The pilot planned for a short local flight with a passenger between on-going aero-tow operations. In order to expedite the quick passenger flight, the pilot disconnected the tow line; however, he left the V-Bridal line attached to the rudder post of the airplane. The pilot had conducted previous flights in the same configuration without incident. During taxi, the pilot turned the airplane 180 degrees to position into the wind for takeoff. Shortly after rotation, the pilot experienced a uncommanded right turn. The pilot attempted to correct; however, he was unsuccessful. Subsequently, the airplane impacted terrain with the right wing and right main landing gear, and the airplane came to rest upright. Examination of the airplane by the pilot and Federal Aviation Administration inspector revealed the V-Bridal line became entangled in the rudder and tail-wheel during the takeoff. The forward fuselage structure was crushed, the left wing and left horizontal stabilizer were bent.
