Foamies!!!

Here's one I just built! It's a 27" Pitts Model 12 scratch built with carbon reinforced wings made primarily of Dollar tree foam covered in Ultracote.

And here's a foamy I'm almost done with. Not quite sure how well it'll fly... This has a 40" wing span, huge control surfaces, and is made from pink foam insulation covered in Ultracote.

Thanks! It's all in the Ultracote. That makes the dollar tree foam pretty stiff too and is a little lighter than the paper that comes on it.

I pulled the paper off first. Then slit the foam, ca'ed some carbon strips in it to span the wings/elevator, then covered with the ultracote before assembly. The finished wings were the same weight as the wings with just paper. The finished parts with no carbon(fuselage, wing struts, vertical stab) ended up slightly lighter than the foam with paper and seem just as rigid.
