Title: Hurry Home Honey CARF P-51D
Post by: Lane C. on August 10, 2014, 07:45:47 AM
Although I am possibly planning on moving out of this apt, I ordered the CARF P-51D and it arrived this week. Since it's relatively fully built, it won't be a problem to move if I actually do that. Right now, she's just sitting on the bench whilst I clean up my work room and apt. I have been putting cleanup off for too long. But, like to admire the lines of the D Model while I'm cleaning up.

It's the CARF P-51D with 100" span and 88" length. She is rated for an 80cc gas engine or about an 8 - 10HP engine or any sort. I will likely run an Evolution 80cc gasser but have my eye out for a KOLM 135cc inline twin 4 stroke gasser at 12 HP. The CARF is both a complex build and an easy build at the same time. A few things on a plane of this magnitude that are required are a full cockpit and pilot, Sierra retracts, and sequencing inner main and tailwheel doors.

The CARF Spitfire video I posted in the VIDEO section is with the KOLM 135cc 12HP engine and it really smokes.

This is the American Beauty. Very sweet paint scheme. Might do this one. Photo courtesy of Andre Nordheim.

OK,  that will be $5K maybe you can get by with about $4K.

Good Job, get er in the air.

Lane,  regarding the servos.  As with a conversation with Lawrence ...  we were talking about the Yellow Aircraft series of planes, and that these planes were all designed and built for 30 to 40 torque ounce servos or there abouts, because that is all they had back then.  But here we are putting 200 - 400  ounce servos on planes because we are told to do such by the hobby shops and "pro-builders".

One fellow [ Sam Parfitt ] put all HiTech 645's in his Corsair with the RCS 250 Radial.  [ remember that the RCS is the Moki, but if you buy a "moki" in the USA it has to be called a "RCS", since Moki is a "licensed" name and sold by that name in Europe. ]  So, Sam built his Comp ARF Corsair with ALL  HiTech 645's.  And the plane flies great and excellent.  There are no power surges, no digital servos fighting each other and such.  He has 40 flights on the plane.

And on my Comp ARF P 51, as one servo goes bad, I then replace it with the HiTech 645's.

On my Corsair.  I went with the JR 8711 at $110 bucks each and some hi-torque HiTech's on the flaps.  All, very much over kill, and the price was about $1300 or $1400 just for servos for the plane.  Sam Parfitt used all 645's and still doing great with over 40 flights on his Corsair.  So, just as we reach for the "newest, latest, strongest" servo, they really are not necessary.  Any one surface area on the Comp ARF P51 is not much larger than on a 85 inch P47 or other such warbird.  On the Comp ARF P51, there is a servo on each elevator.   Thus I would really consider going the less expensive way and use the 645's and do not get carried away with the expensive digital servos.  Thus that is 10 servos at $400, that is a $1000 dollar savings on servos.  I have the put 645's on my Comp ARF P51.

Hey Doc Bill,

I plan on using Futaba 3305's which are very hi-torque metal gear servos. I have tried HiTek 645's in the past and they just hum all the time. I prefer the Futaba 3305's and now have retrofitted them on just about all of my big planes, even throttles. I will also put the elevator servos right in the center of the fuselage (to save lead in the nose later) and use arrow shaft pushrods with 4-40 rods on the ends. Rudder will be pull-pull and be combined with the tailwheel steering. On the elevator servos, the stab surfaces are not really all that heavy and no use putting a load on them/weakening them by cutting a hole and burying a servo in the middle, thus the move to the middle fuselage. I prefer heavy pushrods for the tail surfaces unless it's just not feasible to do so. Even pull-pull is better than servos in the tail end (IMHO). Ha

I was planning on using the Evolution 80cc rated at 10.1 HP (vs the usual DA-85) but looked at HorizonHobby last night and saw that all of a sudden they say "No Longer Available." Just last week, I sent an inquiry to them asking if that engine was ever going to get Electronic Fuel Injection like the 60cc and they said, "No plans for that at this time." I wonder if now they are going to do the EFI thing anyway as they pulled it from sales? Anyway, the Kolm 135cc would be the elegant solution but very expensive. Costs the same as a Moki radial. But, if I sell several of my planes, I might get one anyway. Ha. Watch that Spitfire video I posted the link to and you'll see why.

I will amend this post to say on the Big Corsair, in addition to the Futaba 3305's, I used 4 LHS digital, metal gear, hi-torque servos I bought from Lee Rice for the flaps. They are rated at 200 Oz output each!!! Haha. A bit of overkill for sure. But, got a good deal on them.

While it's just sitting on the bench, I wanted to sand down some ugly "seams" where they joined the lower part of the fuselage to the upper. Man, it was hideous.

The right side untouched.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_4352_zps80544f9a.jpg)



The Left side sanded down.
Sanded down the material and gave it a coat or two of primer. Now, I can see the holes left in the joint and will use some bondo to level it out a bit. This is not a real noticeable part of the plane, but it should have been done better than this at CARF factory. This will get a double layer of final black/white paint with the invasion stripes, so hopefully it won't show at all. I'll go very light with the filler and just do a small amount at one time so as not to have to do any more heavy sanding.

View in normal position. Sanding not as apparent at this angle. Some wet sanding with 1000 grit should blend it all together.

Found out today a KOLM engine takes about ONE YEAR to get one. So, that narrows it down quite a bit to the MVVS 80cc.
Title: Re: Composite ARF P-51D

my zdz 80 flies er quite well, and does not have the balance vibrations probs of the DA85
Title: Re: Composite ARF P-51D
Post by: Lane C. on August 26, 2014, 09:53:07 PM
Pretty sure I'm not doing another DA-85. The ZDZ's are available, but haven't looked into one yet. The MVVS 80cc  (Evolution before they discontinued them) takes a couple of weeks to get one from Europe.

I looked at TBM and they do not show an ZDZ 80cc, but have a new 90cc. They didn't give the HP output, but runs a 28 x 12 two blade prop, so, must be rather grunty.

Can you take a pic or two of your engine setup in your spare time? haha. Maybe I can look it over next time you have it at the field. Using a pitts style muffler makes a close fit on the left side. Cannister muffler might be less work.
Title: Re: Composite ARF P-51D
Post by: DocBill on August 27, 2014, 07:56:35 AM
I don't think that the 90 will run a 28 x 12.  That is the prop on my DA 120 and it is turning about 5800 !!!   Really too prop much for a 90cc.  Prob a 26 x 12 is more realistic.  But even at that the 90 should really pull the bird.  I am flying the dizzy 80-cc at 3/4 throttle on the up stroke of a loop or such.  Sometime full throttle.  So the 90 should be just fine.  ZDZ has had better luck with there balance needs.  But the DA 120 balance is quite nice.  The ZDZ 80 in my P51 does not seem to have too much vibration and have been happy with its performance.  The fellow that had the plane before me found the  24 x 12 was best for this engine.  I purchased 2 props a 24 x 12 and a 26 x 10 and then put on the 26 incher, this flies just fine.  Will try to bring out the P51 with the next flight.  To hot to work on the planes right now, and too hot to fly.  There are some pretty large solid aviation high density plywood stand offs that can be made for the plane.  And he built up the internal mounting with carbon fiber and WEST systems on the inside and out side.  This is A BIG FAILURE IN THE DESIGN.  DO NOT MOUNT THE ENGINE ON WHAT IS THERE.  It will not hold up.  You MUST re-enforce this area with carbon and WEST System.  and then with the rear entry carb you will get fuel residue in the entire front area around this engine mount.  Thus it is good to place WEST Systems over the entire inner aspect around the front mount area so that the oils and fuel does not make it into the "composite" of the plane and the foam of the "composite".
Title: Re: Composite ARF P-51D
Post by: Lane C. on August 27, 2014, 08:56:38 AM
I agree on the engine mounting problem. This needs to have at least a 1/2" or maybe 5/8" plywood firewall reinforcement epoxied to the glass from the top to the bottom of the fuselage mounting area to bolt standoffs to. Carbon fiber tow with epoxy added all around that to make it more secure. A guy by the handle of "Hornitpilot" did his CARF P-51 with a ZDZ 90 and beefed up the firewall like I just mentioned. I may start looking into the ZDZ 90J as well as the MVVS 80cc. They are about the same price. Lee has mentioned that the rotary valve engines can be somewhat problematic. Do you have any trouble starting or tuning yours?

Called TBM this afternoon to ask about the ZDZ 90. Wow, out of stock and they are not ordering any more till they can get a reliable spare parts supply/delivery commitment from ZDZ. It's looking more like the MVVS 80cc is going to be the engine!
Title: Re: Composite ARF P-51D
Post by: DocBill on August 27, 2014, 07:45:44 PM
Intended to say:  he made some standoffs out of high density aviation plywood for the plane.

Yes, please go ahead and build up the inside with a high density plywood or 2 pieces of 1/4 inch oak and epoxy the two together with the grain at 90 degree angle to each other.  This will make a really nice wooden reinforcement for the inside and just turn the plane on its nose and dump in the WEST System epoxy and let her build up.  Maybe even 4 or 5 ounces of the stuff.  And paint 2 or 3 coats of WEST System to the whole inside of the plane back to the first bulk head.  And paint the bulk head with WEST Systems.  DO NOT USE FIBERGLASS RESIN ON THESES PLANES IT WILL MELT THE PLANE.  On the inside of the foam there is a 1/2 mil coating you can sand this a hair till you get into the foam, then the WEST Systems will go into the foam and even better strengthen things up.  I would only use built up plywood stand offs on the nose since the area of the stand offs might be the area of lets say 5 square inches on each side.  [ my plane has one stand off on each side with the carb in the middle ].  Do not use the aluminum stand offs with the area of a nickel on such a plane.  All of that force and weight distributed across 4 stand offs the area of a nickel is crazy.  If you can do a 1/2 cut down cockpit,  i.e. end the lower section of the cockpit at lets say what would be the pilots hips, then this will give you room to mount the gas tank in the CG.  You will need at least 40 ounces.  I do not think that a full cockpit will fit in and get the gas tank in as well at the CG.

When I finally get an engine, I can get a bit more serious on the design of the engine mount. Took me a while to get the details of the Saito Radial engine mounting worked out on the Corsair.

I finally got a reply from Vogelsang and a price quote on the KOLM IL 135cc. They said a 3 to 6 week lead time is to be expected. I pinged them back to ask how that translates to the real world time frame. I suspect that the one year wait is the "real world." May take a few more days to get a further reply. At this point, No hurry in making a decision on the engine.

