Unlike traditional designs that balance between lift and drag, Armstrong’s HA front wings aim for an aggressive glide-to-lift ratio while maintaining composure at speed. These wings feature thin camber lines, optimized taper, and a progressive twist distribution from root to tip—resulting in stable yet reactive lift across a broad velocity range. Furthermore, anhedral shaping in the wing tips provides dynamic roll stability, especially during aggressive carves and yaw-loaded transitions. The result is a wing that slices cleanly through chop, maintains efficient flow, and tracks like a missile on downwinders. Carbon Layup Technology Armstrong uses high-modulus carbon fiber exclusively in the HA Kit, laid up with proprietary orientation strategies. This maximizes torsional stiffness without adding unnecessary mass. Every layer is tuned for structural harmony: longitudinal fibers offer rigidity under load, while transverse sheets provide durability and shock absorption. The advantage? Immediate feedback through your feet. When you engage the foil—whether to pump, carve, or drop in—the power transmission feels direct, fluid, and precise. Fuselage Integration and Tapered Fit The carbon fuselage utilizes a double-tapered junction with the front wing for zero play and maximum load distribution. Paired with titanium inserts at all connection points, this system is bombproof and rattle-free. Additionally, the embedded spine distributes hydrodynamic pressure evenly, preventing wing flutter and ensuring smoother water release at all speeds. In real-world testing, the fuselage proved capable of withstanding abrupt pitch changes and high-speed yaw inputs without vibration. For racers and performance-focused riders, this delivers consistent control with every push. Hydrodynamic Efficiency Thanks to Computational Fluid Dynamics (CFD) and thousands of hours in ocean testing, the Armstrong HA wings achieve remarkably low drag coefficients. Whether foiling on flatwater lakes or charging open-sea swells, the wings maintain lift with minimal energy input. Moreover, tip ventilation is reduced through elliptical wing planforms and negative dihedral shaping. This reduces drag during turns and enhances the rider’s confidence to lean deeper, bank harder, and recover faster.  Use Case Analysis — Downwind, Race, Wing, and Prone Foiling Downwind Gliding: Efficiency That Lasts for Miles In open-ocean or lake-based downwind runs, the Armstrong HA Foil Kit offers unrivaled glide. With high-aspect wings like the HA1080 or HA1180, riders can link swell after swell without exhausting themselves. The low-drag profile cuts through texture, and the stability ensures tracking with minimal correction. Additionally, the glide ratio allows you to stay high on bumps longer, minimizing the need for paddle input or excessive pumping. Riders can maintain energy over long distances—ideal for distance missions and big water exploration. Race Performance: Maximize Velocity Made Simple Competitive racers demand gear that delivers optimal VMG (velocity made good), and Armstrong’s HA Kit is built for speed. The thin foil sections and long-span wings drastically reduce induced drag, allowing for higher top-end speeds without control loss. Paired with a longer carbon mast and narrow stabilizer, racers can maintain upwind angles and downwind control in heavy wind. Even in choppy waters, the foil tracks with razor precision. Wing Foiling: A Perfect Blend of Lift and Speed Wing foilers will appreciate the Armstrong HA Foil Kit’s early lift and long glide. Whether you’re using it in lighter conditions with larger wings or aiming for high-speed cruising in 25+ knots, this kit provides dependable, predictable response. The HA880 and HA980 wings, in particular, balance speed with maneuverability, giving riders the ability to boost, gybe, or transition effortlessly without stalling. Prone…
