Any and all of the controls can be reversed, if you so desire. However, you will have a hard time finding someone who will train you if all of your surfaces are reversed. Also, even after you have soloed, let's say you are flying, and all of a sudden your eyes start watering, or a bee stings you, or something silly. You have to quickly pass your radio off, and the "pro" you pass it too promptly plants it in the ground because you want your controls reversed for some reason.
Use the traditional configuration....elevatorpush up for down, and pull down for up (it's akin to full scale, where in on the yoke is down, and out on the yoke is up).
The others,,,,,why in the world would you want those reversed?
Also, if you want the elevator on the left stick instead, or some other combination, this is possible too, and is called modes. There are several modes of transmitters, you can look them up. The most common are mode 1 and mode 2.
