Morton/Simonu,
There is/may be a way to convert pure native FSX ac.
Using Bill 'Lionheart' Ortis conversion technique which basically removes the FS9 polygon limit from the compilation process, along with a large number of processes and tweaks, you can convert from native FSX to Fs9. (I have his pdf guide if anyone wants it)
Now once a functioning Fs9 model it may/should be possible to convert to CFS2?
Something to fiddle with during the long winter months..............
I know this is a very nice freebie, but a great and easy conversion is ol' Alphasim's DH100Vampire, if you haven't that already.
Cheers Shessi