Problem solved.  I will sell you my dizzy 80 for $2400 bucks.  Can get it off the plane with a chain saw for you today, will deliver tonight.  And 2 props.
Title: Re: Composite ARF P-51D
Post by: Lane C. on August 28, 2014, 08:00:29 PM
hahaha.

Today, got a new reply from Vogelsang stating that delivery takes about what he quotes on his first e-mail - 3 to 6 weeks. He said he sells lots of them every month and some are on the shelf ready to ship. So, maybe the guy that told me that there is a one year wait is more interested in selling HIS brand of two strokes to me! I can wait that long. After I pay off this month's CC bill, I will order one or the other.

I was coming home from Lake Bridgeport today and saw the Famous Doc Bill Chambers office on Hwy 199 in Azle. Wow, BIG LETTERS on the front of the office. Cannot miss it. ha

Dr Vogelsang sent some pics of the KOLM 135 in the CARF P-51. Even offers an installation kit. Take up a lot of room for sure. I think these are photos of the short version engine before they made the long nosed version, and used prop extensions for their prototype. At any rate, lots of details in making this engine fit in the CARF P-51.

I ordered a couple of scale detail parts for the P-51. Pacific Scale has some custom exhaust manifolds and some air intake filter covers to improve on what the CARF folks did.

The resin part will fit inside the cowl and poke thru after I cut the long oval shape in the cowl. then, the brass tubes get epoxied into the resin part and some other details to make them look like welded steel exhaust stubs. The finished parts in photos look very real. The resin parts are surprisingly heavy.
(http://img.photobucket.com/albums/v228/numskin/planes/IMG_4407_zps8e80702a.jpg)

A rough idea of how they go on the cowl. The air intake covers seem a bit small for the CARF P-51, so I e-mailed Tony to ask him if these are the right ones. Look like they fit the 1/5 scale Mustangs. Guess I can skip using those if it comes down to it, as they don't add visual impact like the exhaust parts.

I was in the middle of moving before Christmas and this arrived on my porch at the Apt. Ordered it back in august. Came in from Czechoslovakia thru Chief Aircraft. MVVS 80cc gas engine. I hope to get some work done on the CARF in 2015. The MVVS 80cc was sold as the Evolution 80 by Horizon Hobby until it went back to MVVS brand. Guess the license ran out. Not sure, but I was told it wasn't because it was a problem engine. Horizon still stocks parts for the Evo 80 engine.

When I get the garage cleared out somewhat, get some insulation in the overhead area, get my bench setup, and get a heater, I can at least do some work. Just happens to be dang cold all of a sudden! ha

Tim, there is one or more videos of this engine flying a CARF P-51 on Youtube, looks and sounds good to me.
This just says "1/4 scale" Mustang which is actually bigger than the CARF at 1:4.5 scale. Really hauls it around.

Lane,
Is a permit required where you live?
When I built my shop back in NC I told the building permit people that I intended to build a "storage" shed.. no power or water,,,,just a storage building.
Permit was REALLY cheap.

Once it was signed off I did no own electrical (used the hidden PVC entrance conduit I had in the slab).
This little trick was told to me by the county zoning commissioner...LOL...........

There ARE ways to get around some of the "extra" expenses.

Not sure if I need a permit or not. You can "get around" things, but if your shack burns down then your home burns down, then starts a grass fire and burns you neighbor's house down, due to faulty or improper wiring, or any other "rigged" system, guess what, you don't get a dime from the insurance. In fact, you will be sued for lots of damages and etc. It can be very costly to save a few bucks!!! hahaha. Now, that's a bit of exaggeration, but cutting corners is something you have to be careful with.

Post by: Lane C. on January 14, 2015, 10:42:02 PM
Back to some CARF P-51 work. Not too much I can do right now as far as actual work. So, got the fuselage and engine out and looked at what I had to work with on the engine mount. Some blue tape is holding the engine in place. Spinner is in place. To mount like this, the engine will hang out the bottom of the fuselage. I might find an extension that fits to move it back slightly and have less cooling fins in view. This is how it starts for me. I have to start getting some thoughts in my head by trail and error fittings.

Of course, this brings the question of how the muffler will fit. While I don't mind a cooling few fins hanging out, the muffler needs to remain hidden inside the fuselage. So, that opens another can of worms, maybe. But, it looks pretty tight in that area. To me, this is the biggest headache on the plane, any usually any plane - engine mounting.

I have been watching a YouTube series by Hornitpilot on his CARF P-51D. He has a fairly no-nonsense idea of mounting his engine and getting it going. Now, some like to go to great lengths to totally hide their engines from view, and that's OK with me, but I am for making a few concessions on scale appearance since I am not a Top Gun competitor. Once buzzing by at 90 mph, you won't notice if the fins are showing or not. Ha. My emphasis is making them fly good, look good in the air, and have a little pazzazz in the pits.

Unique pictures. Everything is silver. I agree you have to fit, think, try, fit some more. Have to think about it and stay ahead. Always thinking ahead.  Lee didn't have any big air flow revelations on mine. Might build a ramp to shoot air down toward engine. I actually bought some flexible plastic tubing at HD. I think I could direct all the nose intake air around directly onto head if necessary.
Title: Re: Composite ARF P-51D
Post by: DocBill on January 17, 2015, 09:04:43 AM
Hi Lane,

The fellow that put my Comp ARF P-51 together, placed about a 2 inch or 1.5 inch prop adaptor extension onto the front of the engine.  This allowed him to place the engine aft somewhat, [ much more so than in your picture ].  Come over and take a look at it if you want.

He played with a lot of props for this plane and this 80 engine and found that the 24 x 12 did the best and gave the best speed and pull in a climb.   Right now there is a 26 x 10 on the plane and she is not as fast as with the 24 x 12.

Most of the engine manufactures seem to over state the power of the pull of their engine by a factor of 1 or 2 or so.   Thus, some engine will say we can turn a 32 x 14 and then you find the best prop is a 30 x 12, and at those size props your going thru some money to eventually discover  the best prop. 

Thus for your 80 I would try a Xoar 24 x 12.  Even at this price,  these will set you back some.  I just ordered 2 more 28 x 12's for my 120 on my corsair.

Hi Doc Bill, I need to see what bolt pattern this engine has. It may be same as a Desert Aircraft 6 bolt. If so, there should be extensions available from Sierra. Might be nice to set back at least one inch. Look at hornitpilot's video and you can see how his looked. Not a Top Gun install, as engine shows out the bottom, but certainly usable. I don't want this to be a 2 year project. Although busy with the new house, I'd like to be able to fly the Mustang this year. Dunno.

https://www.youtube.com/watch?v=yr583nu5_lY

I have a few props from the big Zero with DA-85 that will likely work. Have to look at my black book to remember what I was running.

I'd like to look at your P-51 a bit closer sometime. Drop me an e-mail with your info and I can setup a time to come by.

Post by: DocBill on January 17, 2015, 01:24:54 PM
Hi Lane,

Couple of things.  This "comp arf material" is really weak when it starts to give.    I would not have cut a hole in the structure leading up to the mounting of the engine.   Go inside, or outside and add carbon fiber over the entire structure.   Plan on using west systems to coat the entire inside of the front of the plane.  The fuel is a disaster for the "composite" material.   The bulk head / motor mount for the engine, behind it, needs a layer of carbon or 2 or 3, then 1/4 in highdensity plywood, then a layer of carbon that spreads out onto the bottom surface, each side and the top ... to then spread out the load across the front of this plane.  Better to do it once "really right" than to re-do it.  But once you have fuel and oil in the composite material the party is over.

Regarding his air tank there is a built in spot for it to go.  The elevators servos can go in the elevator as well.

I started laughing when he said his screw was too long to hold the spinner on.  It's like, geeeez, dude didn't you put all this stuff together at home, first, 5 times to make sure it all went together well and correctly.

While waiting for one lousy power switch for the S-Bach, I am working on the P-51. The engine is where I usually start, so, began making a heavier firewall using the CARF factory 1/8" plywood as a template. I made that one fit, then traced a new one out of 1/4" plywood and made one more to boot. So, the new firewall will be 1/2" thick and will be bonded all around with epoxy and glass tape. The pencil lines are where I will cut holes to possibly use as exit air vents as cutting them later would be a real problem. I need a prop extension to push the engine back a bit to clear the Pitts style muffler on the fuselage. This will probably make the engine cylinder head all inside the fuselage. Might need a clearance hole for the spark plug. Cooling on a P-51 is always an important item to consider DURING the build, not after you've crashed due to an over-heated engine! haha. So, I will give lots of thought to keeping her cool BEFORE I get to the field. Once I get an idea of where the prop extension puts the engine, I can build a mounting box and then hang the engine off that.

I'll cut out that composite piece with the pencil lines as it really is in the way of making a solid firewall there.

Longer shot of the engine area where I cut the opening for the 32 ounce gas tank. It may have to be opened more later, but this allows me to see inside to glue the firewall in place.

Got the two 1/4" plywood shapes epoxied together last night. They are VERY hard glued! then, this morning I cut out the composite firewall to see how she fit. I still have some rough composite fiberglass around those fillet areas that need some 60 grit treatment, to allow the plywood to fit tight against them. While I have that area open, I used 60 grit sandpaper to rough up that whole area around the new firewall so I can take Doc Bill's advice and give that area a light glassing to seal it up from gas spills. Only get one chance at this, so, going to make it clean and strong. Still need to cut those air exit holes in the firewall and smooth them out before I glue it in place.

Still in the mock up stage, to see if I got the basic mounting parameters lined up. Looks pretty close. I moved the firewall just a bit top/bottom - left/right to get the spinner to align with the cowl. I am using stand offs from a DLE-55 I happen to have on hand. With this setup, I will need a 1 inch prop extension and the engine is all within the fuselage. Spark plug may need a clearance cut on the bottom. Problem now appears to be the MVVS Pitts muffler - it appears a bit too large for this setup. It's really a fatso and not sure what else will fit this engine. It appears to be in conflict with the firewall, not the side of the fuselage. Might have to go to the Evolution 80cc Pitts muffler as it looks quite a bit trimmer all the way around. Muffler not shown in these photos.

