You can center the surfaces from the sub-trim menu. Or you can just use the trims on the radio to center them. But I will stress this, get them centered as much mechanically as possible FIRST! Use the radio as a last resort. Between centering the servo horns, and adjusting clevises, you should be able to get very close. Mechanically first! If you get in the habit of centering with teh radio, then you will wind up loosing travel in one diretion or the other. Not a big deal on a trainer but when you're trying to fly a 3D plane it can become and issue. Mechanically center them as close as possible FIRST!
