The T.31 was a tandem two-seat development of the T.8 Tutor (RAF Cadet TX.2). The fuselage was based on that of the T.29 Motor Tutor, increased in length and widened slightly; the wings and tail were unchanged. A single T.31A prototype was flown in 1949, followed by the production T.31B, with spoilers and a small additional wing bracing strut.
Model from Michel Delrieu's plan published in RCM in October 1990.
