No because those aircraft, when FC came out, were redone to allow a .skins file (along with a .lom file) to be used. Face it, the Su-33 really doesn't have much use, so ED probably figured "okay, we'll just not utilize the .skins format with this aircraft." Yes it's one of the best planes in the flyables section, but in regards to the other aircraft, it's not as popular. However, when BS comes out in the next millenium, all the aircraft should have a .skins file due to the constant nagging (to which I agree with) of the hoi polloi.
