There was one version of the Buffalo with stellar performance, the F2A-2, with a good engine, 4 .50's and 160 gal. of fuel. 344 mph. All others had very poor criminally rebuilt engines, or too much ammunition, or 240 gal. of fuel. True, the good one lacked armor and self-sealing tanks, but it performed well. If it had a smaller tank, self-sealing, and armor plate, there might have been a contender, but there wasn't. That would be the one with fans. The F2A-2 didn't enter combat.
