Hello everyone, today the RV and I were shooting an LPV with my new to me 430W and noticed with autopilot on it follows glideslope insanely well but about 4 miles out from the runway it wasn't keeping the HSI centered (about 1/4 scale off by the time I got almost to the runway). I have gone through the usual autopilot tuning guide and it holds altitude and speed very nicely. Any ideas where to start or is this somewhat typical? If I hand fly it I can keep everything centered real nice and looks great out the window; just thought the autopilot would be able to the same, must have a setting screwed up somewhere. Thanks for the help!
