The glider also features an unusual side-stick control system to accommodate the pilot in its unusually narrow cockpit. As the maximum possible water ballast that can be carried in the wings is almost 60 kg (130 lb) heavier than the empty weight of the glider, the Diana 2 has a very large range of wing loadings, from 28 to 58 kg/m2 (5.7 to 11.9 lb/ft2).Diana Sailplanes: DIANA 2 – accessed 2008-08-26
