Do you mean the defaults? In that case I doubt it.

There aren't too many 3rd party aircraft available for FS2004 yet. Those that are would generally be updated FS2002 designs. It is possible to convert these for CFS2 by manually editing the MDL file. There's a tute posted on the CFS Home page. This is quite complex & unless there's no alternative I think it's a waste of time & effort. FS2000 or proper CFS2 aircraft work best.

Angel_Maker. That looks fine but you could have done the same thing by copy/pasting the F6F3_HELLCAT folder into the FS2002\Aircraft folder. As it has its own panel & sound it would work fine. For 3rd party aircraft without their own panel and or sound the appropriate CFGs would need realising to default aircraft before they would show on the selection menu.

The FS2002 Aircraft Editor is not included with FS2004. Most people here agree with me that it's a very buggy piece of kit & installing aircraft or editing files manually is much easier.
