You will need a C kite with multiple steering line attachment points by the looks of it...

"In the process of improving Windwing's Dynamic Structural Influence (DSI), we came across a simple modification that can improve the turning speed of any kite. This modification will be an available accessory for Windwing kites but for those existing owners who would like to inprove the turning performance of any kite, here's a simple Windwing tip."

That looks like another spot where something can go wrong.
Pullies in the sand...we all know how well they wear out lines that are rarely checked.

What happens if you crash and the extra loop hooks up and over the back, It will rip your trailing edge or the kite will turn off in one direction once launched.

Thanks for the tip but K.I.S.S.

So this is on the trailing edge. IE: steering lines.

The way I see it when you sheet out the pulley will move towards the front and visa versa.
while in use it will hover inbetween and relatively close to the centre attachment point of effort.
I would like some feedback on an objective comparison of this setup and just using the centre attachment.
I am looking for an improvement that justifies njpornstars valid concerns.
We Airblast Bred Kiters know of pulleys, and also a whole new generation of kiters are discovering the fun of pulleys.
