Guillows P-38.

Not sure where to put this one. It is a Guillows, yet it's a scratch foamy also. I 'm using the plans and the plastics from the kit, but the airframe is all foam. 8 oz as she sits but I'm sure a couple more by the time the rest of the details get added.

The wing is built with spars and sheeted like sparks cartoon fatties, but the fuse and booms are more jetset44 style. Of course it has stayed the same size as the Guillows.

62Pilot - plane has foam, you're in the right place. Cool looking P-38. Any idea as to motor size?

I have a couple of 1100 kv swinging 8 in props from HK that should do fine. 2250 3 cell in the pod should give about 10 min flights.

62,
Looks awesome! How did you cut the foam? CNC?

It is 3,6 and 9 mm cellfoam. I just used an xacto. And then sanded the crap out of it. The booms are built as a box and rounded over to shape. The center pod is layered top to bottom and then sanded.

Very cool!
I've have the Guillows plastic parts for some time now. Used only the engine turbo/intake bits to dress up a slightly smaller MM-P38. Since I the little MMP38 was destroyed (didn't pull out of a split-s) I've bee dreaming of doing exactly this. Several other projects on the table right now but will sure watch your build.

Retracts?

I built a foam Birddog from an 18 in kit and used all the non wood parts , powered with UM guts and it looked fantastic. I have a P-38 NIB but was given a full set of plastics ( been sitting on them about two years now) so I thought what the heck. No plans for Gear at all, just belly landings. Stll have a lot of sanding and filling before paint. Maby I can get back on it tommorow. Been building a custom display cessna 182 for a freind.

Give some thought to protecting the lower tail fins in belly landing a P-38. I've chewed up or torn pieces off a couple of times now.

I was thinking maybe a bent wire skid glued into the leading edges of the fins. Or maybe a plywood insert for a LE. Or a separate wire skid in front of them.

Maybe you can come up with something better!

Can't wait to see it fly.

I was thinking of doing the ply insert in the foam, or just some CF vail covering the entire stabilizer. May just go with full balsa as that area of the booms is pretty thin and springy, it would give a boat load of support for the weight.

Ply LE insert is going to be the lightest and toughest of those, I think, as well as the easiest to do. I'm going to take my own medicine on that!

Second the ply LE insert idea for the fins. I definitly had a problem with the lower portion of the fins catching and breaking on my little MM-P38. What happens is the nose or a nacelle catches something and tail skids around sideways and a fin hits something. Retracts could be an even bigger headache, depending on your runway. If you're not planning rudders then simply planning to replace broken fins every few flights may be less problematic, and lighter, than designing them not to break on landing. Or maybe cut the lower portions off and re-attach with a 2 or 3 small RE magnets. Enough to hold in flight but break away easily if they snag something solid.
