FS2004/FSX Miles M13 Hobby. A racing aircraft designed by F.G. Miles for the 1937 Kings Cup Air Race in the U.K. Problems with the retractable undercarriage design denied him the chance to compete, but in 1938 the aircraft was sold to the RAE at Farnborough for comparison trials between the 24 foot diameter wind tunnel and free flight.
