Hi all. I have installed PMDG's 737NG in FSX by transferring all aircraft files to simobjects folder. Aircraft looks beautiful against FSX scenery, and everything works well except for the fatal "CG not within tolerance, aircraft unflyable", which indeed makes vertical control impossible. I have tried to use the Load Manager to correct this, but it only works in FS9.Given that his appears to be the only problem in using the excellent 737NG into FSX until a new version is available, does anybody know how to solve this problem?Appreciate anybody's suggestions.Thierry

To my limited knowlege, no one has successfully ported 737NG to FSX.

The FS2002/FS9 NG is absolutely not compatible with FSX - there's nothing you can do that will make it so. Please just wait for the new one we're making...

Well, for a product that is "absolutely not compatible", it behaves really well in FSX--except of course that it tends to crash every time... Thanks for the replies.
