Question

P38 Balsa Model?


The only place I have found one of these is on Guillows site and it's a giant one. Does anyone know where i can find one of these in the same or close size to Guillows 500 series planes?

Dumas P-38 is smaller:

Why do you want such a small P-38 model? The design's highly tapered wing favors a larger size unless you build it with very thin airfoils and light.

Well, one reason is the large ones are extremely expensive.

I can offer you some digitized plans in .PDF format of the 34 in. wingspan Comet version of the Lockheed P-38. Just e-mail me at rcarswellsr@att.net and be sure to mention you want the Comet Lockheed P-38 and I will send them back by return e-mail. No charge.

I was reading through an old MB, and stopped to drool over a P38 built by (IIRC) Hal Cover. The opinion was that the P38 was one of the easiest models to trim for freeflight, and I am sure it is true:

I built one using a HA Thomas plan from 1953 or so, profile at ~15" span, and it was a flying fool. Saw another one in the UK (Guillows, I think) putting in consistent flights on CO2.

Can't go wrong apparently, regardless of size or power.

Do you have any pictures?
My favorite plane is the Forked Tail Devil. You can't go wrong with it.

Balsa Flies Better!
I've seen that Comet one go- one of the guys who I fly with (who just caught his last thermal) had one that flew beautifully. There's also a Herr kit- don't know which one is better, Herr or Dumas. Do use counterrotating props though.

My RC P-38 at 60" is very scale, weighs in at 4 lbs- and is NOT relaxing to fly- it's got the most vicious stall of any airplane I've ever flown. It falls off on a wing with no warning. Landings are very high pucker factor.

God, I hate the pucker factor when it comes into play..........

I built the Comet 34" P-38 back in 1990. It was a challenge to make it fly with antique electric hardware back in the day! It was about 12oz with a 6-cell 600ma Sanyo nicad pack and a pair of geared Kyosho dmc-20bb motors. I was using an old cano throttle with a BEC hacked into it.

I foolishly discarded the plans for it. Fortunately I found a PDF of the plans and balsa sheets Anyway I think I'll roll this model again but using contest balsa, MicroLite covering, and some micro brushless outrunners. I'll shoot for about 6oz flying weight.

I'll post details and pics when I get started.

Anyone know where to get a large PDF printed? It's 57.21" x 22.72".

You do know that Mountain Models has a nice version of this airplane in this size range (38")? The wings probably need a little futzing with to look a bit more scale- I think there's more area in the tips, but the rest looks pretty good and is designed for RC. www.mountainmodels.com

Thanks for the comment.

Sorry for hijacking this thread for micro RC. But what I'm doing could also result in a fine FF electric.

The wood that was in the Comet P-38 kit was more akin to hardwood than balsa So pretty much any parts I use will need to be made out of hand selected contest balsa. I want a plane in the < 6oz range. I've built and flown the 34" Comet kit and it flies really nice and scale like.

The MM P-38 is a little bigger than what I want, and I'm sure the kit contents are also not suitable for a really lite build.

I built the Comet kit years ago, and it was a nice flyer and easy build. Couple years back I built the Dumas kit, but gave it away so I never flew it. The Dumas kit was straight forward.

Nice, I better think about the Dumas P-38! The plastic parts can either be used or serve as ready made molds. Looks like the wing shape is very similar (scale) to the Comet 34". A 30" is about 78% the wing area. Hmm
