Design and development

The Deltacraft MD-40 was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 340 kg (750 lb). 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.[1]

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).[1]

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.[1]

gollark: Surround the country in a solid hemisphere of pure iron.
gollark: What of an *actual* iron dome?
gollark: What? That's $106500 a child. They could probably rent each an individual apartment somewhere for that much.
gollark: When I attempted to be involved in the democratic process™ by complaining to my local politician about a thing their government had done, I got no useful response out of it. I don't think it's worth the time.
gollark: You seem to be able to actually remain motivated to study interesting maths and such. I get distracted from anything like that *very* easily and can only really do it in very small chunks.
