07:45:26 pm

Post by: Lane C. on December 27, 2017, 10:11:49 pm
Got some glass tape on the inside of the tail. Used West Systems Epoxy thinned with denatured alcohol. Sopped the tape with epoxy on a plastic bag I sliced open and then laid it in there. Seems to have done the job.

Got the gap on the opposite underside filled with epoxy. Got this side a bit more filled where I can sand it down even with the fuselage. The first side needs more epoxy to completely fill the void.

Got to have a secret door to hide all the power switches. Well, not so secret, but keeps the side of the fuselage looking clean.

Laid out and cut a hole in the left fuselage behind the cockpit.

Glued some small formers in to support the plywood switch-mounting board.

No pics, but added the Futaba 3305 metal gear servos for the rudder and tailwheel steering. Hooked the pull-pull steering up and it works fine. Now, waiting on two Hitec 7245 metal gear mini servos for the elevators and some Solar Tex (translucent) white to cover the rudder and elevators. Then, I can glue all 3 surfaces on. After that, need to do final fitting on the tail cone and the aft end will be pretty much done.

Having more fun on Sunday than is legal! Took care of some loose ends on the tail cone. The cone didn't match up to the elevators, so I took care of that with some G10. Now, the tail cone looks correct.

First photo shows the misalignment that was present. The G10 is inserted into the tail cone curve to make the curve meet the elevators. It was CA'd in place and filled with some Dolphin Glaze filler.

Last photos shows how it is supposed to look.

I keep forgetting to order a set of the Robart composite sanding drums for the Dremel tool. Those paper sanding drums are nice, but too much heat causes them to explode off the drum.

60 or 80 grit paper on 12 inch by 2 inch balsa stock is one of the best RC building tools ever. Ed Couch got me onto that one 30 years ago.

Haha, yes Darrell, I bought some knock-off Dremel sanding drums and when they get hot, they just come undone and at high RPM, they seem to explode. For that balsa sander with 60 or 80 grit, get a piece of balsa at least 3/4 inch thick and 12 inches long by 2 inches wide. Use 3M contact cement spray on both the balsa and the sandpaper, let it dry 15 minutes, then press the paper in place on the balsa. Works fine, won't bind, lasts a long time, won't rust, bust, or gather dust. As seen on TV!

Also got some heavy servo extensions from Electro-Dynamics today, hooked up the elevator servos, and ran the extensions up front.

But wait, there's MORE. Got the rudder glued on yesterday. Been wanting to do this and finally got her hinged. After the epoxy had dried, I tested with the rudder servo to make sure all was working freely. Seems good to go. Also, sprayed the rudder and vertical stab with a coat of primer. Lots of pin holes in the glass tail to fill. Pretty much finished the bottom fillets. They take lots of time to form and I am tired of messing with them! ha. I laid some masking tape down on the top lengthwise joining seam so I could hit it with some primer to see how well I had sanded the joint. Still had some pin holes in the glass so I laid down some Bondo Spot putty and then sanded that down. One more spray of primer and it looks good. Some very minor pin holes left to fill. The bigger task is making that mid-fuselage joint look good. This is where I joined the fore and aft sections with Hysol. The two pieces made a successful joint, but they are off a bit and need some Bondo work to make them smooth.  Couple of more joints on the fuselage to make look nice, required, but very time consuming.

I've been watching the Breaking Bad Marathon 10 Year Aniversary on each Sat/Sun in January. So, didn't get much done this weekend. But, Friday I got some more work done on filling the gaps on the mid-fuselage joint. Used more Dolphin Glaze putty. Goes on easy and sands easy too. This is not really building in my book, but it needs doing. All just part of the game. Things like smoothing this joint are what make ARF's so popular.

I borrowed some dolphin glaze from Barry one time (I think it was on the P-51). I found it hard to work with; can't remember exactly why. You keep talking about it and I'm wandering what I was doing wrong.
Title: Re: Meister Zeke Build
Post by: Lane C. on January 22, 2018, 01:49:15 pm
Darrell, you likely put too much activator in the mix. It only takes a BB sized dot for the usual batch. It's meant for smaller areas so, you may have taken too long to get it laid down before it fired off? Also, to make it sand easily, let it dry for a few hours. It can be worked a short while after it has fired off, but that's just to get it rough-worked to shape with 60 grit, but you run the risk of pulling it off the surface if you try that too soon. Also, if you are working something that can be wet-sanded with 320 grit, it works very nicely, better than dry sanding. It's one of those things that takes a bit of using to get the feel. But, by-and-large, it works well for me. Lee Rice gave me the heads up on this putty. He hasn't steered me wrong yet! ha
Title: Re: Meister Zeke Build
Post by: Lane C. on January 22, 2018, 05:47:39 pm
Darrell, here's the sanding block. Works great with 60 or 80 grit. If your Dolphin Glaze is dried hard, it should produce fine sanding dust like this using 60 grit.

On the mid-fuselage joint, finally got it whipped into shape. That is one thing you won't find on an ARF!

Title: Re: Meister Zeke Build
Post by: dlabby on January 22, 2018, 07:26:37 pm
Boy, that fuse looks great after priming. I dare say you are right about too much activator. I think I remember it being very hard after curing. I probably used fine paper and should have used 60 or 80. I will have to try it again sometime. Stuff like that just takes some trying and trying and finally figure it out. I'm fnally home after 8 day HOU trip. Whew. I PM'd Sonny about the photo/text business.

Steve, I'll be thinking that one over while I put together the cockpit kit. Ha.

While working the cockpit kit, I found out the pushrod for the rudder was in the way of the floor and seat. So, pulled the rudder and tailwheel steering servos out and moved them to behind the cockpit area. And, changed out the rudder to a pull-pull system. Just not enough room to make a support for the rudder pushrod. I think it will work better with a pull-pull system anyway. Should have done that first time. Also, this gives me a bit more room up front to get to the batteries and gas tank. Had to add a control horn to the left side of the rudder. And, I'm keeping a mental count of the 2 pound diver's weights that will go on the front end with every little thing that goes AFT of the CG! I figure 6 pounds lead so far. Ha.

Retro fit/re-do isn't much fun.  :'( It feels like no forward progress...at least to me. On a plane this big, I think your pull-pull rudder is better-good change.

Darrell, I started to mount the servos back there, but thought better of aft CG and lead ballast in the nose. Oh well, she's gonna be pushing 50 pounds no matter what. Heavy planes penetrate better! Ha

I am shutting down the Zeke build for a short time to build a FW-190A by Top RC Models. So, it will be quiet here for a while. But, I can start a new build thread for the FW-190A!

The Zeke is inside the back bedroom for safe keeping during the new build. She's the "Hell Bitch" as Barry has named her. Will be over 7 feet long with spinner. Makes the P-47 look wimpy. Absence makes the heart grow fonder, so I will pine-away to get back to her while I work on another Axis hot rod.

Back on the Zeke build today. I had a problem with the spar material being too thick in the Meister kit, so had to do some repairs on the ribs. Got those fixed, so now I can get back to the build. Will probably wait till I fly the Porter to make full use of the build table though. The Porter kinda hogs the table. Ha

Added photos. I cut one-half set of ribs in the middle for the larger spar wood as supplied with the kit. I  tried to make it work out and then realized it was not going to work. I then put the spar wood thru the table saw and reduced the thickness. That was back in January. Now, with the ribs back to original configuration, I can proceed. I hope the wing half goes better this time than last time. Thankfully, I had not glued anything last time.
Title: Re: Meister Zeke Build
Post by: Lane C. on October 08, 2018, 07:31:26 am
Got the wing laid out once again and now there is another problem. I have to cut some of the ribs AGAIN to allow for the inner spar. Haha. Sort of ironic as I just patched the cuts I made last time and now I have to make similar cuts again! This wing is tough.

You can see how the inside ribs are not down on the sheeting. I'll need to cut a small notch out of them to clear the inner spar wood.

Last shot is the wing arrangement with wing joiner spar in place. Rather than use aluminum tube, Meister uses yellow pine with the diagonal dihedral cut.

I've left all the parts unglued as I am still figuring out the wing plan and how she's supposed to go together. For some reason the Meister plans are strange to me. If I ever get the left wing built, then the right one should be easy.
Title: Re: Meister Zeke Build
Post by: dlabby on October 08, 2018, 09:22:40 am
A laid out wooden rib wing is a beautiful sight. Yes I see your notch problem. But fixable; just take longer than it should. Building takes lot of patience. Your work just seems so much 'neater' than mine.

Post by: Lane C. on October 08, 2018, 11:49:50 am
Thanks for the comments, Darrell. I don't know, sometimes I feel like it's neat work and sometimes not. This left wing is coming along like the left wing on the Porter - pure Hell! Some of it's my fault, some Meister's. If I can push on thru this wing half, I will be on easy street with the other half. But as of this morning, still fitting, not gluing. Ha
Title: Re: Meister Zeke Build
Post by: Lane C. on October 10, 2018, 06:03:14 pm
I got things worked out and have glued up the ribs and some spars. It's proceeding slowly. Got a few pics of the progress.

Also, glued in the shear webbing on the aft side of the main spar. Forward side of spar has to wait until the bottom is sheeted to get the shear webbing.
Title: Re: Meister Zeke Build
Post by: Lane C. on October 11, 2018, 07:50:15 pm
Bit more done on the wing today. Added some balsa leading and trailing edges around the aileron and cut the pre-leading edge from 1/8" balsa sheet. This goes on before the 1 inch thick leading edge which is sanded to shape. The pre-leading edge is behind the yellow level to keep it straight. It glues against the very front of the ribs. The kit I just built, the Porter, simply blows the Meister kit away. Hard to believe the Chinese can deliver such a nice well engineered kit you can assemble WITHOUT ANY PLANS! And the Meister is hard to build even WITH PLANS!

