So this means you’re making an RC tractor and miniature farm for it to work on right? 😄
You wish
PLEASE! 😆
YYYEEESSSS!!!!
Don't give him anymore ideas next he will make mini humans to work in his mini farm
@@madgaming6667 🤣🤣
Sounds like a mini top fuel dragster when cranked up
yes agree, especially at idle and also similar to Yamaha TZ750. 4 cylinder 2 cycle engine.... crackle. crackle crackle :-)
I think it's a gorgeous engine, I especially love the shrouded radiator and fan, as well as the centrifugal governor. Bit of a bummer that it was a rather shoddy build. Someone not mechanically inclined probably wouldn't have noticed the coolant issue and kept running that thing until the bearing surfaces were completely nuked. I kind of get it, these aren't built on a massive factory line. I imagine there aren't a lot of these built at all, so there are going to be cock-ups. That they used the wrong size o-rings, however, was a pretty big cock-up. Especially as these things aren't exactly cheap. That said, I kind of wish someone could get them to make a submarine diesel. I would be all over it like stink on poo if they did, lol...
submarine diesel ?? wasnt that normal diesel engine ?
These scale models are already expensive to the point that the market is limited,. The customers are technically minded enough that small mistakes are allowed if the mistakes are serviceable, as it helps keep the price within reason.
@@MrCcfly That depends entirely on one's definition of normal.
@@Bubu567 I would be willing to bet that much of the customer base is not mechanically inclined in the slightest, and are buying them just because they find them interesting. As a mechanic, I see it all the time. Nothing wrong with wrong with that, by the way, but it does exacerbate any production issues.
@@gvii wasnt rl subs use normal ship kind engines plus bats ??
Cool engine. I like the big flywheel low speed revving!
mesmerizingly beautiful shots, thanks
A toast to all the shell casings that left the industry to be cast in a new roll.
I believe you mean "Role"? (That's what i was thinking) 👍😀
I prefer to reload my shells a few times before turning them into can openers.
You have to wonder how much of the brass we saw in the "Million casing" artillery piles from the first (and second) world war has made its way into mundane things.
Stupid, you are a clueless ass.
@@MarkPalmer1000 Projecting much?
I really appreciate that you let us enjoy your hobby with you by showing us all these beautiful model engines.
One of the best sounding engines yet! seriously cool!
Sounds like a old Volkswagen!
@@enriqueamaya3883 I follow satan, heathen!
The tiny amount of valve lift is hilarious I need that camshaft for my small block race truck
Appears to be a number of fixes required for a new, out of the box, engine. Hopefully it wasn't too expensive.
1500$
This is my favorite content to watch!
Love your cinematic expertise!
Давно смотрю твои видео, спасибо за интересные разработки!
Это же не он разработал...
A fast RC car is something we see all the time. RC Tractor Pulling thats something i would watch. Raw tork and heavy duty gearbox working to the max.
Fabulous video! Happy New Year
I do enjoy the sound of these little engines. For some reason I'm imagining this engine being used to create a scale Armstead/Fordson Snow Motor screw drive tractor.
Awesome little engine(with its flaws), but what suprised me the most is that it got a centrifugal gouvener controlling the gas. I had to rewatch the video just to see it clearly. Those 2 rotating brass balls right behind the flywheel at 1:16
It doesn't control gas (thats controlled with his finger), but it controls the idle. I don't know if real tractor engines have a governor, but it seems resonable a tractor engine must have a governor if you are using the PTO in idle, since putting a load on the engine in the idle will sag it down, thus you cannot have a static idle that a "normal" engine has.
@@sebastiannielsen Yes, tractors, like most industrial and machinery engines always have a governor. It would be impossiblee to operate a tractor without a governor, not only for the PTO but for normal operation too.
Since most jobs are done at very low speeds the inertia is minimal while the load varies constantly and widely, without a governor it would be impossible to maintain a constant speed or even prevent the engine from stalling, the operator would have to be controlling the speed of the engine continuously and that would require a lot of physical and mental effort, distracting the operator from driving and controlling the implements.
