Hey
I think, I have more or less the same problem.
After pushback the aircraft can’t rolling away. But you can see the wheels turning. After restart couatl, the aircraft takes a jump.
I am also not able to set the pitch trim, untill i restarted couatl.
I fly with the FSLABS A320 Fam in P3D V5.
Thank for a solution!
Regards
Joël
