The reserve system is an essential part of our flying gear and we all fly in a way not to use it. However, if anything goes wrong, the deployment must be fast, opening quick and descend stable and sink rate very low. Sky Paragliders reserve QUATRO was developed from scratch during the last five years to meet all the demands. Just read the story about how QUATRO was born.
When we started to examine the square reserve concept, we wanted to understand every single detail to produce an exclusive product. We did not want to have "one more square reserve" on the market, but to bring unique, fully functional and in a way, easy to use (no matter how much we all wish not to use it all) reserve.
Therefore, we did not start the development in a common way; we did not design several prototypes to find the one that matches the EN criteria best.
We wanted to understand more about the concept - the way the load and shock distribute into the canopy; the factors that play the most vital role in the stability. The complex study of materials available on the market and their influence on sink and stability helped us to combine the shapes, materials and the design techniques to come with the most complex solution. All that resulted in QUATRO, a unique Sky Paragliders reserve that is a safe, stable and reliable square reserve and ready to help in everyday flying, during competition or bivouac expedition flights.
What do pilots like about QUATRO?
The main distinctive features are:
Each QUATRO is delivered with:
|Surface area (m2)||22.5||27.5||32.5|
|Max. payload (kg)*||90||110||135|
|Min. payload (kg)*||60||73||87|
|Sink rate at max. payload (m/s)||4.9||5.25||5.4|
|Weight of the reserve (kg)||1.2||1.4||1.7|
|Certification||EN 12491 / LTF||EN 12491 / LTF||EN 12491 / LTF|
* weight of fully-equipped pilot without the paraglider
If you would like to design a unique product, you have to start in a very complex way. So, the journey to QUATRO was a mission to understand many challenges. How is the load distributed? Can we use traditional loops for lines and still pass the load test? How about the material? What is the load for warp and weft? Which manufacturers bring the best material: How about the lines? They should be stable and still able to compensate for the shock if the pilot deploys the reserve. So many questions and many challenges to solve if you want to work on your own.All the chores were compensated by QUATRO which is the lightest reserve with the traditional (9082 series) material on the market. So, get one and fly in a way not to try it :-).
