Hi all, I have had the Dynon AP installed and working since November 2015. It has worked great since that time with only one little thing that I can’t even remember has happened all the time, or I have just noticed it recently. After about a half hour or so of flying straight and level on the AP, it starts to hunt about +20 feet to about -20 feet of my selected altitude. My rigging is nice and solid with no play at all. There is no change in wind conditions or any other thing I can identify. It’ll hunt for a few minutes, maybe 5-10, and then go back to normal. It’s no a show stopper by any means but I’m just curious if others have seen this. My software/firmware is always up to date also. Anyone experience this?
