Title: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on June 15, 2018, 10:39:40 am
Due to a problem with the Zero parts kit, I am putting that build off to the back burner for a while. Instead,  I am working on The World Models Pilatus Porter PC-6 kit from Airborne-Models. They have a giant 116 inch Stearman ARF that interested me, but they had already sold out of that one. But, I have been looking at the PC-6 for a good while. It will run a DLE-85 engine. Should be a fun plane for all around flying, especially when the winds aren't warbird perfect. The PC-6 is well known for a bush plane and for carrying sky divers up and getting back to the runway before they do. Quite a few good videos of the Porter, both RC and full scale are on YouTube.

The kit is amazingly well prepared and it might be called and ARF Kit. Many things are laminated for you and all parts are marked either with the laser or ink stamps. Kit is well packaged and comes in two boxes. Nice glass cowl and scale landing gear included. Covering is not included. But, they offer the same model in an ARF with red and white color scheme. In fact, being a snap-together concept, you don't build this in a set of plans, you just make sure your table is flat and use 90 degree triangles or squares to set the parts correctly. Most of the gluing is CA with a little bit of slow cure Epoxy. Goes together fast. Even the sheeting is pre-joined and cut to fit with minimal cutting. A set of scale drawings is included for reference along with an instruction manual for the kit and ARF version. The aft fuselage is designed to be removed for transport if needed (fuselage is over 7 feet long). All the controls for the elevators and rudder are directly servo controlled, so all this is required is to connect the servo cords upon assembly at the field and bolt the aft end on to the forward fuselage. A few pics to bring you up to speed on the build so far. Note the preassembled parts. Both fuselage sides are pre-sheeted and many formers have laminations pre-glued on them. All parts have fit like a tailored-suit so far. A well engineered kit. The only potential problem is being sure the formers are facing the correct direction (fore/aft) as the instructions do not make this clear, especially the photos.

Keep going and the job gets done! More sheeting, the bottom of the forward fuselage. This went better than the previous sheetings. Added a few more parts and pieces.

Sheeted the top of the fuselage and that went pretty well. Next, the engine box needed some attention before I glued it in place. So, I assembled the DLE-85 with the vibration isolation mount. Got the engine mounted on the box and then fitted the cowl. Still need to attach the muffler and open up the cowl. That cowl is LONG long long! I am going to make some changes on the gas tank install per the booklet and scale drawing. The gas tank sits way too far aft for my likes. But, getting access to the tank with the whole forward top end (under the cowl) sheeted will be difficult so I will only partially sheet it to give clear viewing access to that area with the cowl off. And, will run at least a 32 ounce tank of some description.

Darn it, you keep coming up with the neatest kits. When I'm hunting again, I'm going to put you on it. Pictures look great. Is this your plane? What livery are you going after?
Getting ready to head over to Tim L. to see if we can fit 2 big planes in his Ford; then off to Muncie Wed am.

Hi Darrell. Yep, planes keep coming out of the woodworks! I have been interested in a Porter for a while, but VQ wanted shipping AND taxes! Yikes. But this one is quite a bit larger - and a kit. This one is for me, no outside build. Good luck at The NATS. Lane

Oh, and paint scheme. I was interested in a silver base with more color on top of that. But, today I saw a 1981 US Army paint scheme that's good looking. Green on bottom, white on top and yellow strip in the middle.

Took the day off from House Paint Prep to stay out of the heat. Worked on the engine box some more. Cut a 2.5 inch hole behind the carb for fresh air and access to the throttle and choke linkages. Also, added some tri-stock to the inside of the box to better support the DLE-85 power. Made a sliding plywood tray for the gas tank as once the forward fuselage is sheeted over, you cannot get to the tank. So, it will be able to slide in thru the door, turn, go forward up to the engine box, and then all the way forward. Held in place with a screw in each end to keep the CG from moving (if the tray moved aft). I'll use a Dubro 32 OZ tank for the final deal. Even though 32 OZ could go quickly in an 85cc engine, I won't be flying flat out all the time like Barry in his Zero!
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on June 23, 2018, 07:21:54 am
Added a steel clip on the aft end of the tray to keep it down and 3 screw holes on the forward end. Gave the engine box and tray a coat of Z-Poxy to seal it for gas drips. Still need to order a 32 OZ tank, but the Dubro 24 OZ tank is pretty close to the same size. Need to hook up the throttle and choke servos before I sheet all the front end.

Overall high shot of the engine box.

Post by: Lane C. on June 23, 2018, 08:37:31 pm
Got to the throttle and choke servos today. Plenty of room to run them and linkages alongside the gas tank.

