Thank you shed some light on this dark page of history Ki-43, because in English-language sources probably crept mistake and they stated that Ki-43-III Otsu has Ha-112-II engine.
One more question. AeroDetail 29 mentions performance degradation of Ki-43-III Otsu (compared with Ki-43-III Ko I think). There is a chance that Otsu has Ha-115-II engine (not Ha-112-II that points western sources), because FAoW 65 and AeroDetail 29 not talk about engine model for Ki-43-III...
This screenshot from this.
I believe 7.0G is safe loading factor and 1.8 is safety factor. The P-51D structural load limit is +8G and -4G (plus a standard safety factor of 1.5).
Is it possible that Zero was more durable than the Mustang aircraft (7*1.8=12.6>12=8*1.5)?
Does anyone have any information on ammunition for the MG-FF (not MG-FF/M) cannon. I know MG-FF used 134g projectile. And i found this document. But i need more info about projectiles (scheme, filling weight, dimesions).
