Continuing the next stage of Evolution® engine technology. The NX series is designed to provide a unique combination of powerful performance, reliable engineering and remarkable ease of use. You already know how impressive the pioneering 1.00NX is. Now Evolution presents the new .52NX. The .52NX is the same size and weight as ordinary .46-size glow engines, but packs more of a punch. Its displacement of .52 cubic inches provides sport models with plenty of get-upand-go without adding weight. And since it’s an Evolution engine, the .52NX has the innovative low-speed SetRight™ needle valve with a lever that makes easy adjustments and takes all the guesswork out of operation. True ABC construction, including a brass liner coated with chrome plating, withstands abuse and provides long-lasting performance. And with its upward swooshing heat fins, blue highlights and majestic Evolution Engines logo,
the .52NX looks awesome mounted to an airplane.
