Su-33: More than six skins at the same time?

With Su-25T I can edit meinit.xml and its .skins file to add a new skin slot to the list.

For the Su-33 there doesn't exist a .skins file but maybe there is another way I can add a new skin slot? (if I only edit meinit.xml there appears a new slot but if I choose this Skin Slot the plane appears without a skin as expected)

Sorry! They cannot add a new Skin for the Su-33 or other. This is hardcored! ;)

There must be a way because it is possible for the Su-25T, Su-39 and a custom F-15C model (as I can remember) as well.

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.

Okay, thx for the clarification! So the only chance would be to make a new Su-33 model which uses skins files. :/

Yup.
