The Hemly Aerogypt was a British four-seat cabin monoplane designed and built by Egyptian S Helmy at Heston Aerodrome in 1938. The Aerogypt I was a low-wing cantilever monoplane powered initially by three 22hp (16kW) Douglas Sprite engines. The aircraft had an upward hinged roof which acted as a landing flap. Registered G-AFFG it first flew in 1939 and later had the hinged roof removed and was re-designated the Aerogypt II, another modification added end plates to the horizontal tail surfaces and was re-designated the Aerogypt III and last flown in that configuration in September 1940.
In 1943 the aircraft was modified as the Aerogypt IV with a tricycle landing gear and two 65hp (48kW) Continental A65 engines. It was damaged beyond repair after a landing accident in November 1946 at RAF Northolt when it was dropped by the recovery crane.
