Futaba Throttle Channel Not Working
Trying to use my Futaba 9CH TX with a 4 channel GWS narrow band receiver on my Graupner Terry. Has a speed 400 motor from Graupner with a built in ESC. Can't get this radio combination to control the throttle, other channels (airleron and elevator) work fine but no control of the throttle, have tried reversing but no good? If I move the control cable from the ESC to channel 4 (rudder), when I move the rudder stick, the motor control works as expected (although all the control is on the right side of the stick). Can't imagine what this would be but probably something simple. If I replace the TX/RX with JR components, it works fine as well.
Doesn't seem like a problem with the ESC unless it is a compatibility issue with the Futaba but not sure why it works on the rudder channel.
Thanks in advance.
