I have a spektrum dx2 radio installed on my rc truck. I am suddenly having a problem. After powering up the transmitter and receiver, the throttle/steering servos just keep stuttering all over the place, and I have zero control over those servos with my transmitter. Even if i power down the transmitter, the servos keep stuttering. Is this a problem with my transmitter and/or receiver and/or servos? Any input would be greatly appreciated.
