hi derek, check at a building supply center for rigid roof insulation, it usually comes in 4'x8' sheets and the thickness veries. i have used this rigid foam insulation up to 8" thick. it will have a slight taper from one side to the other for roof slope on a builtup roof system. the material is very dense, durible and water proof, easy to cut and work with, pepa.

It's funny I found this post when I did. I have freind taking classes for his air frame lic. for the FAA. The "foam" used is not the type sold at a hardware store, it's special foam with a differant structure used for airframes. He has made actual scaled down wings using composite materials, the idea is the same though. Monday he's going to ask his instructor to see about getting large sheets and the materials to build some for me. He says the stuff is awsome! You just cut it with a hotwire and lay the resin on and then lay a section of "fabric" on top and roll the bubbles out. If you use regular foam it melts. That's my .02 worth.
