Saito FG-73 R5 Full Upgrade With MMM Hardware 20 x 10 Biela 4 Blade Prop 600 RPM - 5500 RPM 

That 600 rpm idle at the end sounds awesome...love it!

That prop is nice and quiet... at least in the phone footage. Really lets the engine's tune come through.

Gosh those radials sound sweet!

Great work as always sounds exceptional

That sounds beautiful

perfect low rpm run.....great sound....... 👍

Wonderful sound!!!

I wish Morris' Mini Motors Limited would respond to questions on these RU-vid videos.

What do you mean by saying upgrade? Whats is diff from the original and what do you get from this upgrade?

If someone is interested in better understanding the costs and info about what might be a bearing install for the 32:1 oil content, how can we get that info? I checked the MMM website and couldn’t see any pricing or info about the modifications shown here :).

Where is Mr Bobby’s?

Oil gas mixture? 2 cycle or 4? Sweet!

i got a question about the original backplate do you know of or have the dimensions? i couldn't find them anywhere when i looked online

Propeller rpm at max power?

What is the maximum weight of an airplane can this engine carry?

Прекратите газовать, как на автомобиле, для авиационного двигателя, тем более с пропеллером это вредно!!!
