Available for same day despatch Mon–Fri if ordered before 2pm, when possible
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.
ABL (Advanced Bimetallic Liner) uses two O.S.-developed alloys to provide durable barrier between the brass liner and piston.
-
Mounts directly into the bolt pattern for a 46AX.
-
A diagonally-placed needle eliminates the need for a remote needle valve
-
The 5-sided, angular head design looks great and significantly increases surface area for better cooling.