Even with the 32oz tank?
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on June 24, 2018, 08:39:06 am
Yes, the 32OZ tank is only about 3/4 inch wider. Tank can sit aft quite a bit too and the rods get wider apart to the rear. If the Dubro tank does not fit, I can go with another Fiji 1 liter water bottle tank - it's long and skinny.

Made a cover for the engine box to give strength and provide access to the inside for routing the fuel lines etc. Made standoffs for the 4-40 rods since they are so long to keep from kinking.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on June 27, 2018, 05:47:25 pm
Well, turns out the Dubro 32 OZ tank is a wee bit fat, so, going with the clear 32OZ tank. This is the Red Wing version, but I might get the kit and use the Fiji water bottle version as it's not subject to parts falling off inside the tank. But, as far as fit, they are both about the same.

Sheeted today. Then some light sanding.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on June 30, 2018, 09:20:09 am
Last night, glued the final plywood plates on the fore and aft fuselage sections. I think they added these plywood parts for more strength. Let that setup over night and this morning got to fitting them together. Not a whole lot of work there, but needed some sanding here and there to get them to fit together flat. Got the fore and aft sections fitted and screwed down. Whole model is almost 8 feet! Sanded down the plywood joints even with the sheeting. Still some 60 grit sanding to go. Going to have to decide how to finish off the bird - Solar-Tex, Sig Koverall, glassing, or ?. Got time to think it over while I build the wing and tails.

Moving the fuselage inside to make room for the wing and tail builds. A few shots of the fuselage in the truck and inside next to the other models.

Post by: Lane C. on July 01, 2018, 04:50:15 pm
With the fuselage out of the way, I moved to building the vertical stab. Went pretty quickly with no real problems. Kit is very well designed and laser cut. Got the stab roughed out and glued up. Front of stab and rudder is next.

I have a small 47inch wingspan Pilatus Poreter PC-6 ...flies great and the barn door flaps do provide weird STOL characteristics.

I think the completely squared off vertical stabilizer is strange and Iconic for the airframe...which seems more like a box in some regards.

Moved to the horizontal tail. Started to get twisted with me, so took a long time to get it straight. But, got it all glued out and looking good. Also built one elevator and mocked it up on the fuselage.

Been painting my house, so, no work on the Porter till now. The wing half is pretty big, so I have just put the pieces in place without glue to begin with to see how it was all going to fit together. Looked OK so I started gluing as I went. I want to make sure it's as straight as possible before sheeting.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 14, 2018, 08:06:39 am
Got the bottom sheeted.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 14, 2018, 01:47:21 pm
Got the top leading edge sheeted. Takes a while to do the whole top side since I have to use Yellow Carpenter's glue and allow dry time. I need more clamps! Clamps get weak over time and fall apart.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 15, 2018, 07:00:49 am
Finished the top sheeting. Bit of rough sanding done. Flap and aileron build next.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 16, 2018, 11:39:42 pm
Flaps are the order of the day! Built both sides as it's easier to get them right that way. Added 50 pounds of weights to keep them flat while drying. But, they look good on the wing.

That plane has some awesome flaps.

I always like the bare bones look. On my planes I sand and fit everything to 0.001 of an inch tolerance. Somehow, when I'm done with the covering and paint, my tolerance opens up to 0.250 of an inch. I have no idea how or why that happens.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 18, 2018, 10:34:26 pm
Steve, don't sand! Haha. Got the last aileron built today and started on the right wing. Same as the left, except mirror image. Had to correct a warped part or two before I need them. Clamped the trailing edge to a large aluminum angle stock and heated it up. Will check on it in the morning. This method worked on parts for the left wing. It was very hot out here today - 108 Deg F on the front porch in the later afternoon. Porch is on the East side too.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 19, 2018, 09:08:21 pm
Did a bit more on the wing layout today. It was 112 Deg F on the porch today. So hot, it only got to the mid  80's in the shop with the A/C on all day. Just laying out the ribs to make sure I have them in the correct order. Since the booklet only covers the Left wing, you must remember to reverse all the parts for the Right wing. Dry fitting. So far, the right wing appears to be going better than the Left one. Left one started out on the wrong foot. Ha.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 21, 2018, 08:47:58 pm
Got the Right wing going pretty good. Better than the Left wing for sure. Guess I just got off on the wrong foot with the Left wing. Almost all sheeted now, but letting the yellow glue on top sheeting dry overnight. Steve, more bare bones for ya.

