I am running a 2700 mah nimh 6V battery. I have checked metal to metal contact, i don't have any long servo leads to the digital servos. I have tried a large capacity nicad batt and the glitch still occurs. It could be feedback from the servo that the pcm rx is covering up. I think i am going to purchase a better rx from futaba that isn't pcm and see if it will do the same. That is really the only definite way. Thanks for the input so far.
I also disconnected the voltwatch I was using because I suspected that it may be a possible cause as well.
