This is O.S. MAX 75 AX ABL Aircraft Engine w/ E4040 Muffler, Brand New in Box

OS 75AX is new model. It is a high performance two stroke engine designed for spot and aerobatic models.

FEATURES:
 

• Same mounting dimensions as the O.S. Max .61FX
• Crankcase and cylinder head are of aero-shape design which has the advantage of light weight and compact size.
• The new 61A carburetor needlevalve assembly has now been angled backward for safety.
• E4040 Power Box muffler design provides more volume for increased power in a very compact shape.
• Angular head design offers increased surface area for better cooling
• 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.
• Ball bearing-supported crankshaft
