Savoia S.21F by FineMolds
"Experimental Hunting Plane"

Google translate from box panel: "With Fio design changes now the red SAVOIA S.21 fighter has become the legend of the Adriatic thanks to a woman who cannot be forgotten: Fio Piccolo. You are an excellent engineer and modified the S.21 fighter destroyed by rival Curtiss in the war. By installing a new FIAT AS.2 engine and modifying the wing design, Fio was able to create a fighter with excellent performance."
