Design and development

The aircraft features a strut-braced high-wing, a single-seat open cockpit with a windshield, fixed conventional landing gear and a single engine in tractor configuration.[1]

The aircraft is made from welded steel tubing and wood, with its flying surfaces covered in doped aircraft fabric. Its 30.00 ft (9.1 m) span wing employs a NACA 2412 airfoil and has a wing area of 84.00 sq ft (7.804 m2). The cockpit width is 21 in (53 cm). The standard engine used is the 100 hp (75 kW) CAM 100 four stroke powerplant.[1][2]

The aircraft has a typical empty weight of 800 lb (360 kg) and a gross weight of 1,100 lb (500 kg), giving a useful load of 300 lb (140 kg). With full fuel of 11 U.S. gallons (42 L; 9.2 imp gal) the payload for the pilot and baggage is 234 lb (106 kg).[1]

The kit included prefabricated assemblies, the engine and scale fixed pitch propeller, basic VFR instruments, fabric and even paint. Also included were replica 7.9 mm machine guns and a ring gun site. The manufacturer indicated that the design was intended for novice builders and estimated the construction time from the supplied kit as 1400 hours.[1]
