Once I learned to use rudder in my turns it changed the way I look at planes in the air. I just got some video from AMA of people flying planes, and half of the guys didn't coordinate turns; looks strange watching a plane go around a corner with it's tail hanging down, especially the scale war birds. They don't let just anyone fly a plane in the military, and I would bet that the guys that do make it use rudder in their turns

Practicing this on RC planes even set me up to fly a full-scale cessna. There's a little indicator that shows if your tail is in line with the plane, and it was second nature to use rudder and keep the tail up. You can really feel the difference - has much more of a tracking feel.
