OS MAX-65AX (10.63 cc), (60D) incl. Silencer
# OS16521

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

OS MAX 65 AX is a powerful two-stroke engine with a crankshaft mounted with a pair of ball bearings, suitable for sport and competition aerobatic models of all kinds. It is equipped with a 61D double-needle carburetor, whose main needle is oriented diagonally backwards for safe adjustment while the engine is running. The basic set also includes a very efficient expansion damper of the E-4010 type (Power Box). The direction of the exhaust opening can be changed by rotating the rear of the damper by 360 degrees.
