Introduction
Congratulations on your purchase of the newest and one of the most technically advanced 2-stroke gas model airplane engines in
the world. Whether you are new to the sport of model aviation or an experienced flyer, you will enjoy the features of the new Evolution
®
GX engine.
Evolution engines are designed to be the most powerful in their class, extremely easy to start and operate, and provide years of
enjoyable service. These engines incorporate many unique features designed to ensure success with your new engine.
This user’s guide is intended to provide the basic information required to operate and maintain your Evolution GX 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 shop or flying club can put
you in touch with an experienced pilot in your area.
Before using this engine, please read these instructions carefully.
