The Rainbow Cheetah a South African ultralight and light-sport aircraft, designed by Vladimir Chechin and produced by Rainbow Aircraft. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.^[1]

Design and development

The aircraft was derived from the Best Off Skyranger^[1] 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.^[1][2]

The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in Dacron sailcloth. Its {{convert|9.6|m|ft|1|abbr=on}} span wing has an area of {{convert|13.25|m2|sqft|abbr=on}} and mounts flaps. Standard engines available are the {{convert|64|hp|kW|0|abbr=on}} Rotax 582 two-stroke, the {{convert|80|hp|kW|0|abbr=on}} Rotax 912UL and the {{convert|100|hp|kW|0|abbr=on}} Rotax 912ULS four-stroke powerplants.^[1]

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 {{convert|85|hp|kW|0|abbr=on}} Jabiru 2200A engines.^[3]

Operational history

By August 2012 there were three Cheetahs on the Federal Aviation Administration registry and two on the Transport Canada Civil Aircraft Register.^[4][5]

Variants
