My plane is banking

[FearOfHights]

Hello pilots!
I just got this game, and after reading a little here on the forums, it looks like that was not a good investment. But I disagree, I simply just love it...
I`ve been fiddeling with my controls, and I set up my xbox controller for now, and it works pretty well. I`m getting a flight stick in a few weeks.
So I use the left thumb stick to fly the plane, the right for looking about, and on the pad I have trim nose up and down and rudder left right.
Still, every plane is banking to the right, and it`s very hard to fly in a straight line.
Am I missing some trimming? I just assumed that rudder trim would be the right one to fiddle with to counter the banking. It help a bit, but not much. That is the only thing that irritates me a little, allways have to correct..
Allso I cant find the auto pilot enable/disable in the settings.... I want to use it for longer flights, and just forr keeping up with the ai

FOH.
