The Roll Flight MR V is a German powered parachute that was designed by Martin Rütter and produced by Roll Flight of Schwelm. A two-seat version is known as the Duo. The aircraft is supplied as a complete ready-to-fly-aircraft.^[1]

The MR V was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). It typically uses a 40 m² (430 sq ft) parachute-style wing, but a variety of wings can be used and the choice determines the aircraft's gross weight. It features two-seats-in-tandem or single-place accommodation, tricycle landing gear and is set up to accept a single 28 hp (21 kW) Hirth F-33 engine in pusher configuration.^[1]

The aircraft carriage is built from metal tubing. In flight steering is accomplished via handles that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has pedal-controlled nosewheel steering. The main landing gear incorporates spring rod suspension.^[1]
