The AutoGyro MT-03 is a German autogyro, designed and produced by AutoGyro GmbH of Hildesheim. The aircraft is supplied as a complete ready-to-fly-aircraft.^[1]

The MT-03 was approved in the United Kingdom in 2007 in a modified form as the RotorSport UK MT-03.^[2]

Design and development

The MT-03 features a single main rotor, a two-seats in tandem open cockpit with an optional partial cockpit fairing, tricycle landing gear with wheel pants and a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 100 hp (75 kW) Rotax 912 engine or turbocharged 115 hp (86 kW) Rotax 914 engine in pusher configuration.^[1]

The aircraft fairing is made from composites. Its 8.4 m (27.6 ft) diameter rotor has a chord of 20 cm (7.9 in). The aircraft has an empty weight of 245 kg (540 lb) and a gross weight of 450 kg (990 lb), giving a useful load of 205 kg (452 lb).^[1]

The MT-03 was developed into the MTOsport and the fully enclosed AutoGyro Calidus.^[1]

Operational history

The MT-03 was flown on a world record-setting distance flight in Australia of 1,263 km (785 mi).^[1]

An AutoGyro MT-03 was used by Norman Surplus in his nine-year global circumnavigation that ended in 2019; the first to be done in an autogyro.^[3]

Variants

AutoGyro MT-03: Base model for the European and North American market. No longer in production.^[1]
RotorSport UK MT-03: Modified model for the United Kingdom market, imported assembled and modified by RotorSport UK.^[2]
AutoGyro MTOsport: Improved model for the European and North American market. This model offers a choice of three different rotor systems, two different propellers, two engine choices (Rotax 912S or 914) and floats.^[1]
AutoGyro MT0-Free: Version of the MTOsport, with no cockpit fairing fitted. This leaves the pilot out in the open air and has the benefit of eliminating the need for rudder input when turning, as the fairing acts as a destabilizer.^[4]
