Derived from the Elephant via a single-bay experimental variant of the earlier design by A A Fletcher, the R.G. bore a close resemblance to its predecessor and was initially flown late in 1916 with a 190 hp Rolls-Royce Falcon I 12-cylinder water-cooled engine. Armament comprised a fixed 0303-in (7,7-mm) Vickers gun on the port upper longeron, outside the cabane struts, and a Lewis gun on the starboard side of the cockpit. After official trials in February 1917, the R.G. was revised in a number of respects. The cockpit was moved aft and the centre section cut-out was enlarged, the span of the lower wing was reduced, the rear top decking was raised, armament was revised and consisted of two 0303-in (7,7-mm) Vickers guns immediately in front of the cockpit, and a 275 hp Falcon III engine was fitted. In this form, the R.G. had, according to the official report, a “performance ... far and away better than any other machine manufactured”. However, development was discontinued in favour of the superior F.3.
