Garmin Autopilot w GNC-305 Doing gradual s-turns

[Dave Anderson]

Any autopilot experts

I have a Garmin Autopilot w 305 head set-up in my bristell, it makes these very gradual s-turns when flying a NAV course It's almost enough to rock you to sleep but very gradual

I'm trying to understand what setting would help with that, that seems to be a gain issue on roll?

My current Roll settings are torque 80% (seems high) Servo gain 1.0
My current Pitch settings are torque 80% and Servo gain 15

Check the tensions on the aileron servo cables and the aileron cables themselves. Make sure those are tight before changing settings.

Check the tensions on the aileron servo cables and the aileron cables themselves. Make sure those are tight be fore changing settings.

This was the problem on mine. Just about an 1/8 inch of play but getting rid of it resolved the problem.
