Flying an Addiction myself, maybe I should give that a try too.

What I currently struggle with is that the Plane slowly rolls to the right in inverted flight. It's marginal but it's there. Any idea what could be the source for this? I noticed that my rudder has to be slightly off center for normal flight (trimmed to the right) but side thrust seems correct. (no corrections needed in vertical upline). Also checked that elevators are aligned and travel the same way.
Good ideas for reasons are welcome ....

Best,
Malte
