However, although the Dragonfly gave much more power than the Clerget, it was hopelessly unreliable, with one test pilot stating that "... I never remember being able to get all cylinders to fire at the same time" and "I don't remember that we got a single successful performance with the engine."
169:
The first prototype appeared early in 1918, but it was overweight and handled poorly. It was quickly rebuilt with much larger two-bay wings, which improved the handling, but the prototype's performance remained disappointing, not even matching that of the aircraft it was intended to replace. The poor
170:
performance was in part due to the
Clerget engine's failure to provide the expected power, producing only 200 hp (149 kW) instead of the expected 260 hp (194 kW). The second prototype was fitted with a 360 hp (267 kW)
180:
Work on a third prototype was abandoned because of the failure of the first two aircraft, although the second prototype continued in use until at least March 1919 carrying out test flights in futile attempts to solve the problems of the
Dragonfly.
