It features a cable-braced hang glider-style high-wing, weight-shift controls, a single seat open cockpit with a streamlined cockpit fairing, retractable tricycle landing gear and a single engine in pusher configuration.
The aircraft fuselage is made from composites, with its aluminum-framed double surface wing covered in Dacron sailcloth. The wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, air-cooled, two-stroke, dual-ignition 50 hp (37 kW) Rotax 503 engine. The MD-40 has an empty weight of 160 kg (353 lb) and a gross weight of 340 kg (750 lb), giving a useful load of 180 kg (397 lb). With full fuel of 28 litres (6.2 imp gal; 7.4 US gal) the payload is 160 kg (353 lb).
A number of different wings can be fitted to the basic carriage, including a wing with an area of 16.7 m2 (180 sq ft) produced by the company.
