Tried that. It ended up breaking . The foams kind of lime hk foam but slightly less brittle. The curve just goes back. It's quite thick paper.

I have bent and formed foam with a real hot rag placed on top. You have to keep this rag very hot at all times until the foam is to your liking. Hope this helps.

This is a new wing I am designing and have already produced a test panel. The actual wing which is about to be assembled will be a 2 piece 2.7m symmetrical for glider aerobatics.

In the pictures the wing looks almost symmetrical in shape. What airfoil do you aim to achieve?

No particular airfoil. First flights will tell us a lot how this thin foil will do. When I reveal the way we are flying you will see foil designation isnít really a concern as long as itís just Sym.

Why not consider going bigger like 2.5 meter? The wing assembly process has been recently proven, and the prototype glider for low flying aerobatics is nearing completion.

I'm not sure how long that high a kv motor on a 7x5 prop on 3s is going to last
A 6x5 on a 2200kv is about the max so I'd expect something to smoke
