The first prototype was followed by the second prototype early on during the following year. During testing, the aircraft reportedly attained in a dive free of negative tendencies such as flutter and other aeroelastic issues; although it could achieve only in level flight due to a lack of engine power. Nevertheless, this capability was superior than the performance of the competing Fiat G.50 Freccia, Reggiane Re.2000, A.U.T. 18, IMAM Ro.51, and Caproni-Vizzola F.5; of these, the Re.2000 was seen as the most capable of the C.200's rivals, being more maneuverable and capable of greater performance at low altitude but lacking in structural strength.
