Light

Light kites always fly better than heavy kites. In principle, this is nothing new and is widely known. For a long time not much attention was really paid to this as the kites were instead unnecessarily overdesigned to achieve the highest possible quality look. The Nerio II also follows its own goal and should cover my range of use perfectly which is mainly in light winds with the twintip or with the hydrofoil. First and foremost the kite has to be particularly light. For use on the twintip and jumps in the lower wind range, on the other hand it still has to be stable. Thanks to new materials and a modified profile, the Nerio II is now able to cover both ranges of use perfectly and also perform very well in the upper wind range where light kites are simply more fun.

Efficient

The special efficiency of the Nerio II is the high performance for use on the hydrofoil, as well as the twintip and the particularly large wind range. I don't want to keep going back to the shore and inflating kites just because the wind has just picked up or dropped. On the foil you are quickly overpowered and with the twintip you also appreciate a kite with great depower and sovereign flight behavior. On the other hand the lowest wind range requires a powerful kite to generate the necessary pull on the bar so that the jumps don't turn into hops. But it's not just the pure wind range that is important to me. My kite must also have a linear pressure build-up and be totally easy to relaunch even with very little wind. I also want to kite a high aspect ratio kite like the Nerio II with the same 52cm bar as the Maverick III.

Agile

Even a kite that has a lot of power in the lower wind range must not be sluggish. For me it was therefore very important for such a high aspect ratio kite to be extremely agile, but doesn't flap and doesn't move too much on its own. Thanks to new materials, the Nerio II is much more compact in flight especially in the upper wind range.

I don't want my kite to limit my riding style which could happen with a lame and sluggish kite. In my opinion an agile kite is also a clear advantage when hydrofoiling as I can react so much faster, because when foiling you often have very little tension on the lines and a sluggish kite is only a hindrance. The Nerio II has therefore been developed with this characteristic in mind from the very first prototype in terms of shape, construction and bridle system.

FEATURES

"The primary goal in developing the Nerio II was to maintain the impressive low end performance but give the kite better control in the upper wind range."

New LE-Material

A lot has happened in the materials sector in recent years. Aluula laminate in particular has opened up completely new possibilities in kite design. However the sensitivity of this material has always bothered me which is why I have never wanted to use it for my kites. I wanted a material for the front tube and struts that was not only just as light as Aluula, but also had the same incredibly good strength values, but was also much easier to pack and more durable. The development of stretched PE fibers was just what I needed. The cloths with this HDPE fiber have almost the same technical values as Aluula and are even superior in some areas. The combination with the black, laminated Technora threads results in an extremely tensile material which now gives my kites a completely new riding experience. This makes the kite much more controllable and therefore even more powerful especially in the very upper wind range. Previously my kites had a Dacron cloth for the front tube and struts with around 145 gr/m2. The new cloth is only 85 gr/m2, but is much more stable.

New Canopy

Due to the enormous weight saving in the material for the front tube and struts, I was able to use a new canopy material for the Nerio II which is slightly heavier than the cloth previously used. I deliberately opted for this heavier cloth because the kite is not heavier overall than before, but its flight behavior is even more direct. In comparison the new cloth now weighs only 9 gr per m2 more. However this "small" difference makes a big difference in the tensile strength and also in the durability of the kite. The previous cloth in combination with the new HDPE material for the front tube and struts would actually have made the Nerio II a good deal lighter, but the test rides with the previous cloth and the new canopy material have made a clear decision. All my test riders and myself found the prototypes with the new canopy material much more direct and powerful. Especially in the upper wind range the Nerio II now behaves like a high-performance wing and is therefore particularly recommended for use on the twintip. Many kiters switch from foil to twintip when the wind suddenly picks up without wanting to change kite.

Profile

Every kite needs a powerful profile and a stabilizer at the wing tips. This stabilizes the kite and this position determines how the kite behaves in very tight turns and at the very edge of the wind window. With the Nerio II I have intensively revised the entire profile. The highest point in the profile is now positioned a little further back. I have also made the profile significantly flatter especially towards the wing tips. These changes make the kite feel more neutral on the bar without losing its good forward performance. The kite has a good mix of performance, bar feel and easy relaunch behavior. You always know where the kite is in the wind window even without looking. This is a very important aspect for use on the hydrofoil especially in the lowest wind range.

Struts 1plus2

My kites should always be light even very light. No-Strutter are very light, but mostly have a small wind range. They work very well at low winds, but as soon as the wind picks up you have to change kites because the handling then becomes disastrous. Single-Strutter can do that better, but even then I missed the support of the profile at the wingtip when forcing the kite into very tight turns. On the other hand developing a classic three-strutter would have taken me away from the goal of developing a very light kite with the Nerio. That's why I've modified the two struts near the wingtip to micro-struts with extremely thin diameters and call this 1 plus 2. This design is almost as light as a single-strutter, but the kite turns way better and in the high end wind range it has more control, because the profile is better stabilized. The concept works just as effectively on the Nerio as it does on the Maverick.

Twist

The way birds fly has always fascinated me, especially their maneuverability. They achieve this by completely twisting their wings. No bird has rigid wings like an airplane. Every airplane designer would dream of being able to realize a stable and easy wing twist instead of being limited to flaps at the wing tip. A kite with a front tube that is too stiff is almost like a rigid wing. Such a kite cannot really be influenced in its flight and turning performance by the kiter as the steering commands are usually only applied to the wingtip. The Nerio on the other hand can twist or twist as a whole because it has a very thin front tube. It therefore turns much tighter and, more importantly, the air flow is permanently present on the kite due to the wing twist. You notice this immediately because the pull on the bar remains constant even in really tight turns. For me this is an indispensable feature both with the twintip and on the foil. Thanks to the new HDPE material on the front tube and the struts, I can now control the twist characteristics of the kite even more precisely depending on the pressure with which I inflate the kite. The more air pressure in the kite the stiffer the wing.

SUP-Valve

After many tests I decided on a SUP valve for the Nerio II. This makes it possible to read the exact pressure on the pump pressure gauge even if you are not performing a stroke on the pump. The air flow in and out is greater which makes the pumping process and deflating easier and quicker.

Construction

The requirement to build a lightweight kite for use on the foil which is also stable enough for use at high jumps on a twintip demanded a new rethink in the design. Thanks to new developments in the materials sector I was able to make the Nerio II even more robust than ever before without losing its lightness. This has given the kite another noticeable performance boost. But even with the Nerio II I have only used reinforcements where they are really necessary. The HDPE material is a little transparent so you can easily see the construction inside the kite. All seams on the LE and struts are doubled and reinforced with special tapes.

I have further intensified the successful cooperation with the repair workshops in the design of the entire construction, because only from there comes a reliable experience which construction details really make a kite more robust in real practice and what only brings a nice look.

Kite-Bag

A light kite needs a light kite bag. That's why I chose the same bag for the Nerio as for the Maverick. With only 135 gr this bag is really light and fits well for traveling. It is simple, functional and nevertheless solid. No needless details and just the focus on the essentials. A bag how I have always wanted to have. The two side lines close the opening at the top of the bag and also serve as a shoulder strap. Because the Nerio kite and the bag are so light no padding is needed here.

DNA

"The new HDPE material is a significant improvement. However this material is also much more expensive and more complex to process which results in a price increase. In relation to the DNA of Kauper-XT our kites are still fairly priced and for me the decision to use HDPE was definitely the right one as it clearly brings more performance to the kite."
