The Twist was designed as a beginner hang glider and is built in three sizes.[1]
Typical of the series, the Twist 15 is made from
aluminum tubing, with the wing covered in
Dacron sailcloth. Its 9.2 m (30.2 ft) span wing, uses a single tube-style
kingpost and upper
flying wires. The nose angle is 120° and the
aspect ratio is 6.5:1. The model number indicates the approximate wing area in square metres.[1]
