Man, I honestly don't know if the servos will go in seperate directions, but I think they will. I always setup my dual aileron ( dual servo)planes on different channels. If one is moving the wrong way, it's as easy as reversing it. They can be fine tuned a bit better if they're on seperate channels. I'm a bit of a control freak I guess. Plus, it helps out a lot with aileron differential, more up less down movement.
