The most powerful control on any airplane is wrong rudder.

The Barnstormer site has some of the best info I have seen. I have been struggling with inverted rudder corrections myself. If you have to think about you won't do it right. Just keep practicing it until it is automatic. Fly lots of double I's and Outside I's pulling and pushing the nose with rudder. Also, Cubans with out rolls, vertical 8's, etc. Even inverted flat turns and figure 8s. Also, use a stick plane and think out your inputs as you dry fly it.
I have been trying spend a few minutes of every flight and am now at the point I push wrong rudder upright! Hopefully soon it will become automatic.
