RE: what causes flutter?
ORIGINAL: Jburry
We got her back, and post mortem revealed a failed glue joint on the elevator joiner. With the non-driven elevator half free, it fluttered and tore the stab half-off.
Ran outa elevator on approach, and had to land hot, but landed anyway. Rebuilt the stab (harder balsa, thicker, carefully airfoiled), and now she happily stands hard pull-outs from terminal power dives.

The broken Stab half turned into a tiller, which affected flight.
Pulling up on the nose caused a corresponding lateral movement.
It was quite hairy getting the plane down, but it did bring a round of applause from onlookers.
