Overview

Since the release of the Evolution® 10GX small-block engine, countless modelers have discovered the benefits of gas power in aircraft formerly dominated by the .40-size glow engines. But what about the pilots who enjoy even larger airplanes in the .61- to .91-size range?

Bring the fuel efficiency and easy operation of a gas engine to your sport flying experience with the Evolution 15GX engine. It’s been designed with a standard beam mount and dimensions that allow it to fit anywhere you might use a .61- to .91-size glow engine. The 15GX will breathe new life into models designed for glow power. It’s also remarkably lightweight, even with the ignition system and battery.What sets the 15GX apart from its nitro-fueled counterparts is its phenomenal fuel efficiency. You will burn 30% of the fuel you would with a comparably sized glow engine and lower your cost of flying 90%.

All of the Evolution brand gas engines are designed from the start to provide you with excellent performance at a fraction of your previous operating costs. We have painstakingly designed each engine to insure a hassle free experience without giving away anything in expected performance or durability.
