An update to the installation:

The XML files are in the wrong directory for the -100F, -200 and -200F.
The -100 is in the correct directory.

The '727_various_fixes.xml' needs to be moved to each respective \panel folder:

FROM:
..\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\CS_B727-100F
TO:
..\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\CS_B727-100F\panel

Repeat for the -200 & -200F

Sorry about this but errors can happen  :-[
