I've flown a few that couldn't even be trimmed for slow flight or approach

cruise.

Interesting. I was flying my simulated Cessna 182 and it didn't seem like the
pitch trim fully deflected the elevators even with the trim all the way over
(that is, I could still move the yoke to get even further deflection). It
sounds like this is true to life.

Specifically, I've been trying to practice slow flight, but it seems to be
really hard to get the aircraft anywhere near its minimum speed. During the
course of this practice I noticed that even trimming for full nose up didn't
seem to actually get the aircraft down towards the bottom of the green band,
so I was wondering if it were really possible to trim it that far. It doesn't
sound like it is. I'll have to try holding the yoke to fly really slowly.
