About 5ft Above Ground Level, The Airplane Stalled, And The Left Wing Dropped Analysis: The pilot reported that this flight was conducted as part of phase 1 flight testing of the newly constructed experimental amateur-built airplane. The pilot stated that he had watched a video from the airplane kit manufacturer on “factory takeoff,” which suggested keeping the control stick slightly aft of neutral and applying partial power. During the accident takeoff, he tried the method described by the video and when the airplane lifted off, it was too slow. About 5ft above ground level, the airplane stalled, and the left wing dropped.
