Spektrum DX7 voltage
My DX7 on one model memory shows low voltage ( falls as I'm watching) and on all other model memories it shows good voltage. This is after a full charge and I've checked it with a volt meter. The charger is working right and the battery in the tx shows 12+ volts. This model memory is one that was started to program exponential on my plane to cure it's twitchiness. The problem with this is that the tx shows low battery and shuts down. I can of course fly on the other memory, but I don't like unknowns.
Any help appreciated,
Ed
