Evolution of the V8 three-strut platform: redesigned wingtip and leading-edge shape for smoother turning and better twist/stability, a fine-tuned aspect ratio for more low-end power, lift and hangtime, stronger leading-edge Dacron, and a new two-panel 'lean strut' construction (lighter and stronger). Adds a canopy protector at the valve, a faster inflate/deflate valve, a Ronstan sheaveless pulley, and 3 m line-extensions on the 14 and 16 m.
