If the only reason to add MG81 is that the original gun "sucks" then while we're at it we might add a rocket engine too because the one the plane has now sucks. The plane modeled is the A-3 and MG15 is what it had historically. If someone is to make an A-5 with all the differences between the two versions then MG81 would be in order - otherwise not.
