N1K2-J: 8800lbs, 253ft^2, 1990HP. Wings have automatic manouevering flaps.
Me 109F-4: 6000lbs, 173ft^2, 1300HP. Wings have manual split flaps.
They are close; the N1K2-J turns a smaller radius, possibly a little faster(time). Fuel load is going to be a big factor.
He's right though, one notch of flaps in the Franz cuts turn radius by about 10%, without affecting turn rate much. Problem is they don't extend until you get below 175mph IAS.
