I can answer that if XS Hster doesn't mind me butting in.
Yes the Revell release does come with yellow emblem as separate decals.
And having built both the Mobius and Revell Mk2's, I have to say that the Revell decals are vastly superior. The Mobius ones were semi transparent and disappeared if applied over painted wing markings.
Fantastic build by the way, I'm looking forward to seeing the finished ship.