Post by: Lane C. on October 13, 2018, 07:10:15 pm
I pulled the wing off the plans today. Looks pretty good. Glad to have gotten this far. Quite an improvement from last January. Needs a bit more work, but it is strong enough to move around off the plans. I think I will build the right half before I go on with the left so I can look at what I did for the left wing before sheeting over it.

Last photo shows some building aids I found at the local salvage shop on Hiway 199. The owner buys all his stuff from Lockheed Martin. All steel and heavy. $5 each piece. The 90 degree steel blocks make good rib holders while doing a glue up and weigh 2.5 pounds each. The black steel chunks just make good weights for whatever use and weigh 8.5 pounds each. Their flat bottoms and 90 degree sides make for good hold downs. Not sure what they were made for, but they are brand new and came in a cardboard box complete with heavy bolts. Might have been ordered for some machine hold downs or for the machining of large parts. No telling what Lockheed Martin paid for them!

Started the right wing today by making the bottom sheeting out of 48 inch balsa @ 1/8" thick. I added 10 inches to the first three sheets for the long wing of the A6M3 Model 22. Last two sheets were shorter as the trailing edge tapered off.

Post by: Lane C. on October 17, 2018, 09:47:57 am
Had to make another fix on the parts kit item. The wing joiner was not cut symmetrical which kinda changes the way it fits inside the first 6 ribs. So, I carefully measured the angle of dangle on the left side I just worked and copied those dimensions over to the right. Fairly disappointed in the Meister wood kit.

In the first pic, a close up shot, you can see the black line. All the wood under that line needed to be removed. I took a small hand plane and trimmed it. That pine wasn't quite as easy to cut as balsa.

In the last shot, you can see how the ribs are cut to allow the joiner to slide thru each one. At the wing root, the cuts are very deep, leaving almost no material to hold the rib together.

Also, you can see how the wing joiner fits inside the ribs on a slant. Kinda of a crzy way to build a wing, but I suppose it works.
Title: Re: Meister Zeke Build
Post by: Joystick on October 17, 2018, 04:01:03 pm
Is that going to be a one-piece wing?

It looks odd to only have one wing joiner.

I would do a line-bore through four of the root ribs on each wing and put in a 1/2" to 1" aluminum tube toward the rear of the wing.
Title: Re: Meister Zeke Build
Post by: Lane C. on October 17, 2018, 05:36:06 pm
Steve, nope, it's two-piece. Otherwise, would have to have a trailer to haul a one-piece 118 inch wing!

Here's a shot I just made late this afternoon. Managed to get the first 7 ribs on the right wing glued down and put the left wing on there. Just to see if both halves lined up - and they do.
Title: Re: Meister Zeke Build
Post by: Lane C. on October 18, 2018, 05:47:31 pm
A little work every day gets the job done. Not much today, but something. Added the last 7 ribs and then added the inner and top spars. The inner spar is between the top and bottom spars that run the length of the wing. The inner spar keeps the wing joiner spar in place and "creates" the dihedral angle. Like I've said before, a crazy way to design a wing.
Title: Re: Meister Zeke Build
Post by: Lane C. on October 21, 2018, 05:58:49 pm
Got the right wing stable enough to lift off the plans and slide on the left wing. Lots more to do on both halves.
Title: Re: Meister Zeke Build
Post by: Lane C. on October 22, 2018, 06:14:05 pm
Spent a few hours in the shop today adding the shear webb bracing across the front of the spar on both wing halves. Not much to photo, but needed doing.
Title: Re: Meister Zeke Build
Post by: dlabby on October 22, 2018, 06:34:53 pm
I thought webs went on the back of the spars. Do you do both sides?
Title: Re: Meister Zeke Build
Post by: Lane C. on October 22, 2018, 06:53:40 pm
Darrell, I guess it depends on how the wing is built and when you add the webbs. Doing one side is OK I guess, but both sides is better. Since the wing joiner kinda depends on both the upper and lower spars plus the inner spar to hold its position, I think it is important to have bracing on both sides of the spar. Meister shows the webb bracing going past the wing joiner by two rib bays and then no more webb bracing all the way to the wing tip. Like I've mentioned several times, the Meister wing design is kinda strange. But, by all accounts, the Zero is their best flyer, so who can argue with that?
Title: Re: Meister Zeke Build
Post by: Joystick on October 22, 2018, 08:00:28 pm
Darrell,

I usually follow the directions unless it looks like the designer didn't follow standard design practices.

Usually, on a wing, the leading edge balsa covering is extended to the spar and lapped on top of it, then webs are applied, with the grain vertical, to the rear, or front, of the spar to create a strong D-tube shape. In that case there is no need to use webs on both sides of the spar, it just creates more weight.

If the spar is in the middle of the wing and the sheeting is not extended from the leading edge to it, the spar construction can be a box, an H, or a C shape, depending on the strength, or stability, required and the weight desired. The box shape is the strongest. It does add a little more weight, cost and time.

On the Zeke, since the main wing joiner is between the top and bottom spar, it would be a good idea to box it in, for the length of the wing joiner, since the gain in weight would be worth it for the additional strength provided by the box shape over the C shape. If round tubes were used, boxing in the top and bottom spars would not be required.

A lot of times the webs are not used in the last 1/3 of the wing to save weight. The strength is not usually required out there.

With the modern engines and larger planes, and to some extent, the covering materials we have today, a lot of the design practices have not been updated. With the high power to weight ratio we enjoy today, we don't need to get insane about saving weight.

The designer has to be aware that the structure only needs to be a little bit stronger than it actually NEEDS to be, more is NOT better. The bottom line is that the lighter planes usually fly better, but they do need to hold together.

"The designer has to be aware that the structure only needs to be a little bit stronger than it actually NEEDS to be, more is NOT better. The bottom line is that the lighter planes usually fly better, but they do need to hold together."

Heavier planes penetrate better! ha. It's amazing how much punishment these models can absorb and still hold together. Not talking about rough takeoffs and landings, but just the high-g turns and pull-outs. I am still surprised every time I see Barry fly my old TBM Zero, wow, all that high-speed jinking and jiving  and she's still holding up!  The wing loading on this current Zero (118 inches) will be about the same or less than the TBM (92 inches).  But the TBM still took off and landed like a trainer. The Troy Bilt Model should have been about 100 inches for the Model 21 it's painted as. TBM made two paint schemes for that Zero, the A6M2 Model 21 and A6M5 Model 52. The Model 52 had a shorter wing and a faster roll rate. The Japanese Imperial Navy didn't really need the folding wing tips any longer as their carrier group was just about Zero after Midway. Most of the earlier Zeros became land-based with a crude application of brushed-on green paint over the light grey.

Some misconceptions about the Zero Sen are still heard on TV shows. One is that the Zero never made any improvements to the engine and pilot protection amongst other items. With the first Sakai 12 engine it was rated at 950 HP. Later, it was increased to 1140 HP on the Model 63 with water injection. As well, armor plate and armored glass were installed behind the pilot's seat and pilot's head. A self-sealing gas tank was also installed behind the pilot's seat. Heavier machine guns with more rounds were added to the Zero in later models. The main reason the Zero faired so badly as the war drew to a close was the lack of experienced pilots. The Zero was still a formidable gun platform in the hands of a pro, even against the Hellcat.

Anyway, the Zero is a cool warbird, despite not being invented here. "Not invented here" is, IMHO, the reason so many seem to dislike the bird.
Title: Re: Meister Zeke Build
Post by: Joystick on October 23, 2018, 09:23:29 am
The Zero was a great fighter and they did make a lot of improvements. Too late for most of the pilots.

It's amazing to see how each side makes adjustments to their equipment in wartime.

I was always impressed with the German craftsmanship. The first German pistol I saw made ours look like cheap toys.

The USA tends to go for the high-tech approach for weapons. When I was working on some missile problems at LM Aero, the enemy was using some low-tech things to defeat our million dollar missiles. Two popular ones that were used to cause us big problems were a Russian built RF transmitter decoy, which was a copy of a $4.50 Radio Shack toy transmitter and a simple candle in a tin can. That is why the State Department has some strange export restrictions on items that don't seem to make sense.

Post by: Lane C. on October 23, 2018, 02:01:16 pm
Steve, I call what the US uses for producing military goods, "The Elegant Solution" syndrome. The F-XX engineers came up with the idea that instead of just having an F-16 braking system, why not run the braking signal thru the Inertial Navigation System? Lots of benefits to that solution they said. Problem was, they almost failed miserably in making it work! haha. Wasn't quite as easy to do it as to say it can be done.

Post by: Lane C. on October 25, 2018, 07:40:02 pm
Finally got to looking at the retract install. This is another job on the Zero I am not looking forward too as the plans kinda leave me cold on the matter. I am copying somewhat another builder's work on RCSB and that has been helpful. The retract plate in the Meister Kit is wrong, so gotta start over with that and then try to fit the retracts best i can. Meister only give "general" cut outlines on the laser cut ribs so, that's not any help. It's just an iterative process of fit and try, fit and try.

