    ERIS 4 is the latest generation SKY competition glider. But, as one might guess, even this glider is aimed mostly at novice competition pilots who are new to high performance wings and competition flying and would appreciate both the stability and performance to take on new flying challenges in the comp circuit.

    The main distinctive features are:

    • stability
    • high efficiency in thermals
    • distinctive SKY handling
    • speed when the speed system is deployed
    • one of the lightest wings on the market
    • state of the art manufacturing and high quality

    The main changes compared to the third generation of the glider are:

    • new geometry and the setting of the wing for further performance and stability at higher speed
    • the aspect ratio increased to 7
    • only 3 sets of lines
    • overall improvement of gliding ratio, increase in the trim speed and maximum speed

    Each glider is delivered with:

    • porter bag
    • T-shirt SKY TEAM

    Canopy

    The canopy is made out of the material DOKDO produced by the South Korean textile factory Dominico Textiles. To reach the high quality and increase the durability of the canopy, we combine several materials and coatings. The upper panel are made of DOKDO-N20 DMF (WR), 36 grams per square meter.Profiles are made of DOKDO-N30 DFM and the panels for the leading edge are made of DOKDO-N20 DMF (WR), 38 grams per square meter.

    The material is made of Nylon 6.6 fibres (PA fibres) produced by Du Pont. The weaving pattern is the so called RipStop structure.

    Line scheme

    The lines on the ERIS 4 are of the highest quality and are supplied by the firm EDELRID and COUSIN TRESTEC. These lines create high resistance from mechanical abrasion as well as a high degree of length stability.

    For the upper cascade we used ELDERID 7000-060 lines. These uncovered kevlar lines are 0,6 millimetre in diameter. The lower lines are manufactured out of Vectraline (Cousin Trestec) and the main brake lines are made from EDELRID 7850–200.

    Risers

    The risers are made from 13 mm wide webbing manufactured by our supplier MOUKA TIŠNOV. The suspension lines are connected to the risers by means of quick links (mallons) from the French supplier MAILLON RAPIDE (PEGUET).
