Jonesey will probably kill me for posting this picture, but what the heck! He has been working on an automatic brake adjustment system for his handles. Following is a picture of the manual adjusters prototype - he wouldn't even let me take pictures of the auto system because he wants to market it and is worried it may be copied. He is going to develop the manual adjusters, having worked out the throw required from this prototype, into a proper trigger mechanism complete with a safety lock. For the auto system it has a spring loading that allows the top adjusters to give a little in the gusts, thus increasing the brakes when it is windy. It appears to be really difficult to get the spring tension right, but he has fitted some adjustable springs, and seems to be nearly there. The next stage will be to make the whole thing more robust and to stop the top lines catching in the springs when you do loose line work, and it should be ready for market.

Innnnnteresting!

Silly question, but is this to help launch the kite and then give it tons of brake?

Not silly at all. The idea is that in the lulls there is more forward drive. In the gusts it applies brakes progressively stopping the kite getting away from you with too much drive. So you are correct that it would allow an upright launch then apply more brake as the kite clears the low level slack winds.

Hi, might be a good idea to do some research - it sounds very similar to various methods used by sailors an aero modelers.

You might get some ideas from them :)

Why not just take a wrap of your leaders around your index fingers (not just at launch, but whenever you need more forward drive) and release from your index fingers when you don't need the drive but do need the brake?

(I don't see any difference between that technique and what's pictured as the manual adjustment)

Automatic brake adjustments would be neat, though I wonder if they'd still allow for something like a flic-flac.

Kite Killers are used most by Power Kites (Foil) these are attached to the bottom of the handles, and your wrists. If a kite gets to powerful or out of control you just let go of the handles, and the kite killers will slam on the brakes taking the kite to the ground.

Good theory with kite killers, and good in practice of course.

Unless you are stupid enough to go out in a "brisk breeze" with a 3.6 Waterfoil, dsigned to stay inflated when it lands in the waves.

Fly it in a muddy park, and when it pops open in the middle of the window and the handles are RIPPED out of your hands, you just get draged along on your face with a mostly inflated kite at the end of the lines.

Now who would be STUPID enough to do that.

Not saying anything else, except I am still trying to get the mud out of my coat!!
