He starts turning back (nose up), at 3:23, hits the stop at 3:28. That's 5 seconds.

Don't know how many turns or what starting position that was from though. But judging from the paint chips on certain parts of the wheel only appearing once, I'd say that was not even a full revolution.

Yes exactly, we don't know by how many degrees he actually trimmed the a/c. There is a cut and change of camera position to take a shot of that area. It seems like he's been turning the wheel before the cut as the hand is already in the movement. Great find anyway, you can actually see the gears and the chain speed. This person grabbed the wheel 6 times doing sort of 1/5 turns so I guess you're right, it appears to be a one full turn +-. Only assuming that he started in neutral position (0) and with 5.75 full turns for full range of 11 degrees, it seems to give us a good picture about the operation.

It looks like the original assumption was correct and this is not correctly represented in the sim at the moment. The problem is with other a/c, too (and their rather too swift and easy elevator trim response) but the plane benefiting from this fact the most (due to RL vs. sim discrepancies) is the 109.
