Pumping hard or not

Postby kootsie » Sat May 17, 2003 12:23 am

What are the (dis)advantages of pumping up the kite softer does it influence your flying performance?

The softer it is the harder it is to water relaunch, it also is more prone to flapping in gusts. however the harder it is the easier it is to burst if it comes down hard.

Just how hard should you pump your leading edge?

I inflate mine so that I hear the "ping" when tapped with my finger. However, when walking on the beach holding the kite in the middle and walking against the wind the kite slightly folds in the middle. Is this still too soft?

I pump my kite up "fake titty hard"
ya'no firm but not rock hard
consider too the amount of air expansion that'll occur due to increased temperature
i've seen the LE of a kite sittin on the beach explode and scare the hell outta bunch of folks
blew up cause it was overinflated early in the morning but at the roast of noon KA BOOM

mine is always pumped up very hard as well, so it doesn't yellyfish and has a very stiff profile so no power gets lost.

I dont like mine rock hard !

As long as they are not too soft, relaunching (rolling over) seems even better, and I like kites that work a bit in the air.

Besides the fact that your kites will last so much longer, and not wear out.

So I dont like rock stiff kites (but most others do I think...).

The heavier you are, the harder the kite has to be pumped though (I am 73kg only).

i like mine just soft enough to get a kink in it when i self launch it, but absolutely no softer, pumped up it should ping rather than drum when flicked.

A good way to have consistent LE pressure is counting. How many strokes you have to pump after wing tips gets up, to get the right pressure? (Perhaps you could write down this number over a tape just at the side of the valve, or at your pump).

Small kites needs less overall pressure. Big & long LEs needs a little more to stay firm.

A softer leading edge will flip over easier on to its back. The kite has to break in the middle to roll over otherwise it must lift up the tips.
You could pump it softer for underpowered conditions and harder for overpowered conditions.
Relaunching in strong wind will be easier so it does not need to be soft.
