The Thruxton Jackaroo was a 1950s United Kingdom four-seat cabin biplane converted from a de Havilland Tiger Moth by Jackaroo Aircraft Limited at Thruxton Aerodrome and Rollason Aircraft and Engines Limited at Croydon Airport.

History

The Thruxton Jackaroo was designed as a four-seat cabin general purpose biplane, the original tandem two-seat Tiger Moth fuselage was widened to allow side-by-side seating for 4 people.[1] It was marketed as "the cheapest four-seat aircraft in the world".[2] The first conversion first flew on 2 March 1957.[3] Eighteen Tiger Moths were converted by Jackaroo Aircraft Limited between 1957 and 1959 and one aircraft was converted by Rollason's in 1960.[1] The aircraft could be fitted with an optional crop spraying gear.[4] One converted aircraft was further modified as a single-seat agricultural aircraft, but with little interest in the variant the aircraft was converted back to a Mk. 1.[1]
