I fly with all of my controls at the very top of sensitivity...no curve.
However, I started flying this way from my first day in Aces High, so it is natural to me.
I will suggest that since you are transitioning from twisty to rudder pedals that instead of thinking about scaling your rudder pedals, put them at the top of sensitivity and practice Offline, or in the Training Arena, or Dueling Arena, and fly to what you see and not concentrate on the rudder at all...let your eyes tell your feet what to do. Soon you will recognize when you are slipping, and not turning.
In short, don't think about it...it will soon become intuitive...just like walking down the street, or climbing up and down stairs. But, just like a child first learning to walk, you will fall down and bump your nose. Just don't think about it too much! Let your muscles and brain relearn without pressure to perform like an Olympian and the transition will come naturally.
I hope this helps.
