Not in my experience. Sure, 11 kills can be fairly easy to get, but even then, it only takes 2 missiles to take a chopper down, and using cold blooded, it becomes much harder for people to see you.
Of course, if you're not using Cold Blooded, you can expect to get killed by killstreaks quite more often, but that's up to the player's class, imo.
