O.S. MAX-46AXII - 7.45cc 2-Stroke Airplane Engine
Experience the all-out power of the O.S. 46AXII with muffler! Features include a squared-off E-3071 Power Box muffler, a 40K carburetor with a rear angled needle valve, a ball bearing-supported crankshaft and an A3 glow plug.- Advanced Bi-metallic Liner 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. The process is also more consistent, resulting in a more precise fit between the sleeve and the piston for better compression and longer life.
- E-3071 Power Box™ muffler with a squared-off shape enables it to fit in a wide variety of cowls.
- 40K carburetor with rear angled needle valve for added safety.
