Hi James

In the FSX\SimObjects\Airplanes\CS_B52\model\ folder you will find the model.cfg (open it with notepad) that you will need to modify.

This is what you will see inside:

[models]
normal=CS_B52
interior=..\..\b747_400\model\B747_400_interior


You just need to change the interior=..\..\b747_400\model\B747_400_interior to point to the VC you want to alias it to.
EXAMPLE: interior=..\..\CS_B727-100\model\cs727_100_interior would alias the cockpit to the CS 727-100 VC. You must have these ..\..\ in there because they tell FSX to go back to the airplanes folder before moving on to the CS_727-100\model\ folder.

NOTE: BACKUP THE MODEL.CFG FIRST!

Hope this helps.

Mark
