Apart from problems with the autopilot (which is a question for another time) my newly downloaded Beaver (171229) does not fly smoothly horizontal and constantly pulls left. So I have to "level" it. Can you please write me step 1, step 2, how do I do that?

1. If you're using the plane as downloaded (the 171229 version), you aren't using the alternative flight dynamics this thread is about. You have to sign into the MilViz DHC-2 support forum and you'll find a thread called "Alternative FDE". You can download the updated files from there.
2. This Beaver definitely exhibits left turning tendencies in the high AoA regime, so if the problem is during climb at high power settings, rudder trim is your friend, and there is a rudder trim knob accessible in the virtual cockpit, up near the ceiling next to the elevator trim. Adjust to center the ball on the turn coordinator.
If the problem is in cruise and the ball is centered, you can use a little aileron trim. There's no knob in the cockpit for that, but this sim model does have it "activated", you just have to use the keyboard command for it. I think it's CTRL-num key left and right arrows. A couple clicks of aileron trim should stop the roll tendency.
