Goals of the V3 Range:

• Deliver ultra-high-performance foils tailored to each discipline.
• Provide absolute tolerance and a stable, dependable feel, even in turbulence.
• Maximize lift to enable the use of smaller, more responsive, and faster surfaces.
• Simplify assembly, enhance rigidity, and reduce drag.
• Push composite rigidity and durability to the limit for superior performance.

Changes compared to V2:

• Transition from a square fuselage to an ovoid section: improved hydrodynamics, 12% drag reduction.
• Constant profile on the front wings for uniform lift.
• Streamlined design for transitions between sections (fillets), making the foil smoother. Achieved a 50% drag reduction on the lower 10 cm of the masts!

Optimization of wing profiles:

• The constant profiles from the center to the tips on the V3 allow for maximum and consistent lift, providing better control on the surface when, for instance, a tip emerges, and offering excellent low-end performance.
• The wing design has been adjusted to reduce surface turbulence, making the foil quieter and significantly more stable.
• The alignment of the planes and profiles has significantly reduced the stabilizers' surface area, consequently reducing drag.
• The new profiles rise without generating pitching at low speeds. V3 foils take off flat, making them much easier to handle, particularly during re-engagements.

Impact on performance:

• Improved stability in turns, increased rigidity for tricks and fast runs.
• Excellent low-end range and highly stable behavior in complex situations: tip-out, high-speed stalls, re-pop, turbulent water, etc.
• Reduced drag enables easier glide and sustained speed over long distances without effort. Requires 200 cm² less on the front wing.

Lightness:

• The weight of the foils has been significantly reduced (e.g., 40g less on the fuselage, 700g less on a Sirus), making transport easier and also improving responsiveness on the water.

Rigidity and durability:

• The new ovoid section of the fuselage improves rigidity by 30% compared to square versions. This ensures greater stability, especially at high speeds or during rapid transitions.
• The rounded design of the connections between flat surfaces reduces stress points, significantly increasing break resistance by 30%.
• Materials such as reinforced aluminum for the fuselage and carbon for the wings offer an excellent weight-to-rigidity ratio.

Glide and lift performance:

• Thanks to a constant profile on the front wings, lift is enhanced, allowing for a 200 cm² reduction in wing size while maintaining the same lift as a larger wing from the V2 version.
• The V3 wings are designed to minimize drag and maximize glide, a major focus of their development.
• V3 wings offer much greater tolerance, making flight easier even at low speeds. They no longer stall abruptly when approaching the surface or when a tip emerges.

Q: What is the difference between the V2 and V3 fuselages?
A: The main difference lies in the shape of the fuselage (square for V2, ovoid for V3), which reduces fuselage drag by 12% and improves rigidity by 30%. V3 fuselages are also lighter, and the wings provide similar lift with a surface area reduction of about 200 cm².

Q: How do I choose the size of my front wing?
A: The size of the front wing depends on your skill level, weight, and desired activity, but you should opt for a wing that is 200 cm² smaller than the V2 equivalent.

Q: What is the self-tightening interlocking system?
A: This system uses a triangular shape for the connections of the front wing and stabilizer. Once in place, the foil naturally tightens during use, eliminating the need for frequent screw adjustments. It remains easy to disassemble.

Q: Are V2 and V3 parts compatible?
A: Yes, thanks to adapter fuselages, users can upgrade their equipment without replacing everything. The price of an aluminum fuselage is €59, making the adaptation cost reasonable.

Q: Is the new ovoid fuselage more fragile than the previous square one?
A: No, on the contrary. The V3 ovoid fuselage is 30% stronger than the old square model due to better force distribution and a more robust shape.

Q: What is the difference between the V2 and V3 front wings?
A: The wings provide similar lift with about 200 cm² less surface area. The key innovation is in the glide performance. The foil glides much better and requires a smaller stabilizer, making it more playful and faster. The entire system is significantly more rigid.

