It does take alot of practice. I used the simulator to teach myself rdder control. When you have the plane inverted and flying towards you, the rudder will move the nose te same direction as the stick, which is opposite of upright. once the plane passes you the rudder will now move the nose in the opposite direction of the rudder stick. It took me alot of crashing on Realflight to get it right but once you get it, the muscle memory will become automatic. Good luck!
