The FAA pre-cover inspection of the first wing of his prototype
Midget Mustang was January, 1953. Bob built his prototype version of the Midget, N15J, and first flew it on September 9, 1959. In 1959 he purchased the rights to the Midget Mustang and began to sell prints for the M-I. In
San Antonio, Texas, he built six Midget Mustang aircraft. In 1963 he began work on a two place design based on the Midget Mustang. In 1965 the first ever Mustang II (N1117M) was brought to the EAA convention at Rockford (by trailer) and in 1966 the prototype was flown to the convention. For the next 26 years Bushby Aeronautics sold plans and kits for the Mustang II. In March, 1992 Mustang Aeronautics, Inc. acquired the design rights from Robert Bushby for both the Midget Mustang and Mustang II aircraft. At the Homebuilder's Dinner at
EAA AirVenture Oshkosh 2016, Bob received special recognition from the EAA commemorating 50 successful years of his Mustang II design. ==Awards==
