This is the O.S. Max .46AXII ABL BB Model Airplane Engine with Muffler.
              Ideally suited to sport and aerobatic aircraft.

FEATURES: Advanced Bi-Metallic Liner. This process uses a double layer of
            plating material rather than one thick layer. This helps the metal
            to bond to the cylinder and is more durable. Also, the plating
            process is more consistent, resulting in a more precise fit between
            piston and sleeve for better compression, longer life.
          Side exhaust
          E-3071 Power Box muffler with squared-off shape enables it to fit
            into a variety of cowls
          40K carburetor with rear angled needle valve for added safety
          Ball bearing-supported crankshaft
          Two-year limited warranty through Hobby Services beginning at date of
            purchase

INCLUDES: One O.S. Max .46AXII ABL BB model airplane engine w/muffler, A3 glow
            plug, two 3mm x 35mm cap head muffler screws, extension cable for
            remote needle, 3mm x 35mm cap head muffler screws, warranty sheet,
            decal sheet, and illustrated instruction manual

REQUIRES: Fuel containing 5%-20% nitromethane with at least 16% lubricant
          Most of the fuels we carry meet or exceed the lubricant content
            required for optimum performance and maximum engine life. In the
            past, the conventional lubricant content used in fuel was 18%. But
            with new advanced technologies, fuels like Red Alert and O'Donnell
            for example, have a better quality of lubricants even though the
            percentages of lubricant content are lower. These high-tech
            lubricants provide exceptional cooling and protection.
