The pilot of the motor glider reported that he taxied to a transient parking area with the wings in a folded position. After parking and unfolding the wings, he began to taxi the glider to the active runway. He reported taxiing to the right of the center line in order to avoid making contact with the hangars to the left. The pilot then looked ahead and observed three airplanes in the run-up area, and shortly thereafter, the glider's left wing tip made contact with a hangar. The glider then spun to the left and collided with the hangar. The left wing sustained substantial damage during the accident sequence.
