Designed by Stelio Frati, the Rondone was produced in two versions; the two-seat F.4 Rondone I and three-seat F.7 Rondone II (originally known as the Airone).
A batch of ten Rondone I two-seaters were built by S.A.I. Ambrosini, and additional aircraft were built by Legnami Pasotti & Co.
Both versions are generally similar externally.
