Takeoff Procedure
The pilot initiated a soft field type takeoff with 10 degrees of flaps. He reported starting the takeoff with the control wheel held full aft until the aircraft became airborne, then lowering the nose to remain in ground effect.
Loss of Control
However, the pilot failed to maintain adequate airspeed and the aircraft drifted to the left of the runway, toward trees. He stated that power was set to full, but the airspeed was not sufficient to maintain controlled flight.
Impact
Subsequently, the aircraft crashed in a controlled manner into the trees. No preimpact part failure or malfunction was reported.
