Greetings,
firstly, thanks for bringing a Ki-45 into a game. Finally a big hole of pacific theater is filled! Plane appears to be modelled beautifully and accurately, thanks.
The plane however appears to have inaccurate armament. The plane in the sim appears to be equipped with Ho-5 20 mm cannon (in all versions where it carried a 20 mm weapon, save the Kai Tei with upwards firing cannons). In reality however the plane carried a Ho-3 20 mm cannon, which is far more powerful. (Sources: Francillion,

Ho-5 round: 20x94, 720 m/s, 79 g (HE round)
Ho-3 round: 20x125, 820 m/s, 127 g (HE round)
It would be nice this cannon gets modelled and retrofitted onto a Ki-45.
Best regards!
