"The Frank (Ki-84)...would outclimb any Allied fighter (including the P-51D), and would out-turn all of them (including the Spitfire)."
--Edward Sims, Fighter Tactics & Strategy, 1914-1970
But wait, there's more....Twin 20mm cannon! This plane will be awesome -- more effective in the MA than the P-51D and very possibly the La-7, both of which many people think should be perked. [Kweassa's perk plan seems to have gotten the most support. Check it out.] If so, should the Ki-84 be perked, too? But that would be politically impossible, I mean perk the new fighter plane we've all been waiting for? No way will that happen. So prepare for a Ki-84 scourage, the way the Fokker E. III dominated the Western Front during 1915. Well, not quite that bad, but you get the idea; it will be a very popular and superior plane.
Nevertheless, I predict that after a few months we'll see the "Hayate" [pron. hah'-yah-tay], aka "Frank" get perked, I hope along with the P-51D, La-7, Fw-190D-9, Bf-109G-10, Yak-9U, and maybe the Typhoon. By perking them all at the same time, we'll get the whining over with in one dose, and avoid charges that "you're just picking on my favorite plane!"