I've decided the wheels are too small in diameter. Probably need to go to 6 inchers. Barely any prop clearance. Besides, this plane is a STOL aircraft and needs rough field balloon tires. Not sure I can find the exact wheels.

I have 4" wheels on my little 6' wingspan plane, you need at least 8", maybe some wheelbarrow tires would work.

Got to the glass work today. Filled some low areas and sanded  the entire fuselage. Going to glass the fuselage and Koverall the wings. I use Z-Poxy and 3/4 Ounce glass cloth. Works well.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 28, 2018, 05:52:17 am
Moved to the nose of the fuselage with one coat of Z-Poxy on the glass. Also sanded the first coat of Poxy on the top fuselage and gave it another coat. 2nd coat of Z-Poxy really shines out! It will get one more sanding before primer.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 28, 2018, 01:53:36 pm
On to the left and right fuselage sides. Going pretty smoothly. Really eats up the Z-Poxy on a model this large. Got some more ordered though. Apply the Z-Poxy over the cloth, wait 2 hours, then trim off the excess glass cloth, and sand lightly. Pretty much the process. Oh, forgot to mention, I use playing cards to squeegee off the resin after applying it with a small paint brush. You can even pour the resin onto the cloth if you like. But the brush can push the resin down into the cloth so it will help hold it down until you can use the playing card to evenly spread it over the cloth. Once you have it saturated with resin, you can go back over the cloth with the card several times to remove excess resin and make sure the cloth is solidly down on the balsa. Don't worry about the rough edges of the cloth as they will largely vanish after the resin is on the cloth. They can be sanded out later. No biggie. Also, you will have several coats of grey primer over the glass job, sanded in between coats, to even out any low spots, then the paint. Glass work isn't rocket science for sure, just appears to be difficult. It does require a light touch and some patience, however. You cannot get too horsey with the wet cloth as it wants to distort with too much pressure when using the brush or playing card on it. Just make long, even, light, strokes. Ha
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 28, 2018, 07:13:18 pm
Pretty much done with the forward Fuselage section and wanted to see how all that sanding on the top turned out. Best way is to spray some sandable primer on it. It looks OK for now but will use some Advantage high build grey primer to fill in a bit more of the small waves. Not too noticeable in the pics. The aft fuselage section is up next for glassing. Won't be as tough as the larger forward section - I hope.

Post by: Lane C. on July 29, 2018, 02:23:42 pm
Thanks Darrell, It's a BIG project for sure. Glassing and covering is one thing, but painting is another BIG project in itself. Since I am about out of Z-Poxy, I needed to put the Pitts muffler on and cut the cowl to fit that. Due to the design of the cowl and how it comes to a sharp point, I had to cut the cowl a bit more than I would like to get it on and off. But, some of that goes with having an 85cc engine! Maybe should have used a DLE-55 rear exhaust. Ha

Just no getting past how the Pitts Muffler sticks out on the left side. I don't agonize too much on such things as it is, after all, a MODEL AIRCRAFT! No one will notice that going by at 80MPH! Haha
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on July 30, 2018, 06:03:30 pm
Plugging away at small details. The cowl needed the exhaust stubs glued on so did that today. OI sanded off the gel coat down to bare glass and then used thick CA to glue them to the cowl. After that, used some Advantage grey primer in the rattle can on the stubs.

Steve, in actuality, that's a circle template, large circle template, but due to perspective, it appears as an oval. Ha. I do have an oval or ellipse template, however. I use the templates all the time. You should see the large French Curve I made out in the Template Shop one day when things were slow! As well as a set of large radius gauges. No end to the fun we had out there. Kinda miss those early 80's days!

Post by: Lane C. on July 31, 2018, 06:26:51 pm
Went ahead and used the remaining Z-Poxy to see if i could glass the entire aft fuselage section. Looks like I will just make it. But, have some more coming for the tail planes. This is kinda boring work, mix the Poxy, spread it on the glass cloth, wait 2 hours, come back and trim off the excess glass ends around the fuselage features and do it all again. Got 3 sides done so far, and will do the last one tomorrow. I usually have some Z-Poxy left over after each application so I use it on the forward fuselage as a 2nd coating rather than just toss it out.

I found a cheap $15 pilot. He'll do fine as a Porter pilot. He's really a 1/4 scale pilot, and the Porter is 1/5 scale, but better too big than too small. I scrunched him down a bit in the pics. Need to make a simple support under him to pull some g's and hold him up. Pulled out the windshield to look at that while I am at it. Needs trimming. Gotta be careful on this since no spare parts are available. He needs a headset and mic. Anyone got a spare set? Maybe even a ball cap.

