FCS SF4 Stretch Quad Fins

**The NEW FCS Stretch Quad PC Fins are here! FCS has enhanced the SF4 Stretch Quads (Tri, Quad and 5-Fin) with their ground breaking Performance Core Material! Get them before they sell out! (And they will)

The FCS SF4 Stretch Quad Fins design features a moderate foil on a wide base, which help to generate significant speed from the initial turn, and a neutral foil along a thin, flat tip. At low speeds, the ample surface area in the tip of the FCS Quad SF4 Fins provides power, giving you the ability to generate speed with ease. With the FCS Stretch Quad Fins as speed increases, applied force will allow the thin tip to twist with the flow (much like a birds wing in flight) becoming neutral while reducing lift and drag through turns. These cambered foils were developed using a NACA (National Advisory Committee for Aeronautics) foil in combination with theories taken from sailboard sails. With years of fin experience Stretch foiled the first prototypes of the Quad SF4 himself. The result on your Quad is a board that is free yet stable at high-speed turns. And all these characteristics are enhanced in Performance Core!
