The success story continues!
Our ultra-lightweight high-performance gliders regularly set the tone at hike & fly competitions. With the XALPS3, we wrote aviation sports history in 2017: four of the five best-ranked Red Bull X-Alps athletes flew our gliders – including the winner.
The X-ALPS4 is a complete redesign – developed with the technological know-how of our R&D team and the intense experience of our X-Alps athletes. All it has in common with its predecessor are its 6.99 aspect ratio and certification for EN/LTF D. Dimensionally stable Rigid Foils and a highly complex internal design enable an extremely stable wing with extremely high pitch stability for on-bar gliding, and maximum resistance to collapses at high speeds and in turbulent thermals.
We deliberately chose a 3-line concept for the X-ALPS4, which, in our view, is currently the best symbiosis of high performance, low weight and ease of use. Thus, the new X-ALPS4 is not only a tool for the athletes of the 2019 Red Bull-X-Alps on their more than 1000-kilometer long route from Salzburg to Monaco, but also for all XC pilots looking for a performant and extremely well-balanced racing wing.

HOW DOES THE X-ALPS4 FLY?
The X-ALPS4 is a high-performance glider with a high fun factor. Its dynamically playful handling seduces you to exploit the full potential of the day, no matter how difficult the conditions.
The ease of use starts at launch. The clear line setup and the redesigned Dyneema risers make it even easier to prepare for launch compared to its predecessor. Even with a slight tailwind, the canopy of the X-ALPS4 kites evenly and remains stable. That makes launching in challenging terrain even easier.
In the air, the X-ALPS4 will impress you with its pronounced pitch stability. Its performance is easy to access and the glider is amazingly stress-free to fly. When flying on-bar, you can correct nick movements with the advanced Speed Control extremely efficiently, and control in turbulent air at high speeds requires less effort. In thermals, the wing gives you excellent feedback via the brakes. Control pressure is lower and brake line travel is longer compared to its predecessor, which significantly increases flying comfort.
The technical data with a 6.99 aspect ratio and 82 cells guarantee a real race feeling. Combined with its stable flight characteristics and low weight, the X-ALPS4 is the first choice for all hike & fly competition pilots as well as for uncompromising XC hunters!
3 LINE LEVELS
The 3-line-level concept reduces the number of lines and the resulting drag. Advantages: more performance and a better overview at launch.
The Rigid Foil nylon wires on the leading edge help maintain its shape and ensure constant ram air pressure. Advantages: better takeoff behavior, more performance and lower canopy weight.
Doubling the number of cells at the trailing edge increases its shape stability substantially. Advantage: fewer vortices improve the aerodynamics and with it the performance.
C-wires are nylon wires sewn into the glider over the anchor points of the C-level lines. Advantages: better load distribution, reduced drag, more performance.
A precise calculation of the leading edge geometry and the installation of an additional strip of fabric reduce wrinkling in this sensitive part of the glider. Advantages: exact wing shape, more performance.
Handle on rear riser which allows the pilot to even out turbulence, speed and pitch while flying on speed bar without having to release the speed bar.
Together with a corresponding wing design, the shark nose technology improves pressure distribution in the canopy substantially. Advantages: much more solid flying feeling and substantial performance gain, especially when gliding on bar.

Is the deterioration on light-cloths higher than on a regular glider cloth?
Light-cloths are thinner than conventional glider-cloths and therefore less resistant against mechanical strain. That means you need to pay more attention on small rocks and bushes. Please avoid any unnecessary contact to the ground. With this strict observance you will have the same durability as with a conventional glider-cloth.
What are the glide ratio (L/D), trim and maximum speeds?
We know that these data are interesting for you as a pilot, but for us to publish them would be a bad idea for the following reasons:
1) Performance data are highly dependent on the drag of the pilot and are therefore related to sitting position and harness. The difference between aerodynamically favorable and unfavorable harnesses and sitting positions can be as much as a whole L/D number.
2) Performance increases with the size of the glider. A large glider will always outperform the same glider in a smaller size. So a question about the performance of a glider is always also a question about the size.
3) There is no normed method of testing the performance of paragliders. For example, speed varies with altitude and the associated different air pressure, but also with the total weight of the system.
That means that there simply isn’t THE speed or THE L/D that would allow a serious comparison with another glider. Performance data are dependent on the harness, the size of the glider, on the air mass and the total weight.
How do I calculate my takeoff weight?
Takeoff weight is calculated by adding the weight of the pilot including clothes to the weight of the equipment. The equipment consists of the harness, the reserve chute, the paraglider itself, and any flight instruments and other baggage you may carry (e.g. rucksack, etc.).
Is it OK for me to shorten the brake lines on my skywalk paraglider?
Changing the length of the brake lines can have a negative effect on the flying characteristics and extreme flight behavior. The paraglider needs a little more lead when flying on speed bar, otherwise the glider could be braked unintentionally, leading to a loss of performance. When performig extreme flying maneuvers, shortening the brake lines too much can cause complications during recovery from collapses, parachutal stall, etc.
Am I allowed to make modifciations to my skywalk paraglider?
No, because the glider is certified the way it is delivered to you. Even the brake line length is part of the trim and must not be changed.
Do the nylon wires in the glider need any special attention or packing method?
Yes, we recommend to use the softbag light and the packing tubes for packing your glider. You can find the exact packing instruction in the PRO GUIDE.
