Features
Cord Cut Billow
The CCB Cut is an advanced design feature aimed at optimizing airflow along the leading edge of our Foil Kites. Through strategically placed, precise “billows” – targeted cuts along the chord line – the profile is modified to ensure smoother and more stable airflow. This reduces turbulence, compensates for surface irregularities, and minimizes drag. It optimizes sail curvature for maximum profile fidelity and enhances aerodynamic efficiency. The result: higher stability, better power delivery, and more precise control under high loads.
Aero-Balance Construction
The Aero-Balance construction combines a high aspect ratio with a finely tuned cell architecture, ensuring maximum performance while maintaining intuitive control. The profile fills quickly and evenly across the entire span – particularly important for launches in strong winds or challenging conditions. Increased user-friendliness, faster response to steering inputs, simplified handling during jumps and loops.
Air intake line
Lines have been stretched spanwise across all air inlets to ensure optimal airflow to the leading edge. The air inlet lines hold the rigid foils on the nose in position and prevent the inlets from deforming. The kite fills quickly with air. You get control over the entire wingspan sooner when launching the Foil Kite. The kite also flies further to the edge of the wind window when overpowered; the leading edge dents later, and the depower works more efficiently.
FlowArc Wingtip
The FlowArc Wingtip optimizes airflow over the wing tips and improves flight behavior in loops and during recovery. Through its curved shape and targeted profiling, it generates additional lift, delays flow separation, and enables particularly smooth and precise control. Every loop becomes more controlled, intuitive, and safer. Whether landing or downlooping – the FlowArc Wingtip supports the SONIC characteristics: powerful yet predictable.
What All This Means!
Improved Heliloop performance
The redesigned wingtips create smoother, rounder loops that catch you gently and slow your descent. Perfect for controlled landings and safe progression during high-risk Heliloop maneuvers.
More jumps per session
Efficient upwind performance, low drag, and responsive handling help you return to your take-off point faster. That means more airtime, more attempts, and faster trick progression in every session.
Easier landings
Refined steering geometry improves how the kite catches you after tricks. It softens impacts, enhances stability, and gives you confidence to land cleanly – even after technical rotations or loops.
Extended hangtime
The SONIC⁵’s high-lift profile delivers maximum hangtime. Stay in the air longer, gain valuable seconds for your tricks, and enjoy softer, more controlled landings with every jump.
