Design and development edit
The aircraft features a biplane layout, a single-seat, open cockpit, fixed conventional landing gear and a single engine in tractor configuration. The Sportster was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 252 lb (114 kg). It was intended to resemble biplane of the 1930s and mounts its upper wing not on cabane struts, but on a central pylon that has a tunnel to allow the pilot forward vision.[1]
The aircraft is made with mixed construction, from aluminum, steel, wood and foam. Its 17.5 ft (5.3 m) span wings have a total wing area of 82 sq ft (7.6 m2). The cockpit width is 20 in (51 cm).[1]
The aircraft has a typical empty weight of 252 lb (114 kg) and a gross weight of 460 lb (210 kg), giving a useful load of 208 lb (94 kg). With full fuel of 5 U.S. gallons (19 L; 4.2 imp gal) the payload for the pilot and baggage is 178 lb (81 kg).[1]
The manufacturer estimated the construction time from the supplied kit as 400 hours.[1]
The company later turned its attention to produce unmanned aerial vehicles for the US Navy and no longer produces manned aircraft.[2]
Operational history edit
By 1998 the company reported that two Sportsters had been completed and were flying. Customer kits were forecast to start shipping in March 1998.[1]
