This is the Novarossi REX R61F SPEED/13 4-Port Airplane Engine. This model includes a silver crankcase and 10405 10mm Carburetor. The R61F SPEED/13 is an incredibly aggressive powerplant for fixed wing aircraft. The redesigned crankcase and violet cooling head have been combined with a 4-port sleeve and tuned crankshaft to deliver explosive power.
