The O.S. MAX-46FX is a highly popular, classic two-stroke glow-ignition RC aircraft engine manufactured by O.S. Engines. Known for its reliability and excellent power-to-weight ratio, it was widely used for small to medium-sized trainer, sports, and aerobatic model airplanes. Although it has been officially discontinued and succeeded by the O.S. 46AX series, it remains a staple on the secondary market and among vintage RC enthusiasts.
