[BF-109 F4]

I was curious and went to see the view objects menu and check what was the difference between the F4F-3 and the FM-2 Wildcats. Different and more powerful engine was maybe the only difference but the FM-2's armament kept my attention: 4x50cal. MG; 2x250lb bombs or 6x5-inch HVAR rockets?! I don't have that loadout! The loadout is equal for F4F-3 and FM-2!
The FM-2's was built for air-to-ground strike purpose, not fighter purpose like the F4F-3.
I heard it's not allowed to change the loadout of current planes but how about an exception for this one?

The FM-2 also had an enlarged tail, because of the increased torque of the new engine.

Yeah they mentioned that also in the description.
