Hi jlazyr
I'm not with Laminar Research, just a fellow simmer in the UK and you may remember that we have corresponded on this matter before.
Unfortunately you will not get an answer to your specific question here, as this Q&A forum is for simmers looking for guidance on XP11 from other members of the flight sim community.
As I believe that you purchased the Khamsin-T28C aircraft from the X-Plane.org site, you will have to refer your question back to them directly, which I believe you can do at
[email protected].
Hope this helps
Regards
