Select “Controls”, then “T-Rudder” (should already appear in the Controls list – may have to scroll to the right)

Set the control options as follows:

Left Brake Axis Joystick L-Axis X
Check Reverse Axis box

Right Brake Axis Joystick L-Axis Y
Check Reverse Axis box

Rudder Axis Joystick L-Axis Z

Took me a long time to find this solution. To turn off Auto rudder coordination, press Shift + Ctrl + U (I did that during flight). You need to turn off Auto rudder coordination in order to use the actual rudder pedals with the simulator.
