They can have all the armour they want, as long as they can't utterly outfly a Fw190a8 in all but roll and dive acceleration,with or without internal bombload. they can have the 4*20mm as well.
That crew that can hit with 3,5-4g in turns makes captain America yellow.
Earlier, I wrote about an incident when I met an A20 over friendly territory, he first out turned me easy ( ok, maybe) then, still in hard turn shot off one of my rons, I dive and he he smoked my engine from straight 6 at 1k out, then he did a lazy turn and dropped his bombs on town.
wish I could use film but occasional stuttering happens when I turn film on.
Something is very wrong with that bird (or the A8).
