Skymaster Rafael flutter issues ?
Has anyone had any flutter issues with the Skymaster Rafael. On the 2nd flight on the plane was doing opening up the throttle a little and the wings began to flutter very violenlty[X(]. Needless to say the left wing departed and the rest of the plane did a nice flat spin into the ground. The left ailevon was gone and the servo locked up and the right wing servo was stripped. Dont know which came first, wing flutter that killed the servos or servo failure that caused flutter ( 8411 sa's ).
