An aircraft with a number of bumps and projections: Long pointy nose; retractable landing gear in pods (sponsons) that jut straight out; engine exhausts project out to the side; tail plane sticks out halfway down the tail cone; dorsal and ventral tail fin; odd-geometry side windows.

The first twin-engined civilian helicopter built in the United States. Numerous in New York, where they are in executive transport and police use. May be fitted with floats or tail-wheeled skids instead of retractable gear. The landing gear sponsons are shaped as airfoils, and provide some additional lift in flight.
