Design and development

edit

The Culp Special is intended to resemble an aircraft of the 1930s. It features a wire and strut-braced biplane layout, a two-seats-in-tandem open cockpit with dual windshields, fixed conventional landing gear with wheel pants, and a single engine in tractor configuration.[1]

The aircraft is made from welded steel tubing and wood, all covered in doped aircraft fabric. Its 24.00 ft (7.3 m) span wing has a wing area of 161 sq ft (15.0 m2). The standard engine used is the Russian 360 hp (268 kW) Vedeneyev M14P nine cylinder, air-cooled, four stroke radial engine.[1][2]

The Culp Special has a typical empty weight of 1,480 lb (670 kg) and a gross weight of 2,100 lb (950 kg), giving a useful load of 620 lb (280 kg). With full fuel of 70 U.S. gallons (260 L; 58 imp gal) the payload for pilot, passengers, and baggage is 200 lb (91 kg).[1]

The manufacturer estimates the construction time from the supplied kit as 2500 hours.[1]

Operational history

edit

By 1998 the company reported that one aircraft was flying.[1]

In December 2016, three examples were registered in the United States with the Federal Aviation Administration and one in Canada with Transport Canada.[3][4]
