Design and development

The aircraft was designed as a competition glider. The models are each named for their approximate wing area in square metres.[1]

The design was optimized for glide ratio and maintenance of wing tip pressure to prevent collapses.[2]

The glider wing is made from Porcher Marine Skytex 44 g/m2 nylon fabric. The rib reinforcements are 310 g/m2 Dacron, with the trailing edge reinforcement fabricated of 175 g/m2 polyester. The lines are all sheathed Kevlar of 1.1 and 1.7 mm diameter or, optionally 0.6 and 0.9 mm micro unsheathed lines. The risers are made from 20 mm wide Polyamida strapping.[3]

Operational history

Reviewer Noel Bertrand praised the glider in a 2003 review, saying, "the flight qualities of the Nitro are explosive!"[1]
