The pilot reported that, he had performed a practice candy drop pass over a field about 300 ft above the ground. During the climbing 30º banked right turn to circle back to the field, he "neglected [the] airspeed" and the airplane aerodynamically stalled, descended striking trees, and impacted the ground inverted.
The airplane sustained substantial damage to the left wing and empennage.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
