The pilot reported that after landing, he planned to make an immediate departure. During the takeoff roll, about halfway down the turf runway, the airplane traveled over “rough runway conditions” and bounced several times. The pilot assessed the situation and decided to abort the takeoff. Due to the rough surface and the constant bouncing of the airplane, the pilot was unable to stop the airplane before it departed the runway. The airplane nosed over and came to rest inverted, and the pilot was able to egress from the airplane without further incident. The airplane sustained substantial damage to the right wing, the left wing strut, and the vertical stabilizer. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe and the engine that would have precluded normal operation.