First pic is the mounting plate for the Century Jet Models retracts which is wrong for Sierra retracts. I made a paper template of the new plywood plate for Sierra retracts (still unbuilt thus far). Then, cut out the ribs to allow for the whole left retract to fit inside the wing. And lastly, how the retract will be, approximately. Like I mentioned, lots of back and forth, fit and try.
Title: Re: Meister Zeke Build
Post by: dlabby on October 26, 2018, 09:42:53 am
whooeee, those ribs are looking kinda skinny aren't they? Had the same problem on P-51A. Top skin will hold it all together but these retract cavities have got to be a 'weak' area on warbirds when gear is about as thick as the wing. I have full confidence you will get it all worked out; there is a lot of trial and error in this business. haha

Got all the wing servos mounted. Bought some hinges for the flaps. They mount flat on the bottom of the wing. Used a smaller version of these before on the CMP Zero. Work nicely. Last shot is the flap servos mounted in the wing. Won't be long and I can sheet the rest of the wing.

Also got the new Robart 5.5 inch wheels in. They fit with a small amount of room to spare.

Spliced up some sheeting, cut to size, and glued it to the top left wing. Used yellow Carpenter's glue. Added pins and then weights to hold it down. Two hours and she'll be dry.

Added another 6 inches to the sheeting for the extended Model 22 wing. Marked the bottom of the sheeting with rib locations for glue. Applied glue to both the sheeting and the ribs to make sure I got plenty of glue on there.

Not that much sanding. Mostly #11 blade and straight edge cutting. 100 MPH pass, yes indeed!

Got the sheeting glue dry and trimmed it down to the wing. Popped loose the flap to see how it looked. Added the aileron for grins, still needs sheeting on the top. Assembled it to the other wing for comparison. Wing is straight and true so far.

Thanks Darrell. The wing is finally shaping up.

Got the left wingtip in the works. Laminating it out of a plywood core and balsa sheet glued with yellow glue for ease of sanding to shape. Traced the shape off the plans on waxed paper. Transferred that to heavier stock to make a template. Then began the glue ups. I hope this works! Hopefully, the hard plywood core will help keep the shape while I sand off the excess.

Got the LE glued on and shaped. Also worked the wing tip some, but not glued on yet. Just tacked it in position to check fit. The wingtip is pretty big and fairly hard to work. It uses lots of balsa! Will have to glue it on permanently to do the final fit and shaping.

You know me, I do a little something on the Zero every day. Finished up the left wing tip today. Had a fair amount of shaping to do off the wing, and then glued it on for good to do the final sanding. Even with a 60 grit sander stick, took LOTS of sanding to get that last bit level with the wing. Also merged the leading edge with the wingtip.

Had a setback later today. Sheeted the other aileron and it warped on me while the glue was drying. New bottle of glue and too much moisture content? Not sure why it warped, but will have to make a new one. Not a major setback, will take a few hours, but has to be done. Oh well, the left wing was going too good I suppose.

Steve, like I say, might have been too much moisture all in one spot. Not really sure. But, something went wrong. If it had to happen, the aileron is a good place for it as it isn't a total pain to rebuild. No cut ribs or anything I cannot make. Just time. I may take a photo later and post it.

Got the 24x24" sheet of 0.062" G10 in today from McMaster-Carr. I am using G10 for the flaps since the plywood I started to use is bowed and kind of a pain in the nose. They are split flaps and don't have any airfoil shape to them. They just have some small stiffeners running chordwise on the inside and drop straight down. G10 won't warp or twist. One of the flap outlines is on the sheet. Also ordered a few 1/4" STEEL wheel collars since you cannot find them in the RC vendors. Those are all soft brass that strip out from over tightening the set screws. Steel collars won't do that.

Sorry, it's only dry enough for a 39.9999999999999999999999999999999999999 lb plane. You'll need to wait 1.2682 days for it to dry out enough for a 40 lb plane.

Haha. It's not the basic movements, but the reactions to unusual things that might happen that seem to be a problem from not flying very often. Muscle memory is good for turns, level flight, loops, rolls, landings, and stays that way quite a while. But, there is no muscle memory for engine quitting right after takeoff or such as those things rarely happen. That's what gets ya. Ha

After a few days off from working on my old truck, got back on the right wing sheeting. Spliced together several sheets of 1/8" balsa and trimmed to the basic outline. Used Yellow glue and put the weights on the sheeting hold her down overnight. Next will be sheeting the upper/lower front half of the wing. Won't be long till I can glass both wing halves.

You need to take a day off and go fly. The field is dry, the wind is light, it's relatively warm, it's perfect flying weather. Vacuum off the dust on one or two of your many planes, they want to go fly.

Back to sheeting. Wing is now sheeted. Still need to build the right wingtip and add the leading edge. Plus, hinge the aileron and flap.
Title: Re: Meister Zeke Build
Post by: Lane C. on November 24, 2018, 06:02:22 pm
Today, got the leading edge glued on and dried. Used yellow Carpenter's glue. Also, hinged the aileron. Will get back out there and shape the leading edge with the mini-plane on Sunday. And, will make the right flap out of more G10. The plywood shape is the inner core of the wingtip for strength. Ordered some thick balsa sheet for the top/bottom layers of the tip from Balsa USA. Will have to wait a few days to get that delivered. Plenty of other work to be done.
Title: Re: Meister Zeke Build
Post by: Lane C. on November 25, 2018, 06:24:09 pm
Got several items done today on the right wing half. Cut the new right flap out of G10 and hinged it. Hooked up the servos for the aileron and flap with linkages. Cut out the sheeting and installed the right retract. I decided not to shape the LE until I get the wingtip built up and glued on so they match better. Later this week I'll have the new balsa to make the wingtip. Put both halves together to see how she looks. Won't be long till I can put the wing on the fuselage to see what it needs to bolt the wing in place.

Got the wing fitted to the fuselage today. Took an hour to do this as the wing and glass fuselage were not really sympatico! Really had to trim the trailing edge of the wing to make it fit the glass. I expected some trimming, but not much. However, got it rough fitted. There were some gaps between the wing and fillets and I hope to make those smaller once the wing is bolted down. A bit more of a milestone with the wing on. Last pic is right side up. Ha

Santa is a one-man-band!

Still fitting the wing to the fuselage. Little changes here and there to get a good fit. Got the wing hold down hardwood mocked up to the bulkheads, one side. Bolt will come down thru the wing into the hardwood and into a Tee-Nut. The square cut on the forward end of the wing saddle is for the tongue on each wing to slide thru. In Meister-World, the "tongue" serves about the same purpose as dowels on most other brands of kits and ARF's. Cannot comment too much one way or the other till I actually use them inflight. I cut it down (up in the photo) bit-by-bit to get the wing to fit the saddle. After I am happy with the fit, I'll epoxy a piece of 1/4" plywood on the other side of the glass to reinforce the tongue poke-thru. I cut back the glass saddle edges to try to reduce pressure on the wing and allow the wing to settle on the saddle as tight as possible. Last photo is a 1/16" plywood reinforcement on the back of the wing to keep the sheeting intact. I'll cut it in the middle after sanding to the wing sheeting. Still waiting on the balsa shipment to build the wingtip.
Title: Re: Meister Zeke Build
Post by: Lane C. on November 28, 2018, 06:09:47 pm
Stayed on it later in the afternoon. Got the wing bolted down with 1/4-20 bolts and Tee Nuts. This pulled the wing down tight on the fillets. Mostly. Still have a bit of gap way up front where the fillets take on a tight curve. Getting close to being "on the gear." Maybe tomorrow.

Did that mess up the incidence?
Title: Re: Meister Zeke Build
Post by: Lane C. on November 29, 2018, 04:42:28 pm
Steve, since the wing makes contact with 75 to 80 percent of the fillet, then it likely means just my forward wing contour is off from whatever wing was used to create the fuselage mold. Especially the leading edge which can be shaped a bit different depending on who is doing the shaping. I can test the actual wing incidence vs the horz tail incidence after I get the plane upright and setup. I built the tail at 3 degrees more incidence than the wing (fuselage fillets at LE and TE) so the tail will fly high and keep the nose down at higher speeds because flat bottomed wings generate more lift than semi-symmetrical wings as speed increases. So, bottom line, I don't think it will mess up the incidence.
Title: Re: Meister Zeke Build
Post by: Lane C. on November 29, 2018, 06:26:41 pm
Got the wingtip balsa in from Balsa USA tonite. Along with some more plywood sheets (12" by 48"). Will work the wingtip tomorrow. Those are 1" by 4" by 36" balsa planks. Nice looking lumber. Even more $$$ than Lowe's & HD lumber! If you order from Balsa USA, be sure to order at least $100 worth as you get free shipping. Might as well order extra CA to push up the $$ figure to make $100. Shipping can be high on 48 inch items like that plywood. So, might as well make a big order. You cannot find large sizes of balsa or plywood at Roy's or JT's.

Post by: Lane C. on November 30, 2018, 06:54:27 pm
Stayed on the wingtip all day doing the glue-ups required. I allowed about 2 hours per glue-up for the yellow glue to dry. Then shaped the wingtip on the spindle sander to get the outline done. Will take a fair amount of shaping to finish it off like the left wingtip.

Thanks guys! I managed to flip the plane over on the gear by myself today. Really wasn't bad. I needed to test the incidences on the wing and tail to see how all the extra work on the horizontal tail turned out. Looks like with the wing at 0 degree incidence the horizontal tail is +2 degrees incidence. This is fine. The tail should fly a bit high with this setup. I think this looks cool and will help the plane stay level at higher speeds. I dug out the canopy for a few pics. And lastly, turned out the shop lights for a stark silhouette shot.

