Evolution Engines

With its lightweight magnesium crankcase and advanced porting, the 45GX2 offers the highest power-to-weight ratio in the Evolution® Gas lineup. Aimed directly at the very popular 50cc class of models, the Evolution 45GX2 will provide that vertical thrust you crave for 25% to 30% scale aerobatic planes like Hangar 9’s 27% Extra 260 ARF.
