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°.[1][2]

The models are each named for their rough wing area in square feet. The Eagle was certified to HGMA and DHV standards.[1][2]
