The Paxman Viper is a Canadian homebuilt aircraft that was designed by Elbert Paxman and produced by Paxman's Northern Aircraft of Glenwood, Alberta, introduced in 1994. When it was available the aircraft was supplied as a kit for amateur construction.[1]
Design and development
The Viper was designed for the Canadian advanced ultralight category. It features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration.[1][2]
The aircraft airframe is made from wood, covered in doped aircraft fabric. Its 27.00 ft (8.2 m) span wing has a wing area of 102.0 sq ft (9.48 m2). The acceptable power range is 65 to 110 hp (48 to 82 kW) and the standard engine used is a 100 hp (75 kW) Suzuki automotive conversion powerplant.[1]
The Viper has a typical empty weight of 585 lb (265 kg) and a gross weight of 1,050 lb (480 kg), giving a useful load of 465 lb (211 kg). With full fuel of 17 U.S. gallons (64 L; 14 imp gal) the payload for the pilot, passenger and baggage is 363 lb (165 kg).[1]
The standard day, sea level, no wind, take off with a 100 hp (75 kW) engine is 300 ft (91 m) and the landing roll is 400 ft (122 m).[1]
The manufacturer estimated the construction time from the supplied kit as 500 hours.[1]
Operational history
By 1998 the company reported that one kit had been sold, was completed and flying.[1]
In January 2014 one example was registered with Transport Canada.[3]
