Introduction
Thank you for purchasing an Evolution
place today. Evolution is committed to you having a positive experience and a lifetime of great
operation with your new engine.
It is important that you read the engine manual before starting the engine for the first time.
Evolution radial engines have different requirements than engines that you may have operated
in the past. The manual provides important information for installing the engine, selecting the
correct propeller, fuel requirements and proper engine break-in procedures.

Installing the Engine in the Airframe
Properly installing the engine to either the airframe or an engine test stand for break-in is crucial
to getting the most power and longest life from your engine.
WARNING: Always attach the engine mounting ring to a flat plate surface, such as
6–8mm plywood or carbon fiber plate.
WARNING: Never use a standoff between the firewall and the mounting ring. Vibration
between the standoff and the mounting ring will damage the mounting ring and cause
the engine to separate from the airframe.
