What you saw was a plane that was in the hands of a good pilot that new what to do. He might have made it look easy, but don`t be fooled it took skill. This kind only comes with lots of flying time and good flying technique. I say that because a lot of people fly around and not use rudder at all. So when comes time for the left hand to kick in it remains frozen with the right hand doing the work. That may fly on a single engine but believe me it will not on a twin with an engine out or on many large scale warbirds. Guarantee you will loose the plane.
