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.
