I agree with redd bucky.
Personally I fly with CT off, and if I get the feeling that I'm out of trim I just hit control X twice.
Plane is trimmed, not perfectly, but its easy enough to do in the middle of a fight.
Partially depends on what plane your flying. 109's & P38 will take more manual trim than spits and Yaks.
Another alternative that I have tested, but not extensively.
Is to setup trim to use a 3rd stick set. You could use either SS3 or 4. Set a button to switch alternate stick sets.
(In SS1, set button to jump to ss3, in SS3, set the same button to jump to SS1, makes an alternating switch affair)
Then pitch trim is your forward, back on stick. Aileron trim is left right on stick, rudder trim is your rudder.
So if you get into a "need to trim manually NOW" click the button, trim it, then click back into flight mode.
