Percival Vega Gull was a British tourist, training and liaison plane with a fixed undercarriage, which was flown in 1935, and during its production (which lasted in 1935-1939), about 90 machines of this type were built. The plane, in its basic version, was 7.77 meters long with a wingspan of 12 meters. The drive was provided by a single de Havilland Gipsy Six engine with a maximum power of 205 HP. The maximum speed was 280 km / h, with a climb speed of 5.2 m / s. The machine did not have on-board weapons.
The Percival Vega Gull was originally developed for the civilian market as a light tourist aircraft, an evolutionary development of the Percival Gull. Compared to its predecessor, the new plane has been lengthened and its wingspan has also increased. A fourth seat in the pilot and passenger cabin was also added, and the rudder system was modernized. Despite relatively minor changes, it was possible to significantly increase the lifting capacity and flight range. Aircraft of this type were also exported to several countries of the British Commonwealth, including Australia and New Zealand. After the outbreak of World War II, many Percival Vega Gull machines were commandeered by the RAF and directed to school and training purposes, where they did not work too badly. The Vega Gull model was replaced by its successor - the Percival Proctor machine.
Percival Proctor was a British training and liaison plane in the low wing configuration, which was flown in 1939, and in the course of its production (which lasted in 1939-1945) about 1,150 machines of this type were created. The aircraft, in the Proctor Mark IV version, was 8.59 meters long with a wingspan of 12 meters. The drive was provided by a single de Havilland Gipsy Queen II engine with a maximum power of 210 HP. The maximum speed was 253 km / h, with a climb speed of 3.6 m / s / The machine had no on-board armament.
Percival Proctor was constructed in response to the demand submitted by the British Air Ministry in the late 1930s for a new training plane for training pilots and navigators. The new machine was created as a development of the Vega Gull model, also from the Percival Aircraft Company. Ultimately, a successful plane was created, relatively easy to pilot, cheap to operate and generally of a sufficiently solid structure. In the course of serial production, several development versions were created, including: Proctor Mark I (basic version produced in serine), Proctor Mark II (aircraft dedicated to training navigators), Proctor Mark III (liaison version) or Proctor Mark IV (training version with 4 -person crew cabin). Aircraft of this type were used on a large scale during World War II to train RAF pilots, and after 1945 a large number of them entered the civilian market.