Got the aft fuselage glassed and sanded down a bit. Then shot some red primer on top to see how she looked. Not too bad. I see a little radiiused corner that needs some build up with Dolphin Glaze. Got that starved horse look I saw up front. Hate to fix that because it takes 3 coats of bondo, but the top gets all the attention. Especially being all white upper fuselage.

You might consider making a plaster is Paris mold before you cut the canopy.  Then you could have a new canopy pulled if something happens.  Sparky has pulled some pretty large canopies for me.
Shame that the newer kits are not supported.  Looking great.

Hey Max, good idea on the spare canopy. Jack Haynes has the ARF version of this one and said his canopy was kinda delicate when he trimmed it. Good to have a spare.

I was in Detroit back in the 60's and applied for a job as a draftsman. I had my little plastic templates and triangles in a briefcase. They showed me the drafting machine I would be using, it was able to move all over a 20' x 40' wall, the french curves were over 10 feet long. They were designing truck cabs and dashboards and needed full sized drawings. There were almost no straight lines anywhere. I didn't want to work there at all.

Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on August 03, 2018, 03:05:36 pm
Darrell, I think it's just some Rustoleum red primer. Grey primer would be better, but I used up the last of what I had. I'm going to go over the red with grey Advantage primer from English Color when I get the paint gun out and ready to primer it all. It sands down really easy.

Got to the starved horse spot on the left fuselage. Masked it off and laid down some Dolphin Glaze putty and then leveled that first coat off a bit. Next, masked it off again and laid down another coat. Same thing, leveled it off and then sanded and gave a shot of red primer. Looks better. Also, got a gap where the two sections come together.

It's not that bad! Using that aluminum file really cuts that Dolphin Glaze down fast. Not that much sanding left to do. Those radiused corners would really look bad once they are painted white. That joint between the two sections will show itself also, but not sure what I can do about that. I always say, it cannot be seen going by at 80 MPH! haha. Now, putting individual RIVETS on all surfaces of the plane IS BEING A PERFECTIONIST. To me, an absolute waste of time. That's only for showing off in the pitts! haha

Back when I was in high school shop class, around 1957 or so, I remember my shop teacher telling me to get Garnett paper to sand the Cherry wood end table project I was building.

He was right, sanding Cherry was like sanding Oak, I bought a five pack of the 8"x10" sheets, it was expensive compared to the regular sandpaper, but it was really worth it. I've built hundreds of planes over the years and that stuff really holds up.

I've only got one sheet left, if I do any more serious building, I may need to buy another pack.

Moved to the horiz stab today. Got the glass cloth laid out so I could cut strips off for the stab top and bottom. You can lay it out on the work table, but the table needs to be VERY clear of any rough spots or snags. The cloth is pretty flimsy so you need to clean off the table thorougly of any trash or whatever. Lay it out and use an OLFA cutting wheel you buy at the sewing shops. Not expensive and lasts a fairly long time. But it's the ONLY way to cut the cloth without tearing it to pieces. After cutting, I laid the first strip on the stab and poured some Z-Poxy on the cloth. With a regular playing card, I begin to carefully pull the resin over the cloth taking care not to put too much pressure on the cloth or it will be distorted. After a number of pours and passes with the card, the resin is evenly distributed over the stab and cloth and it looks pretty good. Takes about 2 hours to fully setup. While I was waiting on the stab to dry, I added a piece of glass cloth on the top of the rudder. Takes a while to do all the surfaces, but that's the way glassing goes - a little at a time. One last piece to do under the rudder counterbalance/offset and it's done. Next - to glass the elevators.

I really should have remembered to thin the Z-Poxy with Butyrate thinner on the first coat of glassing. It makes the resin penetrate better and is much easier to spread around with the playing card. It does take a while longer to dry, but that is about the only negative. Second coats may or may not be required, but if you do make one, thinning it again provides a very even and flat finish that requires little sanding.

Glassed the elevators today. Just about done with glassing. Finished rudder as well. Next will move to covering the wings with Sig Coverall.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on August 13, 2018, 06:16:29 am
Getting done with the glassing. Added the fences to the horizontal tail and gave them a coating of Z-Poxy to seal them up. Sanded down the cowl to remove the gloss paint in prep for the grey primer. Will start the wing covering with Sig Coverall next.

I'm not exactly sure why they added the fences on the H tail. It appears that they are there to keep the elevator counter-balances "clean," but that's just a guess. Fences are usually on the wings.

