This is the O.S. Max .46AX ABL BB Model Airplane Engine with Muffler.
     Ideally suited to a variety of R/C aircraft including trainer, sports
                        aerobatic, and scale types.

FEATURES: Redesigned remote needle holder is separate bracket, not part of
            backplate
          Advanced Bi-Metallic Liner. This process uses a double layer of
            plating material rather than one thicker 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
          Newly designed sport muffler with squared-off shape
          40G carburetor
          Ball bearing-supported crankshaft
          Two-year limited warranty

INCLUDES: One O.S. Max .46AX ABL BB model airplane engine with muffler, A3 glow
            plug, 2-1/4" (57mm) section of tubing for remote needle, two
            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.
