Tandem rotor machine powered by a 100hp Franklin engine. It had a neat fuselage of steel tube covered with aluminium and fabric, with a tricycle undercarriage and a forward cockpit for two occupants seated in tandem. The rear pylon allowed the rear rotor to turn on a higher plane than the forward rotor so that the arcs could overlap safely.
