 The machine was a simple, cross-shaped frame, with the pilot standing on a platform, secured by a safety harness. The harness also secured the aircraft's engine, which was an outboard motor manufactured by Mercury Marine. The engine was controlled by a twist-grip motorcycle-style throttle and transferred power to the 15-foot (4.6 m) diameter, contra-rotating rotors via belt drive with a chain reduction unit. The aircraft's landing gear consisted of airbags at the end of each arm of the frame along with a large rubber float in the middle, allowing for amphibious capability, although this arrangement was later replaced by a pair of conventional helicopter-type skids.
