 Wing Design, Materials & Hydrodynamics

Advanced Foil Profiles for High-Speed Stability

At the core of the HA Kit lies its ultra-refined wing profile. 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 Surf Foiling: Control at Speed, Lift in Turns

For prone surfers, control and early lift are essential. The smaller HA wings (580–780) deliver punchy pop on takeoff while maintaining composure in steep, fast-moving waves. These wings allow you to draw longer lines, bank harder in critical sections, and stay connected during fast down-the-line runs.

Because of the kit’s stiffness and low weight, pumping back out is efficient. The foil maintains flow through each pump cycle, helping surfers reposition quickly.

 Mast & Fuselage Architecture and Load Distribution

Carbon Mast Construction for Rigidity and Control

Armstrong’s carbon masts are precision-engineered to balance strength, stiffness, and responsiveness. Each mast begins with a high-modulus carbon fiber core that is pressure molded for maximum consistency. The layup orientation—aligned at 0°, ±45°, and 90° fiber angles—ensures torsional rigidity and minimizes unwanted flex under load.

Whether using the 72cm for prone and surf, or the 85cm and 100cm masts for race and wing, riders experience predictable mast response across a full range of water conditions. The stiffness of the carbon structure eliminates wobble, making even small trim adjustments feel immediate.

Hydrodynamic Profile and Tapered Form

The mast profile has been optimized using both computer modeling and real-world trials. It tapers gradually from base to head, offering minimal frontal drag while maintaining lateral resistance. This allows riders to engage the mast like a blade—cutting cleanly through chop while maintaining upright control at speed.

Additionally, the mast’s leading edge is shaped to reduce cavitation and delay ventilation in rougher conditions, allowing more aggressive angles during transitions and carves.

Fuselage Stress Distribution

At the heart of the HA system lies the carbon-titanium fuselage, a masterclass in load distribution. Rather than concentrating stress at the mast-to-fuselage joint, Armstrong uses a titanium spine that extends into the fuselage body. This distributes pitch and torsional loads evenly along the carbon length, preventing hotspot fatigue.

The result? Reduced material degradation over time, even with heavy use and powerful water impacts.

Tail Wing (Stabilizer) Options and Tuning for Ride Feel

Why the Stabilizer Matters More Than You Think

In foil dynamics, the tail wing—commonly known as the stabilizer—is the unsung hero. While the front wing gets all the attention for lift and glide, it’s the stabilizer that balances pitch, fine-tunes responsiveness, and shapes your turning behavior. The Armstrong HA Foil Kit offers multiple tail wing (stab) options that empower riders to adjust feel, ride position, and control dynamics with surgical precision.

Whether you’re seeking locked-in tracking at high speeds or nimble pitch reactivity for surf-style maneuvers, selecting the right stab changes everything. Even minor variations in stabilizer size, angle, or placement can redefine your experience on the water.

Armstrong HA Tail Wing Options — Overview

To accommodate every riding style and skill level, Armstrong offers three key tail wings that are compatible with the HA Foil Kit:

• ✅ HA180 Stabilizer – Maximum glide, minimal drag

• ✅ HA195 Stabilizer – Balanced blend of control and efficiency

• ✅ HA210 Stabilizer – Increased pitch stability and lift

Each of these has been meticulously shaped and tested alongside the HA front wings. They’re not just interchangeable—they’re integral to the holistic foil system.

Let’s explore the specific tuning benefits of each.

HA180: Speed & Glide Prioritized

For advanced foilers, especially those racing or downwinding, the HA180 is a go-to choice. Its thin profile and shorter span generate minimal drag, enabling you to reach top speeds with ease. Furthermore, it offers a looser, more agile feel that advanced riders love when carving at high velocities or connecting bumps with fluid transitions.

However, due to its reduced surface area, the HA180 requires refined pitch control and timing. Therefore, it’s ideal for riders who already have strong muscle memory and balance on foil.

Key Characteristics:

• Lowest drag of the HA stabs

• Best for advanced speed or race setups

• Looser pitch feel with quicker roll transitions

• Pairs well with HA680, HA780, and HA880

---

HA195: The All-Rounder

The HA195 stabilizer is arguably the most versatile in Armstrong’s lineup. It delivers a harmonious balance between control and glide. As a result, this makes it the perfect choice for all-around foilers—whether you’re winging, prone surfing, or casual downwinding.

Additionally, its moderate surface area provides enough lift to keep the foil level during pumping while not over-controlling the ride. This makes it a natural pairing with nearly any front wing in the HA range.

Key Characteristics:

• Well-balanced lift and glide ratio

• Predictable feedback in variable conditions

• Smooth turns without sacrificing top-end speed

• Matches well with HA780 through HA1080

---

HA210: Control and Stability Enhanced

For riders who prioritize locked-in tracking, especially in bumpy water or with larger wings, the HA210 is essential. It provides strong pitch stability and extra lift at lower speeds. As a result, beginner and intermediate riders may find the HA210 more comfortable when progressing into higher-aspect setups.HA Foil Kit

Because of its surface area, the HA210 allows for longer pump cycles and easier transitions in low-power scenarios. While it introduces a touch more drag, the stability payoff is often worth it—especially in surf foil and learning environments.HA Foil Kit

Key Characteristics:

• Highest stability in the HA stab range

• Best for early lift and confidence in chop

• Adds pitch forgiveness during turns

• Excellent with HA1080 or HA1180

HA Foil Kit Tuning with Shims: Fine-Tune Your Ride Feel

Besides swapping tail wings, Armstrong’s HA Kit supports micro tuning via shims—thin angled inserts that adjust the stabilizer’s angle of attack (AoA). By adding or removing shims (typically in 0.5–1° increments), riders can tweak how the foil behaves under load.HA Foil Kit

What Shim Adjustments Affect:

• Negative Shim (-0.5° to -1.5°)
  Reduces lift from the tail, speeds up ride, loosens pitch

• Neutral Shim (0°)
  Balanced response for most riders and uses

• Positive Shim (+0.5° to +1.5°)
  Increases tail lift, improving control and pump response

It’s important to note that shimming affects not just pitch stability, but also energy efficiency during pumping and maneuver control. While advanced riders often favor negative shims for looser feel, newer riders may benefit from a slight positive angle to help with stability and lift.HA Foil Kit
