The Historical P-40C Tomahawk is an American homebuilt aircraft that was designed and produced by the Historical Aircraft Corporation of Nucla, Colorado. The aircraft is a 62.5% scale replica of the original Curtiss P-40C Tomahawk and when it was available was supplied as a kit for amateur construction.[1]
Design and development
The aircraft features a cantilever low-wing, a single-seat enclosed cockpit under a framed aircraft canopy, retractable conventional landing gear and a single engine in tractor configuration.[1]
The aircraft is made from welded steel tubing covered in a shell of polyurethane foam and fiberglass. Its 24.50 ft (7.5 m) span wing, mounts flaps and has a wing area of 100.00 sq ft (9.290 m2). The cockpit width is 21 in (53 cm). The standard engine used is the 230 hp (172 kW) Ford Motor Company V-6 automotive conversion powerplant.[1]
The aircraft has a typical empty weight of 1,347 lb (611 kg) and a gross weight of 1,938 lb (879 kg), giving a useful load of 591 lb (268 kg). With full fuel of 42 U.S. gallons (160 L; 35 imp gal) the payload for pilot and baggage is 339 lb (154 kg).[1]
The aircraft has fairly lengthy runway requirements with a standard day sea level take-off distance of 1,200 ft (366 m) and a landing distance of 1,500 ft (457 m).[1]
The kit included prefabricated assemblies, the engine and scale fixed pitch propeller, instruments, avionics and even paint. The manufacturer estimated the construction time from the supplied kit as 2000 hours.[1]
