55AX OS Engine

More muscle for .40 sized airplanes

Increase displacement in your 40-size model the easy way: just drop in a 55AX engine! You’ll enjoy more horsepower for swinging bigger props — which means improved 3D, precision and sport flying. Best of all, there’s no modifications required!

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.
