The Historical PZL P.11c is an American homebuilt aircraft that was designed and produced by Historical Aircraft Corporation of Nucla, Colorado. The aircraft is a 66% scale replica of the Polish PZL P.11c fighter and when it was available was supplied as a kit for amateur construction.^[1]

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]
