Default Mountain Models / Laser Arts 37" p-51

The mailman brought me a nice toy today. It's the Mountain Models / Laser Arts p51.

SPECS:
  • 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 ordering and shipping process was flawless. I ordered last Thursday ... the kit shipped the next day and arrived today. The kit was well packaged and in perfect condition.

In addition to the kit, I also ordered a GWS 10x8x4 prop and spinner, and a set of GWS "blue" retracts from their website.

I had also mentioned to Brian (the kit designer and company owner) that I was probably going to go with an outrunner rather than the recommended inrunner/gearbox, so he included (free of charge) a brushless mount that he'd been working on for this kit.

The kit contains a full set of vacuum formed plastics. Included are the canopy, a detailed cockpit interior, cowl, belly scoop, and engine exhaust ports. There's also a vacuum formed spinner and backplate, which is a nice surprise. Other threads I had read used the GWS 4-blade spinner which pretty much locks you into the 10x8x4 (which really isn't optimal for this plane) ... this gives me the possibility of expanding my prop options ... including a vario! The vac-formed spinner must be a recent addition to the kit.

Finally, a small parts bag includes some of the more delicate or off-sized laser cut parts, a small dowel, the main gear wheels and a tailwheel, a soda straw (whose purpose I'm sure will be clear later), nylon screws, various bits of velcro, some EZ connectors, and the string and various bits necessary for hooking up the pull-pull system for the rudder and elevator surfaces.

With the holidays coming up, I'm not sure how quickly this build will progress, but I wanted to get this 'teaser' up. It'll help motivate me to sit down and glue sticks together!

I have one of these kits... I've had it for over a year, someday I'll get around to building it. Looking forward to seeing your results.

I've got several ideas, but I'm far from narrowing it down yet.

I'm definitely planning on a military theme (as opposed to a post-war sport look), and to go for a 'look' that was used during the period. However, I'm not planning on copying any specific ship.

The factors driving the final decision will be
  1. High visibility - so invasions stripes will definitely be incorporated
  2. Easy to implement - I'm not really very artistic and I'm relatively inexperienced with covering
  3. Period correct - While not copying any specific ship, I want a look that could have been flying in the war.
Design elements I've seen and liked on p-51's (may or may-not make final cut):
Checkerboards on the nose
Shark mouth and eyes
Panel lines
Invasion stripes
Black glare reduction
Red or yellow tail section
"Bare metal" fuse (I won't go for one of the fully painted schemes)
Nose art and or names (I've got a name in mind ... nose art is a possibility if I find something that jazzes me and I can make a decal from it)

Thanks GH. I hadn't seen that page before. That ought to get the creative juices flowing.

I've decided to ease into this build and get the cockpit painted up.

The paint was applied with a brush using Testors model paints.

The green is #1164 Flat Green
The Seat color is #1184 Zinc Chromate
The black #1149 Flat black
The yellow is #1169 Flat Yellow
and The Silver is #1146

I'll probably also end up using the silver for painting the canopy frame and also to match the covering. I have heard the Testors silver is a good match for most silver covering films. I'll hold off on painting the canopy probably until last. I'm frankly a little nervous about that ... I don't want to mess up such a visible item.

For your viewing pleasure...

Hey Gnascher! I'm guessing that you'll be ready to maiden by sunday evening, right? LOL.
You're off to a good start! I'll definately be following along.

Yes ... I'll do her maiden by the light of the waning moon.

Seriously though ... not sure when that'll happen. I reviewed the instruction manual today. Doesn't look too bad of a build. However, I still need to settle upon a power system. I've ordered a RX (found a nice deal on an AR6000 for $35 on eBay), and I still need to pick up 5 servos. Also, since I haven't settled on a trim scheme, I haven't ordered any covering material yet either.

I'm figuring this will more than likely be a post-christmas maiden. Santa will probably help with the last bits and pieces I need and I've taken the week after x-mass off, so I should be able to button it up then.

Nice job on the cockpit Gnascher. If the rest of it looks that good, you won't want to fly it.

Definitely before she maidens! I would most certainly appreciate having you give it a once-over before I tempt gravity with it.

I got the fuse built today. That's probably all I'm going to accomplish until next week .... family's descending upon us starting Wednesday and through the weekend.

It took probably 3 1/2 hours to assemble the fuse. The manual is clearly written and the laser cutting is immaculate. Everything's fitting together like a jigsaw puzzle.

I did make one minor error though. I put the pieces that carry the wing-mount nuts on backwards. I had to cut them out and re-glue them 'round the right way. Oops. It's totally my fault. The manual's clear on how they're supposed to go, I just got dyslexic on that part.

If the rest of this build goes this smoothly, I should have the bones assembled before Christmas.

Thanks Frank! I'm looking forward to flying this plane. The fuse came out very light and strong ... I'm impressed with the rigidity of the structure.

When I was popping the stringers out of the sheets, they seemed so weak I was a little concerned. But now that it's all together with each piece receiving the proper support it's deceptively strong.

I think the only place I'm going to deviate from the stock build for the fuse is to sheet the underside of the nose since this plane will be an occasional bellyflopper and a little more robustness in that area could be important.

I had a little time today, so I sheeted the fore and aft decks today.

The kit provides two sheets for the nose and two sheets for the tail section that are meant to be joined in the middle with CA and then moistened and curved over the surfaces.

This works well enough for the tail (be sparing with the CA when you join the halves or you'll get a stiff section down the middle) since it's a reasonably simple cone-shaped section.

However, the nose is a compound curve and I could not get the sheet to lay nicely ... the middle former of the nose was actually deforming as I tried to match the contour. So, I decided that I'd probably get a better result if I planked it instead of using the single sheet. It took a little longer, but the result was worth the effort I think. In the last two shots, you can see I still had an issue with the last plank buckling ... a quick relief cut and filling the gaps with CA got it to lay flat.

Prior to sheeting, the fuse was at 1.3oz ... the sheeting brings it 1.6. I still have the small forward section of the belly to sheet, but I can't imagine that could add even as much as another 1/10th oz ... so I'm figuring this part of the build to end up between 1.3 and 1.4 oz.

Looks great so far! I want to go ahead and order one, but am still trying to figure out what power system to use. What outrunner are you going with?

It's cheap enough that if I cook it I won't cry over it.

You don't have that plane flying yet? Geez!

Just kidding. I like taking my time and enjoying the building process. It's looking good!

I hear ya. We're hosting Thanksgiving this year (30 people) ... and for some reason my wife thinks I need to be helping out around the house instead of gluing my fingers to little pieces of balsa.

I'll probably pick up speed over the next week or so. I haven't ordered covering ... or even settled on my trim scheme.

Where did you find this website / supplier? Interesting, although the motor information is pretty sketchy.

You can better specs on the "motor with prop" combo, but admittedly it's still not a lot to go on.

Default Tailfeathers assembled

Well, Thanksgiving's come and gone. Thirty friends and family were fed on a 28lb turkey AND a 20lb Turducken (lots of leftovers) and all the usual side dishes and my house is finally back in order.

I was finally able to sit down and do a little more building. The tail feather assemblies are now complete. Not much to say about this process it was very straight forward. I figure I took about 2 hrs to complete these steps.

The wings are next ... I'm really looking forward to that part of the build!