Also, not sure I will go with standoffs as they may flex with the power of the 80cc engine, or go with some heavier standoffs with 1/4-20 cap screws. Or, I'd have to build a plywood engine box to carry the load and make it to the same dimensions as the standoffs. But, the carb would be inside the box. Not a show stopper, but it would need some cutouts to get to the hi and low speed needle valves.

Using this spot with the arrows on the fuselage, below, I assumed it was going to be pretty close to level when inflight. Setting this to ZERO degrees or dead nuts level with the angle finder, the engine shaft indicates MINUS ONE DEGREE alignment with the spinner in line with the cowl. So, if this logic is correct, I have one degree down thrust. But, the spinner aligns with the cowl, so that's the important part.

Here is the engine box that will replace the standoffs. All of this is kinda rough right now, but they need to be glued together and then trimmed at the bottom and left side pretty close to the bolt holes to allow the muffler to fit under there. Corners rounded, etc.

Post by: Lane C. on December 22, 2015, 07:09:12 PM
Hi Darrell, thanks. I don't think it will be more lead than the plane can handle! haha. I ordered the extension thru Ziroli Plans, but it's made by Sierra. The plane is pretty light by itself. Elevator servos in the tail add more weight to the nose than anything.

Got some more done on the engine box today.

Everything still in mock-up stage. Got two plywood layers epoxied and a few more to go. Only two at a time to keep them square and plumb.
(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6507_zpsdcnpqggk.jpg)

Kinda rough looking here. Will clean up OK.
(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6506_zpsedxevm40.jpg)

Large Mouth Bass anyone? I'm hoping this will be a strong engine mount. Once all the parts are epoxied together and the firewall Hysol'd in place, should be rock solid.

Not much accomplished today. But, got some lines on the engine box for possibly cutting down in size. This is the proposed shape. Bottom of box will be trimmed a bit short to allow room for the Pitts muffler. Sides will slope to match the sides of the rest of the engine compartment. Both top and bottoms will have rounded corners.

Moved forward to getting the engine AND MVVS muffler installed today! Wow, kinda thought that muffler wasn't gonna fit, but it did.

The arrow points to the only spot that actually touches the skin. I had to move the whole engine another 1/4" forward to get the muffler off the firewall, with another spacer. I may be able to cut some of that area off and weld a plate back on there. We'll see. Doesn't need much relief.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6515_zpsg2kxkubg.jpg)

Another shot of the bolt up. I think once I get the corners and sides cut off and sanded it will be a clean installation.

Doc Bill, following your suggestions on making the firewall beefy. It's turning out pretty nicely.

Yep, working on the CARF on Christmas day! This engine mount has had me going since I started. I want to see the almost finished mount before I stop and glass the inside of the front fuselage with West Systems Epoxy. I cannot put the firewall in place before I do that. So, I decided to add a 3rd 1/4" plywood thickness to the firewall for extra strength. I also cut the muffler to make extra clearance against the fuselage. A small plate of aluminum welded over that gash and it will be good. Not absolutely sure of needing the same thing at the back end of the muffler, but might have to cut some off there too. I cut down the sides of the engine box plywood before I join the last two sections with epoxy. Just about got done what I think is the most challenging part of the build.

3rd plywood firewall layer.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6528_zps0pbat8ow.jpg)

The 3rd ply is there, just hard to see.

Hi Darrell, I'm still going. Almost 8 hours on this today. This is the last go round. I'm pretty beat.

I'll have to find someone who can weld aluminum. Shouldn't be too hard to find. I need to make a piece to fit that hole first.

All the wood is to replace standoffs which can twist around with a large engine like this one.

I'm sure these look like repeats of earlier pics, but to the Trained Mark I Calibrated Optical Eyeball, they ARE different! ha

This one is definitely new. Cut out the air exit holes (hope that works, anyway).

The throttle arm on the carb wasn't really positioned right. The fuel barb is right in the way. So, needed to move the arm down a bit. Had some G-10 on hand and made a new throttle arm.

Laid the arm over the G-10. The smaller G-10 arm is there as a go-by for the end of the new one.

The set up is quite nice.  This will work great.  You must use some West Systems all over the forward interior, on the wood and in the engine compartment.  You will be losing some gas and oil in those compartments which will contaminate the foam composite. 

Thus far superior work.

Kinda got a surprise on mounting the ignition module - the plug wire is too short to place it on top of the engine box! Dang! Never thought that would be the case. It's gonna have to go behind the firewall on the side of that sloped section. No way to make the plug wire longer, that I am aware of. It's all sealed from the factory.

Pretty much the layout on mounting.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6618_zpslh0k8j7k.jpg)

plug wire goes thru the engine pipes out to the unit. Will require some rubber tubing and foil wrapping over the wire, I suppose. Plug cap and maybe some wire will be hanging out the fuselage too. More dang.

Darrell, sad part is, Tony Howard of Pacific Scale Aero passed away suddenly and no more of his exhausts are available. He made some air filter intakes for the side of the fuselage also. Those are the plates with 32 holes in them on each side of the lower forward fuselage. I have a set of those too, but will have to think on using them. The CARF fuselage has them molded into the sides, but according to Tony, they are way too big for the scale of the model. I'd have to sand those off first, then cut out for the replacements and glass them in. Requires some thought. Most don't/won't know the difference anyway! ha. Problem is, even the CARF doesn't have the molds straight so drilling them out is a problem, of its own.

Got a load of supplies in for the Mustang.

Bob Violett sells two items I needed. First is the Ceramic paint for the area next to the muffler. Also, for the plug wire running thru the pitts twin pipes, is the Violett ceramic blanket.

From a boat building supply house is the West System Epoxy resin and hardener. I still need a digital scale to weigh it out before using.

From Chief Aircraft, I have a Hysol Epoxy kit. This is fairly expensive glue but is considered the best for serious RC work.

Guys, on the exhaust stacks. I had to cut them off to trial-fit the engine. Didn't want to cut holes in the fuselage when I wasn't sure that the MVVS muffler was going to fit. When I have that plate welded on, I will reattach the exhaust tips.

Made a paper template for a baffle. Next, a balsa template to get a better fit. Final baffle will be  plywood. It will have to be split down the middle to insert it. I blatantly borrowed a guy's idea from one of his P-51's off the RCSB board. But, if it works, it works. Idea is to keep the air going over the lower half of the engine.

Not a lot to attach it to, so may have to kinda "float" in there with only a couple of screws holding it in place. Like everything else on a CARF, this may have to be adjusted or even scrapped later. Never know how it's all gonna play together until you're done.

I knew your OCD nature would not let those exhaust stacks go unpunished. Just like those freakishly long screws on the baffle may not survive either.

I can probably find some shorter screws! Ha. Good thing about those screws is they take ball-end allen wrenches. Very handy to have! Right now, it's all mockup stage. I gotta find a welder out here who does aluminum on a walk-in basis. Found a guy, but he's kinda busy. Once I get the muffler tips welded back on and get the firewall epoxied  in place, I can cut the tips off again, a bit longer. Now, question is, baloney sliced or straight cuts?

I finally got the firewall Hysol'd in place yesterday. Pretty solid stuff.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6786_zpsgnodmxaw.jpg)

I changed up the choke servo setup to the opposite side. This way, I can use the upper part of that 1/4" panel to mount the retract control system above the throttle servo. Side panels are not glued in yet - gotta think this over some more.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6787_zpsut5kojfs.jpg)

Not sure this adds anything different, but one more pic. I put the fuel line in place to see how it was going to play with the throttle linkage. Looks OK.

Definitely true. Have to work on it, let sit, work, let sit, etc etc. I spent several weeks on Mustang cockpit off and on including side walls, floor, seat, instruments, seat belts. I started with kit and added my own stuff too. Cockpits are a lot of work. Do you have plastic model paints, brushes and all? Also model plastic glue does not like vibration; it fails. I like E6000 silicone goop stuff I think. My 2 cents worth.

Hi Darrell, I use CA and epoxy on vacu-formed ABS. Got paints. May use some silicone glue on this one as well. This kit will add a pound to the model and that's BEHIND the CG. Lots of resin parts which are HEAVY. Plus pilot. Might have to do an abbreviated cockpit. Ha. but, on a cold day like today, not much else to do. I'll work this in the house so I can be near the central heat and bathroom.

Got a 15" Warbirds pilot today from Ziroli. Supposed to be for 1/4 and 1/4.5 scale warbirds. Looks about right so far. Hope he looks good in the cockpit. The seat bottom needs to be brought up another 3/4". Lots more to go on the cockpit. Also got my UP2 pneumatic valve and air cylinders for the retracts and inner doors. Supposed to be one of the best brands. Worked around the outside of the house today, so not much done on the P-51.

Pretty sure the parachute is wrong on this pilot as its on his back, not under his bottom. The seat pan of the P-51 appears to be made to sit on the parachute. I took off the lump for the chute and left the chute shroud. I think they took a short cut and used the parachute rig off the smaller pilot and hung it on the larger one. Shame on them.

Got the nerve up to cut the access panels out for my power switches and air fill, air pressure gage, and gas fill dot.

First pic is the panels cut and the piano hinges installed.

Second is the panels wide open.

Third is the outline of the under glass area that needs to be trimmed down for the three power switches to fit in there.

These are the locations of the access doors on the full scale plane and several guys use this area for their doors.

I cut them with an Xacto blade first, scoring them a bit, and then used a Zona saw with very fine teeth. Works pretty well.

I keep hammering away at the switches. Feel I've got a solid setup now. These things take lots of time.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6844_zpskkgce8pd.jpg)

I'll replace those servo screws at the bottom with 4-40 bolts later. And, when I get some carbon cloth I'll reinforce that side of the fuselage too.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6845_zpsedlftpro.jpg)

All lines up OK and door closes fine.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6848_zpsmxi4tfcd.jpg)

Now to the smaller door with the air and gas fills.

One note on the hinges. Next time, rather than the small 3/8" piano hinges, I'll use some wider ones because the narrow ones put the holes too close to the edge of the cut. In other words, the material is so thin after you drill the holes that the holes tear out.

Nice progress Lane. Should be ready by June for the qualifier?
Yesterday I installed the engine on the Carf Spitfire and what a beating getting the engine, cowling, and spinner all lined up straight with about a 1/16" gap between the back of the spinner plate and the cowl ring. Got it done, but O' what a beating that job was.
The big 190 is still in the trailer. Haven't done anything with the canopy as yet.

