When determining how good of a fighter something will be we need more information then maximum sustained turn rate, climb rate, and top speed. Stability is key in turn fights. If the japanese planes we have now are any indication of flap deployment then the 84 could be at least as weak as the 109s. Does anybody have figures for how well the 84 turns when going 150mph? 80mph? This will determine how beatable it is when it doesn't come in with an alt advantage, or its pilot makes a mistake.
