Flyboy,
At one time there was some effort to place Maskrider's CFS 2 scenery into FS 9, but I think the project died a quiet death.
CFS 2 scenery seems to work well in FS 8, but I think there is a scale issue with FS 9. Ian Elliott and Cees Donker have both made many airfields for both CFS 2 and FS 9. Perhaps they will have more insight into the problem.
