The textures on this model are compatible with FS9 and FSX
DHC6-300 textures from models with VC, but not with earlier 'GlobeTwotter' models.
You can add texture folders and expand the aircraft.cfg file
with additional [fltsim.x] entries in the normal way.
The only extra thing you must do is to copy the four
files below, from the texture folder of an original
-400, into the new 'transplanted' texture folder.
Overwrite existing files where prompted.
