OK. Let me have a go.
1. To make an unflyable AI only drone open the AIR file in AirEd & change the Aircraft Type from 0 to 2. You can delete the contents of the Panel & Sound folders to make the files smaller. I usually leave a dummy text file in the folders so they unzip properly.
2. Steve McClelland's CFII Europe Release 2 suits me. It's terrain mesh & includes over 80 airfields. Not the CFS1 default airfields but the mesh is compatible with the GZR & Martin Wright's airfields among others. *
3. Steve also did France in a separate release. It might be CFSII Europe Release 1 or 3. Try a search using his name. **
5. Steve Fairs did a Ju-87. Check out his site at Sim-Outhouse.
6. You should be able to use the CFS1 default objects included with CFS2.
7. I saw the cliffs mentioned in a recent thread on this forum. I tried the suggested scenery but no cliffs.
Maybe I missed something.
Be careful that mesh by different designers doesn't cause conflicts. It's best to settle on one even if it's not exactly what you want.
*PS. CFSIIEurope release 2 here.
