Any tips for pumping up small kites?

Postby sflinux » Thu Jan 10, 2008 5:31 pm

The smallest kite I ever owned was a 2-line 3M CO2.
My smallest now is a 5M Type 7.
Both of these kites have small bladders. I find it hard to pump them up, plug up the nozzle, and still have any decent air pressure inside the struts.
I flew the 5M the other day and it would get a crazy wobble when it starting flying really fast. I assume it is because it didn't have enough pressure in the tipward struts.
Any tips?
One thought I had was attaching fiberglass spars on the outside of the tipward struts to help stiffen them up.
thanks.

Strange that they don't have one-way valves on the bladders... that's the key.

I had a small kite many years back that didn't come with them, so I swapped the bladders on the smallest struts with ones that had one-way valves. and it did the trick.

I was having the same problem a while back with a kite. I had some success with stuffing the pump tip in tight, pumping the batten almost as tight as I needed to. Then I would pull the tip out slightly and pump until the pump tip blew out of the bladder. This would usually seat the stopper ball. Good luck.

If it has a stopper ball in the bladder, just hold it upside down when filling and removing the pump nozzle. Gravity will seat the stopper ball, and you wont lose any air.

you need strong fingers and thumbs!

Pump it up as hard as possible, then use your thumb & forefinger and squeeze like your life depended on it, take the pump out and stopper in

if you are still struggling, wrap gaffer tape round the jaws of a pair of long nose pliers (to prevent damage to the valve) and use them to squeeze it

Most newer kites have very efficient contra vents :thumb:

If older models with stopperballs - remember to hold the valve/strup upside down, so the ball will drop and stop "faster".
Often helps on these older types 8)

After pumping up tight. Don't pull tip straight out. Quickly flick the tip out in a horizontal motion. This will set the ball in place instantly with no air loss.
Make sure you pump it up tight first.
