Percival Mew Gull: a short, easy version

What it is
- The Percival Mew Gull is a British racing airplane from the 1930s. It’s a small, single-seat, low-wing monoplane with wooden construction. Most examples were powered by a 200 hp de Havilland Gipsy Six engine. It was designed by Edgar Percival at the Percival Aircraft Company as a smaller, faster racer building on the Gull line.

Design and development in brief
- The Mew Gull started as the E1 design, then became the E2 with a new wing and longer fuselage. A version with a new wing and longer body was later called the E2H, and finally the E3H. The design kept a fixed main undercarriage and a tailskid. Small trailing-edge flaps were added, but they were not very effective.
- The project involved significant work by designer Arthur Bage. The Mew Gull family remained the core racing line from 1934 to 1938, with five or six aircraft built in total.

Key aircraft and what happened to them
- G-ACND (prototype): First flew in March 1934. Initially used a Napier Javelin engine, then swapped to a 200 hp de Havilland Gipsy Six. It helped establish the Mew Gull’s racing potential.
- G-AEKL: The first E2H and Edgar Percival’s personal plane. Won the 1937 Newcastle Race and the 1937 King’s Cup. In 1938, it finished 2nd in the King’s Cup; the race was won by G-AEXF.
- G-AEXF (ZS-AHM’s later form): Raced by Alex Henshaw and later by others; won the 1938 King’s Cup with a speed of about 236 mph. Henshaw’s Cape flight (rested on 1,046 miles out-and-back) in 1939 set a Cape class record that stood for decades. The aircraft was later preserved and rebuilt several times, and today parts survive in replicas and displays.
- G-AFAA (E3H): A single E.3H built for Edgar Percival; it finished 3rd in the 1937 King’s Cup. It was damaged during the war and eventually burned along with earlier airframes after World War II.
- G-AEMO/ZS-AHO: An E2H built for the Schlesinger Race. It crashed in Southern Rhodesia after a forced landing; the wreckage remained for years.
- ZS-AHM/G-AEXF: Original race aircraft that was later heavily modified and then raced as G-AEXF. It had a long racing career, including the Cape flight era, and was rebuilt several times before ending up in museum collections.

Racing achievements and history
- In the late 1930s, Mew Gulls dominated UK air racing and long-distance events, setting some of the era’s fastest times.
- 1934 King’s Cup: The prototype in its early configuration reached about 191 mph but did not win.
- 1937 King’s Cup: G-AEKL won the race (with Charles Gardner later marking a notable triumph in its blue “house colours”).
- 1938 King’s Cup: G-AEXF (flying with Henshaw) won the race at around 236 mph, setting a class speed record that stood for many years.
- 1939 Cape flight: Henshaw flew G-AEXF from Gravesend to Wingfield and back, covering the 6,377 miles in about 39 hours. This established a remarkable long-distance performance for the era.
- World War II halted civilian flying, ending the peak racing era for the Mew Gull.

Replicas and displays
- G-HEKL is a UK-registered replica of a Mew Gull that is currently airworthy in Britain.
- A static replica of G-AEXF is on display at the RAF Museum Hendon to represent the Cape-record version of the aircraft.
- The real Mew Gull lineage has inspired ongoing restoration and display efforts, connecting modern visitors with the golden age of air racing.
