The design of the K10W (known as the "Oak" to the allies) was only superficially similar to the Yale in that whereas the North American aircraft was steel tube construction covered by metal or fabric, the K10W was stressed skin. Coupled to it having a smaller wing span and smaller chord wings with a longer fuselage and higher aspect tail plane, this Nakajima Kotobuki powered trainer was not liked by it's crews and production ceased after 176 including 17 prototypes.
