OS MAX-46AX II (7.45 cc), (40K) incl. muffler
# OS15490

OS MAX AX two-stroke engines are the latest series of powerful propulsion units, designed primarily for sport and aerobatic models. The thoroughly refined design features a unique ABL (Advanced Bimetallic Liner) insert with a two-layer surface finish made of specially developed alloys to minimize friction and wear during operation, ensuring high performance and long service life. The futuristically shaped hexagonal cylinder head with large cooling fins provides excellent cooling and enables higher performance with the same dimensions as the classic FX series. Thanks to this, you can benefit from the wide range of kits and model plans developed over the past decades for OS MAX two-stroke engines, or achieve a performance increase for your existing model with an FX engine!

OS MAX 46 AX II is a powerful two-stroke engine with a crankshaft mounted with a pair of ball bearings, suitable for all types of sport and competition aerobatic models. It is equipped with a 40K double-needle carburetor, whose main needle is oriented diagonally backward for safe adjustment while the engine is running. The basic set also includes a very efficient E-3071 (Power Box) expansion muffler. The direction of the exhaust opening can be changed by rotating the back of the muffler by 360 degrees.
