The first flight had taken place with the spinner unpainted: it had subsequently been painted, and the additional weight of the paint had caused the failure. A third flight, without any spinner, revealed that there was still a problem with the ailerons. An attempt to rectify this was made by fitting a device which produced a small control surface movement for small movements of the joystick, with the rate of control surface displacement progressively increasing as stick displacement was increased. This device, which used a cam on the bottom of the joystick to displace a pair of rollers connected to the ailerons, worked on the ground but under flight loads the rollers were pulled out of contact with the cam, resulting in loss of lateral control. Uwins made yet another wide circuit in the aircraft and again managed a safe landing. For the next flight the cam device was removed and the control issue addressed by reducing the area of the ailerons to around 40% of their original area. At the same time a new spinner was fitted, this being designed to remain static. Three further flights were made, during the last two of which the undercarriage was successfully operated. Although the aircraft had been entered for the 1922 Coupe Deutsch de la Meurthe competition, and was allocated the racing number "10" which was painted on the tail, it was not in a fit condition to compete, and although it was suggested that it be used as an engine testbed, its flight characteristics were entirely unsuitable for this role and it was eventually scrapped in 1924.
