The pilot told an FAA inspector that he and his passenger departed on runway 35 and planned to practice touch and go landings. He initiated the take off roll from mid-field with a tailwind, and said that the engine was not producing enough power needed to safely depart. The pilot continued the take off and once airborne, the airplane stalled and collided with trees at the end of the runway. The pilot said the engine was running at the time of impact and there were no mechanical problems with the airplane. The airplane sustained substantial damage to each wing, the fuselage, and the right elevator. Winds at a nearby airport were reported as wind 160 degrees at 8 knots gusting to 17 knots.
