A3 CAC Wackett
CAC's first in-house design resulted from a 1938 decision to obtain a low-wing monoplane trainer because that was the configuration most future RAAF aircraft would have. CAC was awarded a contract to build two CA-2 prototypes in October 1938, powered by 130hp DH Gypsy Major engines. The first aircraft made its maiden flight in October 1939, and the second was handed over to the RAAF in March 1940. Both aircraft were later re-engined with the 200hp Gypsy Six.
Production aircraft were designated CA-6 and, due to the unavailability of Gypsy engines, were fitted with 175hp Warner Scarab radials. This engine was tested in one of the prototypes during 1940 and found to be satisfactory. CA-6 deliveries began in March 1941 and were completed by April 1942. Serial numbers were A3-1 to A3-200. The two CA-2 prototypes were re-serialed A3-1001 and 1002 to avoid duplication. The type proved to be a successful training aircraft, flying with many Empire Air Training Scheme Units throughout Australia and ending RAAF service in 1946.
