Introduction

Congratulations on your purchase of the newest and one of the most technically advanced 2-stroke model airplane
engines in the world. Whether you are new to the sport of model aviation or are an experienced flier, you will enjoy the
features of the new Evolution

®

Engines .40NX Engine.

The Evolution .40NX Engine is designed to be the most powerful in its class, extremely easy to start and operate, and
provide years of enjoyable service. It incorporates many unique design features, such as our Set Right™ needle valve
assemblies. Every feature is designed to ensure success with your new engine.

This user guide is intended to provide the basic information needed to operate and maintain your Evolution .40NX
Engine.

Every Evolution engine has been baseline adjusted at the factory and is ready to fly . We recommend a 20-minute break­in period to become familiar with the engine.

Important: While the Evolution engine is extremely easy to operate, if this is your first experience flying a model airplane,
it is highly recommended that you have the help of an experienced modeler during the first few flights. Your local hobby
store or flying club can put you in touch with an experienced pilot in your area.
