Design and development

The Champion V features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed or optionally retractable tricycle landing gear and a single engine in tractor configuration.[1][2]

The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its 8.321 m (27.3 ft) span wing mounts flaps and has a wing area of 11 m2 (120 sq ft). The wings are removable in about 15 minutes for ground transport or storage. The cabin width is 42 in (110 cm). The acceptable power range is 75 to 100 hp (56 to 75 kW) and the standard engine used is the 75 hp (56 kW) Volkswagen air-cooled engine four cylinder, air-cooled, four stroke automotive conversion powerplant.[1][2]

The Champion V has a typical empty weight of 272 kg (600 lb) and a gross weight of 480 kg (1,058.2 lb), giving a useful load of 208 kg (459 lb). With full fuel of 49 litres (11 imp gal; 13 US gal) the payload for the pilot, passenger and baggage is 173 kg (381 lb).[1]

The manufacturer estimates the construction time from the supplied kit as 1500 hours.[1]

Operational history

By 1998 the company reported that 15 kits had been sold and three aircraft were completed and flying.[1]

In January 2014 one example was registered in the United States with the Federal Aviation Administration.[4]
