The Zero was undoubtedly better than the P-26, yet the latter had managed kills on the former.
There was only one engagement between P-26s and A6Ms, on 12 December 1941 near Batangas - seven 6th PS P-26s versus nine 3rd Kokutai A6Ms. When the smoke settled, the score was 5-0 in favour of the Japanese.I don't disagree, similar things happened pretty much everywhere, though it depends on the context, in this story's case, a 1v1 where the F1M pilot only has to focus on the SOC so the chances the SOC pilot has to gain an advantage are depressingly low to nonexistent.
In a P-26 I think you would have a similar sustained turn speed as with a A6M2 (as the zero loses its maneuverability at lower speeds) which shouldn't be the case with the SOC-3.
P-36s versus the A6M, sure. P-26s, no contest. Way too big a tech gap. The Zero's maneuverability was finest at low speeds. I would realistically expect the F1M to trounce the SOC-3. Evidence shows that F1M pilots frequently handled their planes as aggressively as one would handle single seat fighters. Not sure if one could say much the same of SOC-3 pilots.
