Redtop, Redd & TC are all correct.
All of the above.
I fly with more deadband on my rudder than any other axis. This sets the point at which twisting the rudder will actually start moving the planes rudder. Very handy for a twisty stick (I've flown them myself for 9 years)
Setting the sliders is also a good idea, especially if you want something other than
no rudder, then full rudder.
Adjusting the scales lets you find the right balance. Just remember no major changes at first, test what you've done, then adjust again.
Best way to test when you have it right is as a gunner in a bomber.
Panning the gun back & forth should not result in the bomber turning. If it does, set deadband up a smidge more, or sliders a bit lower on the left.
Once you can pan the gun back & forth smoothly without affeecting the plane, then try turning the plane from the gunners position. You should still be able to do so.
