The Avian Cheetah is a British high-wing, single-place, competition hang glider, designed by Steve Elkins and Neil Hammerton and produced by Avian Limited of Hope Valley, Derbyshire.[1][2]
Design and development
The Cheetah is a development of the Avian Java and is a "topless" design without a kingpost or top wire rigging, although it retains the lower flying wires.[1]
The current production Cheetah 150 model is made from aluminum and carbon fibre tubing, with the wing covered in Dacron sailcloth. Its 10.4 m (34.1 ft) span wing has a nose angle of 130deg; and an aspect ratio of 7.5:1. The acceptable pilot hook-in weight is 80 to 110 kg (180 to 240 lb).[1]
The glider can be broken down to a 37 kg (82 lb) package, 4.6 m (15.1 ft) in length for ground transportation on a car top.[2]
