This is the O.S. Max .55 AX Aircraft Engine with Muffler.
FEATURES: Same mounting dimensions as the O.S. Max .46 AX Advanced Bi-Metallic Liner process uses a double layer of plating material rather than one thick layer. This helps the metal bond to the cylinder and makes the plating more durable. Also, the plating process is more consistent, resulting in a more precise fit between piston and sleeve for better compression and longer life. Power Box positionable muffler Angular head design offers increased surface area for better cooling 40J Carburetor with diagonally placed Needle Valve eliminating Remote Needle Valve placement Two year limited warranty
INCLUDES: O.S. Max 55 AX ABL Aircraft Engine with E-3070 Muffler, 40J carburetor, #8 glow plug, illustrated instruction manual, 3.5" (90mm) long needle valve extension cable and two 3x35mm muffler screws
REQUIRES: Aircraft blend fuel containing 5%-20% Nitromethane with at least 18% lubricant