Q: What are the benefits of a constant profile on a front wing?
A: A constant profile ensures consistent efficiency across the entire span of the wing. This makes flight more predictable and allows for a smaller front wing without losing lift, enhancing maneuverability and speed. The constant profile also enables a tip to exit the water without causing the foil to stall. Its overall behavior is much more stable.

What type of foil is best for beginners?
The X-Over V3 is designed for beginners with its high lift and tolerance, making it perfect for learning safely.

What size of front wing should I choose based on my weight and skill level?
For the V3, reduce the surface area by about 200 cm² compared to the V2. Choose a larger surface for light wind and stability, and a smaller one for maneuverability and speed.

What is the impact of the aspect ratio on the foil's behavior?
A high aspect ratio promotes glide and speed (ideal for freefly and racing), while a moderate ratio offers more tolerance and a good balance between maneuverability and stability (e.g. Curve V3).

How can I optimize the foil's placement on the board?
Moving the foil slightly forward in the box increases lift, ideal for light wind. Moving it back improves stability and control at high speed.

How do I choose the stabilizer for my front wing?
Ideally, use stabilizers and front wings from the same range, but you can mix them to adjust the character of your foil (e.g. Fluid stab with Curve front wing for more glide).

What are the advantages of an elliptical vs. rectangular outline?
The elliptical outline is more maneuverable, perfect for surfing (e.g. Fluid V3), while the rectangular outline favors stability, ideal for beginners.

What size stabilizer should I use with my front wing?
Typically, match the same size (e.g. L with L), but for a more technical effect, reduce or increase the stabilizer to adjust the foil's self-stability and lift.

How do I maintain my foil to prolong its lifespan?
Rinse with fresh water after each session, regularly check the condition of screws and connections, use Tikal, and store in a dry place away from sunlight.

Which foil is best for light wind?
The Sirus V3 is optimized for light wind with exceptional lift, followed by the Veloce HDW for speed in light winds.

How do the dihedral and curvature of the wings influence the foil's behavior?
A positive dihedral (tips up) improves maneuverability; a negative dihedral (tips down) favors stability and grip in turns.

What is the stall speed and why is it important?
The stall speed is the minimum speed to maintain flight, which varies from one foil to another and depends on the rider's ability to control the foil. A low stall speed (e.g. Sirus V3) is crucial for light wind and pumping.

How do I choose a foil for surfing vs. freestyle?
The Fluid V3 is perfect for surfing with its maneuverability, while the Ypra Surf Freestyle is ideal for freestyle moves with great pop and repop.

Can I mix different front wings and stabilizers in a quiver?
Yes, you can/should mix ranges to adjust performance, but respect the program of the front wing. Pair stabilizers to modulate maneuverability, glide, or lift based on your goal.

What is the difference between standard and high aspect ratio models for freefly and racing?
A high aspect ratio provides better glide (e.g. Ypra Race V3), while a moderate ratio offers optimal tolerance (e.g. Curve V3).

What mistakes should I avoid when buying a foil?
Don't choose a foil that's too technical or sized incorrectly for your level. Opt for wings with a program suited to your goals and a stabilizer that complements the front wing.

Is it possible to repair a foil if it gets damaged or cracked?
Yes, composite foils can be repaired. Professional service is often needed for optimal repair. Our GONG Factory workshop ensures perfect maintenance.

How do I choose a foil for downwind?
Opt for a front wing with a high aspect ratio and an appropriate surface, such as the Veloce HDW or Sirus V3 for downwind with good performance in low energy.

What are the differences between the manufacturing technologies of foils?
GONG V3 foils use prepreg composites made of carbon or fiberglass, baked under very high pressure for great strength and dynamism, optimizing rigidity and weight for each range.

What foil quiver should I have for a wide range of use?
A good quiver includes a Sirus V3 front wing for light wind, a Curve V3 for freeride and waves.

What tips can help me take off more easily in light wind?
Use a front wing with a larger surface for lift (e.g. Sirus V3), move the foil forward a bit (1-2 cm) in the box, and choose a 5m² or larger wing for more traction. Most importantly: go for a Cruzader, which will change your approach to light wind.
