04/30/2008. Designed by Dipl.-Ing. Peter "Pit" Krauss of Stuttgart, the single-seat TRS 1 was built in about two years by Pit and members of the Fliegergruppe at the airfield Kornwestheim. First flown in 1968, the gyrocopter enchanted by its clean design and by the performance and handling proven in test flights. The fuselage, butterfly tail and main landing gear were made of glass-reinforced plastic. The rotor carrier was of welded steel construction and functioned also as engine and fuel tank mount.
