I found answers to my problems and others problems described in this thread.
-
Inverted flight controls, ailerons was due to reverse axis check box was not ticked for som reason. Ticking it of in control options fixed that.
-
sticking rudder was due to for some reason the trigger button was suddenly assigned to the control options rudder right/left (yaw right/left). The fix was clearing those assignments and asigning the triggers to the option rudder axis right/left and leaving the reverse axis boxes ticked.
Hope this can help others on xbox and with xbox controllers.
Have a nice day.