Thanks Darrell, and Sonny,

I don't think I could fly it in the June Contest even if it was ready. I might fly it period, but not in a darn contest! haha Sure way to crash and burn. haha

Cutting the canopy is easier than fitting the new engine, so, won't take long to get that out of the way.

Try to do something every day. Today, got the UP-2 retract servo and mounted it on a 1/8" plywood board and found a place for it in the fuselage. Seems happy there.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6856_zpsnqpj9twi.jpg)

Kinda dark in there but it's mounted on top of the choke servo. As usual, copied Matt's CARF P-51 build (from Radio Control Scale Builder).

I'm back on the rear radiator door. Found a build thread on RCU and used Canuck1's idea for a home-made Robart style hinge. This is only CA'd for the moment and will go in with epoxy to fix the hinges in place. I need a cross bar in there and a servo attached to slave it to the throttle, or flaps, I suppose. I only have 7 channels, so don't have an extra channel just for this.

Got back on the rad door after lunch. Epoxied the hinges in place and added some extra side supports. Glued a cross bar on the door and had to sand the pocket the door moves in a bit to get smooth motion. Now, I need to hook up the servo, but am tired today. Will do that next time I work.

This door thing turned out better than I envisioned. Ha. Ya never know.

Got back on the build today. Pretty much got the rad door done, but need to make a longer servo arm to get the full throw I need. This is a mini-servo and I don't have any long arms for it. Back to the G-10 sheet.

Made a platform for the servo to sit upon, epoxied it in, and then made a servo tray so I could just remove it and be able to work on the servo outside the fuselage. It's pretty tight in there. Did all the construction and preassembly outside the fuselage.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6880_zpslitrzc1n.jpg)

Here's a shot of the door opened.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6882_zps7ehftk2s.jpg)

Opened from the side view. Could go a bit more down.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6885_zpszjv9jgeo.jpg)

Could go a bit more up also. A longer arm will take care of that.

Waiting on some retract parts on another ARF I'm putting together for a club member and pulled out the P-51. Kinda lost track on where I was, so decided to work on the canopy. Stuffed the pilot in there for fun. Not sure I like this pilot, but cannot find a large enough paint-it-pilot.

The, so called, instructions are very incomplete content wise and the build methodology is pretty much left up to the builder himself. That's not a good thing for a step-by-step builder such as myself. You get step-1 then step-5, step-11. Just too many gaps in the instructions. My eyes glazed over then went crossed so I had to quit for a while.

The landing gear is too far back when extended and I think the thing will be prone to nosing over. The wheel covers installation is just kicking my rear-end to the point I hat to put the plane into purgatory, that is in a closet in a spare bedroom with the closet doors closed and two airplane wings propped-up against the doors. It ain't getting out.

I do have the paint, stencils, and graphics for the thing.

Anyways, I've gotten into "trying" out the 250 class racing FPV quads. The bug has bitten. What a hoot!

Spent a number of more hours on the front windscreen. Not only cutting out the holes for the "glass" but then fitting the "glass" from a sheet that CARF supplied. Also fit the glare shield to the instrument panel area. It needs painting flat black before I can install the front windscreen. It's roughly fitted and I think it needs to move down a bit or my pilot won't be able to find the runway.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7442_zpspfeeqovh.jpg)

Sonny, I read the instructions. The photos are good, but it is hard to get an idea of the orientation of them without having the parts handy. They do leave out a lot of steps and warnings about throws, and real details. Lane's photos would be a great help if they were added to the manual.

Glad you guys are building those and not me.

First stab at doing a sliding canopy.

Got my canopy rail set from Ziroli's and cut them down to 8 inches. On a test run, cut some Basswood to same length and ran thru the table saw at 18 degrees bevel and dado'd out 1/8 x 1/8 inch. It fit pretty well against the fuselage side.

Added the guide rail for test fit.

Gap for the canopy frame and plywood corner piece for the attachment screws.

Title: Re: Composite ARF P-51D
Post by: Lane C. on July 26, 2016, 05:06:46 PM
Off on another tangent. I have spent many hours trying to decide how to keep that big 80cc engine cool. The convention is allowing the hot air to travel thru the fuselage and dump out the back end. That's asking a lot of air without lots of direction. I decided to just dump it out as soon as it goes past the engine and the firewall in front of the wing. It's only a small concession to looks. I've seen many more atrocious mods to P-51's such as obscene cutouts for the muffler and such. This will look OK, I am convinced. But, at the cost of the P-51 all ready to go, it's more about protecting the investment. My goal is to keep that prop spinning until I taxi in after the flight.

Firewall with cooling holes.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_6786_zpsku1kaz8p.jpg)

Aluminum plate to cover holes and deflect air below and out. Still have plenty of room for the gas tank and other goodies.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7488_zpskm0xygm6.jpg)

Proposed air exit cutout.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7493_zpsulr1haoo.jpg)

For you techies, I made a paper template of this fairly complicated part. It's made of aluminum sheet in 3 pieces to enable installation. The two side panels will remain in place and the center can be removed if needed. Almost anything can be fabricated if you take your time.

Made a fuel tank mount today. Wanted to get it up out of the way for things going on below. Blocks will be Hysol'd and screwed in place. 32 Ounce Red Wing tank will be held in place with Velcro. Photobucket must be down today, so these photos are kinda skewed. But, you get the idea.

Also, by looking at the photo, it looks like I have a gas tank for an instrument panel. Nope, it is set back a couple of inches to allow plenty of room for the panel.

Title: Re: Composite ARF P-51D
Post by: Lane C. on July 30, 2016, 10:30:46 PM
Darrell, it's just wasted space otherwise. The air lines can be routed up there as easy as anywhere. Plus, it's a fairly easy location to make adjustments and give it a look over. And more usual than not, you end up putting lead in the nose of a warbird. I had to put the ignition unit there on the other side, so that ate up room for the gas tank, and might as well use that area for the throttle and choke servos. I will look at making a shelf for the batteries below the gas tank. So many things to decide on where to put them and how to mount them. CARF's are a blank canvas.

I added some 5 oz cloth to the bottom of the engine bay and aft of the engine bay. This is handy for a gear up landing, should it happen. That 5 oz cloth makes it twice as strong. Will also do the same for the radiator air intake under the wing. It's pretty soft as it comes from CARF. Might even add some carbon tow as well. Also coated the firewall bulkhead with Z-Poxy resin to seal it off from oily gas leaks.

Well, here it is, my method of keeping the engine cool! Throw hate, like it, or love it, I feel it will work fine. I added a pressure lip out of G-10 to create a low pressure area to pull the air out the exit hole.

Moved to the tail and made the mount for the tailwheel. 1/8 inch plywood Hysol'd to the fuselage. The glasswork in that area was almost nonexistent. Appeared to be gelcoat/paint and that green spongy stuff. Nearly caved in just cutting out the tailwheel doors. So, I sanded down to bare material and added an overlapping layer of glass cloth to the end of the fuselage. Much stronger now.

Also sanded and primed the ugly seam on this side while I was back there.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7581_zpsvb1jyudz.jpg)

Kinda close working back there. Guess I'll have to cut another hatch for the rudder/tailwheel steering servo.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7585_zps0wrji96m.jpg)

Screws on top of the glass are just to allow the Hysol to setup. They'll be below the surface after that. This area won't look too great, but will be the least seen. Ha

Still on the tailwheel retract. Needs a servo to steer with and a servo for the rudder. Both will mount tandem style aft of the retract. It will mount almost like it sits with the spacer block to give the servos room to fit.

Added a layer of 5 oz glass cloth in the belly air scoop with West System Epoxy.  Hard to tell where the new and old glasswork is, but it's there. After that setup, added a hank of Carbon Fibre tow to stiffen it up more, between the two hanks already installed at the factory.  Looks like I'm gonna add another hank as well. A belly landing would take a pretty hard hit on that soft underbelly. The 43 C.I. air tank will go here.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7606_zpslplsjk6y.jpg)

Got the steering servo mounted behind the retract unit. Seems to work well. Gear down and locked here.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7599_zpsi99xn9bj.jpg)

Gear retracted. Pretty simple steering setup. The rudder servo goes aft of the steering servo. That will be an interesting installation.

I got the rudder temporarily mocked up today and measured the throw and it's about 20 - 25 degrees each way with the pull pull wires hooked up. It moves more just hanging without wires, but it appears the full install doesn't allow that much movement. I went with the CARF suggested setup. Seems to work OK. There's no practical way to cross the pull pull wires with this tailwheel in the way.

Final setup on the tailwheel assembly. Removed the aft end of the plywood support since I no longer need it for the rudder servo. Used carbon tubes to route the pull pull wires past the retract. I angled them to make the wires go wider than the gear door opening. Will use one more tube up forward to get past the aft radiator door servo without rubbing. That door will be hooked to the flaps with a Y-Cable to open when flaps are down. Was going to use it to help cooling air exit, but changed that plan. One for the cool factor, ha.

Installed the 43 cu inch air tank below the rudder servo.

Rudder servo setup per CARF booklet, or roughly thereabouts. I will use a wider servo arm.

No doubt about it, Lane, it is tough getting everything in back there. I cut a hatch in the glass fuse side and then glassed the hatch back permanently. Major repair there would require cutting back in. But glass can be fixed and repainted. Now your tail wheel does rotate forward, right? That caused me steering headaches since the servo was up front. good progress there.

Post by: Lane C. on August 20, 2016, 06:39:56 PM
Ha ha. Well, I reversed all the rudder setup I had and went with rudder swing off the tailwheel steering servo after all. It's just a lot more efficient and less to mess with having two servos. Had to make up a 4-40 rod to run to the opposite side of the servo arm to get the rudder to swing correctly. Sometimes you just spend hours working and then trash it all for a better idea.

The 4-40 rod setup looks like this. Soldered on one end, adjustable on the aft end with lock nut.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7629_zps4zntguk6.jpg)

As the retract assembly is slid into the fuselage, the rod gets moved out the hole in the rear.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7628_zps3xi4pi6q.jpg)

Clevis gets hooked to the rudder post while the servo arm is pulled all the way to one extreme.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7627_zpskn6zexgg.jpg)

Rudder hinge pin is slid in and all finally all hooked up. You couldn't do this with Robart Hinges.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7626_zps5glalnsh.jpg)

All hooked up and showing how much travel is possible. Won't need near this much, but it works much better than the pull-pull servo setup.

Yep, to those sharp-eyed builders out there, the rudder should point the same way as the tailwheel. I reversed the pull-pull wires on the tailwheel and that fixed that problem. Didn't have to change the rudder rod.

