SF is the most simple and very safe wing for speedriding.
Suitable for take-off with or without skis.
Immediately responce to the brakes applying allows maneuvering on narrow sections during flights in the mountains. High collapse resistance makes wing more safer for the pilot at high speeds. Minimal gliding on the wing during evolution will allow you to build trajectories without losing altitude.
SF is also suitable for initial training and can be used for groundhandling and first flights.
Wing materials used:
surfaces — Skytex E25, E65
ribs — Skytex E29
rib reinforcement — SR series, nylon rods
Lines: — Liros DSL / TSL / TSL / DFLS.
