Development

[edit]

The Grasshopper was a conventional two-seat open-cockpit biplane, with a nose-mounted 100 hp (75 kW) Anzani engine. Only one aircraft was built, registered G-EAIN, which obtained its Certificate of Airworthiness in March 1920.[1] It passed through a number of private operators until 1929 when the Certificate was not renewed.[1] The last owner had been Constance Leathart.[2]