I've been spending a fair amount of time looking for photos of the top and bottom of the wing. I want to see how the US ARMY markings are used. Finally found a plastic model of the Porter to go by. Plastic Modelers are usually very accurate on their markings. Photo shows how the top and bottom wing is marked. The opposite wing half gets the Star and Bar. Cassie Graphics should be able to make these paint masks easily.

Now to wing covering. Had a low spot on the left wing where the trailing edge and flap meet. Filled it with Dolphin Glaze. Then, sanded all the wing parts with a foam sander and gave them 3 coats of Nitrate dope thinned 2.5 to 1. Sanded them in between coats. Dried very fast. Now, to get the Sig Coverall cut and prime the wood with Sig Stick It. Been a while since I used Coverall. Will start with a flap or aileron.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on August 15, 2018, 06:51:35 pm
Kept at it this afternoon. Covered one flap with Koverall. Then laid on 2 coats of Nitrate out of the can with a brush. Probably should be thinning that out as well. Went OK. Koverall is a LOT easier to handle than the glass cloth. Glass cloth gets snags and runs like crazy. Koverall is actually pretty tough stuff. It's very close to full scale aircraft covering, I would bet. I pulled out the cutting mats and bumped them together for the Koverall.

I completed another flap and aileron today with Coverall. Got one more aileron to do tomorrow. Then the left and right wing halves. Kinda getting interested in doing the paint job. Covering is going OK now that I am back in the hang of it. I shot some grey primer on the first flap I did yesterday to see what it looked like painted. Needs a few more coats of primer to even it out, with sanding.

Post by: Lane C. on August 20, 2018, 07:14:06 am
Hi Steve, thanks. I haven't used Koverall in a long while. I was worried that the Koverall would be in small sheets and have to piece it together on both the top and bottom wing half. Haha. The LARGE package is a single sheet that's 5 yards (15 feet) by 60 inches wide! I could do several Porter wings and fuselages and still have plenty left over. This is the first time I've used Stix-it too. Last time I think I used the Butyrate dope method to glue it on. Not as easy as Stix-It. One more wing half to cover and then it's on to priming and painting. Also on the Stix-It, I am sure it's the same adhesive as Monokote and other iron ons as it smells the same when I heat it up. Kinda pricey, but one 8 OZ can goes a long way.

Post by: Lane C. on August 21, 2018, 04:34:51 pm
Had to take a few steps backward and fix a boo boo. I added a plywood gusset to a wing rib because I pushed the aluminum wing tube in too far and it cracked a rib. Patched it up fine, but forgot to recut the access hole in the rib for the aileron servo wires back to the fuselage! Crap! Had no choice but to cut the Koverall, fix the goof, and recover. Stuff happens! But, almost through with both wings and can move on to priming tomorrow. Also, just about to finish gluing the flap and aileron on the left wing. Last photo is the finished right wing, ready to prime and paint.

I need to talk to you some time about Koverall and Stix-it. But for now: Did you try to find any Solartex? Koverall feels kinda clothy--has texture? Koverall has no adhesive of it's own. Do you heat it after gluing on to stretch it? will primer be enough to fill in clothy holes? Just wandering all this cause I'm considering a biplane build this winter.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on August 22, 2018, 12:21:03 pm
Hi Darrell, my post today may answer some of your questions about primer. This morning I shot 3 coats on the wings and sanded in between coats. Before covering, you need a couple of coats of Nitrate Dope sprayed on to seal the balsa for the glue. The Koverall then needs a glue applied to the balsa with a small brush. Stix-It works well. Once you glue the covering on, then you heat it to shrink. It's almost like a fabric iron on such as Solar-Tex. And after it's on the model, then you brush on 2 coats of Nitrate Dope to seal it. Then you can prime it and paint over that. The 3 coats I laid down look pretty good, but I could keep going to make it look like an auto finish with more and more primer coats. Solar-Tex is sold out of the Natural linen color and almost every other color as well. So, until Ora-Tex can gen-up with their close-copy, there won't be any good fabric coverings, that I know about anyway. I use the Advantage 301 high build grey primer. Lee Rice and Jack Haynes use this primer also. As far as feel of the Koverall, it is about as close to genuine fabric aircraft covering as you can get.

I hit it hard today and spent 7 hours painting. Got the white on the top and bottoms of the wings. Outboard bottom gets white and the rest OD Green. Three coats over the grey to make it look white.

They are a BIG consumer of time and I am trying to get the Porter painted! Besides, you cannot see them when the plane is going by at 80 MPH. Same thing for rivets! Ha

I will add that I use Green Frog 1 inch tape for edge lines on paint jobs. Always had good luck with it.

