Description

OS Max .55 AX engine with the E3071 Muffler.

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!

Same mounting dimensions as the O.S. Max .46 AXII
Advanced Bi-Metallic Liner process uses a double layer of plating material rather than one thick layer. This helps the metal bond to the cylinder and makes the plating more durable. Also, the plating
process is more consistent, resulting in a more precise fit between piston and sleeve for better compression and longer life.
Angular head design offers increased surface area for better cooling
40K Carburetor with diagonally placed needle valve eliminating remote needle valve placement
