If you send us the file of the current configuration of your control unit, we can give you more reliable answers and make less assumptions (downloadable from the control unit through the command of the Windows software from the "File" menu at the top left using the item "Save Config to file ...":
Have you already performed all the steps provided by the Wizard?
If not, you must first complete the setup in the order provided.
Then:
First check that you have selected the correct servo used for the tail in the "Servo Setup (Output)" Wizard panel.
If you selected the wrong refresh rate, the tail servo would only work from one side (as already clearly explained in the side instructions of that panel).
If the servo is not moving from any side (or if it is moving but moving very little), you most likely set the tail gain to zero in your transmitter. Unless you have set the Proportional Gain "Is set in Software" in the "Tail Setup (Output)" Wizard Panel.
