That is right . My flight instructor used to tell me to " Step on the ball " It co-ordinated the turns . Same thing when we fly RC . we need to co-ordinate our turns with the rudder . I agree with Eddie C I like to use both rudder and ailerons to turn my cubs . I find if I don't they will drag their tails especially if your speed is down . If your speed is up its not so bad . I like to fly fairly slow though . Not to point of stalling but slow enough that you are flying on the wing .
