Thanks for the reply @danhenri and @POM. Is that the general X-Plane community view? It's interesting how some publishers, like Carenado, mention turning it off, and others, like Aerobask, do not. I wish that there was more consistency regarding this. It leaves one wondering if a developer designed their aircraft's FD around SA being at the default of 50% or at 0%. In other words, does a developer assume that everyone will know to adjust from the default if it's not mentioned in the docs? And if that's the case, I wish that the default in XP would be 0%. At least in 11.3x we'll be able to assign custom response curves per aircraft.
My joystick uses Hall effect sensors so noise is not a problem.
