n2 tank questions... bad to leave it filled for long periods of times?

[SoupRman]

ok.. first off I'm going back to nitro but have noticed I always came back with an empty tank form the field or used it all up the next day on playing around with it.

anyways just wondering if its bad to leave it filled to the fullest or even half filled for long periods of times like, 2 weeks to 1 month just in case.

other questions:

Do you leave the field w/o out filling and just have whatever air is in your tank still in there?

Do you drain your tank of air when you put away your gun? and...

Do you get your tank filled before you leave?

Thanks guys :)

I usually get my tank filled before i leave, so i can shoot. It is good to leave some pressure in your tank at all times to make sure no dirt or anything gets in, and it is fine to leave it filled for extended periods of time.
