What is "trim"/"autotrim"

[cajun]

What is it and how do I use it??

Any time you put your plane on one of the 3 autopilot types, it automaticly trim's your plane for the current speed.

BTW the 3 auto's are X = Level, Alt X = autoclimb
Shift X = Auto angle. (whatever nose angle the plane is at it will keep, up or down)
