Just remembered. One time after putting my transmitter back together again, I had no rudder control. Took the transmitter apart, connector looked OK and potentiometer wiring looked OK. Pulled connector out and put back in and it worked again.

DH9104 49MHz transmitter connectors:
1 - Throttle
2 - Backward/Forward Elevator
3 - Left/Right Rudder
4 - Backward/Forward Trim Knob
7 - Left/Right Trim Knob

Never did figure out why there are 5 distinct proportional inputs to the controller integrated circuit. Maybe it is a 5 channel transmitter - someday I will drag my oscilloscope out and watch the waveform to see exactly what is being transmitted.
