Same happens to me. . .and not just the trim wheel, but the “selector” knob tied to “plus” and “minus.” They do not “spin” as in selecting an altitude and switching to 1000’s instead of 100’s when turning slowly. (Except for heading. . .but with the Working Title Garmin, only positive HDG increments work now. Doh!) See this other thrread for similar complaints.
I am out of time to try it out flying, but will check again tomorrow or possibly later tonight. It’s possible that the really (and I mean really slow) trim adjustments shown on the trim wheel animation are actually impacting trimmability in the air. I’ll check with the 172 and Baron and report in.
