The Evolution 152GX is a 152cc twin gas performer in the Evolution line of brutally powerful gas engines. This power plant has been engineered and manufactured specifically for large-scale and aerobatic airplanes. Its porting design provides very high power-to-weight and power-to-size ratios while the rear intake design provides higher power outputs. If you are interested in more power for your 40% airplane, you will be pleased to know the Evolution 152GX is among the most powerful in its class. And, because this engine uses common mounting methods, it is easy to adapt to both existing and new aircraft designs. This purpose-built engine will give 40% planes the power for unlimited performance.

Superior porting technology, Walbro carburetors, ball bearing-supported crankshafts and modern electronic ignition systems are all hallmarks of the Evolution gas line.
