Me 110. Very Hard to Destroy.

That is probably regarding the MG151 which was a lot better (Because they refer to 4 engined bomber)

Still the MGFF was a good weapon IRL, if you hit a radiator: it's gone, you hit the cockpit, pilot gone. And ripping off fuselage is not just a mere 'flesh' wound it unbalances the whole plane, making it slower and harder to control, that happens when only 1 round hits, now you've got 2 canons firing at 520 rmp, that should not be doing 'light' damage.
