The Flat Winglet technology reduces the induced aerodynamic drag, but at the same time increases lift. This leads to a noticeable improvement in lift to glide ratio and forward flying speed of the kite. As well as better turning speed without wingtip collaps.

Thanks to a new ultra high-strength Dyneema SK99 fiber core, we developed in cooperation with LIROS new, significantly thinner race lines. The front lines have only 1.45mm thickness and 300kg breaking load, the back lines an amazing 0.8mm thickness and 160kg breaking load. The completely unsleeved Dyneema bridle is correspondingly even thinner.

Thanks to Double Cordwise Ballooning and Rigid Foil Technology we have found a technical solution that eliminates the slight weight penalty and wrinkling of the Deluxe cloth. Different fabrics are used for internal ribs, v-cells and straps since airtightness is less significant here, but diagonal stiffness is important. The SONIC-FR top and bottom sail fabric are deluxe cloth, which has no disadvantage in performance and pricing is not increased unnecessarily.

The proven drainage system integrated in the whole trailing edge of the kite, with finally openings near the tips, about the size of a hand. They allow water and sand to be drained automatically, without influencing the performance of the kite.

FLYSURFER is passionate about kite-racing and has registered the SONIC-FR kite officially. This allows you to attend every official IKA racing event. Even if a FLYSURFER kite construction is officially approved for kite racing in the IKA class – Formula Kite, this does NOT mean that the kite itself is automatically IKA registered. This must be registered by the rider him/herself, so that he/she is allowed to officially compete in the IKA class – Formula Kite and it’s specific events. Link to registration form
