For those people who have installed the "UAW160 Ardennes" stand-alone folder, or have added the recent Ardennes update to their UAW160 folder.
I had made four more planesets by editing the original one. Unfortunately there was an error in the original "FMDir.set" which was passed on to the other four

The P-51D slot had the correct skin, but the flight model was for a Spitfire.
The fix is here:
Planeset Fix Run the downloaded "BulgePlaneSets.exe" in the "UAW160 Ardennes" folder or the UAW160 folder and let it overwrite folders and files
