Design and development

The Prymus was designed as a beginner to intermediate glider. By 2016 the design had progressed through four generations of models, the Prymus 1, 2, 3 and 4, each improving on the last. The models are each named for their relative size.[1]

The Prymus 4 has a top and bottom wing surface made from WTX 40 - 40 g/m2 fabric, with wing ribs made from Pro Nyl 42 g/m2 rip stop covered with poliuretano and BT technology reinforcements. The lines are 1.1, 1.5 and 2.1 mm Cousin Technora Superaram, while the risers are Fitanew 15 x 2,0 mm Flat Multi 1600 kg strapping. The carabiners are Ansung Precision 4mm 800 kg and the pulleys are made by SOL.[2]
