The Miles M.30 X-Minor was an experimental aircraft, designed by Miles Aircraft to evaluate the characteristics of blended fuselage and wing intersections.

The small size of the X Minor made it impossible to follow the buried engine design exactly; the engines were too large and had to be mounted externally, resulting in an aircraft similar in layout but differing in aerodynamics.

The X Minor first flew in February 1942, providing Miles with useful data for several years.

A larger scale prototype of the X transport was planned but never built.
