Flight testing was carried out at San Diego, but performance was found to be unexceptional, comparing very poorly to the contemporary Beechcraft Bonanza, which could cruise at 165 mph (143 kn; 266 km/h) on only 165 hp (123 kW). With a maximum speed of only 142 mph (123 kn; 229 km/h) the Model 106 was hopelessly outclassed and Convair abandoned development, scrapping the sole prototype, (regn. NX40004, msn. 1), in 1947.[1]
