Need some help here. I'm trying to get the settings correct with my Truetrak Vizion 380 auto pilot and my 5600. I fly a Glasair Sportsman with an IO390.
My issue is that when following the heading bug (or NAV track also) the plane moves left 4 degrees then right 4 degree constantly and I don't know which settings to change to make it stay on heading. There's the LAT activity on the TruTrak and the Roll gain on the EFIS. I'm trying to find the right combination to have the plane turn and stop on the heading bug without constantly moving left and right. The manual gives some starting points on settings but I can't seem to figure out which way to go on changes.
Any help would be appreciated..