The US Mail dropped off my roll of glass cloth from Ziroli. It's 30 feet by 3 feet and plenty to cover the wing. They call it 1 ounce cloth. Also pulled the DA-100 out of the box and hung it on the Zero. Looking forward to hearing this one run.

I need to make a faring under the wing where it touches the fore and aft fuselage. It's a bit complicated being that the wing is in two parts and the fairing needs to be split in the middle. Not exactly sure how I will accomplish this yet.

Looks like you are doing what first came to my mind. Sections of soft balsa carved and sanded to shape and mounted (glued) to the wing bottoms and glassed. Good luck.
Title: Re: Meister Zeke Build
Post by: Lane C. on December 07, 2018, 08:16:03 am
Hi Darrell, if this were a 1 piece wing it would be much easier to make that fill. And, not really exactly sure how it's supposed to look. I think what I have is close to correct based on the few photos I've seen. That balsa "hump" needs a bit of flattening out to make it a bit more subtle. It won't really show much on the assembled model after painting, so, not going to have a gran mall seizure over it! haha. And, if I put the centerline gas bag on there, it will draw the attention rather than the fill area. Meister has the Model 21/22 gas tank in fiberglass for $75 I seem to recall. It's the smallest details that seem to take the longest!

And one more thought, sometimes you have to know WHEN TO QUIT messing with it! You can go from not too bad to totally wrong pretty quick with balsa. And once it's glued down, LEAVE IT ALONE! Make all your changes while you can before gluing.

And, the thing that makes this part hard to get correct is that the Meister is a flat bottom wing vs semi-symmetrical on the full scale Zero. It changes the look of the bottom area. The other Zeros I have had are almost dead flat in that transition area between the wing and fuselage. Makes the model easier to build for the ARF factory.
Title: Re: Meister Zeke Build
Post by: Lane C. on December 08, 2018, 05:45:25 pm
Yesterday was a rare day that I did ZERO on the ZERO! Ha. Today I moved forward to the other fill area and kinda figured it out as I went. This part will stay on the fuselage and get glassed over for strength. Only half done with it. That's the scoop for the oil cooler.

Title: Re: Meister Zeke Build
Post by: Lane C. on December 09, 2018, 04:29:50 pm
Finished the front fairing today and epoxied it to the fuselage. Then laid some heavy glass cloth over that area with Z-Poxy.
Title: Re: Meister Zeke Build
Post by: Lane C. on December 14, 2018, 04:18:38 pm
Well, seems we had a slight interruption of service, so I'll try to catch up on progress made. Got the forward fairing finished and the air scoop for the oil cooler glued on. Then moved to glassing the wing halves. I bought a 30 foot roll of glass cloth from Ziroli and it's nice material. I covered the left top and bottom wing half in one piece and used Z-Poxy to glue it down. Z-Poxy is really the best finishing resin. Did the bottom first, then the top. Once one wing half was done and dry, I put the wing back on the fuselage to look it over and take a few pics. Results speak for themselves. Zeke is 85 inches nose to tail as she sits, and add another 6 inches with the spinner later on. Now, I need to glass the right wing half and then the ailerons. After glassing, then goes to primer, but no hurry on that due to the cold weather setting in. Got things like gear doors to fit and other items on the fuselage to add. Lots of details from this point forward.
Title: Re: Meister Zeke Build
Post by: Lane C. on December 15, 2018, 07:50:27 pm
Moved to the bottom right wing today with the glassing. Thinned the Z-Poxy with a small amount of SIG Butyrate thinner to make it go farther and penetrate the balsa better. One more side to glass, then the ailerons.
Title: Re: Meister Zeke Build
Post by: Lane C. on December 16, 2018, 07:02:55 pm
Got the top right wing half glassed today. Then, put the wing back on the fuselage for grins. Also looked at the gaps along the fillets, both sides. Still need to fill those gaps, even though they aren't major - I just don't want to allow gaps between the wing and fillets which could permit wing movement (increasing dihedral angle) under high-g maneuvers. The removable spar, fillets, rear wing bolts, and forward "tongue" all work together to keep the wing intact.
Title: Re: Meister Zeke Build
Post by: Lane C. on December 18, 2018, 06:01:17 pm
Got to the gap filling today, between the fillets and wing. Used Hysol. Sanded the underside of the fillets with 80 grit, wiped with alcohol, then applied the Hysol. Covered the wing with Saran Wrap first. Takes 24 to 48 hours to really dry hard. Will sand off excess later.

Once the wing was on and tightened down, it squished out the sides. Took a finger and pushed it back in the gaps. Hysol is Thixotropic, I think it's called. Which means, it won't run due to gravity. It's used on aircraft and autos. Expensive glue, but one of the best. It's basically a two-part epoxy and it comes with a caulk gun type squeezer and nozzle to apply it with. The nozzle mixes it as the two parts come out the tubes. Nozzles are one use only, but come in handy for jobs like this.
Title: Re: Meister Zeke Build
Post by: dlabby on December 18, 2018, 07:18:19 pm
Boy, you got that right about the nozzle and cap. After a few uses it is a mess especially if you don't finish the tube and set it on shelf. Really expensive when you can't use it all---like on small intermittent jobs. That wing is looking great. Barry and I had 2 great warbird flights together today. Excellent wx.

Decided to close the cuts in the wingtips for the position lights. I never made any holes in the wing to route the wires, so won't need the cutouts. Just filled-in with scrap balsa and used Dolphin Glaze to smooth over. Also had a low spot just behind the leading edge and started filling that with Dolphin Glaze too. Will take several applications to fill. But, not to worry about weight of the bondo as it's forward of the CG and I will be adding lead up front anyway when I do the final CG determination.

Darrell, I don't do FaceBook. Haha.

Got some speedbumps/blisters in from Fiberglass Specialities today. Got two sets of two types. Looks like the smaller bumps will look better. These are to cover the holes in the cowl for the spark plug caps. I could leave the holes there and just paint the caps black and wouldn't show much. But, the speed bumps would keep air flowing past the cylinders, so will likely use them. The cowl is black so that will keep the speed bumps from showing up as much. Likely no one will know the difference anyway. They are a concession to keeping the engine running cool vs scale appearance.
Title: Re: Meister Zeke Build

Got the drop tank in from Meister today. Did a quick mockup of it under the wing. Will take some fitting for sure. The shape at the aft end is too pointed. Needs to be reworked. Hmmm. I will say the tank is VERY solidly built! Kinda heavy too. Won't be on for the maiden flight, for sure.

Bought some more Dolphin Glaze at English Color. Good stuff.

I sanded off the rough glass joining seams on the gas tank and hit them with some grey primer. May not show up well in pics, but looks better in person. I flipped the bird over and sat the tank on the wing as far forward as possible. I need to find a way to attach the bomb rack to the wing and also the tank to the rack.

For Barry. Yes yes yes. Any sanding sucks.  Sucks.
Bad for the wrist and elbows. But normal humans it's a good sorce of entertainment.
My small experience with it was fairly easy. Lots of sanding and reglazing and priming and more sanding. It was with my Zero wing that you Darrell painted and it came out looking perfect.

Yes, I borrowed a little of this stuff from you to make a fillet. As I remember it, it was very hard and difficult to use/form. I have been using the red glaze stuff. It sands and feathers nicely.
Title: Re: Meister Zeke Build
Post by: Lane C. on January 14, 2019, 10:58:21 pm
Darrell, Dolphin Glaze is easy to sand with a 60 or 80 grit sanding stick. Trying to use a fine grit at first is not the best way to do it. After you get it roughed shaped, then switch to finer grits. Z-Poxy is really harder to sand than Dolphin Glaze.

Another builder on another site asked about the primer I used. I use Advantage 301 Grey high build primer that Lee Rice told me about several years ago. It is acrylic lacquer and takes Advantage 102 as a reducer. I shot a couple of pics and will post them here. Also in the pic is Advantage 190 oil and grease remover you should use before spraying primer or paint. Really cleans finger prints and other stuff off before you paint. Also cleans exhaust mess off your plane after a day's flying. Lee steered me fine on all three products. English Color stores has these products.

I used this Advantage 301 primer for the first time on my current biplane build. It is great stuff. Sure glad I got a good respirator mask from Harbor Freight.

Title: Re: Meister Zeke Build
Post by: Lane C. on February 04, 2019, 05:03:10 pm
I've been thinking of a way to mount the centerline gas tank on the wing and still have the wing in two halves for transport. So, I found some PVC brick molding and trimmed the ogee off the front edge with the table saw and epoxied two lengths together. Then I sat the tank on it and marked the outline. Cut that outline on the band saw. Then sliced it down the middle and began to fit to the inside of the tank neck. The inside of the tank neck was very uneven and needed lots of Dremel sanding and cutting. Anyway, got it to fit inside the tank neck fairly snug. Next I will see how to permanently mount the PVC halves inside the bottom wing root. However I manage to get them to fit in the wing, the PVC halves will stand proud of the bottom of the wing about an inch and the tank neck will get screws drilled into the PVC halves after I assemble the Zero at the field. Won't be jettisonable, just fixed.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 05, 2019, 04:43:40 pm
Did more on the tank mount today. Almost finished. Still needs to be glued in place. After gluing, will add some sheet metal screws to the tank neck thru the PVC to hold in place.

Title: Re: Meister Zeke Build

Got the bomb rack tacked to the wing sheeting with thick CA. Then pulled the wing off and opened up the top sheeting so I could get some epoxy on the PVC to really lock it in place. Added some glass tape and Z-Poxy over it as well. I'll glue the sheeting back on after I get the bomb rack secured. Then do the other wing half.

