Switching from twist stick to rudder pedals is pain, daily and it's lasting for weeks/month.
First you have to force yourself not to twist the stick, then you have to force yourself to move the feet instead, then think about which feet to move forward and someday you reach the point where you don't think which is the correct move you just do it like you twisted before. All that is left at this point is to learn how much you have to move your feet to be accurate again like you used to be before.
But you will get to point, where you realize that pedals are better and you never want to change back, but this is a long and painful way.
After 6 month now, I'm very satisfied with my simpeds vario USB.
