Ideal for trainers, sport planes and scale aircraft. Review: This is a very well crafted motor. - Haven’t bought a glow engine in several years. I must say, I a quite impressed with the quality of this AX motor. After break in, the idle is very constant, power or best of any engine this size I’ve ever owned and starts super easy. Only issue I had is the o-ring on the muffler allows the tail piece to rotate and loosen the bolt holding it together. To fix that, I removed the o-ring, tightened the bolt and jamb nut, problem solved. Review: Another great running OS Engine - I bought this for a Hanger 9 Ultra Stick. It started right up using my starter on the first attempt. Recommend this engine for anyone looking for a .60 size engine. ## Features - The perfect power plant for trainers, sport planes and scale aircraft, offering outstanding reliability and easy tuning. - Mounts in the same space as the 61FX while being 1.9 ounces lighter and delivering 5 percent more power! - Compatible with a wide range of propellers and the E4050 In-Cowl Muffler (OSMG2842), which offers a choice of side or inverted exhaust outlet angles. - Pair with Tower Hobbies TOWER Power 10% Airplane Fuel (TOWP1600, sold in quarts) for optimal results. - Comes with a two-year limited manufacturer’s warranty. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004QJVHVC | | Brand | OS Engines | | Brand Name | OS Engines | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.5 out of 5 stars 17 Reviews | | Included Components | 16521 65AX ABL .65 Airplane Glow Engine w/Muffler | | Item Dimensions | 7.7 x 6.4 x 4.2 inches | | Item Type Name | Glow Engines, 2 Stroke, Airplane | | Item Weight | 1.5 Pounds | | Item dimensions L x W x H | 7.7 x 6.4 x 4.2 inches | | Manufacturer | Hobbico Inc | | Manufacturer Part Number | 16521 | | Manufacturer Warranty Description | 2 year limited warranty | | Material | Metal | | Material Type | Metal | | Model Number | OSMG0558 | | UPC | 787799842607 | | Vehicle Service Type | Car | ## Product Details - **Brand:** OS Engines - **Item Weight:** 1.5 Pounds - **Item dimensions L x W x H:** 7.7 x 6.4 x 4.2 inches - **Material:** Metal - **Vehicle Service Type:** Car ## Images ![O.S. 65AX Glow-Powered Aircraft Engine with Advanced Bimetallic Liner and E-4010A Muffler - Image 1](https://m.media-amazon.com/images/I/71GHBTbo5LL.jpg) ![O.S. 65AX Glow-Powered Aircraft Engine with Advanced Bimetallic Liner and E-4010A Muffler - Image 2](https://m.media-amazon.com/images/I/61Tn9CkuorL.jpg) ![O.S. 65AX Glow-Powered Aircraft Engine with Advanced Bimetallic Liner and E-4010A Muffler - Image 3](https://m.media-amazon.com/images/I/61LOhT9K1OL.jpg) ![O.S. 65AX Glow-Powered Aircraft Engine with Advanced Bimetallic Liner and E-4010A Muffler - Image 4](https://m.media-amazon.com/images/I/61Ku9hpM9lL.jpg) ![O.S. 65AX Glow-Powered Aircraft Engine with Advanced Bimetallic Liner and E-4010A Muffler - Image 5](https://m.media-amazon.com/images/I/61DB+PRk1aL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a very well crafted motor. *by T***. on March 23, 2021* Haven’t bought a glow engine in several years.
