There are some glitches with overriding controls.
Not sure if this is by design or a bug.

Example: I throttle all the way up with my joystick, collective indicator is at top. I leave the throttle there.
Now I use another input device, say my keyboard, to lower the throttle, it follows that. Logical so far, the last touched device determines current setting.

Now when you go into zeus mode and back, it refreshes the throttle position based on what the joystick's throttle is at rather than remembering the last set position.
