Your going to start some trouble in here with that comment

My friend who had/has been teaching me has been flying for 7 years and does some pretty good 3D stuff. I asked him the last time we were at the field on how and when to use rudder and he kind of blew the question off. So I wathched him fly and I never did see his thumb move the rudder stick other that to change throttle. So I wonder if the rudder is a lost art of flying only known by the masters any more

. This guy has taught more that a few of the guys that fly at our field and they seem to all have good flying ability's.
