Thanks i need the help cause dont want to happen again.  The servos where brand new just installed on plane. battery was fully charged. the radio sysem is brand new.  It was first flight on everything. I seen nothing out of ordinary on flight it was doing great.  I flown at full throttle no problem i was at half throttle just doing standard flight when this took place.   The plane done a spin out in air and could not recover it . throttled back thats when i seen aelirons fluttering. By the way they where flopping they stripped in air.  the wing was not damaged in crash.  hinges worked great.  i done alot checks on plane before flight. But ya never know might have over looked something.  I have crashed my share of planes but never had a mechanical failure like this. Only thing i can think of aelirons on this plane are much larger than what i have flown in the past. Just wondering if standard nylon servos are not the way to go on 3d planes
