how do i get my servo to hold neutral positionwith full force

[Jakyat]

Hello all. I am still a newbie when it comes to radios and their capabilities. I am using my right joystick up-down (elevator??) to function my winch. I would like to be able to use one of the 2 position switches to turn the said channel off and on. Can anyone steer me in the right direction or post a link to an earlier thread that would help me out.
