Shoot the breeze and stay in the loop with the unhinged and unhooked word on the street.

We pump our kites till we can pump no more. Or sometimes we use the electric pump, which is set to 8.5psi

no the reason i ask is some one mentioned they pump their kite to the max 9bar..

I personaly know no other person ( now one from a phone call I asked them typical )

Pumps their kite to the max!

I always am just under as I use a North Pump which has black yellow and red and I only take it to the safe amount.

Which is under the max.. reason i ask is I wouldn't want it to the max incase you hit the water and it bursts! Some riders I help send their kites up who I know are really really good I noticed anumber of their kites to be alot softer!

Just seeing what other people are doing...

From what I understand and personal experience the harder you pump the kite the better it perform (ie not deform its shape). However there is a trade off in that if you have a very high PSI and you crash it then you are more likely to blow out the leading edge. If I am not going to crash it then I go to 8/9. If I am trying something that might involve a few wipeouts then 6 PSi (I also leave the valves open on the octopus system to help absorb the impact).

Ah, the 'joys' of selling to some people

You can not please everyone all of the time, no matter what and with some, you can not reason with unreasonable people

Unfortunately it's something a lot of us have to endure' when we sell kites :x

Pump to the max in terms of tiredness and 'pingyness' of the LE. Use the guage as more a verification of your efforts.

TBH, I can't see how it's possible to over-inflate using a standard kite pump anyway as they tend to become too difficult to pump just at the point the LE is ping/drum tight (except when it's really hot weather maybe - but even then it's not you over-inflating the kite, just the heat causing it to expand).

If you've got a newish kite pump it up till it's rock hard, the chances of blowing it out are small and performance and relaunch are improved. I was told to leave the one pump system open the other day. I spent all weekend splashing my kite into the water without any issue.

every ones an expert.. I am so upset by this...... I sold it for alot less money than others! I even emailed the other sellers to say sorry I am selling mine cheaper! I only sold it cheaper because my new one was cheaper and I thought I could help some one up the ladder!

one person I asked just came out with it.. there's always some one that wants more!!!!! and said little knowledge is dangerous. Now that summed it up!

Someone also said that to me, on the grounds that with the one pump system open there is more volume to absorb the impact of any major slamming of the kite. I pointed out that only a few weeks earlier I had done a self-rescue when my LE bladder went down (a valve seal gave way) and if I hadn't closed off the strut clips I would have been in a more precarious situation. The struts definetly gave me enough structure and support to self-rescue. I have never tried a self-rescue with a completly deflated kite in deep water, large swells and a few hundred meters out and tbh I don't fancy trying it. So my advice would be that one should consider shutting off at least a couple of the struts. Perhaps a learner who is close to shore and crashing the kite a lot might be an exception but I would still say get in to good habits early. A burst bladder is a pita for sure but not worth the safety trade off in my humble opinion.

From an industry perspective;
9 is too much, though I have used it on unstable kites before.. (pure bows in the early days)
As a rough guide, the pressure helps the kite keep it's structural frame, and so the more you put in the more structurally stiff it is. This is good for all riders, but it does increase the chance of failure when you stack it hard.

So lower pressure is often preferred, as long as you can get away with it structurally....

but,

The problems come when you have structural issues (tips flicking, leading edge deforming under de-power), which are worst when;
- you are very heavy and use kites on high levels of de-power in huge winds
- you use kites that are very efficient and sit a long way forward in the window, again on high levels of de-power
To get round the above you have to pump them hard, and try not to nail them in the deck if you can help it :-)

Airush say 7psi as a rule.

Also gauges lie - they are not all calibrated.. Pump till the pump gets stiff for 7-8 psi. And check with your mate's gauge if you are concerned..
The first thing I do if someone comments about structural stability is I send them a new gauge and tell them 7psi, then bingo; instant cure...

and if you want to make your kites last longer NEVER let them flap on the beach, always put as much sand on them so they are pinned front and back. Any flogging means you are ticking it's life away at an alarming rate, and that goes for the Tejin's too (widely considered to be the best and certainly most expensive materials out there)..

Totally , the chances of blowing the LE on a newish kite from slamming it is next to none , anyone who ever tells you to leave the struts unclipped thou , has never had to swim in with a sunken kite or drag the bugger tru a mile of waist deep water , with the bladder full of water.

Tbh its very rare for anyone to slam a kite into the drink harder than a beginner , hanging onto the bar of a kite screaming toward the water.
I always make my student pump their kites till the pump wont pump anymore , so about 10psi. And have yet to see a bladder go pop on a newer kite , i see alot of dump values open thou as this is always going to be the weakest point on the bladder , we take a small pump in a backpack onto the water on busy weekends because it happens regularly enough to be a pain.
People will get alsorts of outlandish ideas about what they "think" is a good thing to do , but quite simply the flight characteristics and relaunch properties of the governed by the structure of the canopy , which is provided by the firmness of the struts and LE . If the thing was supposed to bend and sag the designers would make it that way.