Barry Meister, won't be long! Hopefully this Summer. Got the tank mount finished this morning. A static-only item until we clear the flight envelope and make sure the engine runs OK. will look great with the tank on and going by at 100MPH! Tank is on there very solid! Going to hang the great on a flip over for a few pics later.

As usual, very nice craftsmanship displayed in your zero build Lane. It kind of surprises me that a Meister Scale project would be as difficult to complete as this one has proven to be.

I've wanted to build a Meister ME109 for a long time, but with limited build space and building tools such a project has been shelved and I picked up a Phoenix Model Stuka instead. Work on this new project to begin soon. No retract to deal with WooHoo! ;)

Hi Darrell, yep, gotta keep moving forward!

Got the throttle and choke servos setup today. Still need work, but I think they will work like this.

Had to flip the red arm on the throttle and will make a new G10 arm for the choke.

Got the linkages made today. All pretty straight forward. On the G10 for the choke, ended up using another steel arm from a DLE carb.

Spoke to Barry this afternoon. He suggested changing the 4-40 clevis to a HD 4-40 Ball Link to make sure the throttle linkage is secure in all phases of flight! Couldn't hurt anything to change over so I did. VERY heavy duty setup now.

Been thinking on how to mount the gas tank in the engine box. Decided I needed some semi-hard foam to surround it with. I cut the foam to center the tank in the engine box and made it fit very snuggly. With a velcro strap across the back should hold it in place fine.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 21, 2019, 08:29:12 pm
Made a platform for the ignition unit on top of the engine box. Although, it may be a mounting spot for the lead ballast the Zeke will surely need to get the CG around 30 percent MAC. I'm thinking 5 pounds minimum and maybe as much as 10 pounds. I'll have to wait till she's been painted and all finished to see how she balances out.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 22, 2019, 08:58:41 am
With a suggestion from the guys on Radio Control Scale Builder for a novel way to allow for lots of lead weights, I am going to build a weight box along the lines of my basic sketch below. Since there is space over the engine on the twin cylinder, I can come forward with the weights. The more forward the weights go, the less weight I'll need to make the CG work. The 5 lb weight would go forward of the 2 lb of course. This is a rough sketch. I've already seen some better ways to build the box. But, that's why it's good to make a sketch of ideas so you can evaluate them without ruining expensive 1/4 inch RC plywood (I might be able to salvage and use the plywood square I've already cut). The next step will be making a model out of paper templates. Then, the actual build.

I recommend going to RCSB and browsing around to see some awesome Scale RC work. It's free to browse but you may have to sign on as a guest. To join, it's only $20 a year and you can easily get $20 worth of ideas and problems solved in the process. Unlike the club board here, there are always dozens of onlookers from around the world (they are UP while you are asleep) to read your questions and comments, and help solve your engine and radio problems, for example.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 23, 2019, 02:38:05 pm
With a basic idea down on paper, the next step is to get some dimensions for the final Denny Box. I say Denny Box since that's the name given to a weight box used by a RCSB builder named Denny who uses this idea all the time on his warbirds. A 5lb diver's weight is laid on top of a plywood base to see how far forward the box can be and still fit the spinner and cowl. As the photos show, the weights come almost to the spinner back plate and can be one atop the other. That's 7 pounds of lead as far forward as is possible. Of course, the farther forward the weights, the less weight is needed to achieve a particular CG number. Also to be considered, the cowl has to be able to be installed over the weights without interference. Now with those figures, I can make a 3D mockup with cardstock. With the cardstock mockup in place, it looks like it's going to work out pretty well.  Next will be cutting the final parts out of 1/4 inch aircraft grade plywood and gluing them up.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 23, 2019, 07:53:51 pm
Got to cutting plywood today. I cut the parts and laid them out. Started gluing the forward floor to the side panels and then the center cross panel and finally the aft floor. One more small cross panel on the front end tomorrow and then will taper the side panels. A little bit a day gets the job done.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 24, 2019, 09:48:24 am
New day and the glue is dried. Denny Box on the Zero with just a bit of overkill on the weights! Still a few things to finish up. I hope I do not need this much lead on the nose! A few other items ahead/forward of the CG that will offset a heavy tail end are the retracts/wheels, cowl, spinner/prop, Rx and engine ignition batteries. I'll put it all together soon to see exactly what amount of lead the desired CG requires. Desired CG is 25 to 30 percent Mean Area Chord, always a safe bet for a maiden flight.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 24, 2019, 06:05:43 pm
Finished the Denny Box this afternoon. After all the glue ups, I cut some welding wire and pinned the box all around. Then drilled the box on top of the engine box and added screws to hold in place. The front floor actually rests on the very center of the engine with some relief cuts to keep the fins off the box. Just needs some Z-Poxy primer coat and then some glass cloth for strength. Since I don't know how much lead she will require, I'll have to start off with 5 pounds on the CG test and go from there. Maybe masking tape the lead  in place for the CG test. For the final deal, I'll bolt the weights to the Denny Box.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 25, 2019, 12:44:10 pm
I came up with a way to hold down the diver's weights in a way they won't come loose inflight. Also added a velcro strap to hold the front of the Denny Box in place should it work loose. A belt and suspenders approach, you might say, but an inflight change in the CG would be disastrous.

Title: Re: Meister Zeke Build
Post by: Lane C. on February 25, 2019, 03:48:11 pm
Got the Z-Poxy out and gave things a prime coat to keep the gas spills out.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 26, 2019, 07:44:22 am
Went out to the shop this morning to see if the Z-Poxy was dry, and it was. Sanded the edges a bit and put it on the engine box. Matches the rest of the "bright work" as they call it on boats. A little more sanding and another light coat and that will be that.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 27, 2019, 05:41:15 pm
Added the 2nd coat of Z-Poxy to the Denny Box and servo mounts today. It dried and i reassembled them on the engine box. Also, added some Velcro straps to hold the gas tank in place. Also, the Velcro strap under the Denny box is shown better in one photo. A few almost the same pics of the Denny Box as shown before, but all Z-Poxied and back on the engine box. On to another detail on the list, next.

Made the head rest/roll bar this morning. Used the Meister Booklet to find a drawing. Made a drawing to size and went from there with cardstock and then balsa. Sheeted it with 1/64" plywood. I feel it's pretty close to scale.

Gotta have a pilot figure! Bill, from Aces of Iron has been in my pilot box for 10 years. I started to paint him, but never finished. He was too big for the CMP Zero. He's a full 1/4 scale pilot, but only a bust figure. Boosted him up 2 inches to look normal in the seat. Going to set the cockpit up long as I'm in that area today.
Title: Re: Meister Zeke Build
Post by: Lane C. on February 28, 2019, 08:27:01 pm
The PVC seat is kinda weak and flimsy on its own. So, made a balsa box frame to give it some support in the cockpit. Frame won't be seen, so no big effort to make it scale in appearance. Installed the floor and side panels to check out how they all fit together. It's coming along! Will paint the cockpit Aotake Blue.

Steve, I know, he's getting impatient. But, soon the weather will begin to warm up and I can do some outside priming and painting. Hope to have all the building done by then. Would be neat to have The Hell Bitch II ready for static display at the Scale Meet this year! That would give me a target to shoot for anyway. Doubt I would have time to get her flown before then.

Just cannot seem to stop the detailing of old Bill. Too cold to work in the shop, so worked in the house. Added some more details to the chute harness. The white stitching was too bright, so had to tone it down a bit. Used some very thin black and painted it on in layers.

With your hangar of great scale planes, it would be almost criminal if you didn't enter and fly something in our local scalemaster contest. This is one of our biggest drawing events and you would contribute significantly. You can also enter a second plane in 'static'. Last year the static scores got lost; I plan on that not happening again. Your work is certainly worthy of 'showing off'. Give it some thought.

One of the smaller details in the cockpit was fitting the instrument panel to the glass fuselage. These two parts did not match up perfectly, so I built-up the glass fuselage to match the panel. Ended up adding 3 layers of Dolphin Glaze to make the match up. I made dummy top instrument panel to use as a guide for the Dolphin Glaze and screwed it to the fuselage. Then pulled that off and replaced it with the instrument panel. Once painted it will all look better.

Made some dummy gun butts for the instrument panel today. Primered all the panels, floor, seat, and headrest. Be happy to move on from the cockpit to work on the gear doors.
Title: Re: Meister Zeke Build
Post by: Lane C. on March 11, 2019, 07:43:56 am
Got out the Paasche airbrush and painted the side panels with a medium green. Kinda of a test and it looks pretty good. The Aotake Blue seemed to be a bit much and I cannot find any cockpit photos of original Zeros with the Blue shade. The Blue is used in the wheel wells and flap areas. So, found plenty of cockpit photos of the green shade. But the green shade varies with each panel. So, will look for some lighter green to paint the instrument panel. This isn't a Top Gun build, but like to have some fun now and then with the paint.

Must be something new here to post. Hmmm, I been looking at the gun butts on the main panel and decided they were too big. Cut them out and made new ones. Added charging handles, masked off, and reprimed.

Bill was sitting a bit too low for my likes. Moved him up 7/8 inch. Much better.

Going the find a different shade of green for the instrument panel. Gun butts will get black or charcoal grey paint after the panel gets the right shade of green. And of course, all the instrument faces in the recessed spots.

