DURING THE TAKEOFF ROLL THE PILOT WENT FROM NEGATIVE TO POSITIVE FLAPS AFTER THE CONTROLS BECAME EFFECTIVE. THE FLAP TRANSITION WAS RAPID AND THE GLIDER BEGAN TO OSCILLATE IN PITCH. THE OSCILLATIONS BECAME DIVERGENT AND THE GLIDER ROLLED OFF ON A WING AND COLLIDED WITH THE GROUND SHORTLY AFTER THE SAFETY ROPE PARTED. THE PILOT STATED THAT HE WENT FROM NEGATIVE TO POSITIVE FLAPS TOO QUICKLY RESULTING IN LOSS OF CONTROL.
