Single place amphibious helicopter derives its name from its unusual layout and control; pilot stands on small platform beneath which contrarotating rotors whirl, flotation pontoons being disposed under roters; prototype aircraft is powered by Mercury outboard racing motor, liquid cooled twin-cylinder 2-stroke unit with rotary valve induction.
