I dont have figures for the radious of turn for the either the Sppitfire, ir the Seafire. Do you have them,so that we can compare. I assume your claim "the Spit can outmanouvre the zero at low speeds is a claim that they can ou turn the zero....seems a bit unbelivable, but would like to see your figures first.
If you are referring to dive speeds, roll rate (above 300 knots) and combat after October 1942, when new tactics against the zero had been worked out, almost certainly you are correct. But difficult to accept if the combat is early 1942, using the tactics of the time
Before I make any conclusions, however, would like to see your source, and the figures you have
