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.
