changing the skin of an aircraft won't change its nationality. Eg, a russian spit can have an RAF skin, but will still be russian, and so too will its section.

In the advanced settings in the QMB, change your nationality to whichever nation you want, eg RAF, USSR, or USMC etc. Your section, ie the 3 other planes who fly in formation with you, will change to that nationality.

Hope this helps!
