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 ber plate.

WARNING: Never use a standoff between the rewall 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.
