Why can`t I simply use the foam to carve whichever plane I like, and use it as the form around which I build a fibreglass plane? I would then dissolve the foam once I`ve put down the required layers of fibreglass.
I designed and built a North american X15 using that method. it was powered by 2 Estes D12-0 booster rockets and was air launched (with some success) from the belly of a modified Kadet Sr.
The wings were built up balsa as was the tail, but the Fuselage was all glass(1.5oz I think)
I made the mold from foam, then I cut 2 or 3 groves along the length of the fuse and then sliced the fuse into 3 parts. then I built light ply bulkheads and epoxied the fuse parts together and epoxies 1/4X1/4 balsa stringers in the groves. then glassed and sanded and glassed and sanded...
The worst part was removing the foam after. I cut it by hand for the most part, but dissolved the rest with gas.

It was quite a project (Many years ago) and did fly (mostly), but I had fun with it and learned a few things.
