Design and development

An enlarged version of the earlier Maeda Ku-1 glider, it was developed during 1942. The use of a twin boom design allowed for a large square cargo door, which meant that the aircraft was capable of carrying either 32 soldiers, 7600 kg of cargo or even a light tank. +more It required a powerful towing aircraft, either the Nakajima Ki-49 or the Mitsubishi Ki-67, which were in short supply. As a result, the aircraft were modified by fitting them with engines, which were designated the Ki-105 Otori (鳳 "Phoenix"). Intended for use as fuel transports, only nine, of 300 ordered, were produced before development priorities were shifted elsewhere.
