Hi Widewing,
>I agree. It took a big hit in maneuverability. Was a time when it could handle the P-40E in a stall fight... No longer, the P-40 eats it alive.
Surprising! What's the boost of that P-40E? I've made a quick estimate for the Ki-61, using DB601A-1 data (1020 HP max), compared to a thorough P-40E analysis (1210 HP max at 44" Hg/ 3000 rpm).
My results suggest a great advantage for the Ki-61 in most respects, particularly turn. As the P-40E is heavier by a ton, that seems realistic to me :-)
