Yeah I think you are really worried about nothing.  Yes with an ARF ya want to check the factory glue job but that plane looks plenty strong to me, it IS a 3D plane after all, it doesn't look any different than others I have seen.  Carbon fiber blocks 2.4 gig signals so if you add a bunch of it then you can think about where you are going to mount the RX so the signal doesn't get shadowed.
