FS9.1 build 40901.01, no additions, default Learjet 45.
Did something to this plane and it's now impossible for me to trim it to wings level in cruise. Have the same version of FS9 on another computer and there's no problem trimming the Learjet. I've done very few changes to my aircraft configuration files and only one to the Learjet in an effort to correct this problem. Fuel load is even, aileron trim centered.
Using rudder trim changes the wing low situation resulting in either left or right wing low with no setting yielding wings level. Tried reducing rudder trim effectiveness (first config file change for the Lear) and that helped a little but still unable to get wings level.
Anyone have any ideas what I might have done to cause this? Or better, to correct it?
