Designed to combine maximum power with razor sharp throttle response in the smallest possible crankcase, the 55AX has the same mounting dimensions as the popular 46AX above, but an increase in power to 1.70PS. The dramatic AX fin styling is used for optimum cooling and the rearward angled needle on the the type 40J carb makes adjustments safer. Perfect for sport, scale and aerobatic models.

The distinctive shape is hard to ignore, and with peak power of 3.1PS at 9000RPM, you can be sure that this engine loves big propellers! OS recognised that engines of this size are often used in scale models and have developed a silencer system that allows adaption to some of the ''tightest'' installations. The carburettor features a neat needle valve that protects fingers while adjusting, yet is simple & accessible.
