Probable cause
The pilot's failure to attain and maintain an adequate flying airspeed during the aircraft's maiden flight, which resulted in a stall/mush condition. Also causal was the pilot/builder's decision to modify the engine and the fuel system control microchip, which resulted in detonation and a severe reduction in power output, and led directly to the pilot's inability to attain and maintain airspeed.