Sanded the white lightly and put some more coats on with the new can of white. Painted the seats a shade of green since this is an Army bird.

Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Steve Rogers on August 29, 2018, 03:18:16 pm
Back when I was doing scratch building, I used to make a engine mock up to make it easy to locate the mounting holes for the engine.

It was just a 1/8" plywood back that had the the engine mount bolt pattern. I had a dowel that was equal to the engine length glued to the plywood at the center of the crankcase position. The dowel had another removable dowel in the center of it that was the size of the prop shaft. You can also make a 1/8" ply circle equal to the diameter of the spinner to check clearances for that too.

The mock up was easy to move around to find where the engine mounting holes would hit on the firewall when the prop shaft was centered in the cowl, removing the prop shaft dowel was sometimes needed to make it easier. It was also very easy to mark the location of the engine mount bolt holes.

I tossed my DLE-35 mockup, during my latest shop cleanup, when I decided that by scratch building days were over.

If the description above is too confusing, I can slap one together and take a picture of it if needed.

I'll trade RAIN for flying any day!  But, kept going on the painting today, mostly clear coating. At least, I can handle the white parts now without grinding in the dirt. Even got her on the main gear just a while ago. On the last photo, you can just see the low sheen on the rudder/vertical tail assembly. That's Matte Polycryllic. I am using tghe 6 inch wheels I bought for the large Zero since I am not close to needing them for the Zeke. More ground clearance and aluminum wheels for the heavier model. Plastic hub wheels on 40 pound planes is not a great idea. I had to make brass tubing adapters for the smaller diameter axles to match the 1/4' shaft holes on the wheels. Just put them on there and filled them with hot solder. Works fine. I need the tailwheel mounted next. Unless I remember something that needs to go on before that. Ha.

Got the spinner drilled for the DLE-85 and mounted it with a Xoar 23x10 prop! Good ground clearance. Got the pilot installed with a seatbelt made of Velcro. Began working the windscreen. Little items like the transparency take a lot of time.

Looking like it's almost ready for air under its wings. She will be a good everyday flyer for any wind conditions under 30 mph. Ha. Good work and in a timely fashion for Steve. Ha

Yep, Barry, looking forward to getting some air under her wings! Won't be long.

Got the vertical stab and rudder glued on today. Also rigged the tailwheel steering after that.

I taped off around the glue joint so as to make a retainer for the fillet. There was a small gap along the front of the vertical stab and needed some extra epoxy. I laid down a second run of thick epoxy to make a glue fillet. I guess the horizontal gets glued on next. Got to make sure I get it level with the fuselage and sitting at the right incidence.

I thought you needed to make the horizontal removable so it would fit in your truck.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on September 09, 2018, 08:14:11 pm
Steve, Nope, the entire tail end comes off from about the mid fuselage aft. Of course, would have been nice to be able to take the horz tail off, but just not strong enough that way. It would likely come apart on the first flight without being epoxied. I just wanted to see how it would fit anyway.

Got the horz tail epoxied on today. Took some shimming to get level. Then laid on lots of 30 minute epoxy. Seems pretty solid once glued on. Also installed the factory supplied hardware for the servo linkage. Very robust so used it vs my own hardware. Getting close to finishing the build. Going to make a stand to bolt onto the aft fuselage when the tail end is taken off for transport. I've got an idea to try out.  Also will need  a stand or platform for the empenage to ride on too. Build doesn't end with just the airframe! Always more details to figure out.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Steve Rogers on September 10, 2018, 07:54:46 am
The reason I'm confused is because I thought you were also going to epoxy the fuselage together so it couldn't come apart.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on September 10, 2018, 08:44:24 am
No, just the opposite. The fuselage is not likely to come apart at the middle as there is not the stress that there is at the horizontal tail. Ideally, I would have liked to take the horz tail off to transport, but the small surface area where it attaches makes it difficult to make a secure joint with just two bolts.

This is one awesome plane! What a tailwheel assembly. Whew. You are so right--lot of ancilliary stuff that goes with a build like this. Building jigs, transport, etc.
Driveway full assembly pictures will be coming soon, I'm sure.

Got the stand made for the front half of the fuselage. simple construction of scrap plywood. Used 6-32 bolts and Tee-Nuts to attach to the former. Requires weights to hold the back end down due to the large engine. Going to make the stand for the aft fuselage next.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on September 10, 2018, 06:20:29 pm
Still at it! Got the stand for the aft fuselage finished this afternoon. Just 12 x 18 plywood and 5 pounds barbell weights. Sits flat on truck bed. And hope it doesn't tip over.

