Default Warbird Build Contest, 2010 - Mountain Models / Laser Arts P-51

First let me state that I’m an inexperienced builder and pilot and joining a build contest was something I never thought of. But Watt the heck, I like to build too. I started on a Mountain Models Dandy just over a year ago. I have progressed far, but I still have a long way to go compared to most of the builders here. Due to my inexperience, I thought that a kit would be a better start for me and I have always wanted to build this model. The contest just gave me an excuse to build another plane. Thank you Rabbitcreekok! Time is at a premium right now, so this will be a slow (but steady?) build.

Here is some information on this kit:

Specifications:
Scale: 1/12
Wingspan: 37 in
Length: 32.7 in.
Wing Area: 254 sq in
Weight: 15.5 - 19.5 oz
Loading: 8.8 - 11.0 oz/sq ft

The details can be found on the Mountain Models web site:
http://www.mountainmodels.com/produc...roducts_id=201


I am aiming for a nice “Park Flyer” type plane. Not a rocket, but good performance. I’d like it as light as I can get it without sacrificing strength. Just staying under 20 oz AUW is my target.

I plan to use the following components for my build:

Motor: EMax 2215/25 950 KV 180+ Watts. (The specs are all over the map for this motor and the EMax web site does not give much info.)
ESC: PowerUp 20 Amp from HeadsUpRc.com
Receiver: Spektrum AR6110. (Reused from existing planes)
Servos: 4 SG90E TowerPro from HeadsUpRc.com
Retract Servo: HXT900, A spare purchased when I bought my EVA components.
Eflite Brushless Stick Mount.from MyAtomic.com
Dubro 2 in Spinner from MyAtomic.com
Retracts: GWRGP003 (GW-RG-MMN)
Covering: Solite and/or Coverite Microlite
Planned Battery: Turnigy 1300 mA 3S

So far the total spent for the model and components is about $150. I am reusing a receiver and batteries and some of the covering was purchased much earlier, so that helps.

I am getting EMax Motor number 2. The first had some odd behavior and I am exchanging it with the reseller. (To be nameless until I get the second one in and tested…)

There are a couple of things that I have never done before that will be used on this model. Pull-pull controls on the elevator and rudder and landing gear retracts. Wish me luck on these!

There is already a nice build thread of this kit by Gnascher here on Wattflyer.
http://www.wattflyer.com/forums/showthread.php?t=26844

There is a huge build thread over on RCGroups.com that contains a lot of information as well.

I have not decided on a color scheme yet. The ones I like are the ones that Parkzone used for their P-51s. Green and Silver. I also like the looks of the Red Tails on the P-51s flown by the Tuskegee Airmen.

Default P-51 History

Here’s some good background info from Wikipedia.

Originally Posted by Wikipedia
The North American Aviation P-51 Mustang was a long-range single-seat World War II fighter aircraft. Designed and built in just 117 days, the Mustang first flew in Royal Air Force (RAF) service as a fighter-bomber and reconnaissance aircraft before conversion to a bomber escort, employed in raids over Germany, helping ensure Allied air superiority from early 1944.[2] The P-51 was in service with Allied air forces in Europe and also saw limited service against the Japanese in the Pacific War. The Mustang began the Korean War as the United Nations' main fighter, but was relegated to a ground attack role when superseded by jet fighters early in the conflict. Nevertheless, it remained in service with some air forces until the early 1980s.
As well as being economical to produce, the Mustang was a fast, well-made, and highly durable aircraft. The definitive version, the P-51D, was powered by the Packard V-1650, a two-stage two-speed supercharged version of the legendary Rolls-Royce Merlin engine, and was armed with six .50 caliber (12.7 mm) M2 Browning machine guns.
After World War II and the Korean War, many Mustangs were converted for civilian use, especially air racing. The Mustang's reputation was such that, in the mid-1960s, Ford Motor Company's Designer John Najjar proposed a new youth-oriented coupe automobile be named after the fighter.[nb 1]
http://en.wikipedia.org/wiki/P-51_Mustang

YouTube has documentation on P-51 Dogfights

Tuskegee Airmen 1995 HBO Special Is good too.