I dig the tractor flap on exhaust . way cool
Rich man's engine, 1500 clams for that baby! Guess I'll just be watching . Great quality video 👍
I like most of your videos but this one is fantastic, one of my favorites
You do amazing work 👏🏻👌
Muy buen trabajo 👍, FELIZ AÑO VENIDERO saludos
So cute! Reminds me of a small puppy dog growling. Thanks for sharing.
Nice looking engine, sounds great
This is a Jianzhong Dong engine, and Jin is an excellent engineer. However, I haven't bought this engine, as it is very expensive and has been problematic with water leaks from the cylinder liners. He is selling improved liners, but should be providing them to previous buyers of this engine for free.
There is numerous issues with this engine. The worst issue is it’s running backwards. Jin apparently didn’t pay attention when scaling this down from the real H 75. That’s why the fan is turning backwards and the centrifugal water pump doesn’t work unless you flip the belt to reverse its rotation. It really needs a camshaft designed to run the engine the other direction. It’s still a nice engine. I bought mine off of eBay. You can get them on eBay for anywhere from $500 to $700 brand new from Jin.
Great job. It's beautiful made of mostly brass
I love this farm engine it is the coolest engine I have ever seen. It also has a great sound to it. Love your channel and content. Always waiting for the next video. ❤🇨🇦
Pretty close reproduction of the old Holt 75! Good catch on the cylinder sleeve o-rings! That could have been a really bad thing in short order. I'd love to see this running a small genset (i.e. a permanent magnet motor) and load it down with some lights and such. It would probably smooth right out with a load on it!😁
@@enriqueamaya3883 LOL, I started to follow Jesus, but he was on his way to his casa bro, and he said, sólo la familia! That the way it is with the Rodriguez clan I guess..😂
This thing is yet the coolest engine. i love it.
that`s a real nice running engine
Very cool. Nice sound.
A beautiful machine with a great sound
What a coincidence, just bought exactly the same scale today 😀
Beautiful engine!
I see an RC bulldozer in your future! And, of course, a build video to go along with it.
This channel is the best.
Those little engines are so neat. I wish those kits weren't so expensive though. As a tinkerer, maker, and mechanically minded person, I think it would be super fun to get a big box of parts and put together an engine model like that. I would totally hook up a little generator and a string of LED lights or something just to make it do something and be pretty also. If you ever have any kits you want to get rid of, I'm right over here in Southwest Washington haha.
You find the coolest engines
Tnx for your video i hope one day buy one of them...
She sounds GREAT at idle!
For a miniature engine this thing sounds really good
Pretty cool. You should make an oil bath air filter for the intake.
That thing is A Beauty.
Would make a Great boat Power house
Johnny please make a tractor for this engine. Would love to see the one like they have that do tractor pull competitons. 😂
Nice build
Luvely job. I can even smell the sweet exhaust fumes.
At 3:32 you can see that the water pump belt is crossed. I looked on the linked website to buy, and it isn't crossed. Maybe that had something to do with the lack of coolant flow? Love your vids!
Unfortunately you have to flip the water pump belt because it’s a centrifugal water pump and the engine is running backwards! They designed it with the wrong rotation camshaft so the only way to get the water pump to pump water is to flip the belt. The fan on the radiator is also running the wrong direction as it’s blowing air out the front! To correct this they really need to reverse the rotation of the engine and make it like the real one by designing a new camshaft. Unfortunately they used the public as the guinea pigs hence the leaking O-rings and wrong rotation of the engine, water pump and fan!
I'd love to see all of this little engines on a Dyno to see how they compare.
I'm not 100% positive, but I believe the oil leak is standard on the full size model also. 😅
You sir... have the COOLEST toys and tools lol. Now you need to make an RC tractor. Lol
This is what's going to power my future hybrid car, based on the trajectory of current events
You have to build a Tank around it, it perfectly sounds and performs for it 😮
These are so cool!!! I wonder what one would sound like with a "muffler"?
Every video we get closer to a diesel powered mini rock crawler.
a work of art.
Man I would love to see it put under some load and see how well the governor works
This needs to be made into a mini tractor, and @Luke Towan should build an environment for it to work in!
