No I have not contacted GP, I thought I should have some idea of the problem or I'm gonna sound like an idiot. We did find a few parts, I originally thought the entire stabilizer seporated from the left side, but we found the elevator. the hinges are still in the elevator and the half that was glued to the stab still has balsa attached. It looks like either the trailing edge of the stab was very soft wood and pulled, or we had flutter. After soaking in a swamp for 4 days its kind of hard to tell. We still have not found the fuse, engine, or radio I think it sank.
