I am getting ready to install a servo for each elevator half on my first gasser. I am using Hitec digital servos and I also have just got a Hitec programmer but have not used it yet. I am looking for the best way to set these up. Should I power them up to center the servos and then just put on the control horns or is there something else I should do? I assume I will have to reverse one of them.

Thanks in advance.