Looks beautiful
Benar benar sangat bagus
I have never clicked on a notification this fast before
I love watching all your videos you're very talented the V8 supercharger superchargers trying to compress the air in the wrong direction it should spend around to the outside of the case and then as the blades interact with each other it forces the air down to stay in that chamber if they spend to the inside a lot of the boost runs around the outside of it rotors back to the carburetor side and the boost will be more consistent keep up the awesome job love them all
Very cool, now it just needs an extra bank of cylinders! 😉
I once saw a similar engine in an rc hot rod car that would be a cool project for you
nice engine.
Nice engine.
I've never seen anything more beautiful! I would really like something like that! unfortunately far too expensive for me! My grandfather was a farmer in Laussa, Austria, and he had a machine like this, but of course it was big. nice greetings from Österreich
If i could get one of these to fit in one of my 1/14 semi, i'd build a hell of a truck.
No tractor sounds like this 😁👍
it's amazing how many engineers dont understand that o-rings need to squash. the idea is that it's a round cross section going into a square profile and the ring squashes into the angled corners. I've seen engineers cut a 3mm chanel 3mm deep because the o-ring was 3mm.
Yeah a new video !
My crank case covers didn’t seal at all so I used a thin piece or rubbed gasket to seal it up to hold a little oil in the crank case but it runs great
This things needs to be put into an RX7 drift car model. It has a very “rotary” type sound
Sounds sweet
You need a mini dyno. I'd love to see the numbers on this beauty.
My friend has a real version of this engine along with tank engines a jet powered riding mower Etc I can't wait to show him this video
I kind of want to see a hydrostatic transmission at this scale (as seen on late 1900s cub cadet garden tractors)
What a beauty 👌🏻😎
This is cool just wish it could be turned into a diesel or there were a diesel version. I remember there was a way to turn the nitro 2 strokes into a diesel with a fuel that had more than just diesel in it to help it burn with less compression.
So cool! Would be even cooler is you made it into a rc crawler or a towing rc tractor cause why not🤷
My favorite Microcosm engine. I have it on my channel too
Batteries to work. Hmmm. Try fitting a magneto? Dynamo? Does it have spare ooomph? At that price, & that level of QC, I won't be going for one. Nice vid, thanks for sharing.
it would be really cool to build a small hydraulic pump and then built a scale hydraulic log splitter!
Sounds like our Zetor 6245
Would love to see a 5 cylinder!
I'd hook it up to a generator. Probably make a few thousand watts with that bad boy.
Can't wait to see a Lamborghini engine (tractor or V12) and see where that leads to.
Dope AF. How's the timing for ignition handled? Is there a crank sensor?
So good ii boss 👍👍
So cool.
Please make a compilation of max rpms of all your engines.
Love the video , also what is the name of the song playing at the end of the video ? 😎👌🏼
Pretty color
Good evening Johnny q 90. I have a small four stroke engine. M 16 is in question. I am interested in how much oil should be put in the oil pan if the ratio is 4%. Should you use oil for two-stroke engines or oil for four-stroke engines? I usually put 1 milliliter of four-stroke engine oil in the oil tank and make a two-stroke mixture according to the ratio that I put in the tank.
Awesome.
Johnnyq90. What is your opinion of that engine? It’s a toss up between the gn-n100 or the h75. Would love both but can’t afford both. Trying to get the best for my buck that will last me. Thanks for your wonderful videos! Can’t wait to see what you do with it!
"Memmeh, I need it."
God that's a beautiful piece of engineering! Is it a kit? If so what it's its name please? Any information would be appreciated. Many thanks
Nice job again, you save that engine. Wen do you make your own engine from scratch, like a hybrid engine, half glow half electric in the same body. Well it's jost an hipótese.
My God, the sweet one is the little engine 😋😋
You need to make a proper full tractor gearbox for this bad boy get some torque figures at the wheels
Do you have a link where you got the O-rings from? Is 19mm the outer or the inner diameter? I have exactly the same problem with my Holt H75. After each run, most of the cooling liquid dissapears into the sump.
So it leaks oil and water from new, nice 😂
