Ink, I know you are a big ki84 fan, but much of your praises of the plane are exaggerated. I fought countless ki84s in the MA and remain unimpressed. In a P47, with a few kft under me, the ki84 is completely avoidable even when it has the advantage. Above 10,000 feet the P47D is faster and even climbs about the same on WEP. Above 20,000 where P47s were supposed to fight, the KI84 is a joke. Against the P47M the ki is outclassed unless the fight is turning circle a at under 200 mph... But then a zero is even better and that does not make it a great fighter.
The best turn/stall fights are done with planes that were not made for it. Take a B25 or a B26 in fighter mode (no drones, using the fixed guns) and you'll see.