I also found good information on this site.

Steve,

This kit is outstanding. You will have a blast building and flying it. I posted a short build thread on here last year that you might find useful. There's also a video of my maiden flight on there too. It flies like a charm, still flying mine.

Here's the link if you're interested:

http://www.wattflyer.com/forums/showthread.php?t=45032

Good luck with yours!

I may just have to enter a new build myself. I have a HOB FW109 in the box that is itching for some build time.

Nice choice Steve. If I build another, I'd build the MM kit. The black Cisco scheme in their ad caught my attention, as it looks really good on the kit. I built a larger HOB kit, but it's not close to scale. Someday I'll have to build this scale kit.

Default Opened the Kit Tonight

All,

Thanks for the encouragement. BillG, I’ll pretty sure the P-51 kit on the Mountain Models site is actually covered in Green Solite, not black. Green Solite is very dark. Forge, sorry I missed posting a link to your build thread. I am really happy that yours became such good flying kit. That’s exactly what I am aiming for. I do remember reading your thread when you first created it; I think that’s why I have always wanted this kit.

I did open the kit tonight and really inspect the contents. The kit seems great. The balsa is very light and cut great. The simple way of taping all of the balsa to cardboard keeps everything safe. I just need to be careful now that I’ve pulled the balsa out so the cut parts don’t fall out. The plastic formed parts are all in very good shape. Somehow I didn’t put the vacuum formed cowl and spinner in the picture of parts. Sorry about that. It really is in the kit. I did not open the bag of hardware and small parts yet. I’m afraid of losing something! The Mountain Models kits are kind of like 3D puzzles. Most of the building will not take place on the plans, but just by assembling the pieces in space.

One more thing I forgot to mention was that I purchased this kit from Brian personally at the Toledo Weak Signals RC show. It was great to actually meet him.

Steve

Yeah it's a tinge of green tint, but black would look good though.
Retracts will be a nice touch. I assume the grey retracts are the same as the GWS blue, but just different in color. There obviously much stronger than the Picos, and the only issue I've had with them is the main struts turning on me. I believe I had retapped one for a different set screw once, to hold in place. I'd almost be tempted to use the GP10 retracts, but they are heavier
.
The cocpit molding looks really nice and detailed. I'd be tempted to cut it even deeper for a full cocpit, as see if the gear could be arranged around it. Gotta love pilots with a bit more than just a head in quicksand.

Glad to see someone do a current build on this one,I'm thinking about building one later this year,good luck!

When I fly alone, I prefer to be by myself.

Default Fuselage is about 90% complete!

I plan on building a stock plane, so no real mods are planed. I will make some small mods if people suggest changes for strength and/or flyability concerns.

I worked on the fuselage this weekend. It’s a simple build. Just follow the instructions! I am using thin and thick CA glue as recommended. I did notice that my full size plans don’t quite match the parts. The plans say version 1.0 and my guess is that Brian of MM made a change. Everything still fits, just that the end part of the fuselage is actually bigger than what the plans show and the parts that it joins to were shortened to keep the overall length correct. This puzzled me at first while I was building the fuselage sides and the main top piece was shorter than the plan, but when I pulled out the end piece it all made sense.

It’s a fun quick build. 1st you build up the sides, then a some of the formers and a large center section piece. You then dry build most of the fuselage. This way the kit basically self aligns and stays straight. When everything is together and fitted nice and straight, then you glue. I did have one mishap. I broke the F-10 former when trying to glue while squeezing the parts together. It’s already repaired and as good as new!

I am on step 20 of the fuselage plans, creating the sheeting. Only 8 more easy steps to go, then the fuselage is complete. Not bad for only 2+ hours of work. It feels like building a 3D puzzle to me!

