.46AXII ABL Glow Single with Muffler, by OS Engines

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