Hi 3D,
The easiest way may be to call us and we can walk you though it, (480) 460-2652. I don't know if make any option menu changes so I will assume not. To set up the first servo's center you move the selector to 1 and then use the push-buttons to center the servo. Assuming you did not set the "Priority Mode" in the option menu, you should have your second servo unconnected at this point (Two options that are very helpful in this situation are Priority Mode where servos that have not been setup are disabled and freewheel and the Endpoint-hold Mode where the endpoints are held even when you take your hands off the transmitter sticks). To set the endpoints (without Endpoint-hold) move the stick all the way to one side and then, while holding the stick there, use the push-buttons to set your endpoint. To do the other side just move the stick in the opposite direction and do the same thing. To adjust the second servo, just move the selector to 2 and do the same thing you did for the first servo. I hope this helps.
