Pros and cons

Pros:

  • Very agile
  • Deadly quad autocannon armament
  • Like the other two KI-84s, this one also has an excellent performance between 4000m and 6000m (AB)
  • Set weapon convergence at 800m, align your wings with your enemies and watch them explode through your 30mm cannons (AB)
  • Starts stalling at 180 km/h and can maintain altitude with takeoff flaps (AB)
  • With its strong engine (1960 hp in AB) this plane excels at boom and zoom attacks
  • Combat flaps can be used at 450 km/h IAS, without them getting ripped off

Cons:

  • Limited cannon ammo
  • Fights post war props and jets often
  • The velocity/ballistics of the cannons (Ho-5 and Ho-155) differs a lot, making aiming difficult if you haven't bound separate keys for small and large caliber guns
