One production aircraft was modified for use as an advanced trainer: after evaluation by the Central Flying School at Upavon this was ordered by the RAF, the production aircraft differing from the prototype in having slightly swept wings and an enlarged fin to improve spin recovery characteristics.
The first aircraft to be delivered to the Royal Air Force entered service with 3 Squadron in May 1925 at RAF Upavon.
The RAF Air Cadets, known as the Air Training Corps, used static winch-launched gliders of No. 622 Volunteer Gliding Squadron (VGS), along with the Army Gliding Association (AGA) Wyvern Gliding Club (which used self-propelled, winch-launched, and aero-towed gliders).
