Trim aileron on FW190

[Whacker]

Unless some of the old salts want to disagree, my experience is you'll never find a "perfect" combination of settings that allow for hands off flying.

These are old birds with no autopilot. Even driving a car, one is sending dozens of micro-corrections through the steering wheel each minute. I tend to find US planes the easiest because most all of them have three trim inputs and they can be cleaned up nicely. That said, even the german or brit fighters can be put on a pretty darn straight and level course with the right trim, but you'll always need to input small corrections from time to time to keep on course and at proper altitude.
