The Avis was a single-bay unstaggered biplane with full-span ailerons on both upper and lower wings.

It had a fixed landing gear with a tailskid and could be powered by a nose-mounted 32 hp Bristol Cherub II engine or a 35 hp Blackburne Thrush radial piston engine.

On the next day, it won the Grosvenor Cup at a speed of 65.87 mph.

[2] For the 1926 trials, it was re-engined with a 38 hp Blackburne Thrush, being eliminated after a forced landing.

In 1927, it was re-engined again with a Bristol Cherub I and passed into private ownership until it was scrapped in 1931.
