nice bit of kit

Could u please send its attachment diemensions i have tbi but i want to have links and attachments drawinga

Good visual video .. ruined with dreadful music

The word on the street is these engines are junk

Why the 70s porn music?

In use Rotec product here: kzbin.info/www/bejne/gp2zpYCMns98sNU

Do not put this in the air! It will fail. Use it as a paperweight only!

LORTEMUSIK

Allways this f..cking music

Well.... Lee Hodgson's design looks great at this size.

George Benson vs Rotec Radial?? Both are absolute winners!

Oh my God, really? Wouldn't Black Sabbath or something else have been a little more appropriate if you HAD to put music in it, it's a radial engine not a purse or a pair of ballet slippers.

I think the focus is off. Looks blurry to me.

I guess any music played during this great video would sound good. Thx!

Benson's a great jazz musician; i saw him live twice Back in the Day. BUT, how 'bout some info on the engine including its intended applications? Are these built as replacements for vintage engines? I'm figuring it's 3.6 Liters, not 3600 cubic inches!

I didn't see anything related to the lubrication system (drilling the crank, oil pump, etc) on this video. But I assume it must have a dry sump system. I wonder if it uses as much oil per hour as most old radials.

The video was excellent. The music...feh! Next video...no music. I'll be lurking to make sure...

Awesome engine and engineering, terrible music, and that engine on that teeny trailer with any kind of throttle is the most unsettling thing I have seen all month. Sorry to be so negative, but nobody here with a mechanical mind is going to want to hear music.

i wonder how the lubrication system for this engine,

Awesome machine work!

very good video, brasil ok.

My question is what are the design criteria for a radial engine. Why use 9 cylinders when that can be achieved with 2, 4 or 5 in V? thank you.

such gay music.

do you think that the music is about irrelevant as it gets?

That's a gorgeous round engine!

I can't believe you would take a perfectly good George Benson soundtrack and contaminate that great musical masterpiece with a CNC radial engine build.

All the time and precision in this build and you trash it with music. . .no thought went into that did it boys! Consider matching your video production skills to your tooling skills. Even with CNC this is not an easy build, I would've liked in dept details concerning tooling difficulties along with maybe material choices. . . consider that next time . . Please ;)

this thing must have emense torques there's no way they did all that for 150 horses

The music is the best album by George Benson produced by Quincy Jones. Unfortunately, Benson never collaborated with Jones again. Rather than sing racy lyrics for Jones, Benson prefers to make "hot licks" with his guitar.

Come on people, that's just a cooling "propeller", it doesn't even have power enough to tip over the trailer when he revs the engine.

You could design the electronic engine to generate a certain hertz that would generate ultra low temperatures and create a new cooling system? Cryogenic piston technology? Is it the motion of the piston or the vibration that causes low temperatures? If you understand what I am talking about could you not make stand alone refrigerators, air conditioning units and electrical power generators with this engine design? I don't know do you? ; )

Try induction used for cooking with Manson engine design and make this an electronic rotary engine and get away from using fossil fuels. You could try electromagnetic kicked pistons has well. Novartis

Sure would be cool if they built a 2 row engine.

Glorious.

Stop that fucking music!!

Cool process, it inspires me to build a 1/2-scale human-operated B24 or B25. Since it only needs to carry a pilot & maybe a passenger, 150 x 2 would be perfect for a cool twin-engine ride!

NOW INCREASE THE BOOOOOOSSSSTTT.....

Actually, some of us came here to be educated and NOT listen to music. We could stand in an elevator for that. These guys have so much knowledge and have done so much hard work and they tell us nothing? This is a rather horrible format! Thanks for the effort and best of luck.

I would like to have that engine on my Ultra lite.

Just a little scary standing so near those propellers with the engine mounted to a trailer, eh?

Music was good but should have stopped when you turned on the engine, we all love to hear sound of such engines.

Great video of construction and running. The music over it takes away and is totally irrelevant.

In this video the engine has less that one hour its near new and as you can see I dont have the rocker caps on yet.

Great engine. But I would have had issue with firing that beast up on a platform WITH WHEELS.

just think of the speed the pistons are going

Oh! Why that music?

I'm glad that I saw one engine work correctly the first time rather than sputter and stall half a dozen times like the original ones seem to do in the videos. This one is new, so that makes sense. The other original demonstrators must be all out of tune and not synchronized correctly. This is the way it is supposed to work. Thank you. Aarre

Leu eu gosto muito de assisti esses vídeos pra mim aprender alguma coisa

deinterlace

I would like to put one of theses on an air boat. It's a beautiful piece of work, nice job.
