08/31/2012. Remarks by Walter van Tilborg: "The RA-14/RA-17 series of light two-seat sport aircraft was designed by Roger Adam and built by Établissements aéronautiques Roger Adam.
RA-14 Loisirs: The RA-14 was mainly intended for construction by amateur builders and aero clubs, using Adam-supplied parts and components. The RA-14 had a fabric covered fuselage and wings and was built in several variants, with engines in the 65-90 hp power range. The RA-14 made the first flight on March 16, 1946 and this aircraft was powered by a 40 hp Train engine. The type was popular in the immediate post-war years and an estimated 29 were built. In 1957 Maranda Aircraft in Canada acquired the marketing rights for the RA-14 and also developed several improved versions. Another homebuilt variant was available from Falconar, also in Canada.
RA-14A Loisirs: One example with unknown modifications.
RA-14S Loisirs: One example built as new aircraft by Adam, featuring a plywood covered fuselage and several other features of the RA-15 model. This variant was not proceeded with.
RA-15 Major: The RA- was externally and dimensionally similar to the RA-14, but had a plywood covered fuselage, a much larger vertical tail and also featured improved systems. The first example made its maiden flight on April 13, 1947. Engine in the RA-15 was a 75 hp Régnier 4D-2. Only two were built.
