O.S. Max .46AXII ABL Airplane Engine w/Muffler

0 Tomans

This is the O.S. Max .46AXII ABL Airplane Engine with the E-3071 Muffler. This engine features an Advanced Bi-Metallic Liner that uses a double layer of plating material rather than one thick layer. This helps the metal to bond to the cylinder and increases durability. Also, the plating process is more consistent, resulting in a more precise fit between the piston and sleeve for better compression and longer life. The E-3071 side exhaust Power Box muffler features a squared-off shape, enabling the Power Box it to fit into a variety of cowls avoiding the frustrations of compatibility issues.
