Stoney you bring up another issue...
HTC doesn't model "what a plane COULD do"... they model "what a plane did do" --- You could strap 5 20mm cannons on the nose of a P-38, there was room, but it was never flown this way.
You COULD put 20mm cannons on an F6F-5P, but there's no photo evidence that this ever happened.
You COULD do a lot of things, but HTC models the field practices. The 47M was technically a "D" frame and wing, so it could theoretically carry 2500lbs of bombs, 10 rockets, and 400rpg overload ammo for heavy ground attack and strafing.... However, If this plane only ever saw service as a fighter, with no ground ord, no rocket rails, etc, HTC will not model them as an option.
So finding out what weapons load it flew with is in the best interest of HTC.
Otherwise, the spit5 "COULD" have flown with 120 rpg for the cannons, but for the model we have in-game, it never did. Same for this model of P-47. What it did, and what it could do, are 2 different things.
