thickosehaskel has a nice selection of Mig-3s in the Archives. They are CFS2 models, but they work well in FS2004, look nice, and I have found that most of thicko's planes fly well in FS2004...a few need a bit of FDE tweaking, but most are usable from the get go. You will need to tweak the config file entries for the aircraft, adding in the lines for manufacture, type and variant...add some FS9 lights and such. Thicko produced a really nice selection of war birds that are quite enjoyable in FS9...lots of Russian stuff.
