Well, I must say that after the v 1.1 patch (that includes flap patch by Gerd) the flight characteristics definately improved. The plane definately began to turn and climb better.
However, still not as good as Ki-84 and J2M5. Try A7M2 against 1943 Bf-109G-6 (without MW-50!) and you'll instantly feel and see what I mean. In contrast, with Ki-84 and J2M3/5 I just tare these Bf-109G-6s and even FW-190A-5/6 apart. The latter are no match for the former, either in climb and acceleration rates, not to mention the agility. As for the A7M2, it is fairly fast, accelerates modestly well, but again not even close to J2M3/5. I had a hard time outmaneuvering even the Hellcats, which were supposedly outdated by 1944, when exposed to the newer breed of Japanese fighters. It just doesn't turn as easily as the Ki-84 and the J2M3/5, despite having a much greater wing area. In my view, this is something that needs to be refined in the patches to come.
The external model still needs some refinement, but I think it is a matter of time.
Overall, the A7M2 definately is another jewel of this wonderful game, a jewel so much craved throughout many years.
Many thanks to all those who contributed to the creation of this great mod!!!
