Aircraft always turn more efficiently with the use of rudder, because of adverse yaw created by the ailerons in a bank the nose of the aircraft tries to yaw causing the fuselage to be a very large air brake. The rudder is used to counter this adverse yaw and keep the fuselage streamlined while turning. It is also used for slipping the aircraft during crosswind approaches. And during takeoff to counter asymetrical thrust,p-factor and gyroscopic precession. And of course on landing to keep the aircraft lined up with the centerline of the runway. Trimming does not make the aircraft fly faster or slower it just relieves stick forces in straight and level flight and decreases pilot workload. Aircraft are normally trimmed for long climbs also. Actual trim wheels on your joystick are the best way to accomplish this.Hope this answers your question.
