RE: how to change futaba`s t6xas battery?
It's just a futaba J connector like your reciever battery. At least my 6XA is. Just pulls out. Kins of a pain to get it back in becuase it's so far inside of it. How much do you fly a day? I get a good 3.5 hours out of mine. That usually spread over 6 hours on an active weekend. I then have a quick charger if it come to that point. It also isn't a good idea to always leave them charged. You do need to get the battery pretty low once in awhile to keep it cycled. let ti get down to 9.6 volts. The low alarm goes off around 9.4
