The Finsterwalder Speedfex is a German high-wing, single-place, hang glider, designed and produced by Finsterwalder.[1]

Design and development

[edit]

The Speedfex was designed as man-packable double-surface competition glider for cross country flying. As such the Speedfex weighs only 29.5 kg (65.0 lb) and can be reduced to a folded size of 2.05 m (6.7 ft)[1][2]

The aircraft is made from aluminum tubing, with the wing covered in Dacron sailcloth. Its 10 m (32.8 ft) span wing is cable braced from a single kingpost. The nose angle is 130° and the aspect ratio is 7.1:1. The pilot hook-in weight range is 70 to 110 kg (154 to 243 lb). The glider is certified as DHV Class 2.[1]
