I tested this and found yes it is too quick and smooth to roll the trim wheel through the whole range of motion. The thing is in a combat turn you don't want to trim the stabiliser more than a degree or two. So red players are not disadvantaged because blue 109 pilots will never want to move it through the whole range of motion unnaturally quickly.
It would be more realistic if the trim wheel moved a little bit slower and in little bursts to simulate the motion of a hand turning the wheel. In practice though it hardly makes much difference.
What I did discover though is that flying the 109 with little adjustments of trim is a very good way to conserve energy and keep the top speed up. I have now bound the trim button next to my throttle so my left hand can easily adjust trim
