Our STABLE 2.1 RACE RAST sets new standards again in all flight areas of a hybrid paraglider. Above all, the good start-up and sliding properties when flying quickly or slowly reveals the entire level of performance. It can be flown very sporty, but he also likes very slow cruises - always with a high security reserve.

The good steering properties and high maneuverability were also very important to us. This can also be used to boost weaker and very tight thermals.

Briefly about the history of development:
RAST® paragliders from Swing always fascinated me during my man-carrying time.
Herry Hoffner, an RC paraglider pioneer from the very beginning, began gaining the first experience with RC paragliders in self-construction a few years ago. His construction, the "Olympic", made us available with his findings. This umbrella had no RAST® valves, but served as the foundation of our development of the STABLE. In the first step, however, it was necessary to get in touch with the company Swing in order to be able to integrate the RAST® system they patented exclusively into our RC sports gliders.
With the contractual approval of the use of RAST® and the "Olympic" as the basis, we started our exciting further development of Hybrid-RAST® RC sports paragliders with high extension and small number of single skin cells.

The aim was to develop a hybrid glider that is always good-natured and easy to fly when starting and in a variety of flight phases, which is already "marching" in the normal flight phase and does not collapse very strongly when accelerating . In the thermal position, too, it should have good and stable handling in the area of the slightest sinking. In any case, we also wanted to keep the number of open, i.e. single-skin cells, as low as possible to get maximum sliding power.

In order to meet these requirements, it was necessary to carry out countless iterations of flow simulations of the cap. The result is a profile strac with 4 to 6 different profiles in the direction of a range depending on the glider.
A perfectly tense profile nose, which also simplifies starting, we achieve through the use of Nitinol, a shaped nickel titan alloy with a memory effect. This was a big challenge because we have very thin profiles with tight nasal radii. The classic bag for nylon sticks cannot be taken over one to one for this.
The latest generation of Edelrid Magix Pro Dry is used as cords for our gliders.

The heart of the RAST® gliders, the RAST® valve, brings a lot of advantages in flight, but represents a lot of effort during the development phase and in prototype construction. A larger number of prototypes in comparison to conventional shields is needed. This is because the overall construction and the voltage distribution are mainly related to the RAST® valve. A lot can be changed on a conventional prototype without RAST®. If something is wrong with the RAST®, it cannot be intervened because it is installed inside the cell and a completely new prototype must be built.

Ultimately, only the ellipes shape remained from the Olympic. We calculated new profiles and created a modern profile strak in flow simulation, integrated rest valves, adapted the RAST to have a better effect. Above all, we changed the wing tension. The sticks were all constructed on the modern Nitinol system, a nickel titan alloy with form memory. The interior was constructed on lightweight construction. In many test series, we flew the optimal linen lengths and angle of attack of the different sections.

Well, dear customers, we have reached the destination with the Stable Race and can offer it to our customers.
