Overview

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.

The 45GX2 comes equipped with Evolution’s new GX2 Ignition System. The GX2 system can be powered by most any 2-cell Li-Po pack without the need of a regulator. It also features a sophisticated auto-choke function, timing that can be programmed for mufflers or tuned pipes, and an optional, remotely-mounted LED tach.
