This is the .52NX Sport Helicopter Engine from Evolution Engines. 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. 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 in any 50 class helicopter.
