Sorry for delay. This is direct result of 3 or 4 seconds long lasting flutter. The wings was not damaged prior to the flutter. It was brand new plane flown with ease.
Aileron servos: Hitec HS-8335SH with 2S LiFe battery (18.5 Kg/cm at 6V; 0,16s/60degree at 6V).
Ailerons went crazy during flutter but I dont remember what happened in the first place, flutter on ailerons caused flutter of wings or other way around.
I will post pictures once I got home
