Ailerons are used for turns. Elevator is also used due to the fact that some of the lift is now being used to turn the A/C. Rudder is only used to compensate for some of the side effects of maneuvering, such as adverse yaw and P-factor. In most smaller planes these side effects are subtle and don't need to be corrected for successful flight. Your best course of action is to read up on the basics of flight before you get into the air. It can be the difference between a good experience and a bad one.
