Evolution 20cc Petrol Engine with Electronic Ignition

The Evolution 20GX is a 20cc small block gasoline engine designed for .90- to 1.20-size airplanes. 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. It’s also remarkably lightweight, even with the ignition system and battery. With the included 2S LiPo ready electronic ignition and muffler pressure-regulated type carburetor, easy starts and tuning are a breeze, allowing you to take the model to the air in no time.
