Avian Cheetah
# Avian Cheetah

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.

## 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.

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).

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.
