Design and development

The Monarch was designed to comply with the US Experimental - Amateur-built rules. It features a single main rotor, a single-seat open cockpit without a windshield, tricycle landing gear with wheel pants and a twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine in pusher configuration. [1]

The Monarch's fuselage is made from metal tubing and mounts a two-bladed main rotor with a diameter of 8 m (26.2 ft), with an electric pre-rotator to shorten take-off distances. The aircraft has an empty weight of 360 lb (160 kg) and a gross weight of 630 lb (290 kg), giving a useful load of 270 lb (120 kg). The tail surfaces are made from Kevlar. The landing gear is of 4130 steel construction, incorporates springs and has a long stroke of 18 in (46 cm) to allow almost vertical landings, including descent rates of 500 ft/min (2.5 m/s) at touchdown. The tricycle landing gear is supplemented by a triple tail caster. [1] [2]

Optional equipment available includes a cockpit fairing with a windshield, rotor brake, auxiliary 6 U.S. gallons (23 L; 5.0 imp gal) fuel tank and an airshow smoke system. [2]
