I agree; replace the battery with a new one and you should be good to go! If you have any doubts just send the radio to Radio South for a checkup and cleaning. Since so many people have gone to 2.4 technology most of the interference problems where I fly have gone away. My 72 MHz radios still work great although I must admit I am slowly changing over to 2.4, both Futaba and Spectrum. I use the Spectrum because Horizon offers some neat bind and fly airframes that don't work with Futaba...
