The Mitsubishi Ki-57 Type 100 (Allied code name "Topsy") was the main troop transport of the Imperial Japanese Army and saw extensive duties in that role from the beginning to the end of World War II. It was also used in limited numbers by the Imperial Japanese Navy under the designation L4M1 and was also the main aircraft for Japan Airlines (Nippon Koku K.K.).
The Ki-57 was developed out of Japan Airlines need for an aircraft to be its main courier and JAL was impressed with the performance and range of the Ki-21 bomber and wanted to develop a civilian version of the Ki-21. The IJA took notice of the development of this new civilian plane and took over the project and issued specifications that would satisfy both military and civilian requirements. The Ki-57 retained the wing, cockpit, engine, tail of the Ki-21 but featured a different fuselage that could accomodate 11 passengers in addition to the 4 crew. From 1940 until 1945, over 500 Ki-57s were built and served as paratroop and troop carriers as well as logistical and supply transports.

How would this plane do in Aces High?
Basically, it would be a smaller but little faster version of the C-47. Even though in real life the Ki-57 was only able to carry 11 troops, this isn't an issue in Aces High as only 10 troops are available per transport. Even it's limited real life cargo capacity isn't a factor in Aces High so there is really no real life mitigating factors that would proclude the Ki-57 from being considered a viable additional as a 2nd transport plane into Aces High. It will also be of benefit to the AvA weekly scenarios as well as the FSO and main scenarios.
