lol, Never liked the location of that gun, we talked about that on the other thread. They gave it a tiny degree of movement despite it's precarious location (which is crazy), considering it's risky, even without any independent movement of it's own. If the chopper has to turn and point it's nose at the target to aim and if it's firing rapidly and turning vigorously to the right at the same time, it's already risking coming close to the line of fire. Add a small degree of movement to the gun on top of that (and the tapered groove in the body) and that's the result.
That's a limitation the Ka-52 has, unfortunately. They needed the radome space for the radar, the bottom of the radome for the EOS-52 and the gun was left out to find another location. They'll have to extend it further out of the body or push it forward more and remove any independent movement.
