==Design and development== The MR V was designed to comply with the [[Fédération Aéronautique Internationale]] [[microlight]] category, including the category's maximum gross weight of {{convert|450|kg|lb|0|abbr=on}}. It typically uses a {{convert|40|m2|sqft|abbr=on}} [[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 {{convert|28|hp|kW|0|abbr=on}} [[Hirth F-33]] engine in [[pusher configuration]].<ref name="WDLA04"/>

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.<ref name="WDLA04"/>
