Since the release of the Evolution™ 10GX small-block engine, countless modelers have discovered the benefits of Petrol power in aircraft formerly dominated by the .40-size glow engines. But what about the pilots who enjoy even larger airplanes in the .91- to 1.20-size range?
Bring the fuel efficiency and easy operation of a Petrol engine to your sport flying experience with the Evolution 20GX engine. Its new pumped carburettor makes fuel flow uniform and consistent regardless of fuel tank location and makes needle valve adjustment easier. It’s been designed with a standard beam mount and dimensions that allow it to fit anywhere you might use a .91- to 1.20-size glow engine. The 20GX will breathe new life into models designed for glow power. It’s also remarkably lightweight, even with the ignition system and battery. But what sets the 20GX apart from its nitro-fueled counterparts is its phenomenal fuel efficiency. It takes only 30% of the Petrol/petrol to run the 20GX the same amount of time it would to run a comparably sized glow engine. That’s an amazing efficiency level that results in a cost per flight difference of 90% on average to you.
All of the Evolution brand Petrol 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
