Do I have to disable all Slew Axis presented in this posted image? I will have to do the same for P3Dv4 and P3Dv5 as well
You should do this for *every* controller you have. Especially if you have some you don't normally use for flying, those are the ones easy to forget, that are usually left not calibrated, and always caused this problem.
And yes, you should do that for FSX and P3D.
