If it has the 2 .mdl files it is native is my understanding, if not it is a FS9 craft converted (should have said ported) to use in FSX.
Not necessarily..many FSX native aircraft,both freeware and payware, have been released without a VC model and yet are "Native". For those that run DX10 mode generally only FSX native aircraft can be used without graphics issues (yes I know that some portovers might display okay ,but they are few and far between).
