Stock carbon tubes eh? Interesting...! As far as replacing the tail boom (I have plastic blades), I've had one frame that was runied because it wouldn't come out. The other one, fine. When I install a new tail boom on this frame, I use 1/2 drop of locktite plastic super glue. It will break loose once in a while and I'll have to re-glue it but I'm not wrecking frames if I have a boom strike. The one thing you have to remember is that the original hole for the tail boom is a METRIC hole requiring a metric drill bit. A reamer for that size hole would be real good to have.
