OK. So now you will need to to some testing.
Remove all the plugins from your plugins folder (except Gizmo). You can't just turn the plugins off, you need to remove them.
Launch X-Plane and re-load the Saab and test. If you still have problems then post your log.txt from that session.
If everything is working as expected then put the plugins back in the folder one-at-a-time, reload the Saab, and test again. If, after you've put back a plugin, the problem returns, then that plugin is causing a conflict.
