O.S. 75AX ABL Engine
The O.S. 61FX engine is one of the most popular 60-size two-stroke glow engines produced in recent years. In line with recent industry trends to squeeze more displacement and power into same size or smaller packages – O.S. has recently released the 75AX ABL engine. The 75AX has the same mounting dimensions as the 61FX, but with a whopping 26% increase in power! It is intended to offer an upgrade in power to folks already using the 61FX or other 60-size engines, or a lighter power plant for folks who otherwise would require a larger class (and therefore heavier) engine.
