I think that the inclusion of most IJAAF types is justified, except for a few 1945-46 ones, that might not have seen successful production, but that is a common problem for IJAAF/IJNAF. Unless we postulate alt-historical changes to production, Oscar is, maybe, the only plane worth changing. In RL all Oscars deployed in combat had one rifle-calibre MG replaced with a 12.7 MG (probably only communication aircraft and such had 2x7.7). On the other hand, that was a standard armament until late 1943. But in-game Oscar's firepower is already well below its historical capabilities. So I didn't do anything with them. If you want to reduce the number of models, we can merge Ia and Ib. Also, Ki-43-IV actually carried the same Mitsubishi Ha-33 engine that our late-war Zeros do! If you want, I can do the change and accelerate it a bit, to reflect earlier overall adoption of this engine as the standard and its faster development, as I did with other planes that use it.
