How long do you go before you change your Transmitter Battery? I got mine the first of December and flew about two 10 minutes flights daily and finally changed batteries at the end of January (2 months). They showed about 10.7 volts. I figured they were 12volts when new (1.5volts x 8) so they might be low. Moved them to a shower radio that eats batteries monthly and its still going strong everyday almost 2 months later! Guess they were still good.

Anyone get the low voltage light on the TX and then replace. I don't want to let it get that low, but there's no way to tell when they are getting weak.

What kind of batteries do you use? Nimh, NiCD, alkaline, Sanyo, Energizer, Duracell??
