This helicopter is among the most innovative ships invented by pioneer helicopter designer Frank Piasecki. The pilot was placed on the starboard side of the vehicle so the collective pitch lever did not interfere with the pilot's downward visibility. Large enclosed rotors made the helicopter one of three winners of the US Army's competition for an "invisible" aerial vehicle capable of nap-of-the-earth flight. The helicopter was designed to hover, land and travel as a ground vehicle on its three wheels.
