Does that mean you have been made into a tart...for the second time?

A.


Haha hahaha that made my morning.

Thanks.

The answer is ping test buddy.

Flick the LE like your flicking an ant off a table or perhaps flicking a buddy in the ear. Once it goes from "thud" to "ping" your ready.
If it goes from "ping" to "pop" or "bang" then you have pumped to hard. Back in back to "ping"

Never trust those plastic gauges that come with our pumps...

Digging up this old thread again. Does anyone know how many liters of air a typical 15m kite holds? I'm thinking of buying a compressor for a nail gun for a home building project. If I can use it to fill my kite, it would tip the scale.

I want to plug it in before I leave the house to fill the reservoir of 24 l at 8 bar. Then drive to the beach and fill the kite :)

standard dual action is 2 liters per stroke, so 4 liters per full pump, if a 15m inflates with about 50 strokes that's 200 liters at 1 bar <--- on a brand new pump, my pump is only delivering about 1 liter per stroke right now.

24 liters at 8 bar is 192 liters. so it will not top off a 15 meter kite. Also you can't get all the air out of a tank, since a kite inflates to .55 more than standard pressure, so actually it would be 8-.55 = 7.45 * 24 only 179 liters worth of air at 1 bar before the tank and kite equalize in pressure.

So you would need to pump it 6 times by hand.

Thank you, edt.

I'm thinking of starting off by inflating the kite through the deflate valve, with the nozzle of the air gun just at the opening. I think the air flowing in will pull more air in with it. It is some kind of physics effect :)

I think you were right the first time, as one bar of the air inside tank can't escape, as the air flows out of the tank because it has more pressure than the outside. The outside is 1 bar.

Atmospheric pressure (1 bar) is about 15psi.

So, if you count the number of pump strokes it takes to fill but not pressurize the bladders, and then pump half that many times again, your bladders will be pressurized to about 7.5psi (over atmospheric pressure).

Why can't they make kites like that? Somebody should get right on it. :thumb:



They did. it's called Flysurfer Peak... watch the videos in Kiteforum
