There was also a Ki.61-II later in the war, in the sim we have the Ki.61-I versions. The Ki.61-II had several improvements/changes- from memory, some dimensional changes and a more powerful engine, the Ha-140 of 1,400 hp. Unfortunately for Kawasaki, the Ha-140 suffered from hopeless reliability and furthermore the plant producing the engine was bombed.......... leaving Kawasaki with an increasing number of desperately needed airframes without engines. Enter the Ki.100, a Ki.61-II airframe with a Mitsubishi radial replacing the inline Ha-140- surely one of the most remarkable lashups ever and definitely one of the most successful.
Here's a thought for the modding geniuses: replace the Ki.100's radial with the Ki.61's inline engine to create the Ki.61-II. After all, it's only the reverse process of what Kawasaki originally did!
