In anticipation for this, I've finally decided to follow the advice of a lot of people regarding elevator trim, and have added two new controls to my control bindings, which are a quarter of the trim inputs, and allows for much finer elevator trim control. Much much easier to achieve hands of flying now, well worth it imo.
Its actually very easy, first navigate to here,
Open the 'default' LUA file, and copy in the lines (use something like Notepad++).
to here, the --Tail Trim Wheel-- section lines 525,526 in my screenshot.
Save and open the game, now you will have 2 new commands you can map,
Trim Elevator Nose Down Slow
Trim Elevator Nose Up Slow
I've still got the original commands mapped for fast adjustment, but on my HOTAS the new ones. Well worth doing I think.
