They move in the same direction, that's true, but you have to set it up so that the pushrod is on the right side on one, and the left side on the other (push rod goes on the outside of the servo on each side). I believe this is the same even if you slave the channels together; channel 6 would mimic what channel 1 does, so would operate in the same direction. It's all about the physical set up.

Read this forum. RCKen had posted a diagram. I think it's the third posting in this topic.
