Would you please elaborate on this...i.e. AH trim vs manual trim? I have rudder & elevator trim set to one of the 4-way hats on a CH throttle. Is it best to turn off combat trim before inputting trim?
Appreciate it 
optimal trim ( especially rudder ) will change during the flight depending on maneuver/engine power/angles etc.
If you hit "auto trim", it will take second or two, level your wings, generally unadvisable in combat.
hitting CT on and off gives you perfectly trimmed aircraft right away, no matter what position you're in.
I guess there is an argument to be made for having a macro toggle it on and off every couple seconds, though it feels "gamey"....
