The Wills Wing U2 is an American high-wing, single-place, hang glider, designed and produced by Wills Wing of Orange, California since 2003. The aircraft is supplied complete and ready-to-fly.^[1]

Design and development

The U2 was conceived as a recreational intermediate glider with performance nearing that of competition gliders, like the Wills Wing T2. The U2 is made from 7075 aluminum tubing, with the 84% double-surface wing covered in Dacron sailcloth. The U2 includes a variable geometry (VG) system that tensions the sail for higher glide performance.^[1]^[2]

The two models available are each named for their wing area in square feet.^[1]

The glider is also sold by Tecma Sport of France as the Techma Sport U2.^[3]
