The NTSB's narrative final · quoted from the NTSB record

The pilot purchased the amateur built airplane already constructed. On his first flight he reported a lack of aileron control at slow speed. He attempted to obtain the services of another pilot to fly the airplane and evaluate it. The other pilot made a high speed taxi test and then refused to fly the airplane. The owner/pilot then attempted a flight, lost control on liftoff and impacted the terrain. An inspection of the airplane after the accident revealed asymmetric deflection of the ailerons. The right aileron deflected 6' in either direction, while the left aileron deflected 3' in each direction.
