Flight Design Exxtacy

The Exxtacy was intended as a high-performance rigid-wing hang glider, for competition use and two-place instruction.^[1]

The Exxtacy wing is based upon a carbon-fiber-reinforced polymer cantilever box spar, with ribs and wing tips, also of the same material. Control is by weight-shift, with roll control augmented by wing top-surface spoilers. For thermalling flight and landing, inboard flaps were installed. The aircraft achieves a glide ratio of 17.5:1.^[2]

The aircraft can be dismantled for ground transport and folds to 5.70 m (18.7 ft) x 0.26 m (0.9 ft) x 0.52 m (1.7 ft).^[2]
