The pilot reported that during takeoff the wind shifted from a crosswind to a quartering tailwind. He further reported that immediately after rotation at 45 knots, the airplane began to drift to the left and would not climb. Subsequently, the pilot aborted the takeoff and touched down to the left of the runway about 20 feet before a wire fence. The nose wheel caught on the wire fence and the airplane nosed over.
The vertical stabilizer and fuselage sustained substantial damage.
The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation.
