and its just the opposite when you move the pushrod on the servo arm.

move it away from the servo and you get more movement
move it closer to the servo and you get less.

also if you have a computer radio you can adjust the movement just by using your radio setup
you can go more one way and less the other and with expo you can make it have more or less movement in the beginning of stick movement or more or less in the final movement of the stick[&:]

getting confused yet?
