Since the release of the Evolution® 10GX small-block engine, countless modelers have discovered the benefits of gas power in .40-size airplanes. It’s so easy to run that even beginners with no engine experience are getting into the thrill engine-powered models offer. But what about the pilots who enjoy even larger airplanes in the .91- to 1.20-size range?
Now Evolution brings small-block gas fuel economy and ease of use further into your sport flying experience with the new Evolution 20GX engine. It’s been designed with a standard beam mount and case dimensions so that it will fit anywhere you might use a .91- to 1.20-size glow engine. 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. On average, you will burn 30% of the fuel you would with a comparably sized glow engine and lower your cost per flight by 90%.
> Lightweight construction based on the Evolution 91NX glow engine
> Designed from the ground up specifically for RC use
> Gasoline fuel delivers low operational cost and simplicity
> Great power and performance for demanding RC pilots
> Lightweight electronic ignition provides easy starts and superior reliability
> 2S Li-Po battery compatible ignition without a regulator provides long run times
> Standard beam mount installation makes conversion effortless
> Low oil content fuel requirement makes operation cleaner
> Better fuel economy means a smaller fuel tank requirement and weight savings
