Thanks for all for your posts. I have the EXACT situation as ByBry. I really feel stupid as I have been in flight simulation for 30 years. I previously updated my CRJ-200 in X-Plane 10. It would not follow the FMS, thus I simply replaced it with the old version. A few days ago I jumped into X-Plane 11, downloaded my CRJ-200 v.1.7.2, and set up a flight. The result was the same. It will not follow the FMS. I made sure the Yaw Damper was on (lights off) on the console. ByBry stated he resolved the issue but did not state specifically what he did differently. If he would post that I would appreciate it along with any other comments. Thanks
