The 55AX is better than ever, with an improved carburetor and muffler. You get the same phenomenal power, with the convenience and safety of a rear angled needle valve on the carb and a squared off muffler for easier cowling installation. If you want .50 scale power that fits conveniently in .40 size planes, get the 55AX and get flying! ABL uses two alloys to provide a durable layer between the brass liner and piston.
