Design and development edit
The aircraft was designed as a beginner glider for school flight training use. The models are each named for their approximate wing area in square metres.[1]
The design features pitch control stability to simplify beginner ground handling. Also the cells decrease in width towards the wing tips to improve turn co-ordination.[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 in diameter. The risers are made from 25 mm wide polyester strapping.[3]
