Interesting, for those who learned to fly in tail draggers, our first rudder lesson was on the first day of training when we attempted to taxi a J3 Cub to the runup area. After that, every flight was a rudder lesson, from takeoff, to keeping the ball in the center, landing rollout, to taxing back to the tiedown area, all rudder (heel brakes too), a rudder dance. After that, we could fly pretty much anything.
