Flight F4 Racing

Introducing our newest addition to the foil family: the F4 Racing Foil.
A fully evolved, high-performance racing experience, shaped and crafted through months of development, CFD simulations and water testing. We have reduced drag by integrating the fuselage into the front wing, as well as the tail adjustment within the foil. The High Modulus Carbon construction makes it the stiffest foil ever produced.
The F4 Racing stands for power, speed, balance and control on all courses and racing formats.

FEATURES

BASE SYSTEM

Integrated carbon Deep Tuttle Base for maximum strength, elimination of movement and perfect load transfer.


CONSTRUCTION

All foils are supplied with a T-40 torx drive, and come with titanium plated stainless steel bolts for maximum strength to weight ratio, preventing any corrosion problems.

INTEGRATED WING TO FUSELAGE CONNECTION

An upgrade on regular bolt-on-wing connections, F4 Racing Foil integrates the wing and fuselage together creating unparalleled stability and improved hydro-dynamics.

The integrated design ensures that the critical leading edge of the front wing creates undisturbed flow, meaning improved lift-to-drag ratio, and faster speeds.


STAINLESS CLAMPING TAIL SYSTEM

Innovatively engineered, F4 Racing Foil eliminates the classic bolt-on tail in favor
of a more seamless design that blends the fuselage into the tail wing.
This connection technique further reduces drag,enables precise angle tail adjustment and is rock solid.

TAPERED ELLIPTICAL MAST INTO FUSELAGE CONNECTION

Unique to F4 Racing Foil, the elliptical mast progressively tapers from its thinner edge to thicker core, eliminating weakness at the critical stress point on the front edge where the down- force hits the foil. To connect fuselage to mast, we engineered a system using 3 stainless steel bolts molded into the carbon fibre. This design offers the most

effective load transfer between mast and fuselage by eliminating the typical straight-edge, and also provides a stronger mast-to-fuselage connection compared to standard drilled carbon and cross- dowel system.


PROGRESSIVELY TAPERED MAST TO BOARD CONNECTION

Progressively tapered in the area flying above the water, this newly refined mast improves strength and rigidity where it is needed most: just below the Tuttle box. Additionally, the tapered shape creates a step on the mast that sits on the underside of the board and prevents the foil from moving, thus ensuring an ultra precise angle position for board and rider.
