Helly everyone, This is my first post on X-pilot.com i'am from Holland som forgive me for my bad spelling sometime. I recently bought the CRJ 200 airplane on X-Aviation because i really like this airplane. But as soon as i initiate the autopilot to maintain altitude the cockpit starts oscilating, first it goes all the way up and then all the way down. As it's goes down very fast the engines turn off automatically. I tried almost everything but there seems to be no remedy. I run X-plane 10 in a new Imac27. Has anyone of experienced something like this and does anyone know how to fix it? Thanks for your time!
