Nagler's Model NH-160 single-seat helicopter first flew in 1955. The VG-1 Vertigyro developed later comprised a Piper Colt aircraft fuselage with conventional engine. Its rotor system was driven by a turbine engine, enabling the craft to be flown as a gyroplane, a helicopter, or a combination of both.
