Design and development

The Eagle was designed as an intermediate-level glider. It is made from aluminum tubing, with the mostly double-surface wing covered in Dacron sailcloth and cable braced from a single kingpost. Its nose angle is 122°.{{cite web|url = http://willswing.com/wp-content/uploads/manuals/Eagle_2nd_March_2002.pdf|title = Eagle 145,164,180 Owner/Service Manual|accessdate = 7 March 2016|author = Wills Wing|date = March 2002}}

The models are each named for their rough wing area in square feet. The Eagle was certified to HGMA and DHV standards.
