Amazing what dweebs will do to get cannon in their birds to make them UeberPlanes. Find the *least* representative version of the plane in some obscure page of some obscure history and viola: instant mandate for the cannoned Corsair. It worked in Brand W, for a time, and flushed out a whole sewer full of sudden Corsair lovers with 20mm envy.
Look; most of those 4-cannon Corsairs were in crates on ships on the way to the front when the bombs were dropped and the war ended. The rest prolly served ground pounding Okinawa or some such. They weren't clearing the Slot or taking Rabaul, or taking part in the Marianas Turkey Shoot and other defining moments of the war like the Corsair you *really* profess to love; that being the 6 x.50 version.
If you want cannon, fly a cannon-armed plane. A *representative* one.

Just stirring the pot a little, and lamenting "modeling favoritism" things like the fact that we've never seen a FW190F (with the 4 x 100kg bombs in addition to the centerline 500 lber.) in *any* game, to counteract all those US planes with huge payloads and rocket loadouts.....<g,d,r>