Roy's has the Butyrate Thinner, but it's getting kinda costly. I used to buy it by the gallon can there, but they haven't had that for a couple of years.

Got one more Hi-Tek mini servo for the other elevator in today and finished up the empennage. Hooked up the elevator servos to run the same on both sides to use a Y-Harness vs Matchbox or Rev Y-Harness. Keep plugging' away and it all adds up. Guess I need to get back on the sliding canopy.

This CARF model comes in the polished silver finish. Are you going to sand it up some and paint it or what? You have wood hatches here and there so will you prime it all then paint? What's the plan?

Darrell, I've posted several proposed photos of the paint schemes on previous posts, but am always changing my mind. First it was American Beauty, then Obsession. Currently, I am thinking of Hurry Home Honey. The whole plane would be hit with 3M scothbrite, cleaned with Acetone, primed, then painted silver, then OD, invasion stripes, and stars and bars. Spinner might take a while to mask off and paint.

I love the OD color with Yellow Rudder. Bottom of wings are silver with Invasion Stripes.

Still jumping around. Stained the floorboard and primed/painted the sidewalls. Sanded the joint line off the smiley face  intake, primed that area, and sat in position. Installed some plastic keepers for running the air lines and servo leads from the aft end forward. Guess I'll end up using that platform I made for the rudder servo for the Rx mount.

The instrument panel needs to come aft 1/2 inch, but the green paint is still a bit touchy. It's as close as I could find to Zinc Chromate at the hardware store. It's called EDEN by Rustolem.

On final assembly, things will go in a certain order. Forgot something? Well, take it apart and start over. Ha

Whew! I tell ya. Last week I had decided not to do the sliding canopy - too much work. But, this week after seeing the side panels go in I got a new idea on supporting the brass rails for the canopy. Glad I got re-inspired. Still a bit of work to do, but got it engineered and roughed out. I used 90 degree bell cranks to mount the little sliding ball ends onto and it works pretty well. Just hand operated, but that's fine with me. I can open it between flights in the pitt area.

By remaking the seat armor out of balsa, I saved 4 ounces of dead weight behind the CG.

Sequencing inner-main-gear-doors is my last bugaboo to conquer.

Staying hard at it. Made the "bow" behind the seat to help the canopy keep its shape. It's close to scale, but I just did the best I could without any drawings. 3/8" balsa with 1/64" plywood laminated to it with CA.

Lots of small cockpit parts to cut out and fit and then prime/paint. Bought the kit, so might as well do most of it. Got a gunsight too.

Attached the armor to the seat with screws for support. Nothing else to keep it upright. Resin castings behind the seat for show as the full scale had them.

No problem, just use a micro switch on the throttle servo arm so the canopy is opened at idle and closed at 1/4 opened. No wait, you can easily afford a 14 channel radio, you won't even need to eat any cat food.

Made a balsa sheet to fill in the back end of the cockpit area. I will have cut-down versions of the radio and battery that sit back there. Essentially you will just see the tops sticking up. Once again, the cast resin parts are WAY heavy and I will remake them out of balsa. Those two parts, even cut more than half in two, weight 2.15 ounces. That could translate to 4 ounces of lead up front. Balsa will weigh less than an ounce. The main gas tank is below the radio/battery in the full scale, but I'm not going to show it. This is not TOP GUN.

Made a little cover for the aft end of the cockpit. You can get a better view of the radio and battery without the canopy. They will be a bit taller than these resin parts. The tray is hung off the back of the seat armor and one screw on the aft tend of the cockpit.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7725_zpsazcanhrk.jpg)

Painted the seat and armor Zinc Chromate Green. Dropped the seat and took a chunk out of the armor. Touch ups are common. While some may think all the metal parts are Zinc Chromate Green, from photos I have seen the top of the armor and that bow are black or some dark color. Needs some matte clear finish.

Sonny, I looked at the picture of your plane and then took a look at Lane's plane.

It's obvious that he is not really building it; he is just taking a long time with it, and he has a lot of parts and tools in the pictures to make us think so.

I just realized that he has actually found a way to shrink down a real one and make it look like something he built. The government is going to find out about his secret and take him away one of these days.

Steve, I'd use unobtanium for the armor but it's rare, very expensive, weighs zero, and can withstand a 20mm round at point blank range. Sadly, I can only afford balsa for the cost and weight savings.

Had to have a change of scenery. Put the fuselage up and drug out the wing. I am using the same method of lining up the retracts that I saw on RCSB, I forget who did that now, but he had a Corsair. A fellow club member, jack haynes, also suggested this method. Bad news is that the retract hardwood mounts are poorly aligned and require quite a bit of trimming to get the gear aligned. I'm still in that process. The inner gear doors fit good and bad, one side vs the other. Right wing fits great and the left side looks like they came back from a 3 Martini lunch and took up where they left off. I switched from the flimsy aluminum rods for the hinge rods to steel piano wire. The strut covers will require a complete change in hinging as the CARF design just won't work for me.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7935_zpsxcbfvcho.jpg)

Bit of a close up of the temp mounting of the gear. Kinda got an angle of dangle with the mounting blocks to fool with.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7937_zpsso16dyzk.jpg)

Inner gear doors mocked up with steel hinge rods. Will cut them shorter, later.

More mockup of the gear extended.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7942_zpsiy42ge5r.jpg)

Gear down and locked with inner doors closing over the tires. So, basically, the alignment is about right. I cut out those loose parts on the wing to gain access to mount the retracts and will replace them with a new hinge and strips of lithoplate to cover the gaps.

Thanks, Darrell, but this is just the layout. I've already discovered I should have gotten the 7/16" diameter air cylinders for the inner doors vs 5/16" units. The larger air cylinders will give the best shot at pushing the doors open and pulling closed on takeoff speeds. On top of that, the air cylinders/linkage are rather difficult to get installed just right. The strut covers are a pain as well. Jack Haynes is helping me out here, so, I am sure I'll get it done right! And so it goes.
Title: Re: Composite ARF P-51D
Post by: Lane C. on October 18, 2016, 02:49:30 PM
The above photos were just layouts. The real work began in making them work.

First is the inner gear door. Got the air cylinder setup  and it wasn't as hard as I thought, but needed the help of  Jack Haynes to get me going. This air cylinder is a United Precision 5/16" diameter, 2 inch stroke/2-56 rod and Jack suggested changing it out to the larger capacity 7/16" diameter, 2 inch stroke/4-40 rod because there is lots of air pressure on those clamshell doors after takeoff.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_7950_zpsshczalfm.jpg)

Next is the retract for the right side. This was a bear because I've never setup a retract with attached strut covers. Man, took many hours to get it this far with the strut cover in line with the retract .This is still in a mockup stage and will have to go in and make it all for real, but at least got the basics down. It's not as easy as it looks, as most of you know well. I had to cut into the gear mount leading edge side 0.200" to move it into position with the strut cover location. CARF doesn't mention this in their booklet! ha

Got the aileron and flap servos installed per Jack's methods. Seems to be solid and works well. Flap throw is pretty large! That should slow her down on final. Had to cut a 2.25 inch access hole in the wing root to get to the servo wires later. For some reason, Jack's wing is a later model and has several large holes along the wing root. Still waiting on the newer air cylinders for the inner doors - going with the 4-40 actuator rods vs 2-56. The 4-40 cylinder is larger and a bit more powerful.

Doing the one side took a long time, but the other should go quickly.

Came back with more aluminum sheet to cover the holes around the main gear. Pretty much copied Jack's trim pieces. It will look better after paint.

Got the wing on the fuselage for the first time. Seemed to fit fine. I also tested the right wing's retract and inner gear door with the UP-2 air valve. It worked as advertised after some fiddling with the instructions and air lines. Pretty cool to see the door open, gear comes out, and the door closes, all with one flip of the GEAR switch on the tranny. Now to complete the left wing.

I've seen Lee Rice fly on one aileron! His P-40 lost one wire holding it in and he landed OK. That happened to me at a US Scale Masters contest as well. Declared an emergency and landed OK. But, I pretty much needed the wing in place. Ha

Got some more done on the retracts, left side. This side went a lot faster, but it's still a lot of work to fine tune the outer doors on the struts. Both inner doors are in the scale position and clear the tires. Got to make the little aluminum trim piece around the retract cutout and then go to making the aileron and flap servo mounts, and hinging the aileron and flap. I bought some colored air lines from Dream Works for the retracts to make it easier to hook up at the field. Dream Works RC has lots of cool RC goodies if you haven't looked there.

I wondered how to get the hinge wire to stay in the wing. Jack Haynes' method is something like this. Take a small fender washer, solder it to the hinge wire, trim out the end of the aileron or flap with the Dremel tool, push the hinge wire with washer in there, drill a small hole for a sheet metal screw and come down on top of the fender washer. Done. You may want to hit that screw hole with some CA to toughen it up to hold the screw better. But, CAUTION, make sure you have the hinge wire OUT of the aileron or FLAP before using CA - you get it glued in there and you are in a pickle. Take the time to pull the hinge wire out first.

In fact, you could glue a small dowel in there to hold the screw. Not sure how tough that spongy fill material in the aileron is. I am thinking of doing that. Hate to have a hinge wire come loose inflight.

Small fender washer soldered on the hinge wire end. Recess cut in aileron or flap-end to insert the washer.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_8080_zps81kpxsjs.jpg)

Small sheet metal screw to hold the washer in place. I also coat the hinge wire with some light oil before inserting in the aileron and flap - they've been known to rust.

Pretty much done with the wing. Got the air lines and servo leads situated. Color coded to help at the field. Lots of lines to connect.

(http://img.photobucket.com/albums/v228/numskin/planes/IMG_8112_zpssytyqzik.jpg)

Lines are Tee'd off - one line goes out the top of the wing to the UP-2 valve, and the other goes to the opposite wing half.

Other wing half gets the servo leads out the top.

Looking real good, Lane. I can see that 2 wing halves sure complicate/multiply all the line/wire connections. I figured fewer wing air connections with the UP-2 placed in the wing (that's with 1 piece wing).

Post by: Lane C. on November 12, 2016, 01:25:22 PM
Darrell, I suppose you could add the UP-2 valve on the wing somewhere, but I was copying some of the builds on RCSB and they had the valve in the forward fuselage. Oh well, I think it will work either way as long as the air lines are correct.

