Design and development
The aircraft was derived from the Best Off Skyranger and designed to comply with Canadian Advanced Ultralight criteria and the US light-sport aircraft rules. It features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit with optional doors for access, fixed tricycle landing gear or optionally conventional landing gear and a single engine in tractor configuration.
The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in Dacron sailcloth. Its 9.6 m (31.5 ft) span wing has an area of 13.25 m2 (142.6 sq ft) and mounts flaps. Standard engines available are the 64 hp (48 kW) Rotax 582 two-stroke, the 80 hp (60 kW) Rotax 912UL and the 100 hp (75 kW) Rotax 912ULS four-stroke powerplants.
The Cheetah XLS has been accepted by Transport Canada as an Advanced Ultralight as both a land plane and seaplane, powered by the Rotax 582 two-stroke, the Rotax 912UL, the Rotax 912ULS, the Verner VM133 and the 85 hp (63 kW) Jabiru 2200A engines.
