What Airush has to say about the Ultra V4
- Ultimate lightweight design for foil, freeride & surf.
- Unique combination of stability & responsive drive.
- High-performance, lightweight Single Strut Geometry.
When it comes to finding the ultimate combination in lightweight performance design for foil, freeride, and surf, look no further than the Ultra. The unique blend of stability, low end power, and responsive drive allows the kite to fly further forward in the window. Pairing lightweight Single Strut Geometry with a higher tension canopy makes this the most responsive version yet.
- Lightweight Single Strut Geometry
- Improved canopy tension & rigidity to increase responsiveness
The emergency safety handles are provided on each wingtip. This maximizes the control and security when performing a self-rescue.
LIGHTWEIGHT SINGLE STRUT GEOMETRY
The Ultra V3 is designed to maintain its shape and responsiveness by maximising the benefits of the unique Airush Load Frame. The balanced geometry combines canopy curve, leading edge sweep and a specific trailing edge concave.
By reducing the number of struts and combining this with WebTech smart reinforcing the weight of the Ultra V3 is minimised. This enables a greater level of performance in all wind conditions and allows us to push the boundaries of light wind performance.
REAR LINE ADJUSTMENT
The rear lines affect the turning speed of the kite. By moving the rear lines towards the leading edge, the kite becomes static and stable, perfect for wave riding. Moving the rear lines towards the trailing edge allows the kite to move faster, perfect for foiling.
AIRUSH LOAD FRAME V4 FEATURING WEBTECH
The Airush Load Frame, featuring WebTech, has been the key to setting the ultimate benchmark in durability without compromising on weight. By expanding our exclusive Load Frame with WebTech throughout the areas normally occupied by Dacron, we are able to minimize or completely remove the heavier fabric, and utilize the ballistic high-modulus polyethylene web fibers instead – increasing strength and minimizing weight.
WebTech minimizes or replaces the traditional Dacron reinforcement by channeling the broader loads into the Load Frame through a web ‘subframe’ of Ultra High Molecular Polyethylene (Ultra High Modulus). This is featured in key areas such as the primary attachment points on the leading edge or the rear attachment points, while also being used to support structural components such as the center strut.
V3.2 BRIDLE SYSTEM
The key benefit of the V3.2 bridle is that the kite maintains steering even when completely de-powered, increasing the usable wind range and overall performance significantly while adding immense safety benefits. The positioning of the bridle attachment points on the LE of the kite, combined with the V pulleys result in lighter steering, but direct enough to feel where your kite is while riding.
BAR PRESSURE ADJUSTMENT
All Airush bridled kites, excluding the Ultra and Session kites, feature the Bar Pressure Adjustments on the leading edge of the kite. These options allow the rider to select the perfect amount of feedback and comfort in the bar while riding with simple and quick adjustments before your session!
INTEGRATED HIGH MODULUS POLYETHYLENE YARNS
Central to the concept of the Load Frame are the lightweight Ultra High Modulus yarns, of which each single yarn can carry 40kg. Think of them as a lightweight web with engineered energy absorption under load, similar to a spider web.
These yarns are integrated into the canopy through reinforced taping that allows them to elongate when under extreme load, absorbing most of the shock that traditionally would have run through the canopy. At the same time, they carry the primary load of the canopy, preventing stretch and increasing long-term performance.
This premium fabric is designed with a high-density structure using high tenacity double-coated polyester yarn in a double ripstop configuration. The double coating protects the yarn as much as possible from UV and abrasion damage. This ensures that the canopy remains as crisp and responsive for as long as possible.
This exceptional material is used in conjunction with the Airush Load Frame, resulting in the ultimate combination of durability and performance.
XL INFLATE/DEFLATE VALVE
The XL inflate/deflate valve features an insanely easy and fast way to inflate and deflate your kite. The large opening creates maximum flow of air and reduces fatigue and stress on your pump. This in conjunction with the Airush high-velocity pump makes inflating your kite extremely fast to get you on the water as quickly as possible.
Kevlar, found in bulletproof vests, is found throughout the Airush kites. These Kevlar reinforcements are only put in the most critical areas to protect from wear and tear while still minimizing weight that affects the kites performance.
SPS & FBI
The oversized SPS valve (Single Point Inflation System) optimizes inflation and deflation. The Fast Bladder Inflation (FBI) features increased wall thickness and oversized diameter tubing, thus eliminating tube kink, reducing stress on your pump, and enabling quick and easy inflation. The SPS cover supports the tubing, further limiting UV damage to the material and preventing over flexing when packing.
I kite in San Diego where the wind is chronically light. Got the 14M of this kite. It performs admirably in these difficult light conditions. It flys and relaunches in conditions that would be impossible with heavier kites.