Built a transport stand for the P-51 today. That styrofoam stand is good for the work shop, but won't handle any travel. 48 x 21 x 16. Scrap wood from building the cabinets. It's too big to grab (and too heavy with the P-51) like my other stands, so I'll get some stamped steel handles and have two on each side so I can get some help loading and unloading at the field.

Finally got all the parts I needed to run the wing all up with air and electrical power. It all worked fine with the UP-2 valve. I must have run the gear 40 times just watching it work as advertised. Pretty cool to see the doors open, hold open, gear goes up or down, and then the doors close. That valve is a neat piece of work. I'm going to run two of the big air bottles like in the photo because it takes a lot of air to run things. I got about 6 gear cycles on the tanks I rigged together, which is about the same as two of the large bottles. I still have the tailwheel to take into the air usage account as well. I just need one good UP cycle and one good DOWN cycle.

Sonny, I have run the gear perhaps 100 times by now. I'd say it's broken in. Ha

I tested the retracts at pressures from 120 down to 45 PSI. At 120 PSI, it's too much on the gear and it locks in the retracted position too hard and when it lets go, it's almost violent. Seems 80-90 PSI is about right, gears and doors work smooth, and all flows nicely. Runs out of air pressure at 45 PSI - gear might come down, but won't go up. Nice to know before getting to the field.

Barry, we might take a look at the inner doors on your P-51. If you weren't using a UP-2 valve, then that would fix it, most likely. But not sure of all the problems you were having with them.

I had one of those stupid electric valves from Aeroworks. A new air valve wound have solved my problem. The other problem was the actuators were not powerful enough to hold the doors shut at wide open throttle.  Barry.                                                                                                                        PS they work very good now.

Hate to say this, but I give you a 50/50 chance of your inner gear doors working.  The fellow that built may P51 was Brian Young, you can find him out there with a 120 inch P47 on some youtube videos.  Anyways he said he had to go thru about 5 different set ups to get the doors to come up and stay up.   He ended up using some pretty good size 3/8 inch cylinders really cocked at a highly dynamic angle to keep the doors shut when the bird was going 70 or 80 MPH.  One of the cylinders gave out and I set a system up a situation that looks about like yours and it did not work.  I took the inner doors off at the field, and just flew.  I need to spend some time working on the bird since it is such a great flier, and so stable.  I need to set something up like he had.   The fulcrum was about 1.75 inches out from the hinge.

Oh, oh. When you have a 50/50 chance of something not working, if it is on an aircraft, that means it has a 90% chance of not working. Unless of course, it can cause major damage, in that case it has a 99.9% chance of not working.

Hi Doc Bill, you've been silent here too long! ha

I copied my doors after Jack Haynes' setup and his works fine.  Same air cylinders, same location, same UP-2 valve. So, I'd say that the chances are it's going to work, but nothing is guaranteed in the air! We'll see when she flies. Like you say, if they don't work, I can take the doors off, block off the air lines, and fly.

If it turns out they won't work, then I can live without them as I almost left them off to start with! ha

Been working steadily on things. Got the PSA exhaust kit installed, partially anyway, and glued on the smiley face to the belly radiator. Used Hysol on the resin manifold castings to keep vibration from popping them off. Still have the brass headers to jazz-up and make like real welded-up parts.

I'm getting close to doing a full-up CG test when I get the whole plane assembled like it flies. I have all the air lines routed, servo leads run to the Rx, gas tank mounted, and wing halves done. All I need to do is get all the cockpit parts and canopy back in, hang the engine, and get some help to man-handle the old girl on and off the Vic RC CG machine. This should weigh-in at about 32-34 pounds without paint, but I'll try to get an actual all-up weight at the same time.

Did the CG and weigh-in today. Barry came out and helped my wrestle the big girl around. This is as big a RC plane as I ever want! haha

Model weighs 36.5 pounds.

CG as she sat is forward of 25 percent MAC. Not sure what that number is, but too far forward regardless. To get to 30 percent MAC I still needed 1 pound of lead on the horizontal tail to make 37.5 pounds total. Not a desirable number either, before paint.

Not much I can do on the weight, except I can move the Electro Dynamic batteries aft of the cockpit. Right now they are ahead of the wing a bit. They are easily moved. I might be able to keep the weight at 36.5 lbs by shifting them aft.

With paint, she'll be closer to 40 pounds, which isn't too much for the P-51 being the size she is. I think the heavy laminated engine mount is part of the weight problem, plus the extra glassing I did under the engine area and in the belly area for a potential dead-stick, gear-up landing. I was hoping for closer to 30 pounds, but she is what she is. Now, all to do is paint the old girl which I will do next April or May.

Post by: DocBill on December 17, 2016, 04:44:57 PM
Yes, it amazing, how well you try to build, and plan, things come together, and then you have to modify.  You need to add weight to your tail.  You might want to fly the bird a little nose heavy at first and  assess the flight characteristics.  I would not necessarily bring the CG to exactly on spot, leave er a little nose heavy.  And then on the other hand I had to add 9 pounds to the front of the Corsair.  It is all a little different from plane to plane.  Have to agree, the 100 inch 35 to 40 pound P51 is as big as you want to go.  The corsair weighs in at 49 pounds and at 110 inches is just too much.

Post by: Lane C. on December 17, 2016, 10:20:48 PM
Doc Bill, by the time I move the 3 batts aft of the cockpit area and paint the tail end (usually a bit heavy on the paint), she will be close to 30 percent MAC - certainly between 25 and 30 percent. That's flyable. Adding lead to the tail isn't my first choice, unless I tuck just a few ounces under the horizontal tail along the fuselage to fine tune the CG.

My plane is not painted.  It is the factory aluminum color of the building material.  I have not weighed it.  And at 18 degrees today, my body parts are not big enough nor strong enough to put the plane together and weigh it. !!!!!!!!!   I need to get er up in the air.  Once I was flying the P51 and a kid was like, " Wow dad look at that big plane it must be soooo hard to fly."   This was/is one of the easiest planes to fly,  it flies like a trainer.  Just put the nose down to land and flare at about 9 inches.  The plane really wants to float.  But, I do not think that my plane is anywhere close to 40 pounds.  I can do the maiden for you.  hee heee hee.  I did the maiden on my P51 and Corsair.  The Corsair was really cool.  I put so much work in to that puppy [ the corsair ].  She only needed one click of down to trim er out.  That was a nice day.  I remember all the guys helping me and that was so nice to see so many guys chip in and help.  Was a great day.  We even have a video of it.  I got really sick around Thanksgiving, so when it was warm out I could not make it to the field.  Now it looks like mother nature has come to bring these nice temps in the teens.  Yikes.  Let me know if you need help, I am not that far away.  Bill

Thanks for the offer to help, Doc Bill. Fell free to drop by and check out the plane. I will be moving her into the house after I make these CG changes so I can work on another job for one of the club members. She'll stay inside till April or so when I can paint.

16 Deg F at 8:30am this morning; coldest I remember in about 30 years. Dang cold. Parallax error makes it look like 17 deg F.

This will be the third use of this spot behind the cockpit. First it was going to be the rudder platform, then I just used one servo for the tailwheel and rudder. Next, it was the platform for the Rx. Now, it's the platform for the E.D. A123 batteries. The batts and mounting board weigh 1 lb 5 ounces which will offset the nose heavy condition, and coupled with painting the tail end, should bring me up to 30 percent MAC. I had already made this a fairly solid place with heavy beams epoxied in place on the sides of the fuselage, plenty strong to carry the batts.

Back on the job today. The glare shield had to be painted before the wind screen could be glued on. So, did that and epoxied the screen on with 30 minute. Once dried, I will removed the screws and fill with Bondo as well as the gaps between the screen and the fuselage. Go a few things to do on the fuselage and then I can begin spraying 301 primer.

Yes, its good to see you back on the boards. I look forward to seeing your new Stang at the field.

My new Blondie P-51 is ready for her first engine run. I hear, from RCU, that the 70cc Torque Pro engine is prone to overheating in the mustang. I sure hope that is not the case.

Sonny, hope you have good cooling luck on the P-51. It should hum right along with a 70CC.

I have the fuselage lightly scuffed up and most of the little holes here and there filled in with Bondo. Seems like every time I look at her, there's another hole I missed. Ha Other than masking off, I could primer soon. By holes, I mean small screw holes I was going to use, but changed plans and now they are not needed. Stuff like that.

Got some test painting done on Sat. Took the composite canopy frame waste part and used it for a test bed on the English Color 301 Primer and Behr Latex paints. The primer went on very slick and dried immediately as Lee Rice told me it would. The latex colors went on very nicely after a light sanding and wipe-down of the primer.  The Yellow and Green Mil Spec Colors are right on the money, but the "Aluminum" color was a dud as Home Depot really cannot duplicate a metallic color with computer matching. I will have to find some paint other than latex such as Silver Butyrate Dope or possibility a custom automotive single stage paint match from English Color.

Behr latex paints and color scheme. Lady Jane (in photo) and Hurry Honey Honey are the same paint jobs, just different tail numbers and call signs. By the way, these are the current flying paint schemes. The WWII versions had OD Green rudders. Not sure why the change to yellow, but I like it as it gives and extra measure of visibility.

Two out of three paints are good.

Aluminum paint was a dud. Looks like a blue grey.

Primered the right wing with 301 primer from English Color. Works very nicely. Dries quickly and sands easy. I used 280 dry paper to keep the sanding a bit rough for the paint to adhere to. That's it until the finish color.

Shot the aluminum color on today. After it dried, took some 0000 steel wool and gave it some detail. Most of the bottom of the wing will be invasion stripes, so much of this burnishing won't be seen.

Thanks, Darrell. As nice as the latex invasion stripes look, that aluminum Urethane paint is very cool. Dries hard as a rock. A little bit dangerous to use, but you have to be fully aware of the proper safety mask use. I even bought a disposable jump suit to keep the vapors off my clothing. Wouldn't want to use it very day, but man, it's nice stuff.

I am going to hit the stripes with some water base Poly Clear Matte finish to keep it from scuffing.

I tried another OD Green that had no Mil Spec number. It's supposed to be an accurate WWII OD Green. That's the WWII green above the aluminum color. I think it looks more the part.