Looked at the Blue Texas Sky today and decided painting weather is almost here. Dropped the cockpit work and got on making the gear doors. Once I get the doors made, I can start the primering of the entire Zero, assuming the wind stops and the temps rise! Used the plywood doors in the Meister kit as a pattern and modified it from there. Got the left door cut, shaped, and sanded today. Will work to attach it to the gear leg somewhat like the real deal Zero. I just take it one step at a time till it looks right.
Title: Re: Meister Zeke Build
Post by: Lane C. on April 02, 2019, 04:39:55 pm
Back to the gear doors today. Made a plywood liner/stiffener for the door and epoxied in place with 30 minute. This gives something to mount the door attachment brackets to and keeps the thin aluminum door straight. Made the brackets out of 0.032" brass sheet but will remake them out of steel. The doors will function fine like this. Need to refine the brackets.

Bought a HS-7654SH Ultra Torque servo for the flaps. The Futaba 3305's just wouldn't handle them. This one has 333 inch Oz of torque on 6 volts and over 400 on 7.4 volts.

Things are moving along.

But wait ... there's more! On the doors. Found some roof flashing in the parts box and remade the brackets out of that. Made them to look like the full scale Zero brackets. Also made a cover for the retract base. Now, to do the right side gear!

Now, working to get the flaps working. These are HUGE flaps and kinda heavy. Had to buy a 333 to 402 OZ/INCH HiTec HS-7945 servo to pull that load. Having to try a few different test settings for a control horn to get enough leverage. Got some good results today.
Title: Re: Meister Zeke Build
Post by: Lane C. on April 10, 2019, 03:52:18 pm
Got back on the flap today. Managed to get a good setup with the use af that dummy control horn. Made a new horn out of G10 and set it all up again. Put the servo cover on and widened and elongated the slot. Great results and very little servo noise. I'm going to call this done. Now to the the right flap.

Got the fuselage about ready for some grey primer. Glued the headrest/roll over bar on and sanded the fuselage with a Scotch-Brite pad. Fuselage is mostly primed, so will only give it a light coat to see how it looks with an even coat of flat primer. Maybe get some primer on soon. This afternoon wouldn't have been bad, but wasn't ready early on. Too late in the day!

Went to Home Depot yesterday and bought some finish color - grey. This is a light grey as I want to be able to get a good "visual" of the girl as she destroys the other warbirds out there. Sprayed the drop tank for a test run and laid some white printer paper out for a color comparison. It's definitely grey!

Title: Re: Meister Zeke Build
Post by: Lane C. on April 27, 2019, 09:28:11 am
I started the spot putty job yesterday to get all the little holes and imperfections cleaned up. I used a half dozen small batches of Dolphin Glaze for the spot work. Works nice. Also sanded the entire wing halves to get ready for the final primer coats. But, winds are 15-20 today, so, won't get there yet.

Gave the wing a final wipe down with Advantage 109 Oil and Grease Remover. Lee Rice told me about that product years ago and it's a great item. Cleans off all finger oils before painting to keep fish-eyes from forming. You can use it at the field too as it really cleans off the bottom of your gas engine plane!

Yesterday, it looked like the wind was going to blow all day long, but at 1PM it abruptly quit! So, I opened up the shop and got back to spraying primer. Got the final coats on the wing halves and set them aside. Then drug out the fuselage and hit it with primer. Fuselage looks pretty good! Needs to have that primer sanded on the tail end for sure and maybe a couple more coats sprayed and sanded some more to even out the minor defects. Forecast this morning called for winds Mon, Tues, and Wed. Dang!

I wasn't quite happy with the head rest-bullet deflector so added some meat to the aft end. Looks more like the Zero now.

Steve, Wow, never thought of looking up YouTube for a Zero headrest detail shot! What I had first was pretty close. All I needed to have done was the put a slight taper from front to rear and make it a bit longer. I had guessed that it came to a point at the rear end to deflect bullets but apparently it didn't. Anyway, guess I'll stand pat with what I have as I am now in the final paint phase.

There is so much on the internet that it's hard to believe.

The CAF Zero is only one of five flying today. They put a Pratt & Whitney R1830 engine (comparable to the original Sakai engine). Oddly enough, the fact that Japan had a contract with Pratt & Whitney before WWII in which P&W provided engines for fighter planes and other aircraft. It is, therefore, conceivable that some of the planes participating in the Pearl Harbor attack could have been powered by American engines. It's a small, small world.

There's LOTS about Dec 7, 1941 that's VERY INTERESTING, mein herr, VERY INTERESTING. I won't spoil anyone's illusions about what happened that day. Ha. Lane

Got the Aotake Blue on the gear doors and flaps today. First laid down some silver as a base and then the Model Masters 2119 Interior Metallic Blue over that. I think it turned out nicely.

For those not familiar with the Aotake colors, the Japanese Imperial Navy used the Aotake coatings to preserve the aluminum aircraft and it was seen on about every bare metal part of the Zero. We used a similar coating to prime the aluminum before painting. But the Jananese version was really strong stuff and is likely what has preserved any wrecked Zeros found in jungles after the war. There was a shade of blue and a shade of green Aotake used mostly and other shades as well. These colors differed mainly based on the manufacturer doing the mixing of the colors. If you ever see any photos of a well restored Zero, they will show the Aotake in the wheel wells, gear doors, flaps, cockpit, and other areas.

As a former employee of Pratt & Whitney Aircraft, I can't standby and allow someone to slander the reputation of this iconic company.
PWA never supplied engines for Japanese fighters or bombers. This an easily be confirmed by checking two books that are considered the encyclopedias of WWll aviation. William Green's "Famous Fighters of the Second World War" and "Famous Bombers of the Second World War". Both books go into great detail in the development and evolution of the WWII aircraft. No front-line Japanese Aircraft was ever powered by PWA engines. As a side note, the porotype Messerschmitt BF 109 was powered by a Rolls-Royce Kestral engine.
Even had PWA wanted to do business with Japan, it really couldn't. From 1938 on, the US imposed increasingly harsher embargoes on Japan. As early as 1938 the Department of State notified aircraft manufacturers and exporters that the United States Government was "strongly opposed" to the sale of airplanes and related materiel to Japan. In 1939, the non-binding embargo was extended to materials essential to airplane manufacture and to plans, plants, and technical information for the production of high-quality aviation gasoline.
So PWA could not have legally supported Japanese aviation and was actually building up its capabilities to support the allies in the years leading to WWII. While building up production capability from a civilian economy to a war time footing, PWA was developing the R 2800 radial engine. The engine that powered the Corsair, Hellcat and Thunderbolt.

I'll tell you something that WAS propaganda from the War Department during the war. They put out the story that the Zero was just an inferior modified copy of some USA fighter! In other words, they attempted to further denegrate the Japanese Military. Of course, this was to be expected. But, the Zero was a PURE, ORIGINAL design that originated from the Japanese Imperial Navy. And I need to add that the Zero was ALWAYS a Japanese Navy aircraft. There were ZERO Japanese Army Zeros! Ha. They were simply painted green after Midway where they lost much of their carrier fleet, and were forced to operate from land. Most assume that there were Zeros by both arms of the military. The Navy was the one to blame for the lack of more horsepower in the Zero because they refused using the more powerful radial engines being reserved for the newer fighters. Although, by the time that a more powerful engine might have been placed in the Zeros, most of their best pilots had already perished.

I'm not saying the CAF is correct. I also had no reason to believe that what they said is in error, they are the experts who are rebuilding the Zero. What they said seemed reasonable to me.

I also have not verified everything on every website that I have been to. Life is too short. There are billions of errors on the internet.

They are the source of the information on the Zero. If you think they are in error, you need to contact them to correct it.

I have also not verified that you're correct. I can't prove that you are. They claim it is a fact, you need to find out where they got their information.

I've also been in the military for over 20 years and have actually been places and done things that our government, all the way up to and including the President of the United States said, and denied to the world, that America has not been involved in. Who is correct?

That's your opinion.

You have no way to prove beyond all doubt that the CAF is wrong any more than I do. You also can't possibly know what our government did once they had the engines over 70 years ago. I base that on my own personal experience after 20 years in the military and 18 years at LM Aero.

I'm also not going to research every fact on every article that I see to verify them for accuracy. It's not necessary, nor is it practical. If something looks suspicious, I do consider the source, I may question it, or leave it out if I'm not sure.

I'm only posting information on a closed site that only about 20 people read, this is not CNN or the NYT, nobody dies.

If DLE says their engine produces 3.7 hp, I'm not going to put one on a dynamometer and verify it to be true.

Weather was FINE today! Painted several hours on the Zero.

The left wing needed one more coat as it had some primer showing thru.

Painted the gear doors on the outside.

Gave the tail cone another coat as it had some grey spots showing thru too. Also painted the tail wheel and shroud.

Painted the bottom side only of the fuselage so it could dry a few days. It's dry to the touch, but really needs a few days to dry or it sticks to whatever it's sitting on.

Painted the cowl today with more Behr house paint from Home Depot. They computer matched it to the M&M Models color chip book page for Japanese aircraft. It's called "Blue Black" and it looks kinda charcoal to me. But, this is supposed to be authentic. I also sprayed the inside of the cowl flaps since they will show.

I made an improvement on the gear doors between the upper and lower plywood stiffeners. Since the lower piece was an afterthought, that joint was weak and allowed the aluminum to flex at that spot which might generate a metal fatigue crack later on. Just a bit more plywood and epoxy and I hope it will hold. More paint required over that repair. Won't interfere with the strut legs.

To help cure the latex paint, I use my "poor man's autoclave" camper shell in the sun. Left the fuselage and cowl out there for 3 hours, but had some errands to do this afternoon. Will leave them in there longer on Wed. All day out there a few days will really help dry the paint deep down.