Time for a CG test today! Made a rig to hang from the ceiling. Worked OK, but a block and tackle would have been easier to hoist with. Weighted 34 - 35 pounds. CG was 31 percent MAC with 1 pound lead on the nose. Should fly nicely this way. Darrell and his brother Darrel are pilot and co-pilot. They've not had much work since the Bob Newhart show back in the 80's. But, seems they were happy to get a gig. Got some servos on order from Tower. Used old ones for the CG test. Once I get the servos installed I will be almost ready to run the engine. Getting close to the maiden voyage!

Did a couple of small details while waiting on servos and batteries. Painted the pilot's hair! Ha. Looks a bit more believable. Also painted the turbo exhaust stubs.

Post by: Lane C. on September 16, 2018, 09:03:47 pm
Got the three LiFe batteries mounted today. Needed some ballast up front, so, these weighed 1 pound together, and that was about what I was going to add with lead weights. Power switches on the right side of the fuselage. Debated on hiding them in the cabin, but, spent lots of time on building the bird, so, mounted them outside. They will be easy to get to for sure.

Took the lady outside to get a few pics in the sunlight. Also installed the fuel dot in front of the cockpit.  Did another CG test and the servos mounted in the wings moved the CG aft a bit from the first CG test. No big deal, just add another 8 ounces to the nose. Getting close to engine run time!

Got the plastic window inserts glued in. Also put the stick-on instrument panel in place. Also got my Hobby Pak wing bag today. Very nice like several others from Hobby Pak. Still need to tape down the windscreen. Not much left to do but wait for it to stop raining.

Always looking for a few details I overlooked. I Noticed the wheels on the full scale UV-20A were painted white on the outside and black on the back side. So, decided to fix that today. Took the wheels apart, primed and painted them. Then baked in the oven for 2.5 hours to set the paint. Not a good day for painting. But lucky the wheels are solid aluminum so they could take some heat. Also outlined the pilot's access doors but no photos yet.

I need to build one more part of the transport supports. I need a wheel chock for the main gear to make sure the fuselage doesn't roll around on the long drive. The back end will be supported by a stand that may not take much forward/aft movement without damaging the fuselage. With all the rain, got plenty of time to make that.

Post by: Lane C. on September 24, 2018, 11:18:07 am
Made the wheel chock out of scrap plywood. Also did some felt tip marker work on door panels. I'm ready to take to the field! Just need some Sun shine and dry field.

I'll put it online here if I come out, but lately it's hard to know what the rain's doing. Forecast keeps changing. I hope to get it flown a few times before Oct 13. But, can't say for sure. May have to put it on static display only for the 13th. But, I'll bring it out anyway.

Ya at least bring it out for static......we should be rain free for the next 5days.....so "Maybe" with some wind and sun...the field will dry out enough for this week end

I am making an effort to get some time on the simulator to help me since there has been so much down time

This entire year has been a challenge for me ......comparing amount of 2017 / 2018 video's  - less than 1/3rd stick time in 2018...uuuugh

Thanks to Barry for getting the engine tuned and doing the test flights, we got her flown yesterday. Sorry you missed it! Took lots of pics while Barry flew around. Sent one to Barry and he photo-shopped it to get it centered for me. Photo turned out very nice.

She just needed a few adjustments to the control surfaces. Ailerons and elevators needed more throw and less Expo. We decided that the one pound lead in the nose wasn't needed. And, I need a 24x12 prop for more pull and less RPM. The 24x10 flew OK, but the engine was turning over 7100 RPM which indicates the prop really wasn't quite enough for the 85cc engine. The first engine run was with a 23x10 which turned 7600 RPM! Way too small a prop. I could go with a 25x10 prop, but I already have ground clearance problems with the 24x10, so Barry suggested a 24x12. Valley View had one so I have it ordered.

She's a good flyer. A bit of a lumbering giant. Ha
Ailerons are kinda small for a 125 inch wing. But to scale she not supposed to be a acrobatic sensation. All in all a good flyer. Really cool to look at. Lane did a top rate job.

After taking the UV-20A out again recently, I decided the gear was just too weak for this bird. Am making a new gear out of 1/4 inch piano wire, which is insanely hard to bend! Plus, will find some stronger springs for the struts. Had to buy a new vise to put the bending jig in and then bolt it to the work bench. I managed to bend the wire, but it's tough, I tell ya. K&S doesn't make this jig any longer, so, glad I bought this one 21 years ago at Roy's. Bent one half of the new gear and will make the back half next. Always something to repair.

