On display at RAFM Cosford. Built to Air Ministry Specification A.4/45, the Pioneer first flew on Nov. 5, 1947. The underpowered 240 hp Gipsy Queen 32 was replaced by the 570 hp Leonides radial engine. The fully loaded Pioneer's STOL performance of 68m to take off and 60m to land allowed the RAF to operate from jungle airstrips in Malaysia and Borneo. A total of 59 were built, also operated by Royal Ceylon Air Force, Royal Malayan Air Force and the Sultanate of Muscat and Oman Air Force (SMOAF) as its first aircraft.
