    Is am not sure how well it will work to reduce adverse yaw. It should help some. Are there any options to adjust the gains or aggressiveness of the yaw damping function?

      Isn’t a yaw damper there just to prevent tail wag during cruise? Never thought about it as an adverse flaw fixer upper. But I’ve not seriously flown behind an autopilot, either. I did make funny faces once, though.

        That is it's primary function, but yaw is yaw, and adverse yaw should be reduced as well I would think. The inertial reference senses it, but it doesn't know where it came from. Every aircraft design is different, with different yaw characteristics. Hopefully there is some adjustability to the response of the yaw function.

          Dynon does have adjustability, but the problem is that until they put out documentation about how the system works, it's just guesswork.

          John, I'm flying the G3X touch system with the 307 A\P controller. I elected to forgo the 3rd axis (yaw damper), but could easily add it at any time. Your question about adjustability is a good one. The installation manual, for the G3X system is around 860 pages. It's available from the Garmin site. And no, you don't need to read and implement everything on all those pages. There's just a lot of information about every aspect of installation and getting the system ready for flight. I'll admit that it was intimidating at first. I learned to really appreciate the detail and depth of information. The section about autopilot configuration is about 60 pages. Again, you don't HAVE to spend untold hours on the minutiae of the system. You can, however, adjust torque - response speed - and sensitivity of each axis, independently of the others. So, to answer your question, yes, the Garmin system can be tailored to your liking. I'm quite certain that the other manufacturers systems would be similarly adjustable, but that's just a hunch.