Title: Re: Meister Zeke Build
Post by: Lane C. on May 15, 2019, 03:18:15 pm
Put the fuselage and cowl back in the autoclave and did some painting on other areas.

One of the detail areas I kinda dreaded messing with is the Aotake color in the wheel wells and flap areas. This required quite a bit of precision masking and then a silver base coat followed by the 2119 Interior Blue oil based Model Master paint. Also painted the spinner and backplate silver. The nose of the spinner will also get a red application about the halfway up point to the tip.

Got the paint mask package from Callie Graphics today. Went out to place them on the Zero. I taped them in position for now and feel they are pretty close to the final position. Too humid and too windy to paint. And more rain coming. So, guess that will be a few more days to get blown past and dried out.

Post by: Lane C. on May 22, 2019, 11:23:26 am
Starting to look like a Zero! Painted one Hinomaru on the right wing bottom. Took a few coats to build up but that's the only way to keep the paint from bleeding under the paint mask. Better to take your time and build the color up slowly. Paint mask pulled off the grey paint, but it looks like weathering!
Title: Re: Meister A6M3 Model 22 Zeke Build
Post by: Lane C. on May 22, 2019, 09:17:09 pm
I continued on with the markings. Painted the Hinomarus on the fuselage and the tail numbers.  The paint masks really held on tight and pulled quite a bit of paint off. But, the Zero is supposed to look crude, and it's already on its way! Callie's paint masks are way too sticky. She changed them a couple of years ago because some customers complained the old material wasn't sticky enough. I'd like to request her to use the old material next time.
Title: Re: Meister A6M3 Model 22 Zeke Build
Post by: Lane C. on May 24, 2019, 09:14:34 pm
With the paint masks pulling up the paint, and since the Zero needs some rough-usage-appearance, might as well wet-sand the hinomarus to make them look war weary. With 280 Grit sanded wet, I hit the meatballs and gave then a very tired look. Same with the tail numbers. And today, did the same with the meatballs on the bottom of the wing halves. I haven't painted the meatballs on the top of the wings yet.

I was trying to clean up the tail numbers on the rudder so I could repaint them. But, wet sanded thru the covering and just pulled it all off. Will recover. Also repainted the top of the wings. I got a new set of paint masks, so will repaint the tail numbers and Hinomarus. I'm looking at August completion now. Oh well, we fly till December most years!

What is your theory on the paint masks/paint problem?
Title: Re: Meister A6M3 Model 22 Zeke Build
Post by: Lane C. on May 31, 2019, 09:12:30 am
Hi Darrell, I first ran into the extra sticky paint masks on painting the PC-6 Porter. They pulled up the underpaint in several places. Before, on the P-51, Callie sent paint masks using a less sticky material and they worked well. I did pull some paint when removing one mask, but it was the tail number I had just painted, not the underpaint. I got in too big a hurry removing the mask. But, all in all the old material worked well.

On the Zero tail numbers, it also could have been that the underpaint on the rudder wasn't dry enough. But, I did try to make sure the overall paint on the fuselage was dry by putting it in the truck camper shell out in the Sun for several days. And, also used the Advatage 190 oil and grease remover before I applied the light grey paint over the advantage primer. So, I just feel the extra sticky paint masks are the main reason the paint pulled up.

However, I am aware it takes latex paint about 3 weeks to really dry. Maybe I should allow the repainted parts to dry that long before using any more paint masks.

If the weather settles down in June, I can be doing some flying while the paint dries. Got 3 planes that Barry has test flown, but not me. Ha
Title: Re: Meister A6M3 Model 22 Zeke Build
Post by: dlabby on May 31, 2019, 09:56:18 am
Thanks. All good info. I didn't realize Callie had more than one "stickiness". I got lucky on the Charger complicated masks, I guess. That paint was Randolph aircraft dope. Her mask edges were really good, too. I did a lot of experimenting on test piece that I built. Good luck.
Title: Re: Meister A6M3 Model 22 Zeke Build
Post by: Lane C. on May 31, 2019, 02:37:49 pm
Darrell, After I had the slight problem with the Porter, I ask Callie why the change. She said that several customers had complained the previous masks were not sticking down enough. So, she changed to the present. She can supply the old material as well on request.

I primered the rudder and several other areas on the fuselage today. Turned out to be a good day to paint.

Post by: Lane C. on June 01, 2019, 12:07:38 pm
Since I am basically done on the bottom of the wings, I added a few simple panel lines with 2B lead pencil. Then, clear coated them to keep them intact. Used Polycrylic Satin. Right out of the can - no thinning needed or "allowed." Instructions say NOT to thin.  Sprays nicely. Clear coated a few other parts as well.

Barry, yep, that worn out look is hard to do! Tested out some Green on the tail cone today. After it dried, wet sanded with 400 grit for effect. I can still revert to all grey at this point. Kinda like the idea of all grey with the markings. But, with the green on the upper fuselage and wing, it would look pretty cool. I need to make a final decision and get it painted. Summer's already rolling along!
Title: Re: Meister A6M3 Model 22 Zeke Build
Post by: Lane C. on June 13, 2019, 04:50:44 pm
Finally got to painting the wing tops Green. Took a while to mask off the wing bottoms. Then, painted the green on in about 6 very light coats in several directions. First coat was parallel to the chord, then 45 degrees to the chord both ways, then parallel to the span, then 2 more coats parallel to the chord. It still has a mottled appearance where the light grey can be seen and next i'll wet sand with 1000 grit to thin out the green to show some of the light grey in places. Hope this will make the green look crudely applied like the real deal.

Wet sanded the other wing to match. Winds are 20-25 today so that's a bit much to paint outside. I could crack the overhead door open and paint the meatballs, but not quite sure on that. I need the meatballs to be painted so I can add some panel lines and then clear coat.

Couldn't wait to get some wet sanding on the new markings. Made a new sanding block out of balsa and CA'd the paper to that. Works fine. As a word of warning, even 1000 grit cuts VERY FAST on new paint! Go slow until you get used to it.

I like to sand around new paint to keep it from looking like stick ons. In the process of sanding the Hinomaru edges, I found I could mimic the "white" around the meatball by sanding off the green. Wasn't expecting that. But that's how the full scale Zero looks. See last pic.

Rested a bit and then back to the shop to pull off the masking. I grabbed the cowl and laid it on the fuselage for grins. Several pics of the fuselage bottom. Tape pulled up some grey paint, but will sand those to look like wear marks. Also, will block sand the fuselage with wet 1000 grit. Still one more hurdle ahead and that's masking and painting the canopy. I always hate that as it takes forever! But, gotta be done.

Back to wet sanding! Used 1000 and 1500 grit. Took about 2 hours to sand the right side. Still have the markings to add. I sanded the rudder and elevator VERY LIGHTLY with 1500 grit. Didn't want to cut thru the Solar Tex.

Decided I had a bit too much sanding on the fuselage and repainted it. Will start over with less sanding. Seemed OK till I looked at the pics in the computer. Sometimes you can be too close to your work. Need to step back and take a longer view of things sometimes.

Used the airbrush with the same cross-hatch pattern as the first painting. Took a number of passes to build up the color, but the splotchy effect is still there.

Not a big deal since I didn't have any markings on the fuselage yet. Just the time lost going backwards.
Title: Re: Meister A6M3 Model 22 Zeke Build
Post by: Lane C. on June 20, 2019, 10:26:08 am
Kept the wet sanding to a minimum today. Less is More! I think it looks better with the wear below the cockpit area and just splotchy or mottled places. Next are the markings. Gotta finish the paint and get to finishing the build.

Then, using the model as a work base, started the masking. After masking, I used a jig from the P-51 build to use as a rest stand. Then began the air brush work. A few coats and then to dry overnight. Will clear coat on Monday.

I added some more silver wear marks to the cowl. Didn't really like how that looked, so began to wipe them off with some 190 solvent. And, in the process, those silver marks began to look good! So, I just started streaking them! I had a "happy accident" as Bob Ross used to say (Joy of Painting guy).

I think I'll quit while I'm ahead and clear coat what I have. It's easy to get carried away with the silver paint. The clear coat will make it look much better and match the sheen of the fuselage.

I was going to use the stand I made for the P-51 for the Zero. But, the cradles are a bit tight. I think I can open one end up for the Zero cowl and leave the other end for the P-51 cowl.

Also, my styrofoam work stand is getting a bit worn after several years of model building. I feel one end may burst when I put the engine in the Zero and allow the model to crash to the floor. So, I have added some 1/4 inch plywood on the ends for support. Should extend the life of the stand quite a few more years.

You missed it! Big day at Lane's Ranch! Barry and I put the Hell Bitch II thru her paces; weighed her, CG'd her, and photographed her. Then had a big fajita lunch!

Zero weighs 50.5 pounds WITH ballast!

CG is at 30 percent chord (7.6 inches aft of leading edge).

Span is 118 inches

Length about 7 feet

Steve, I would build an even BIGGER model, but I need a "Go Fund Me" account to buy that new trailer. Or bigger pickup like Barry's. I will leave it up to my viewing public to make that decision. Ha

Darrell, yes, lots of artist's depictions and a photo of Nishizawa's "105" in flight.

The "105" is white in the depictions but others have made it yellow. Based on the actual photo, that may be where the color confusion began. Colors are sometimes confused in B&W photos.

The last image is how I think it was with the yellow "105" off a plastic model box top.

Somehow the photos got messed up in order. Sonny said he had to reload something, so, I guess that's what put things out of order. But, the text is still correct.

