{"product_id":"armstrong-s1-foil-kit","title":"Armstrong S1 Foil Kit","description":"\u003cp\u003eArmstrong's S1 (\"Step 1\") Foil Kit is genuinely the easiest way to start foiling — designed from the ground up for first-time flyers who want stability, predictability, and a forgiving learning curve over outright performance. Four front wing sizes from a manoeuvrable 1250cm² to an ultra-stable 2450cm² mean there's a right S1 for every learner regardless of weight, board, or conditions. The complete kit includes everything you need to start: S1 front wing in your chosen size, S1 300 stabiliser, 72cm alloy mast, 75cm alloy fuselage, mast top plate, all hardware, and a kit bag — ready to bolt on to any compatible foil board. The S1 has been the foil that's converted more first-time foilers in North Wales to the sport than any other shape in the Armstrong line. From £1,279 — free UK postage.\u003c\/p\u003e\n\u003ch2\u003eStep 1: Redefining How We Learn To Foil\u003c\/h2\u003e\n\u003ch3\u003eProduct overview\u003c\/h3\u003e\n\u003cp\u003eThe Step 1 (S1) foil range delivers remarkable stability, ultra low flying speed and an instantly intuitive feel to make the first step into foiling as accessible and forgiving as possible.\u003c\/p\u003e\n\u003cp\u003ePitch, roll and yaw stability are critical to success when building foiling skills. The S1 design achieves a near autopilot-like level of predictability thanks to a combination of leading and trailing edge sweep, chord length and foil section geometry. The result is an ultra easy platform for first time flyers to learn any foiling discipline.\u003c\/p\u003e\n\u003cp\u003eThe S1 foils fly at a remarkably low speed with a high degree of controllability so that riders can practise manoeuvres with less risk and a lower learning curve. When overpowered, the foil reduces breaching with a tendency to fly itself back down when approaching the surface. Because these foils handle speed and ventilation so well, riders can enjoy an exceptionally broad usable speed range in each size.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eUltra-easy learning platform.\u003c\/strong\u003e An ultra easy platform for first time flyers to learn any foiling discipline.

Best for lighter riders (50–75 kg) or those who've already had a few sessions and want to refine their skills. Good for front wave foiling and more advanced manoeuvres as confidence builds.

Best for intermediate riders 70–85 kg wanting versatility — pumps and glides well, forgiving through turns and transitions. Many advanced foilers also keep a 1550 for lighter wind days.

If you're new to foiling and unsure which size to choose, this is the safe bet for riders 75–95 kg.

Best for heavier riders over 95 kg, riders learning in genuinely marginal wind, or anyone wanting to extend the lower end of their wind range. Gets riders flying earlier than any other Armstrong wing.

We could sell you a more performance-oriented foil (HA, MA, APF) but if you're new to foiling those foils will be punishing while you learn, and the S1 will get you flying in days instead of weeks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich size?\u003c\/strong\u003e For most learners we recommend the 1850 at £1,349 — it's the size that suits most adult riders (75–95 kg), has the lowest stall speed in the range, and gives you the maximum margin for error while you're learning. If you're lighter than 75 kg, look at the 1550 (£1,319). If you're heavier than 95 kg or learning in very light wind, the 2450 (£1,369) is worth the extra. The 1250 (£1,279) is best left until you've already had a few sessions on something larger — it'll be twitchy as a first foil.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBoard compatibility.\u003c\/strong\u003e The S1 kit fits any board with a standard Armstrong A+ System foil track (most modern wing foil boards).
