The Explorair Relax MV is a German powered parachute that was designed by Mathias Mauch and produced by Explorair of Ebringen, Breisgau-Hochschwarzwald in Baden-Württemberg. Now out of production, when it was available the aircraft was supplied as a complete ready-to-fly-aircraft.[1]
The aircraft was introduced in about 2002 and production ended when the company went out of business in 2004.[2]
Design and development
The Relax MV was designed to comply with the Fédération Aéronautique Internationale microlight category and the US FAR 103 Ultralight Vehicles rules.[1]
The Relax MV features a 42 m2 (450 sq ft) parachute-style wing, single-place accommodation, tricycle landing gear and a single 28 hp (21 kW) Explorair-converted Briggs & Stratton four stroke engine in pusher configuration. The aircraft carriage is built from a combination of composite material and bolted aluminium tubing.[1]
The carriage can be converted for use with a hang glider wing as an ultralight trike.[1]
The aircraft has an empty weight of 115 kg (254 lb) and a gross weight of 250 kg (551 lb), giving a useful load of 135 kg (298 lb). With full fuel of 22 litres (4.8 imp gal; 5.8 US gal) the payload for pilot and baggage is 119 kg (262 lb).[1]
