TSquare,
Yep, I just keep the sound folder in the stock default folders (except A6M5 and the AI only) for sound aliasing. And rewrote the qc_plane.qcb in the QUICKCOM folder with Notepad (replacing the WWII aircraft with WWI aircraft). I think there maybe a tutorial somewhere on the qcb file, but I am unaware where it maybe found, or perhaps there maybe a different method others have been using other than editing with Notepad. Also there are other entries that can be removed for the default aircraft such as the mdlnames file in the CFS2 root folder. Perhaps someone can elaborate more about it. The more ideas the better.