Steve

Looks good. About the parts not matching the plans, I've noticed that on a few kits before, just make them fit

Looking good Steve.

Been looking at the MM kits for a bit now and seeing these builds on them makes me even more interested now.

Offtom, I have been very pleased with the MM kits I have. The have been pretty easy to build and fly great. You can't ask for anything more.

I just switched my EVA back to the sport wing. It's such a nice, relaxing flying plane compared to using the biplane wings. It can fly real slow and can be flown hands off for extended periods of time, but it's still pretty acrobatic if you want to push it. I switched wings so I can fly off my club's grass field. I can easily take off, but landings are still a problem. It's the biggest plane I have and I find it easier to fly with the big gas planes at the club than anything else I have.

Steve

Default Fuselage 99% Complete!

I have not had much time to work on the P-51 this week, but I did manage to finish the fuselage. The sheeting was difficult to get to lay totally flat. I did an initial water spray and wrap with rubber bands then let it dry over night just to get the correct shape. (No glue yet.) I trimmed the pieces to fit, then I spayed the outside only and used some odorless CA to attach it. The odorless CA takes 15 to 20 seconds before it sets up so I had a little time to get the part where I wanted it. I did the front sheeting in 3 phases. 1st was to glue just the center down. Then one of the sides, then the other. I really needed to wet it a lot to try and get all of the sheeting flat against the formers. I held it tight with both hands until it setup. I got it flat but some of it was not straight all of the way. I have used some of the ultra light weight spackle to fill in where it was wavy. The rear sheeting went on without a problem.

Tomorrow should be cold and rainy all day. Hopefully I can get some more time to build.

Steve

The nose sheeting is the hardest part of the build, or it was for me, too.

You'll absolutely love the flight characteristics of this model, and it uses very little power.

Spad, I hope you are right about this being the hardest part of the build, then it means I'm home free! According to what Iíve read on this model, it seems there are three tricky points. 1st the nose sheeting, 2nd covering the tail fin, and 3rd getting the retracts to work. Some have also had problems with the pull, pull controls, but that does not seem as prevalent.

Some people have sheeted the fin so it's easier to cover. What did you do?

Default Tail Feathers

I did not make much head way today, but I did build the tail. The fin and rudder are another 3d puzzle, then glue with CA. The stabilizer and elevator are just a 2D puzzle built on the plan. 1st assemble all, then glue with thin CA. The Elevator halfs are joined with a dowel and some thick CA.

I'm not sure when I'll get a chance to start on the wing. It won't be tomorrow. It's mothers day and the kids and I have plans!

Yup, gotta take care of the boss......or you may find your build going much slower....... having to glue all the broken pieces back together and all.

Some have also had problems with the pull, pull controls, but that does not seem as prevalent.

Some people have sheeted the fin so it's easier to cover. What did you do?

Steve
Sheeted fin, no retracts.

Spad, If you have any pics or thoughts on how you sheeted, that may help me.

Default Wing 50% complete.

I got a chance to start on the wing tonight. You start by building the main spar and then some dry building again. (Other than some ply sheeting on two ribs.) You add a mix of 3/32 and 1/16 thick ribs and some 1/16 ply for where the landing gear attach. Some 1/16 balsa for the leading edge and for the top and bottom of the spars making two I-Beams. Then you finally get to glue everything together. This is where I stopped for the night. Step 17 of 33.

There are a lot of warnings about some delicate pieces where the landing gear attach to the wings. Of course I broke one when fitting the ply in and I broke the other when attaching the leading edge. In general you must be careful with a lot of interconnecting balsa pieces that are easy to break. I also cracked the leading edge piece when trying to get it into the last (smallest) wing rib. Other than that, no mishaps. The strength of the wing comes from two I-beam type spars. See the pictures. Now that I have glued the main parts of the wing together, it is already getting strong. Itís even beginning to look like a wing!

I looked at photos of real Mustangs, and used some very thin bals sheeting, wetting it well to shape it.
