[3] The Rhino was a single bay tractor triplane with ailerons fitted to all three sets of wings.

It was powered by a 230 hp (172 kW) BHP inline engine driving a two-bladed propeller, cooled by radiators each side of the fuselage.

[3][4][5] The first prototype made its maiden flight at Brooklands in October 1917, with initial testing showing it to be nose heavy and subject to engine overheating.

[4] The second prototype, which differed in having the primitive pillar mounting for the observer's gun replaced by a more modern scarff ring, joined it for official testing at Martlesham Heath in February and March 1918.

Performance was unimpressive, with the aircraft having a poor ceiling and low speed, and it was rejected as a service type.
