Almost all aces in AC5 have OADF markings when you fly them. This might even apply to gameplay, though I'm less positive. There's no need to add Replicator to the OADF or Twicedead to the YAF.

(FYI, it's not impossible for Twicedead to actually be Yuktobanian - the Vladimir Mountains were, in fact, in Yuktobanian territory. :P)