Cool stuff. Masters at work.   Barry.                                                     
Ps. I will be flying again as soon as I can. My radio is on the the way back from Hitec. They found that it needed the firmware updates. That alone probably didn't cause the loss of signal but it didn't help either. They want me to rebind everything in scan function. That will help it get the cleanest channels. All the airplanes were bound in normal mode. The scan function is for crowded areas such as our field is getting to be. Probably going to test in my foamy jet first.  Ha.

I think you have about 2,700 hours of work on this plane and you are only about 20% finished. How can the company call it an ARF? Oh wait, I thought ARF meant ALMOST Ready to Fly, for this one it means AIN'T hardly Ready to Fly.

Got my paint masks in today. Not much to look at, but they go in a sequence. For the stars and bars (S&B), the full pattern of the S&B outline mask is laid down and painted white. Then, the S&B mask is laid down in place and the Dark Blue is painted over that, while leaving the first paint mask in place. When you pull the masks up, you have a blue and white S&B. I'll try to stop and take a pic in the process.

With all this rain, I haven't gotten much done lately. Tuesday looks like it will be a good sunny day.

Wow, this explains why your paint jobs are much more accurate than mine and you lines are so sharp. Now I know that my practice of using a glove on my hand, to keep the paint off my hand, is just not hacking it for masking off nice nice sharp edges.

Steve, amazing how fast they cranked stuff out for WWII. Do ya think they knew it was coming before hand? I sorta do.

I may pray for another BIG storm to flood the field again to give me more time to paint before the scale meet. I think I can have it ready to fly by mid August. Maybe that's TWO floods or ONE FLOOD of the NOAH type.

But, I made MORE progress today, I laid out the paint line for the Shade 41 on the upper fuselage. Took a while to arrive at the right angle-of-dangle. I tell ya, applying tape is the hardest dang part of painting.

You may need to put floats on the Stang.

Do you use a laser to guide you when you put on the tape?

Looking good, seems like you're getting a little faster.

No laser, just a MK 1 calibrated eyeball. Getting faster. Coming back to me after 3 years.

Got the plane masked off this morning and shot the Shade 41 OD Green. Took 6 fine coats with heat gun drying in between coats. After that, let it dry several more hours and put on 2 thin coats of Polycryllic clear matte.

Maybe the rudder next. Haven't done any yellow yet.

On the subject of yellow: since this 'color' doesn't have any real pigment are you going to do some white priming prior to shooting the yellow? That worked good on the P-47 yellow stripes. Mustang sure looking good.

Spent about 8 hours in the shop today doing paint work. Long day.

I call this my Texas Autoclave for paint curing. Ha. With the tailgate up and camper door closed, it got to around 115 Deg F. Kept the fuselage in there several hours to bake that upper Shade 41 paint on. That's a temp gage on the tail end.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_8918_zpssaupdeuu.jpg)

Got the rudder detached and painted it Yellow. About 4 coats over the Urethane Aluminum paint.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_8927_zpsl1eeyeoc.jpg)

Some small parts got the Shade 41 as the fuselage. Spinner got the Urethane aluminum over the 301 primer.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_8930_zpsgwmled98.jpg)

Overall side view. Looks pretty scale. Not perfect, but not bad. Leaving the masking on the canopy till I can put some clear coat on it.

Hi Darrell, Ha, the autoclave gets just hot enough to be warm, but not dangerously warm.

I considered the White under Yellow option, but then I remembered I did a spray test on the colors first thing and the Yellow over grey primer came out nicely, so, just went with Yellow over the Aluminum color Urethane paint.

Back on the job today. Got a paint mask marking done and it turned out better than I expected, which is good, because this is not a good place to do a test run! haha.


(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_8980_zpsn66vhn8n.jpg)

Using masks begins with putting down the overall outline and then painting inside of that with white paint. I left out the white paint photo.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_8976_zpsjjqxvbeh.jpg)

Next, the star and bar mask is placed centered in the bigger outline. Then a dust coat of insignia blue is made to seal the edges of the mask. Paint layers are built up and the color deepens to a dark blue.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_8977_zpsdnh6zubs.jpg)

Then, pull the star and bar masks off to reveal the clean white areas. Pull the remaining mask off and you are done.

Doing some of the smaller details on the fuselage while I am waiting on replacement masks for the tail numbers and HHH script markings on the cowl. Did the OD Green Shade 41 on the wing fillets like the prototype. I use old towels to save time on masking large areas.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_8999_zpshgvqevxp.jpg)

After an hour's layout and masking, I get the fillets painted Shade 41. Will let them dry several hours or maybe overnight and hit them with some Polycryllic clear coat. I go thru LOTS of tape!

One tip I will give, since the colored masking tape is quite a bit more $$$ than plain no name brand vanilla tape, I use the colored tape on areas where I am putting tape down directly on the surface of the model. If I am just taping down over one piece of brown paper to brown paper, I use the cheaper vanilla color tape as it's only a few $$$$ per roll vs twice that for the Blue, Yellow, and Green tapes. The vanilla tape REALLY grabs hold and will likely pull the paint off or leave a sticky skid mark on the plane's surface which takes denatured alcohol or light sanding to remove. So, use your tapes according to the job at hand.

I laid the line out with a large French curve I made years ago. Taped it off with some 3M vinyl 1/4" tape from English Color. I was able to hold the right wing up to the fillet while snapping a photo. Seems to match up to the full scale HHH.

Did a test today on the paint mask that's too large for the model. Callie is re-making it to size. I put it on the paint test bed to see how hard it was going to be to get the two masks properly aligned. And it was tough. First coat is Yellow and then the 2nd mask goes on and Red is added. But getting the mask in place is tough because you cannot see thru the mask material. Got lucky I guess I will say. Glad the script is only on the left side, not both.

Other than that, primed the left wing with 301 English Color primer. Needs sanding tomorrow. This is a high-build primer for auto work, but works nicely for planes. Got plenty of pics of all this on the right wing, previously.

Started the checkerboard nose trim. Base color of Yellow. Now comes the hard part - adding the Red checks. Not sure how this is gonna turn out. Letting the paint dry several days before any more work on this.

Well, decided to take on the checkerboards today, head to head combat. Lee Rice told me he just starts masking off and going after it. So, that's what I did. Tired of wondering how to make it perfect, and just faced it head-on.

Masked off the entire yellow base color, divided it in two parts forward and aft, then laid out the checkers. Then, cut out the parts on the lines and pulled up all the tape that was covering the soon-to-be RED areas. Marked 'em before hand to make sure I got things right. Odd thing is that the two parts are not exactly split in two, but the aft one is slightly less than half the width than the forward part.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9059_zps2tyvazmo.jpg)

After the above, masked off the rest of the plane, then hit it with light mist coats of red Fu-Fu-Can (Ed Couch's name for rattle can paint).

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9063_zpsgmnfvtq8.jpg)


Pulled off the tape and voila, instant checker boards. Like most dreaded things, it wasn't as hard as imagined. But, one has to put lots of thought into it before diving in.

Her sexy tail up and looking good.

Got in too much hurry to paint the spinner. Painted on the yellow middle color and waited a few hours to dry. Then masked off the Yellow to paint the Red upper and lower. Bad move. Yellow was still not dry under the surface. So, sanded it all down and started over. Won't be in such a hurry next try.

While it appears the spinner is just sitting on a table outside, it is really in the baking oven! Been out there all day in the Texas Sun. Will put it out again tomorrow. That yellow needs to be very dried before I mask it off again for the Red.

Thanks Darrell.

Gotta have kill marks! This is the last set of paint masks I have. There are 3 of them. First is the white circle. Next, a "blanker" is inserted into each opening and sprayed black which leaves the small black outline inside the white circle. Next, after drying overnight, the "iron cross" (3rd) paint mask is laid down over the circles and sprayed black.

Two months to paint! That may explain why your models look way better than mine. I guess four hours is just not long enough to get that realistic paint job.

Did some detail work on the radio and battery behind the seat.  Radio had 3 wires coming out of it and the battery had 2 wires. Got some scrap wires and loom and threw something together. Not bad. This layout is fairly scale as far as where the wires come out of the components and go down into the fuselage. these parts were included in the cockpit kit and were made out of cast resin. Resin is VERY HEAVY. So, I simply duplicated the same parts out of balsa and they weigh almost nothing. Same for the armor plate right behind the seat - remade it out of lightweight balsa.

Also began programming the new Spektrum DX-18 Tx for the control surfaces. Got the Rudder, Ailerons, Flaps, and Elevators working. The DX-18 is pretty complicated and has more functions than I'll ever use.

Got a setback. The engine has some metal flakes in the upper cylinder area. Not sure, but they look like aluminum flakes. Will have to get this looked at before any more assembly. So, depending on how it gets handled, might be FALL before I get it back together! haha. Well, that avoids test flying in 110 Degree F August heat!

The MVVS engine factory is in CZ, Europe. Great. So much for quick turnarounds.

I looked in the exhaust port and saw them. Ha

I haven't looked in the crankcase. To take the head off means I will need a new gasket. I think parts for the MVVS engines come from CZ. I sent an E-Mail to MVVS to ask where their service center is in the USA. If not one here, then I need to send it to MVVS. I really don't want to do this myself.

I wonder what happened to the quality control for them to have chips in the engine. That is actually hard to do during the manufacturing and assembly process without being noticed.

All of their engines are also supposed to have been run for an hour. Seems like the chips would have scored the piston and cylinder walls during the running.

An inside view of a gas engine. Decided to do the clean up on the engine myself. Popped off the cylinder and gave it a cleaning. It all looked good under the piston so will get a new gasket or make one, and reassemble it. I felt it would take at least a month to send it to MVVS in Czechoslovakia and they'd do the same thing I did. Also, checked out the guy that Steve mentioned and he doesn't work on MVVS engines. Kinda outta options here. So, did it myself.

Always balance your spinner. An unbalanced spinner can create small to large vibrations which can lead to serious problems with your model.

Balance your props independent of the spinner.

