The light sport aircraft student pilot was practicing short field takeoff and landings in the experimental light sport airplane. He reported that during the initial climb out phase of the two prior takeoffs, the airplane yawed to the left, and that he countered this motion by lowering the airplane's nose. On the third takeoff attempt, he applied full engine power during the ground roll; the airplane rotated, and immediately yawed to the left towards the adjacent hangars. The pilot attempted to turn the airplane away from the hangars but the left wing dropped and the airplane collided with the ground. The airplane sustained substantial damage to the forward fuselage, and both wings. The pilot reported that the winds were calm, and there were no mechanical anomalies with the airplane’s engine or flight control systems.
