Good airfiles for the default DC-3?

Hi all! Which in your opinion are the most realistic airfiles for the default FS9 DC-3, and where can they be downloaded? I've tried various, but to my (undoubtedly non-professional, it has to be said) experience all of them have had a problem or two, such as the bird levelling itself out on coordinated turns, funny stall speeds / characteristics, etc. I've heard that the MAAM C-47 is a great one FM-wise, but how about the default DC-3? Has anyone done a set of good airfiles for it? Thanks for any pointers you'd care to share with me :)
