I have an older version of it, but I guess the basics are the same. You can't assign on-off functions, because there is no switch, just a pot. The centering makes fine tuning use impossible. I've experimented with several functions besides the obvious rudder. It seems to work with some view settings like moving back and forth, or left to right in the cockpit, although the centering may not work properly. It would probably also work like the x- or y-axis of the stick but that wouldn't be handy. For fine tuning an axis you'd need a pot which will stay in the position you roll it.
