OSM16521 OS Engines MAx 65Ax Nitro Aircraft Engine, .65 Size with E-4010A Silencer, OSM16521

The versatile 65AX ABL from O.S. makes a great power plant for trainers, sport planes and scale aircraft and best of all, it mounts in the same space as the popular 61FX ABL for easy drop-ins! Includes a newly designed 61D carburetor, an E-4010A muffler, #8 glow plug and needle extension cable set.

Features:

• Ideal for trainers, sport planes and scale aircraft
• Drops in easily in the same mounting space as the O.S. 61FX ABL
• ABL-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.
• Re-designed 61D carburetor with a rearward angled needle valve for safer adjustments
• O.S. Engines two year limited warranty through Hobby Services beginning at date of purchase
