Design and development

Based upon the Avid Flyer, which it greatly resembles, the Mohawk features a strut-braced high wing, a two-seats-in-side-by-side configuration enclosed cockpit accessed via doors, fixed conventional landing gear and a single engine in tractor configuration.[1]

The aircraft is made from metal tubing, with its flying surfaces and fuselage covered doped aircraft fabric. Its 30.00 ft (9.1 m) span wing features Junkers flaperons, has a wing area of 124.5 sq ft (11.57 m2) and is supported by "V" struts with jury struts. The plans specify standard hydraulic brakes, a steerable tailwheel and wings that fold for ground transport or storage. The standard engine used is the 50 hp (37 kW) Rotax 503 two-stroke powerplant, which gives a standard day, sea level takeoff distance of 100 ft (30 m) and a landing roll of 150 ft (46 m).[1]

The Mohawk has a typical empty weight of 450 lb (200 kg) and a gross weight of 1,000 lb (450 kg), giving a useful load of 550 lb (250 kg). With full fuel of 12 U.S. gallons (45 L; 10.0 imp gal) the payload for pilot, passenger and baggage is 478 lb (217 kg).[1]

The manufacturer estimates the construction time from the supplied plans as 900 hours. In 1998 the designer indicated that the aircraft could be completed for US$6,500 excluding labor.[1]

gollark: I don't have those. I just do computers. Besides, bioweapons could affect other people.
gollark: I would recommend against entering the field of bioweapon design.
gollark: I'm pretty sure lots of viruses cover themselves (partly) in marker proteins from human cells, so it's harder to deal with them.
gollark: If you could do that conveniently, we would probably already have evolved this capability.
gollark: They said an RNA vaccine. Anyone can make RNA. Maybe not the magic lipid things.
