Just out of curiosity, dose the stall happen you you have the bar fully in?

+1 ^^^^^^ what he said.

Before you launch the kite next time, get two mates. One of them wearing the harness and hooked in, and other helping him/her launch the kite, but keep them both there and tell them not to launch! Go over to the kite as it's been held and look carefully at the bridles. Are the ends of the bridles about the same distance apart and level in terms of distance from kite to bridle connecting point? I bet one of them (mostly likely the front lines) are too short.

Hi Stormbouy,

First of all, you have checked your bar and this is what you should do when a kite is not flying the way it should be.
Make sur that when you attached the end of the lines to an anchor point, all the line are under the same tension and the chicken loop is against the bar (or at least not more than 2/3 fingers away from the bar)

Next you might want to have a look at the kite, dont touch the bar anymore as you might use your bar for another kite.

There are few points that could explain the back stalling :
- Old bridles stretching
- Old canopy loosing tension and creating more drag.

Here are the step to do on a kite : DO THIS TEST IN NOT MORE THAN 15 KNOTS on a safe beach.
#1 - Check all the bridles and see if there is any damage.
#2 - Few kite companies give information on bridle length so check online for your kite.
#3 - Adjust the back line bridle by giving them more length. If there is no extra bridle on the kite, you can add a little pigtail. Start to add 5cm, then test, then 5cm more, then test ... until the kite is not back stalling. Then once you have find the right setting you can adjust more accurately 1cm by 1cm.

Go testing with someone as its quicker to land and launch and do the adjustment.

Good luck

Ben

Have a watch of this, should help a lot :)

... I can concur with Christan, lines will shrink rather than stretch.

I recently was doing some experimenting and I wanted to check what line lengths I had then noticed that I had differences between similar aged bars but one used more than the other. I then measured other bars with different use. As it turned out, the more the bar was used the shorter the lines got. I took a bunch of measurments but as an example, here is the lengths of just the front lines from the Y point to loops on North bars noting down the age/use.

12.65m over one year old bar, well used bar heavy rider
12.70m over one year old bar, not as used bar, lighter rider
12.80m 6 month old bar, not used much bar, light rider
12.90m new bar never used.

I would imagine that not only does the bar lines shrink but I bet the bridles do the same as well.

When checking lines and re-trimming, give each one a good tug then do your adjustments but don't be surprized if you have to do it again soon after a few sessions.

cheers,

Robbie

the variation in front vs back lines I have seen can be more than 10cm you can't put this down to different rates of shrinking can you? Front lines stretch because they are under load all the time.

That's what I used to think and what just about everyone thinks as well. I thought the whole line shrinking theory was a load of BS, until I started measuring lines. Over and over again I come to the same conclusion: lines shrink. But don't take my word for it, measure old lines vs new lines like Puetz and I have done, you will come to the same conclusions!
