LOL I feel more sorry for your neighbors, I could only imagine what they where thinking when the plane hit the roof
I'm not going to give you the 10th degree on flying ethics, I'll let someone else do that, but please try to be more careful in the future for the sake of all RC pilots.
As far as the wing folding been there done that with a Freedom flier. I figured after I hopped up the motor to a 400 from a 200 This was the cause for the wing folding in an aggressive up elevator maneuver.
Sorry and stick with it [sm=punching.gif] .
Good Luck.
