One Wing Low (not chinese pilot)

[resojames]

I installed a 2 axis system on a W10 Wittman Tailwind.  I don't think my problem is a autopilot problem, but rather an aerodynamic oddity of the boxy sided Tailwind.  My plane will fly one wing down about 5 to 7 deg in a perfectly straight line in track mode or nav mode for as long as I can stand it.  It does seem to favor the right wing low mode however it will fly left wing low sometimes.  Almost never will it fly wings level.  Are there any adjustments that could help in this matter?

Thanks
Andy

There is a good discussion of this in this thread:

Basically, the AP is correcting for an out of rig condition in the plane, generally yaw trim. The AP only has access to the ailerons, not the rudder, so all it can do to fix any yaw errors is to lower a wing. There is no "adjustment" for this since if it rolled the plane level, it would start turning.
