    Wow...I had an interesting offline experience today... In QMB, 3x veterans Zero 21s vs 4x Average P-400s. I came out second best!!

    True, I have been away for three years, but I did not think my skills deteriorated that much.

    I always read that the P-39 was woefully inferior to the Zero. However, the P-39 AI boomed and zoomed where I was unable to get within .5km!!

    I thought the Zero was faster and could climb better...

    After this experience, I downloaded IL2 Compare and found out that the Airacobra is faster on the deck,I didn't know that!

    Online, I can do better, but I must say, that I was quite perturbed by this experience.

    It seems the AI has improved in Boom and Zoom tactics since AEP

    If they had given the P-39 a real engine it could have been a 400 mph fighter. For the time it was extremely aerodynamically clean and pretty fast in its own right.

    mike you should be able to deal with cobras fairly easy, because of better maneuverability and better RoC especially on slow speed.

    Ais are tougher to shot down nowadays because you simply can't really catch up with them easily.

    It might have been just the fighter we needed to fight with in the early air battles against the Japanese bomber units pounding our bases in the Pacific and in Asia.

    From the article The Heart of the Cobra.

    Development of the Allison V-1710 Engine.

    The Allison V-1710 was America's only liquid-cooled engine to see wide use in the Second World War, powering tens of thousands of P-38, P-39, P-40, P-63 and other fighters. Although it proved to be a great engine, the Army's lack of interest and funding to develop better mechanical superchargers in the 1930s kept the engine from being developed to its full potential. The Allison was in many ways stronger and more rugged than the British Merlin, capable of withstanding operating speeds of 200-400 rpm higher than the Rolls-Royce design. One can only wonder what would have happened if Allison had adopted the Merlin's two-stage supercharger to the V-1710.

    However, the first two-stage Allison to incorporate an aftercooler was the V-1710-119 (-F32R) which powered North American's XP-51J to a speed of 471 mph at 27,400 feet in the spring of 1945.

    Having read Sakai's Book: Samurai as I am sure you guys have, that the Zero should have no trouble with a p-39.

    I found the Zero to be slow, to have very poor acceleration and a high energy loss in a zoom climb. None of these were characteristics of the Zero

    I hope its just my rusty flying skills and not a flaw in the Flight model of the Zero 21.

    It's not the plane flaw it's the Ai flaw.
    Any kind of even battle P-400 vs A6M ends up in Zeros favor.

    Yes, and that's a nice improvement. During old times you could fool a FW190 to turnfight with your il2. He'd turn till he was a sitting duck. Not anymore.
    Coming back to the zero, I think at the beginning of the war the japanese zeros were succesful partly because the americans did try to turn too much with the zeros. Then americans realised the mistake and change tactics...

    some thoughts about the performance of Zero 21, Wildcat and Airacobra

    http://www.j-aircraft.com/research/r...erformance.htm

    a bif proplem of the Airacobra in 1942 over NewGuinea and Guadalcanal was that the japanese Betties and thier Zero escort flew their attacks to high for the Airacobras engines.........
