Not so much here but in warbirds.............. you go to extrenal view and zoom in on the elevator while you are on the runway, pull the elevator full up and note it's position, hit the trim up and watch the elevator move 10 or more degrees extra.
This helps some flight models and hurts others.
That said, flying with combat trim off is great because we can always hit either level trim or trim for angle which will near instantly optimize trim for whatever speed you are currently going.
The only downside is accidently hitting X instead of Z when adjusting your field of view during a turn fight.
