Zor, it's referred to in almost every kit as light ply and sold through every wood supply as light ply. It's just three layer Birch ply. The kit that comes to mind is the CG Extra, the fuse is built from light ply with lightening holes cut in it, sides and formers. It tends to warp easily so some kits made from the stuff used notches and tabs to keep things straight. Some of the new ARFs are using a very thin kind of hardwood outer layers with a balsa center. So far I haven't seen it sold through any of the wood suppliers I use. I use Mid West and Testors light ply. The stuff doesn't work well with CA glue so with any of the plys and hardwood I use epoxy so a build takes me longer when using it.
Behold, I think I see a plane emerging from all the sticks!!! Today I built the two stabs and elevators. More sticks but they are at least balsa and the building went much faster. I built each wing half when I got home from flying in two days. Took one day more to epoxy on the center section 1/32 ply using epoxy as the glue. The design of the center section just keeps the balsa from being crushed by the rubber bands. The bottom sheeting helps to align the wing in the wing saddle. Old design but still had some good ideas.
