Why is this plane such a dog?  I'm referring to it's E bleed in a climb or turn.  If I understand, it's about the same size, weight, and horsepower as a F4U-1 but it's E bleed is way worse.  What accounts for this?  Is it historically accurate?  Is it the thick wing, or was the airfoil less than ideal for a fighter?
I figure some of you RAF types must know the score, please shed some light on it for me.
