Very nice looking build. I think (with no written documentation to back me up) that the airflow around the bomb part "wraps" a little to still get to the fincan, else it would be useless on the real bomb as well. Kind of like the laminar airflow over a wing, or around the relatively fat body of a scale V2. The fin assembly keeps the Cp behind the Cg for stability. On a real bomb, though, the Cg will be substantially forward, so this one will need a lot of nose weight. I suppose if you just dropped one of our rockets out of an airplane, it would line up with the relative wind in the direction of fall, just like a bomb would.
