Armstrong S1 Alloy Foil Kit

The Step 1 (S1) foil range redefines how we learn to foil, offering remarkable stability, ultra-low flying speed, and an instantly intuitive feel to make that first step into foiling as easy and forgiving as possible. Pitch, roll, and yaw stability are critical to success in building foiling skills, and the S1 design achieves a near autopilot level of predictability thanks to a combination of leading and trailing edge curvature, chord length, and foil section geometry. The result is an ultra-easy platform for first-time flyers to learn any foil discipline. S1 foils fly at remarkably low speeds with high levels of controllability, allowing riders to practice maneuvers with less risk and a shorter learning curve. When overloaded, the foil reduces breaching and tends to fly back down when approaching the surface. Since these foils handle speed and ventilation so well, riders of any size can enjoy an exceptionally wide usable speed range. Downward curving wingtips provide an extra element of safety. The kit consists of a 72cm Aluminum Mast, a 75cm Aluminum Fuselage, an S1 300 Stabilizer, and a kit bag. Details An ultra-easy platform for first-time flyers to learn all foil disciplines. Excellent low-speed lift, stability, and ventilation recovery. The curvature of the leading and trailing edges provides stability and a narrower span to minimize breaches. Downward curving wingtips enhance rider safety and improve water flow efficiency. Armstrong A+ System’s proprietary foil connection design provides industry-leading stiffness, durability, and modularity. The S1 300 stabilizer was developed alongside the S1 foils to provide riders with the best possible learning platform.
