how do other people manage trim?
I fly with CT on for the majority of the time Im flying. Its a convenience factor - dont want to be constantly adjust trim for straight and level flight.
That said, in any sort of low-speed engagement where control surfaces are being fully used, I will always trim in accordance with the maneuver.
For example, if Im in a 109, fighting an AC with a better roll rate, like a 190, and he's rolling left, I'll trim ailerons to port to increase my rate of roll. Or, if, again, Im in a 109 fighting against an AC with a better sustained turning ability, Ill trim elevator heavy to maximize my ability to get the nose around.
In stall situations, fighting the vertical, I'll turn CT off where it stands. CT is a great system, but at very low IAS (over the top, for example) it seems to try and resist what you want to do with the aircraft. Like a car's traction control on ice, it just gets confused and ends up hurting rather than helping.
