a ordinary kite pump has almost exactly 2.6 liters of air in it. All my pumps leak right now but when they were new and pumping good it took about 34 full pumps for them to fill my 3 strut 10m envy up to where there was no pressure but the kite was roughly inflated this is 89 liters of air.

u know what I just realized my envy is 3 struts not 5 that's why our numbers are different.

now I am confused! one or the other... :D


would you care to elaborate a bit more?




It means that yes, it is a noticeable advantage over air.

By noticeable advantage I mean a BARELY noticeable advantage.

As in you barely notice the advantage.

As in you barely feel anything different.

As in there is not that much of an advantage since you can barely feel any advantage.

Yes, I have done this many many times ( at least until the cylinders of helium gave out ).

There is not any worthwhile advantages to using He (unless you count a barely noticeable
increase in advantage worth it).

ok given your 89 liters then a 10m 3 strut kite is going to have negligible difference, howevr my calcs could very well be representative of a large 5 strut 17-18 m race kite.

Helium is also a non-renewable resource we're in danger of depleting in the next 20 years. Helium is used in the medical industry and for supermagnets, and no helium means no MRIs.

obviously hydrogen would work better
but
either gas
being made of smaller molecular particles
would escape normal kite bladders and your kite
will have gone flat quickly
