dull batterys in the rx pack.. still got the jitters, im stumped[&o] i opened the receiver and it all looks good, opened what i could of the transmitter and in all looks good. i am useing a different battery pack to what i was 3 years ago, but its just one of them basic 4 AA packs for now. the servos im useing are the ones that come with the transmitter, which have expert s-25 on them, except for the throttle one, its a futaba s3003. i have tested all the servos in one of my r/c cars and they all work fine. any ideas?
