Troubleshooting Auto-Pilot Issues

I still turn it off completely when it starts jumping about and yawing

Any aileron input will cause some adverse yaw. The G series ailerons may reduce adverse yaw but they don't eliminate it.

I reduced the roll activity but still assist the AP with rudder for turns to a new heading. The aircraft needs a yaw damper.

I thought the autopilot shouldn't correct more than I would. I might have it dailed back too much but it seems to work better in kinda bumpy air. I still turn it off completely when it starts jumping about and yawing

It can feel lethargic in smooth air but strangely joyful with a little turbulence if the gains are cranked way back, as I have also experienced. When it starts hunting, I usually adjust them a couple of times before giving up and hand-flying.

I had reduced roll gain to 0.8 which worked quite well in cruise flight with light turbulence. However, I found lateral control on RNAV/LPV approaches was sloppy. I have increased roll gain to 1.0.

The good thing is that it is adjustable in flight.
