how do you know which dx7 you have - a v1 or a v2, or is that the battery that has the versions? - the nimh batt mine came with charges from the plug hole and i know that's backwards from normal
it's just the csrc lithium Tx packs =) or atleast as far as I know.
No idea on the dx7 how to tell the difference between the revisions except opening it up and looking for a rev stamp on the board, or look up on the net and see if someone's got some pisc of diff board revisions and where parts are. That is if there is different revisions of it... I really have no idea =)
