The GyroBee was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 247 lb (112 kg). It features a single main rotor, a single-seat open cockpit without a windshield, tricycle landing gear and a twin-cylinder, air-cooled, two-stroke, dual-ignition 45 hp (34 kW) Zanzottera MZ 201 engine in pusher configuration.[1]
