Design and development

The ML 500 complies with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced parasol wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in pusher configuration.[1][2]

The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in Dacron sailcloth and the cockpit enclosure is built from fibreglass. Its 10.3 m (33.8 ft) span wing has an area of 14.7 m2 (158 sq ft) and is supported by V-struts and jury struts. The tail is mounted to a small diameter aluminium tube. The standard engine available was the 64 hp (48 kW) Rotax 582 two-stroke powerplant, mounted on the wing trailing edge. The landing gear can be equipped with optional wheel pants.[1][2]
