I'm trying to get to grips with the PID tuning stuff using X-Plane
Using various GA aircraft, they would all snake when going from Waypoint 1 to Waypoint 2 and back again. I could get them to "stabilize" without too much oscillation, but the aircraft would roll oscillate in trying to follow a track.
When I load up the "Radio Control" example plane - a Great Planes 60 trainer with "stable trainer like handling" all the nav course following snaking goes away immediately, no PID tuning required, same values as the ones troubling for the GA aircraft.
Why would that be?
How do I find search for smooth autopilot settings for General Aviation craft, even the very simple one like the StinsonL5 (high wing trainer)?

The nav tuning guide is in the manual here.