Made a wing bag for the Zero. Nothing available commercially for a wing-half with 25 inch chord and 59 inches long. Used insulation material from Lowe's. It's a light double bubble with aluminum film covering. Edges were stapled together then wrapped with 3 inch Gorilla tape. This Gorilla Tape is Extra Glue, Extra Strength and is way stronger that any duct tape I have ever used. Cost of the material for 2 bags was $68. The roll of insulation was 4 feet by 25 feet and was just enough to make 2 bags. It's a matter of measure TWICE and CUT ONCE as too short in width or length will render the bag useless. Remember to leave excess on either side of the wing and lengthwise as you need to allow the bag to "balloon" open to be able to insert the wing without damaging the wing parts such as control horns and linkages. Once the Gorilla tape is down, it's not coming up! So, draw some guidelines on the material to help keep the tape straight the first time you lay it down. The bag is very similar to the wing bags that came with the CARF P-51. Bag only took a few hours to make.

I finished the 2nd wing bag today. Glad that's done. I picked up some rattle can green for the instrument panel and will concentrate on getting that decaled and in the plane. I included a photo of the CAF Model 22 Zero instrument panel to show the similar color of the panel. The model panel will take on a darker tone with all the black instruments and guns. I need to find a gunsight.

Looking good. Can't wait to see that bird fly. Should be awesome.

I was looking at the gun placement and realized that the guns are right in the cockpit and it looks like there's no isolation from the pilot. The noise and fumes must have been hell when they were fired.

Steve, I think the pilots got high off the gunsmoke and gases! I've thought about the same thing, but many WWI biplanes had the same arrangement, but open cockpits. Wouldn't be as loud, but not exactly quiet!

There's always a loose end lying about. I want to add some stitching to the wing bags to really make them strong. Used a handy stitcher and some heavy waxed thread. Works well, but time consuming.

The location of the zero fuselage mounted guns was not unique. In fact, the Douglas SBD Dauntless had its forward-facing guns in precisely the same position. The biggest difference between the two installations was the caliber of the machine guns, the SBD's was larger. The SBD was well liked by its pilots so I doubt that they or the zero pilots were gassed when they fired their guns. Below are links to photos showing the zero cockpit layout, the SBD layout and the Curtiss P36 layout.

Herb, with the later versions of the Zero, Model 52b and on, the cockpit guns were 1 - 30 caliber (actual 7.7 mm) and 1 - 50 caliber (actual 13mm). I am sure they had at least some provision for venting the smoke and gasses out of the cockpit. Whatever the situation in the cockpit when firing the guns, it wasn't much of a bother as the Zeros cleaned house early on! Nishizawa got 82 kills officially and perhaps more unofficially. Lane

A little known factoid about the Zero. The Zero used an aluminum alloy stronger than the alloy used by the US. Below is a portion of an article on the Zero.

" Most of the aircraft was built of a new top-secret aluminum alloy developed by Sumitomo Metal Industries in 1936. Called "extra super duralumin" (ESD), it was lighter, stronger and more ductile than other alloys (e.g. 24S alloy) used at the time, but was prone to corrosive attack, which made it brittle.[10] This detrimental effect was countered with an anti-corrosion coating applied after fabrication." 

This aided in the design of a very light fighter with extraordinary range.

Post by: Lane C. on August 09, 2019, 11:39:00 am
Herb, that's an interesting item on the Top Secret aluminum. Didn't know that. But, that anti-corrosion solution was the Aotake coatings which were similar to Zinc Chromate the US used.

http://colesaircraft.blogspot.com/2014/01/japanese-wwii-aircraft-aotake-primer.html

And, the longest range Zero was the Model 22 which had an additional 12 gallon gas tank in each wing. The Model 22 was essentially, a Model 21 with some updates such as downdraft carb which changed the cowl shape, making Model 22's easily distinguishable from Model 21's. It still kept the long wing of the Model 21's vs the later Model 52's which went with the shorter wing. Lane

Actually, after some thought, the short wing Zero was first used on the Model 32, but that plane was sort of a dud. Basically, they just removed the folding wing tips on the 32 and put squared/blunt tips on there. The Model 52's had a more ascetically pleasing rounded appearance on the wing tips (same shape as the folding wing tips). The 52's retained the additional 12 gallon wing tanks, but the Model 22 still had better range.

Moved the Zero inside to temp controlled air. Might be a while before time to fly.

Zero wing bags next to a CARF P-51 wing bag. Kinda dwarfs it.

I'm basing it on my own experience with a .30 cal machine gun from a helicopter, a .222/3 gatling gun from an AC-47 and the 20 mm from the AC-130. Loud and lots of gas.

Since it's going to be Oct before i get the Zero out to the field to run the engine and all, I decided to make a run stand to run the engine at home. I can do this under the carport in front of the work shop. Hasn't required much lumber: 1-2x4, 1-1x4, and some scrap 3/4 inch plywood. Will clamp or screw to the work table. I laminated 2 pieces of the 3/4 plywood to make it extra strong. Will make a shelf at mid level behind the engine mounting plate for the gas tank, battery, and etc, to run the engine. It should handle the DA-100 fine.

Mounted the engine to the mounting plate. Built a shelf to hold the gas tank and other stuff. Added an aluminum bib to keep all the exhaust splatter off things. Getting close to finishing. Will be able to run the engine soon.

I finished the stand today. I made it to be controlled by the Tx since that's the easiest way to control the whole thing from starting to shut down. one servo for the throttle. The choke can be moved by hand when propping. Should run fine right off the bat. But, with two-stroke gas engines, you never know.

 ran the DA-100 on the new run stand yesterday. All went smoothly. Once I got some gas to the carb, she started up and ran nicely. I made a video of the first run and it's linked here. It's 16 minutes long, but you can zip thru it if you like. I attempted to edit it down to knock a few minutes off in my  computer program, but gave up. Just another ap to live thru the learning curve. So, I posted the whole video to Vimeo. I listed the vitals on notebook paper during the run so you can get an idea of what's going on.

https://vimeo.com/356517706 (https://vimeo.com/356517706)

I made the first run just the way the carb was adjusted from the factory. It wasn't any too rich, but wasn't lean either. On the two runs after the initial fire-up, I opened both needle valves about one half turn. That made it messy rich. But that's OK on a brand new engine. I ran one half gallon of gas thru it on this first outing. Going to run a couple more gallons at least, and maybe more, before I reinstall it on the Zero.

A few still pics of the engine running and the "bib" catching the exhaust residue. The heavy residue is after I opened up the needle valves. First run was pretty clean.

You can see how the silver prop almost turns invisible when running. I am going to make a safety shroud to put over the stand to remind me where the prop is! I'll post some pics when I complete that detail.

Post by: Lane C. on August 29, 2019, 05:12:11 pm
Running the engine with the silver prop was kinda dangerous because the prop almost became invisible. I'm making a shroud to at least give an indication of there the prop is when running. Going to paint it bright red and yellow on opposite corners.

I'm continuing to run the DA-100 and I've burned 1.5 gallons of gas in it so far. I have it running right at 6600 max RPM. Still needs a couple more gallons of gas run thru it. I have also installed the large Zero spinner which may take a few RPM's off the total high end number. But, it's still getting broken in. I would fly it at this point as it's pulling enough RPM's to fly the Zero. But, will go ahead and keep it on the run stand a bit longer. Still hot so no real hurry.

I am going to run Red Line oil in it at this point as I'm out of the gas mix I've had on hand. Desert Aircraft runs/recommends 40:1 mixture which is a bit less oil than I've been running all these years. May try that ratio now, or something close. 3 ounces per gallon of gas would be about 42.5:1. But 3 ounces is easy to measure and easy to remember. Ha

No pics of the plane or engine this post, so that is a rarity. I must be having heat stroke.

Post by: Lane C. on September 05, 2019, 01:48:52 pm
Ran again today and hit 6705 RPM! That's 7 quarts of gas thru it. I'll keep going until I have burned  about 4 gallons. It should be well broken in by then.

I mixed the Red Line oil in 2 gallons of gas and not sure the difference. Engine ran faster, I can say that. The mixing instructions say for 50:1, use 3 ounces per gallon, which is a bit more oil than other mixing sources. But, drops to 8 ounces for 3 gallons. That's 2.6 ounces per gallon. Anyway, I mixed it straight 6 ounces per 2 gallons.

Post by: Lane C. on September 07, 2019, 10:51:33 pm
I ran the final break-in run today. I decided that 3 gallons gas is enough break-in. Time running was 10 hours. I had it set so lean, the last 2 (quart) runs took 1 hour and 15 minutes each! Now I can bring the Zero back out to the shop and plug the engine back into the model. Won't be long till the temps come down the scale a bit.

Post by: Lane C. on September 12, 2019, 10:23:47 pm
I put the DA-100 back on the Zero and completed a few other details today. The 12 Channel Rx is supposed to have the two antenna "whiskers" at 90 degrees to each other, so cut some plastic sleeves and glued them to the plywood. On the 3 satellite antennas, one should be at 45 degrees to the other 2 to create another plane for receiving Tx signals. Made a little holder out of plywood and velcro'd it to the floor bottom. And, Desert Aircraft says the carb should have 2 inches clearance off the cowl, so cut a hole for air flow to the carb. Lastly, painted the "opening" for the oil cooler black. She's basically ready and waiting to go to the field.

If I had Barry's truck, I'd bring both the Zero and UV-20A to the Big Bird meet on Sat. But, am only bringing the UV-20A to fly with the new landing gear I made for her.
