Same mounting dimensions as the O.S. Max .46 AX

Power Box positionable muffler

Angular head design offers increased surface area for better cooling

40J Carburetor with diagonally placed Needle Valve eliminating Remote Needle Valve placement

This is the O.S. Max .55 AX Aircraft Engine with Muffler. 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.

Includes: O.S. Max 55 AX ABL Aircraft Engine with E-3070 Muffler, 40J carburetor, #8 glow plug, illustrated instruction manual, 3.5" (90mm) long needle valve extension cable and two 3x35mm muffler screws

OS MAX-65AX(60J) W/E-4010A Silencer Engine OSM16521 OS MAX-65AX(60J) W/E-4010A Silencer Engine OSM16521
$309.99
In stock

Features

Ideal for trainers, sports planes and scale aircraft

Mounts in the same space as the 61FX ABL for easy drop-ins

The 65AX is 1.9 ounces lighter than the 61FX.

Newly designed 61D carburetor features an angled needle for safety.

Includes an E-4010A muffler, #8 glow plug & needle extension cable set.

Compatible with the ultra-quiet, ultra-compact E-4050 muffler.

Designed as a replacement for the long established Max 61FX, the new Max 65AX has all the features of the new AX series, such the same mounting bolt pattern and silencer bolt dimensions, making a direct replacement for most 61 class engines. The real bonus is more power and torque for the same basic external dimensions.

Like all the AX series, cooling has been improved by the use of deep finning on the crankcase and cylinder head combined with the new fin pack shape.

The silencer is effective and a great benefit to flying fields with sensitive noise issues. Effective silencing is very much part of the AX design philosophy.

Carburation is the usual OS 'exemplary' standard and very much why OS engines are regarded as the best! That comes from careful design and testing allied to stringent manufacturing standards.