The new gear will attach slightly different from the old gear. The old gear is lots harder to duplicate as it has more bends.

Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on August 11, 2019, 02:07:04 pm
Made some progress on the Porter gear. Bent both halves and got them soldered together. Very solid! Still more work as I need to beef up the internal fuselage sides with 1/4 inch plywood. This is where the spring struts come thru. The factory design on this was just about worthless.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on August 11, 2019, 10:00:13 pm
Kept going into the day! Made some hold downs for the new gear out of large steel washers. Drilled and countersunk them for drywall screws. Seems to work nicely. Will use JB Weld to bed the wire into the mounting blocks to really secure them. Soldered the joints again after filing them down to make sure they were really soldered properly. Scrubbed the liquid flux off the joint with cleanser and washed in hot water. Painted the gear in rattle can polyurethane.  Going to work reinforcing the fuselage sides next, where the spring struts go thru on each side. Should have it all finished soon. Just in time for more days of 105 Deg F heat! Haha.

Got to the fuselage repairs today. Got the left side repaired and improved. That was the side that had the damage. I cut a 2x3 inch piece of 1/4 inch plywood to epoxy on the back side of the fuselage. Had to cut thru the instrument panel to get that large piece of plywood inserted. But, once back together, won't be that noticeable. On the outside, I soldered a steel washer on the upper spring strut to keep it from pushing thru the fuselage side. And behind the washer is another piece of plywood I made a disk to cover the overall hole and to add to the whole impact area. Won't look so bad once painted.

Post by: Lane C. on August 13, 2019, 08:21:59 am
Pretty much done with the repairs and mods, so, it's a matter of cleanup and paint touch-up. Added a dowel across the fuselage to really keep the fuselage sides from pushing inward under the stress of the struts being compressed. Barry, this dowel is one of your suggestions the day we flew her.

Last thing for today - installed the gear on the mounting block. I bedded it with Hysol and that takes around 18-24 hours to setup in this heat. Longer in the winter. I was going to use JB Weld but since I had plenty of Hysol I used that. Hysol is likely as good or better than JB Weld. In this application  anyway.

Got to fly the UV-20A yesterday. Got Barry to fly the first round, then I flew her 3 times. Flew nicely and the new gear held up fine, but the spring struts were still soft. I made an adjustment on them which gave more ground clearance. Very smooth flying bird. Even though 42 pounds, very easy to fly.

Barry got a video of some of one flight, but no takeoff. Landed smoothly but a hop caught the prop just enough to kill the engine.

Post by: Lane C. on September 18, 2019, 05:02:33 pm
After flying and seeing Barry's video, it was pretty clear I needed some propellor ground clearance with the Porter. So, To get the clearance and to help slow down the engine from over 7000 RPM, I ordered a synthetic Biela 4 blade prop @ 22x10 specs. This will give another inch or ground clearance than the 24x10 Xoar and help pull down the RPM's. I had a Dave Brown 2 bladed spinner, so cut it for a 4 blade prop today. Now, just needs balancing.  If all goes well, I can have it ready to fly for the All Scale Meet in a few weeks.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on September 20, 2019, 01:57:27 pm
Got the Biela today and did the final fitting to the spinner. Didn't take much after the initial cutting and filing yesterday. Full 2 inches ground clearance now with plane level.

While i had the UV-20A out in the shop, I wanted to enhance the exhaust dumps with a little more true to life color. this isn't easy to do! I'm using water colors thinned out to almost a wash. These can be completely wiped off at any time. In fact, I have already wiped off the first try and started over. When stainless or chrome gets really hot, it usually turns a shade of blue with some yellow stains in there. This attempt is better than the first one! When, and if, I get a color I like, I will clear coat it with Polycryllic and that will seal it for good.
Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on September 30, 2019, 09:24:55 pm
I wiped all the blue-ish paint off and tried again. This time mixed some silver and charcoal and made a pewter color. Looked OK, so clear-coated that. Will do for now.

Title: Re: 125 Inch Pilatus Porter PC-6 Kit
Post by: Lane C. on October 30, 2019, 10:32:30 am
Hi Darrell, it's literally Polycrylic Brand Clear Coat. It comes in several levels of brightness. I use satin most of the time, but it comes in flat and gloss also. Lowe's sells it, but for some reason Home Depot does not. If you spray it on, DO NOT thin it with water or anything, for that matter. The instructions clearly state not to thin. I tried it and didn't like the results. As it turns out, it sprays right out of the can even with an airbrush. That's prety much the story! ha. Lane
