Hey guys I have an original 4910 T-Maxx and when I turn the truck on the throttle servo constantly twitches. It will center wherever I have the trim set, but moves rapidly back and forth about five degrees in each direction. If I apply throttle it will also twitch at any setting I move the servo to. If I switch the channels on the reciever neither servo twitches at all so I don't know how to tell if it is a servo problem or a transmitter problem. Has anyone had this problem before?
