The Yeoman Cropmaster was an Australian agricultural aircraft developed from the CAC Wackett trainer of World War II.
The Cropmaster and the CA-6 Wackett shared the same tubular steel fuselage frame
The first Cropmaster YA-1 conversions shared the wooden empennage and fabric-covered aft fuselage of the CA-6 Wackett
The Yeoman 175 was a one-off test-bed to check the characteristics of the new all-metal empennage
The proposed YA-1B Cropmaster featured a tricycle undercarriage, but was never produced
The CAC Wackett Trainer was the first aircraft type designed in-house by the Commonwealth Aircraft Corporation of Australia. The name was derived from its designer Lawrence Wackett. "In acknowledgement of the CAC Manager's enormous contribution, the RAAF were to call the aircraft the Wackett Trainer"
