Homemade radial engine 9 cyl 

Between the engine and the metal prop, how much more beautiful can it get? Bravo!

You da man! I build mostly single cylinder toys, sometimes radial bash-valve ones, but THIS is truly a labor of love. Well done.

If you would apply a ring muffler, I think this engine would sound even more gorgeous. Great work 👍👏

Excellent work. Beautiful engine.

Was für eine technische Meisterleistung !

Just found your channel and Subscribed. Nice work.

Great job!!!❤

Ausom job.

Great sound!

How is it lubricated? Oil in fuel? I don't see an oil tank or dry sump plumbing.
