AUTOPILOT FINE TUNNING IN ROLL

[q2cjiii]

I am trying to fine tune my AP in roll, with track/alt engaged
I move the track 90 degrees, the a/c moves to the new heading, but over shoots, rolls back, crosses the course turns back and crosses the course again, it is like a signwave. I have ran the sensitively up to 18 and the
gain up to 4, this does change the hunting effect, what do I do next.

thanks, charles

I am just starting to set my autopilot up and also have something of a hunting oscillation on the roll servo. I have turned the sensitivity up and it has helped, but would love to hear the best way to tune out this "hunting sine wave"
