[6][9] A second aircraft was retained by Sopwith as a demonstrator, being used to set a number of British altitude records between June and July 1913.

A further two tractor biplanes were built for the RNAS, being delivered in August and September 1913, with the original hybrid being rebuilt to a similar standard.

Following tests of a Tractor Biplane fitted with ailerons instead of wing warping for lateral control,[6][10] a further nine aircraft were ordered for the Royal Flying Corps (RFC) in September 1913.

[11] The RFC received its Three-seaters between November 1913 and March 1914, with the first example being tested to destruction in the Royal Aircraft Factory at Farnborough, where it was determined that the structural strength was inadequate.

5 Squadron left its remaining Tractor Biplanes in England when it deployed to France in August 1914, these being briefly used as trainers at the Central Flying School.
