This brings up another common mistake I see beginners make. They will move the stick and then let go of the stick and let the springs return the stick to it's center position. Bad, bad, bad. This causes lots of problems. First of which is that the springs will actually move the stick past center before actually centering the stick, which will translate into movement in the plane. Next is that now your fingers have to "find" the stick again, this means that there is time that you don't have any control of the plane because your hands aren't on the controls. It's also very possible to move the stick when you put your fingers back on it again, once again causing movement in the plane. What needs to happen is that when you move the stick you then need to smoothly move it back to the center position after you are done with your maneuver.

Hope this helps
