The Evolution 125GX, 125cc twin-cylinder gasoline engine is ideal for 100cc- to 125cc-class airframes. Precision manufacturing with high-quality materials allows this engine to offer years of maintenance-free operation. Its standard dimensions make it possible to drop this impressive twin into extreme aerobatic performance airplanes such as the Hangar 9 Extra 300X 120cc ARF. Beautiful from prop hub to backplate bolt, the CNC-machined crankcase features tight-tolerances and a stunning natural finish. A genuine Walbro carburetor provides a premium-level of reliability and optimum performance. The dual ball bearing cantilevered crankshaft helps keep engine operation smooth. The engine mount, muffler and propeller bolt patterns match a host of other popular engines in its class which means it will easily accept a wide range of aftermarket accessory solutions. The included 2S LiPo compatible ignition allows you to fit a variety of power options. When you combine its quality construction and its ability to work with your favorite accessories, the Evolution 125GX twin-cylinder gas engine has the means to make your giant scale airplane one smooth character.
