Going travelling and want to fold my kite to same package as when originally taken out of the bag. Any instructions or how to out there?
Kites are North Rebel 2012.
you cant really achieve that folding due to the fact some air will always remain inside. You can get close though. I find the best folding for traveling to be that 1 only a bit more planed
volume = temperature (k)/pressure
there's nothing magic about the pressures in cargo holds. a 90% deflated kite may increase its volume a tiny bit as the pressure drops slightly more than the temperature, but unless you pack your kite fully inflated you have nothing to worry about.
do schools not teach the ideal gas laws any more?
Boyles Law is not really applicable here.
If you have 1psi in your kite bladder at sea level, the air in the bladder is also overcoming 14.7psi of atmospheric pressure.
Air pressure in a plane hold is about 10psi (say 5psi difference). The cargo hold of planes is pressurised!
So your 1 psi of pressure in the bladder would become 6psi of pressure in the plane.
So you would be basically packing your kite with inflated bladders (soft inflation) to have them possibly pop in a plane.
If you take a bike on a plane you don't worry about deflating the tyres as the pressure difference won't blow them out. A normally deflated kite won't be a problem.
I wouldn't be buying the kite from the second vid. Dragging a kite on coarse concrete can burn holes in ripstop. Also if you fold the leading edge and trailing edge in before folding in from the tips will reduce the size. Removing battens is a good idea and you may have noticed kites used to have foam around the valves when new. I have never tried sucking air out of bladders but it might allow the bladders to get a twist when you reinflate it.
All this means jack anyway!
Who puts their deflate valve back in after deflating anyway
At worst I put the velcro over the valve if I have a wet kite full of sand to help prevent the sand ending up inside the blader
