I've got a 07 Flow 10m with three knots on the kite attachment for the steering lines. I think the kite turns faster and the bar pressure is heavier as I move nearer to the kite.
Could someone confirm this / explain how they work?
The top knot, closest to the kite shortens the back lines. This 'powers up' the kite. The bottom knot 'depowers' the kite by adding length to the back lines.
