Design and development

The wing is a cable-braced, king post-equipped hang glider-style wing designed as touring wing for two-place trikes. It comes in one size, the EOS 15, named for its metric wing area of 15 m2 (160 sq ft).[1]

The wing is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. The wing's crosstube is enclosed in the double surface. Its 10.48 m (34.4 ft) span wing uses an "A" frame weight-shift control bar and is equipped with spoilers.[1]
