Take to the air with the all-new RS:FLIGHT F4 from NeilPryde — an experience like nothing else. The RS:FLIGHT F4 foil is a no-compromise, performance carbon foil designed in collaboration with F4 USA.The RS:FLIGHT F4 is an evolution of the proven F4 windsurf hydrofoil design, already considered as the best wind-foil in the market with unmatched hydrodynamics.The RS:FLIGHT F4 has very stiff construction and low drag allowing the rider to use every gust for acceleration. It is delivered with two front wings for two flight modes: the High Lift Wing combines early take off and exceptional upwind performance with amazing stability, while the High Speed Wing delivers maximum speed and acceleration.
RS:FLIGHT F4. There’s something in the air.
Integrated and carbon Deep Tuttle Base for maximum strength, elimination of movement and perfect load transfer.
Seven stainless steel boilts for maximum strength to weight ratio while preventing any corrosion problems.
This feature minimizes the drag at the end of fuselage and provides a very strong connection through opposing screws countered in tension. There is also +/- 1.5 degree (total 3degree) adjustability available by changing the tension of the front top and bottom screws. Foil is perfectly trimmed for average weight sailor (75-80kg) with tail in neutral position. Heavier sailors, especially with large front wing in light winds or during learning process might prefer slightly more stabilizing force that down tilted rear wing provides. At the same time lighter sailors, especially in strong wind conditions might find a neutral position creates excessive lift and will reduce the differential angle between two wings by tilting the tail slightly up.
At the most critical loading stress points (shaft leading and trailing edge-to-fuselage connections), we maintained large radius in the corners. This has a benefit of distributing tremendous compression forces existing in this area while at the same time creating a very smooth shape which minimizes turbulences common to hard edges.
