RSX ULTRA 730 AR17.2 Pure glide experience

Downwind and wingfoil champions will love this new foil wing, and not just them.

The RSX Ultra is the foil wing with the highest aspect ratio ever manufactured to date: AR 17.2.

With over fifteen years of expertise in manufacturing and designing hydrodynamic profiles, along with very high-quality materials, Alpinefoil presents this foil wing that shakes up the world of downwind and performance with its unique glide, excellent maneuverability, and in-flight tolerance that makes it accessible.

This RSX Ultra is a technological marvel designed to deliver performance to a wide audience. In downwind paddling, it will allow for very high average speeds thanks to the perfect combination of a low surface area and a next-generation profile that ensures stable flight at both low and high speeds with great ease.

The final production version of the RSX Ultra features a specially designed arch that allows the tips to lift out of the water without creating ventilation.

In wingfoiling, the RSX Ultra is remarkable. It guarantees a smooth glide over even the slightest bumps with impressive ease.

Jibes are easy, and takeoff is very quick for this surface. The upwind performance is astonishing, with a very high speed along the axis. Takeoff is straightforward and resembles that of a 900 in classic ratio in terms of ease, rather than a 700.

This will especially delight freefly enthusiasts, as it's its preferred domain. However, it is equally impressive on flat water in both wingfoil and windfoil. Its incredible glide makes it completely addictive, as the wing cuts through the water with a unique smoothness.

The RSX Ultra embodies glide in its purest form.

Alpinefoil, a French-made forward-compatible multidisciplinary design

In recent years, we've seen a real game-changer in foil sports. Nowadays, practitioners are multidisciplinary: they do wingfoiling, kitefoiling, windfoiling, downwind SUP foiling, and even pump foiling.

For this reason, Alpinefoil’s philosophy focuses on compatibility with all foils across all the disciplines of our brand. When we develop a new wing, we always take a cross-disciplinary approach. This means that the wings we design can be used for both wing foiling and other foil disciplines. Of course, they might be slightly more tailored to a specific discipline based on their characteristics, but fundamentally, everything is designed to ensure they perform well across various practices.

Moreover, all our wings are designed to be compatible with all the brand's stabilizers. The choice of stabilizer will depend solely on your preferences, skill level, and what you're looking for.

Designing foils: the impact of aspect ratio on performance!

What is the aspect ratio (elongation) of a foil wing?

The aspect ratio, like the area or wingspan, is one of the key characteristics of an airplane wing or a foil wing.

The aspect ratio of a wing is a term used in aerodynamics and sail design to describe the relationship between the wingspan (the distance between the tips of the wings) and the wing area. It's calculated using the following formula:

A high aspect ratio means that the wing is long and narrow, while a low aspect ratio indicates that the wing is shorter and wider.

Implications of the aspect ratio:

Performance: Wings with a high aspect ratio tend to provide better lift and reduced drag in the air/water, which can improve efficiency and speed.
Maneuverability: Wings with a lower aspect ratio are generally more maneuverable and responsive, which can be desirable in disciplines like freestyle or surfing.
Stability: A high aspect ratio can also contribute to better stability in flight, while a lower aspect ratio may make the wing more sensitive.
In summary, the aspect ratio is a key factor in wing design, affecting performance, maneuverability, and flight behavior.

Alpinefoil, the only foil manufacturer to keep backward compatibility of its wings across all disciplines!

We’re committed to not repeating the mistakes of the past, especially those we encountered during our windsurfing days. Over the years, some board brands have changed how their fins connect, forcing users to switch boards just to use the latest fin models.

When we started designing and manufacturing our foils, our top priority was to create a universal fuselage/wings connection system that could accommodate nearly any foil wing shape out there.

Thanks to this mindset we kicked off back in 2010, all wings designed since then are compatible with all our foils. This approach makes Alpinefoil the only brand to have adopted such a compatibility-saving strategy, ensuring that your investment won’t lose value due to compatibility issues. It’s worth mentioning that some used foils currently lose up to 90% of their value simply because the manufacturer didn’t maintain backward compatibility.
