Design and development

The MH-1 is provided as a series of kits to upgrade old Mini-500 airframes, allowing the owner to modify them to MH-1 standards. The kits include a new Yamaha engine of 130 hp (97 kW), that replaces the Mini-500's 64 hp (48 kW) Rotax 582, plus a new mount for the Yamaha engine. The remaining kits cover modifications to the main transmission, the tail, main drive and clutch basket, radiator fans and relay and the rotor head. The resulting MH-1 complies with the US experimental - amateur-built rules.[1][2]

The MH-1 features a single main rotor with a two-bladed tail rotor, a single-seat enclosed cockpit with a windshield and skid-type landing gear. Its 19 ft (5.8 m) diameter two-bladed rotor has a chord of 8 in (20.3 cm). The aircraft has an empty weight of 600 lb (272 kg) and a gross weight of 1,100 lb (499 kg), giving a useful load of 500 lb (227 kg).[1]

The Federal Aviation Administration approved the MH-1 conversion as a distinct aircraft type.[1]
