Hey everyone, while finishing off this build I'm now working on the elevation. All hookups were made as per the instructions, but when the tank get turned on the elevation motor starts spinning uncontrollably, and the relay box clicks non stop like an old mechanical typewriter.

I checked to see if the radio channel (#1) is set to Neutral, which it is and when a lone servo is hooked up has proportional drive. I also experimented and plugged the elevation into the same channel that has been working perfectly for the rotation, still the same outcome.

For the Radio I'm using the Futaba T8J

As always any help is appreciated!

Does that mean the fault moves with the motor/wiring loom ?

Hi John, on the Motion Control Module try pushing DIP SWITCH 1 into the up position.

Switch Description
1 ON = Newer Transmitter systems with faster transmission rates (e.g FUTABA S-FHSS). DEFAULT POSITION
OFF = Older Transmitter systems with slower transmission frame rates (e.g FUTABA FASST and analogue systems)

Thanks everyone, It was the DIP switch, after flipping it, it worked like a charm! thanks!!
