Design and development

The Choice Zip Bi was designed as a tandem glider for flight training and as such the Bi designation indicates "bi-place" or two seater.[1]

The "Zip" name indicates that a zipper is included in the wing to reduce wing area when required.[1]

The aircraft's 14.2 m (46.6 ft) span wing has 54 cells, a wing area of 54 m2 (580 sq ft) and an aspect ratio of 4.95:1. The pilot weight range is 110 to 180 kg (243 to 397 lb). The glider is DHV 1-2 Biplace certified.[1]
