RE: Great Planes Reactor in Flight Elevator Failure on First Flight
it kinda looks like it broke where the hinge is installed which makes sense since that is where a stress riser would be. So a hole in an unfortuanely picked piece of balsa and snap, broke at the weak spot. Probably just bad luck.
Honestly, I would just re-do that side of thr elevator and not bother calling GP, after all whats the best outcome for that? They give you a new piece and its actually more work installing the new piece than it is fixing it withou the free piece right?
Good luck (nice job landing it by the way)
