It features vertical winglets at the wingtips which help lock the yaw at high speed. The profile we selected features a low drag coefficient whilst giving us unmatched pitch stability. If you want to ride fast while keeping full control, you need our new R190 stab.Do not hesitate to play with our shims to fine tune your ride. More experienced riders will want to use the negative 0.3 or 0.6deg shims to reduce the angle of attack of the stab and lower the drag to a minimum, specially if being used in combination with our new 47cm tail and forth screw.
