Although earlier SIAI aircraft had been employed as racers, the single-seat S.17 was SIAI's first specialized racing aircraft designed as such. Its 231 kW (310 hp) Ansaldo San Giorgio 4E-14 engine gave it a top speed of 290.9 km/h (157.1 kn; 180.8 mph).[1][2]
Operational history
The S.17 participated in the 1920 Schneider Trophy races at Monaco, but crashed during the final take-off and did not finish.[3]
