The aircraft's 15.1 m (49.5 ft) span wing has 72 cells, a wing area of 43 m2 (460 sq ft) and an aspect ratio of 5.3:1. The pilot weight range is 160 to 210 kg (353 to 463 lb). The glider is DHV 1-2 Biplace certified.[1]

The design progressed through three generations of models, the Twin, Twin 2 and Twin 3, each improving on the last.[1]