Most spinners will require a larger/wider setup than a prop. Take a board and drill the holes to fit your balancer. Get a 1/8" steel rod (rigid piano wire) about 12" to 18" long to handle the spinner. Or, get whatever rod to match your balancer. Add a level to make sure it's going to be true. This is the High Point Balancer. As far as I know, Ed Couch and I are the only ones on Earth who own one.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9186_zpstuoyuz6w.jpg)

Make index marks on the backing plate and cone to be able to keep your balancing points consistent. Otherwise, you will be chasing your tail trying to balance. Yes, you can use a pencil or magic marker, but after a few flights you will lose those marks and have no idea how the cone and backplate were mated to balance. These marks are small but are permanent as I made them with a vibro-engraver. A little red paint touch-up and they become invisible.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9184_zpszg2bhuoy.jpg)

Find the heavy point and mark it. Draw a line from there thru the center of the backing plate. Keep your lightening holes on this line. Drill small amounts at a time, reassemble, and keep going till you get zero movement no matter where on the circle you place the spinner. Don't drill the holes thru the backplate as this creates a mess on the other side you need to smooth off, no need for that. When you paint a spinner like this one, you will likely have to remove quite a bit of spinner backplate to offset the paint buildup. Like figuring CG, it takes what it takes to balance out. Yes, this looks like a lot of holes, but that's what it took to balance in any position. This took about an hour to complete. But, it's time well spent on the success of your maiden and subsequent flights.

Gave up on getting a gasket from MVVS in Europe. Bought some gasket material from the auto store along with some anaerobic sealant. Gasket wasn't hard to make. Got it cut, glued, and screwed. The excess material has been trimmed after I set the engine out in the heat for several hours to cure the sealant. Hope it holds up!

This sealant can be used to make a gasket or use with a replacement gasket, either way. I used gasket material to keep some spacing on the cylinder jug. Sealant by itself in this position might squish down to nothing and cause some clearance problems with the piston or increase the compression ratio, etc.

I can start to install the engine after I hook up the muffler. Yahoo.

This engine looks like it does not have any gasket material. They may have stopped using them to save money. This is the 80cc gas MVVS engine.

I think your fix with the gasket material with the sealant will work great.
Title: Re: Hurry Home Honey CARF P-51D
Post by: Lane C. on July 26, 2017, 11:12:07 PM
Steve, maybe the newer ones dropped the gasket. But mine had one and black sealant as well. I think it will hold up OK. I installed the muffler today with a black silicone 650 Deg F rated gasket compound, loctite on the nuts that hold it on. As soon as I get some new yellow gas line I can put the engine back in the bird. The engine is about the last item now as far as building. Next is the CG check, then engine runs, then flying. With this heat, not in a big hurry to get out to the field with her. Bad time of year for a maiden voyage.

Took a couple of pics to show the engine ready to go.

Kinda looks like never been apart!

Still getting a few bugs worked out. The UP-2 valve that controls the retracts had been sitting with the P-51 while I worked other projects and dried out internally. I did a full-up assembly the other day to test everything and the inner gear doors failed to open on gear retraction. Not good as the main gear come down on the rather fragile inner  clamshell doors. Talked to the guy who makes these valves and he said to take the UP-2 apart and regrease the internals with silicone grease. I did that and now it works perfect. Had a few problems setting up the new DX-18 radio as it's very complex. But, got those bugs worked out as well. Not sure when I will bring it out to the field for engine runs, due to the heat. May be sometime in Sept.

What? No photos? Simply weird. I forgot to get the camera when I took the UP-2 valve apart. Dang.

Since I am not opening the holes in the air intake panel on the lower cowl, I ordered some paint masks for them to give them some life. Pretty simple paint job. Used the Paasche H5 air brush and Behr flat black house paint. Next, I'll give them some flat clear coat.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9255_zpsjp27u9ss.jpg)

Paint mask is positioned on the cowl and then masked off all around. Since I used the airbrush, no need to mask-off the entire plane; I just threw an old towel over it.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9258_zpsbqvcdadp.jpg)

Add the black paint in light coats.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9261_zps4n4uxxts.jpg)

Finally remove the masking paper down to the paint mask. After using the heat gun on the paint, the mask is carefully peeled off.

(http://img.photobucket.com/albums/v228/numskin/planes/Planes%202/IMG_9263_zpsjesmtco9.jpg)

That was pretty much the last paint job. Ha. Gotta get Barry over to help me CG it. I weighed it piece by piece and I estimate it will be 38.5 lbs dry - wing = 12.5 lbs and fuselage = 26 lbs. So, that's about 2 lbs paint added. Anything under 40 lbs sounds good to me.

Decided that was a bit over the top, and wiped it off to do again. I didn't get the arc that the exhaust makes quite right. Not bad, but since I can start over, I will.

Well, maybe, but I keep trying till I get it right or close to it. Problem with the first try was the airflow pattern. This one is pretty close to photos I have. Although, the first one looked pretty cool to me, I was a bit heavy on the light brown exhaust on the manifold itself. That really doesn't start till about the end of the manifold, and it doesn't really get on the manifold itself.

I see what you're trying to do with that exhaust paint. You can't fool me.

You're trying to cover up the fact that HHH got credit for shooting down a flying saucer during WWII.

Here is the actual untouched photo that shows that a flying saucer kill was recorded on the plane.
Title: Re: Hurry Home Honey CARF P-51D
Post by: Lane C. on August 13, 2017, 10:32:57 PM
That's right! Actually, I am covering up the kill marks that are spaced too far apart. Told the paint mask maker and she's changing them, but too late, I already had them painted. Ha

Still not wild about the exhaust stains. Almost cartoonish. But, they give it a real sense of speed. For a non-artist, not too bad. But a real artist would have made them semi-transparent.

That's the WWII version of HHH you came up with, Steve. The current version is what I modeled upon.

Might be getting close to the final go-round on the exhaust stains. Guys on RCSB keep telling me it should be almost transparent. So, wiped it down once again, started with a very light black pass, eliminated the brown, then added the off-white. After that, hit it with a 3M Scotch Brite pad to soften it down a bit.

I thought it looked a little dark, I just thought you may have had some major engine trouble.

Steve, here's the right side. Now, I can focus on the CG today. Will assemble and Barry's coming over to help me flip the ole 38 pound girl over on her gear.

Barry came over and helped me CG the girl today. She balanced at 29 percent MAC and we added no weight. She started to fall thru at 30 percent MAC. After that, we carried her outside for some photos on the lawn. I am happy with the results.

Looks fantastic!

You need to fire up the engine and get it up to altitude before that pilot melts with all that leather on.

Nancy Abby took lots of great photos at the Big Bird Meet 2017. I especially like this one of HHH.

Barry flew HHH today on her maiden voyage. All went well, but need less prop. The 26 x 10 was  too much and needs a 24x10. Couldn't get more that 6000 RPM and that was not enough to really make a great flight. Barry flew a couple of circuits and got her trimmed out, then landed with half flaps. He kept the gear down for the short flight. But, the CG was on the money and she handled fine on all the flight controls. Barry added 5 clicks of down trim and 3 clicks of left. Not bad for a 38 pound warbird on the first flight!

I'll get a couple of new props to test out and run her on the test stand again before flying. I'm looking for 6300 to 6500 RPM.

Now, got that milestone out of the way and can enjoy flying her.

Photo of Happy Barry after the flight. He's happy the engine stayed running! And so am I! Ha

Yes. I'm very glad the engine ran good the 26/10 was to much for the 80cc.  Hopefully the prop change will do the trick. We couldn't do a real shake down flight with the engine putting out marginal thrust.  So I left the gear down and trimmed her up. I then made a couple of nice passes and landed her. There we're no surprises she lands very nice like a big Mustang should.  I'm sure if the engine will not do the job Lane will put a DA 85 in her. We can't have a big nice Mustang just lumbering around the field. Ha.  Barry

Darrell, bought some props that are not as big as the 26x10. Got a 23x10, 24x8, and 24x10. Maybe one of these will spin up to the mid 6000's or better! Maybe this heat will go away too.

My Dizzy 80 works best with a 24x12 or a 24x10.  Think the 24 x 12 is better.

Post by: Lane C. on September 24, 2017, 09:44:00 PM
Doc Bill, we'll test them all. After the engine breaks in some, might be able to swing the 26x10. But as long as we can get some good RPM's out of one of the other props, that will work. If the 26x10 doesn't work on the 80cc, then it will work on the Zero/DA-100.

Got the P-51 out to the field on Sunday. Ran the 24x10 prop first. It turned 6950 RPM right off the bat. Wow, never expected that much more RPM. But, the vibration of the engine killed the retract servo and commanded the gear to retract. We caught it before it totally collapsed. I won't be using mini servos up front any more. I replaced it with a full sized metal gear hi-torque servo. So, next time out, might get another flight in.

The other day when about to fly my Top Flite P-47, the Red Wing gas tank had a malfunction. Seems the parts inside the tank had come loose. Red Wing had a neat idea on their tanks, but failed to properly secure the vent and fill lines inside their tanks. The vent line came off and forced me to shut down flying for the day. Now, to the P-51 thread. I also installed the same 32 oz tank in the P-51 Hurry Home Honey. Due to the rather lengthy build and cost, I am pulling the Red Wing tank out and going with a tank setup that Barry suggested. On taking the tank apart, the same thing happened to this tank - the vent and fill lines just fell out.  Wow! Could have been a disaster! PSP Manufacturing makes a special aluminum cap that fits a one liter Fiji water bottle. They also make the vent and fill fittings as well as a special clunk just for that bottle. I ordered the kit and bought a bottle of Fiji water at the local gas/convenience store. PSP has a video on YouTube that show how to do the conversion. Pretty simple. I pulled the Red Wing tank out and placed the Fiji bottle in the P-51. Just so happens it fits perfect. I thought for a while it would take some serious rework but appears not. I'll show a few pics as I make the change. Got one pic below of the new bottle in place without any fittings. You can see why I was concerned about the fit. I made some special plywood brackets to hold the tank from the top of the fuselage. A Dubro tank just wouldn't fit. I also did some conversion on 32 oz vs 1 liter. Turns out that 1 liter = 33.81 oz, so with the small void at the top of the tank with the vent line installed, the actual volume will be about 32 oz of usable fuel. Every little bit helps when running an 80cc engine (the 32 oz Dubro likely would only give 30 oz usable fuel). Two more oz of gas is enough to be a life saver!

Steve, "crash" would cover it! ha. Engine quit on landing approach. It happens.

Why hang it up just because the engine quit on landing? I've had many dead-stick landings and just started the engine back up and continued to fly.

Hi Steve, well, it's the wings. Pretty much toast. CARF's composite material is meant to fly, not crash. Nothing like a built up wing that's been glassed. New wings parts and canopy, etc, are at least $1200. Put enough money into this build anyway. She's happy in the shop keeping watch over other new planes in the hatchery. Ha

Had some company recently and they helped me rehang the P-51 in the living room. She looks bigger in there than the shop. But, I like her there.
