Get close, and fire, ammo management is the key those 20mm Ho-5 are awsome guns, but u nead to manage the ammo it goes very fast, the rof is WAY high, use the 12.7's to find your target and make the commitment with the 20mm, get close so you dont miss.( I have had 12 kill sorties Vulching so I know it is capable of great things if you use the ammo corectly, that was all cannon btw no 12.7) Also always fire the cannon sepretly of the MG that way you know wher they are going, and when and whear you get cannon hits.
I fly it with 50% fuel and the drop tanks, any US plane is easy meat if they want to turn, the Brit wounder turners are a different mater.
It is slow you can not run away, but the babes love the paint job:)
I love it, the 205 and the Ki 61 are my favorate fighters. For now at least:) ( plese dont tell my Zero I said that:) )
