autopilot hunting

[LouRubin]

Ive got a HDX installed in a Lancair ES. The CDI is centered tracking a GPS waypoint and the AP wanders 10 degrees left to right
It doesnt seem to want to stabilize

I would suggest reviewing Dynon's updated "Autopilot In-Flight Tuning Guide", linked below. If roll axis tuning is complete per the document and the issue still exists, see Section 3.1.5, "Roll Tuning Troubleshooting".
