FM-2 isn't close to a Brewster. Nor is a Hurricane IIC close to the Hurricane IIB's which the finns faced. I truly hope people here can figure out the difference between 12x.303s or 2xberezins/2xShwaks and 4 Hispanos.
Also, at least in the lower alts Brewsters were actually faster than the Hurricane Mk.II which surface quality deteoriated rather quickly in harsh front conditions. Brewsters' manufacture quality was (considering the Corsair-epsode) surprisingly good and they retained their performance very well. Granted, in the Lappland War which was fought against the germans during the spring of '45 they started to be worn out after close to FOUR years of combat flying and 1 year of peace time service. Few of them even served couple years after the war.
I don't think FM-2 is a good sub for the Brewster. I also do think that when the plane set just isn't there an RPS might not be such a good idea. But whining about the horrible unjustice which the FM-2 supposedly represents almost leaves me speechless. FM-2/Hurri2C is a very close match up.
It would be awesome to have a real Brewster in the game with Ratas and Tchaikas to fly against. Just the maneuverability of those planes would send the fan factor through the roof!
