What Art said and more! I teach rudder use as soon as the student grasps "pull" for up and left and right aileron. Normaly this is on the second or third flight. Aileron use on landing will cause the wing to dip. If you catch one (wingtip) on landing the airplane will "cartwheel" which will do more damage than one can imagine. Use of rudder will align the plane to the runway better and keep the plane flying. Rolling (aileron use) will shorten the effective wing length and make the plane dive. EXCAP232
