55AX ABL .55 Airplane Glow Engine with Muffler (OSMG0557)

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!

The large-chambered muffler reduces sound without reducing power.

The 40K carburetor includes a diagonally placed needle valve so there's no need for a remote needle valve.
