Competition in fun class, Hike & fly and XC, intermediate, fun flights
The CROSSROCK is a hybrid of lightweight and everyday-glider, that offers high comfort even on extensive routes. It is hungry for far destinations and pulls towards the cloud base even in weak thermal conditions. Thereby the smooth glider slices through turbulent airmass and is hardly knocked off course.
Despite its low canopy weight, the CROSSROCK lies heavy in the air and light in hand. Control pulses are translated accordingly precisely and the wing is easily rotated into the thermal lift. The performance-oriented lightweight glider is aimed at pilots who desire light luggage and small pack size for everyday flights on the XC route. Whether it is flying in the reliable thermal spots, travelling to remote places or on the mountain, the CROSSROCK is built for the trying use in everyday life. The mid-B wing offers maximum safety reserves through damped reactions besides its outstanding rise features. Finally, the good feeling is what ensures the lasting comfort on long routes. At the high-performance capability and the sweet-tempered features, the constructional proximity to the BLACKLIGHT 2 is clearly discernible.

Chief designer Ernst Strobl counts on the efficiency of simplification at the CROSSROCK. That does not only lead to a weight reduction but also gives the wing its outstanding characteristics. Based on the concept for the success of the Blacklight 2 several modifications for the CROSSROCK were made to maintain the form fidelity at long durability. The shark nose provides more stability at higher speeds. The 3D-shaping gives the leading edge a dynamic tension and elevates - in combination with the Precision Profile Nose (PPN) - the profile fidelity in the nose area. Pre-tensioning of the wing and the ballooning help to provide the perfect flow around the profile through
elaborate calculations. The High-Pressure Crossport Design (HPCD) optimizes the lateral aeration of the crossports and provides a balanced internal pressure of the wing. The line-set-up with three main lines is very straightforward. Here the newest generation of PPSLS lines are being used, which ensure extremely high loads with minimal diameter.
The material mix combines optimized weight management with maximum durability. The small weight of the canopy retains less energy and therefore facilitates the sweet-tempered reaction behavior of the wing. Only the premium lightweight materials Skytex32 and Skytex27 were used in the glider, these clothes have double coating and help - because of the small weight - the everyday long-term durability.
