[A/C goes nose up when activating autopilot]

Just confirmed nothing to do with the yoke. Apparently, if I cycle the AP on and off a few times, the subsequent engagements are ok. Sounds like another bug to me!!!

[A/C goes nose up when activating autopilot]

It’s been happening to me on both xplane and the crj. On xplane, I found out it was because my ch yoke doesn’t go fully back to its neutral position when released. Let’s say that the hands off position is between 0% forward and 5% back pressure. I was trimming it to 5% back pressure. Once the ap was engaged, it was being overriden by this 5% and pitching up. Therefore, try to make sure that you are trimming the aircraft and engaging the autopilot when your yoke is dead on centered.
