No, it DOES move, slowly, with the trim sensitivity to adjustment that you would have in RL.
But it would seem you want 3+ player is a forum, to force a change on 5 Million+ MSFS players.
Personally, I don’t care how it gets changed, as I can easily implement my own “over-ride” control wishes with AAO or Spad.
Having reviewed the Asobo code that is doing the elevator trim function, (which already has other bugs and issues), the chances that any change to this code will result in something else getting broken in a far worse way.
