BTW try this please. It may also help remind you that this is not real. I use combat trim all the time, but I never leave it on.
When I transition from high speed cruise on autopilot, to a turn fight your trim obviously gets out of whack. Rather than leave CT on all the time, when I feel it getting strange.
I reach down, hit Control X, wait a sec, hit it again. I'm now trimmed pretty close for that speed. Not perfect perhaps, but close enough.
Its a lot easier than mapping a trims to 3 diff sets of buttons & trying to remember them all.
