Please look into this Laminar Research. I have just "converted" from FSX to X-Plane 11 because it's supposed to be the most realistic flight sim with physics engine calculating actual lift/drag etc. but I'm left with a pretty bland experience when I'm flying with rudder pedals (Saitek Pro Flight Rudder Pedals recognized by XP11 and perfectly calibrated and all sliders far left for max realism) only to discover that XP11 is applying auto rudder for me as soon as I take off, so no matter my turn rates the "ball" never leaves its center position despite no use of rudder. If I perform a "realistic" turn with use of rudder I'm just destabilizing the turn instead.
Clearly the auto-rudder is interfering with the controls when it is supposed to be disabled as I have rudder pedals attached, recognized and calibrated correctly.
This was the worst part of Xplane for me but I have some good news. It's been solved! You have to use Planemaker and make a custom version of your plane. There' a setting in PM called "Rudder tied to aileron" that you can set to a negative number (I use -0.8). This makes the slip ball deflect all the way in turns like you'd expect it to.
Just edit that value and save the plane
