Depends how you consider out-turn, Shark. Stall speed turning, where radius is important, then the Hurri II can out-turn it. At speed, or where the vertical is more in play, then the Spit's vastly superior climb rate horsepower would likely come into play. There are some other planes that can out-turn the Spit too, or are very close to call. N1K, FM2, F4F, Zero (easy)...
The original post though was a troll... AronL was just trying to see if people would respond to a statement that wasn't true.
