According to the pilot in the experimental amateur-built airplane, he was conducting a flight test. During the takeoff roll, he applied "too much aft stick," and the airplane entered an unintentional steep climb at a low airspeed. The airplane rolled left about 30°, he corrected to the right and the airplane's nose dropped. The pilot further reported that he may have reduced the throttle and overcorrected to the right. The airplane stalled and impacted the ground.

The airplane sustained substantial damage to the right wing.

The pilot reported that this was his second flight in the accident airplane.

The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
