Design and development

The Funfex and the smaller-sized Airfex are intended as man-packable double-surface intermediate gliders for recreational cross-country flying. As such the Funfex weighs only 24 kg (52.9 lb) and can be reduced to a folded size of 1.95 m (6.4 ft)[1][2]

The aircraft is made from aluminum tubing, with the wing covered in Dacron sailcloth. Its 9.4 m (30.8 ft) span wing is cable braced from a single kingpost. The nose angle is 120° and the aspect ratio is 5.5:1.[1]
