Witnesses reported the engine sounded normal during the takeoff roll and that the airplane rotated normally. Witnesses reported the airplane climbed to about 100 to 200 feet when the engine revved up 'really high' to what sounded like 1,000 RPM's higher than normal takeoff power. A witness reported the airplane went into a 60 degree left bank, and then the airplane turned right into an 80 degrees nose dive. The airplane went straight down and did not spin. The stall speed of the airplane was 50 mph. The airspeed indicator was found with the needle stuck at approximately 41 mph. The engine and flight controls exhibited continuity and no pre-impact anomalies were revealed. The engine was modified for airplane use by utilizing a propeller belt reduction drive to reduce the engine RPM's to approximately 2,500 propeller RPM's. The two 30 mm wide reduction drive belts were not found at the impact site. Searches for the drive belts were made of the surrounding area on two separate occasions but without success.
Probable Cause: the pilot inadvertently stalled the airplane. A factor was the failed reduction drive belts.
