Here is the part two. It is not really instruction but shows all the components that makes the engine you can put on RC airplane.

To understand exactly what is expected weight of this engine here are all the parts put on scale.

1.Engine

Engine alone with cut all excessive aluminum. This engine will be used with glow plug, so I removed magneto parts. If you want to use electronic ignition the pickup can be easy mounted near the front bearing. Spark plug / glow plug is removed as I wanted to show it separately.

Total engine weight is 22.8oz
