All your videos are inspiring and relaxing, keep up the great work!! P.s. Dont forget about the supercharger. Even if it doesn't make significant boost it's still cool to hear an RC V8 whine!!
What a bummer, that was a cool little v8. Would definatly love to see a scale dyno to test with, im sure you could figure out the numbers for calculating the results :)
It's insane how skilled you are on crafting such small pieces with this level of precision while making everything work together. I'm looking at the gearbox and wondering if heat can be a thing in the long term and if it's possible to add something to cool it down. Another thing that came to my mind is to try and balance the wheels (maybe craft some yourself with aluminum? Or just add some weight where neede to balance it off) in order to get less vibration, more grip and less mechanical stress on chassis, suspensions and probably the differential too. I know nothing about rc cars and I'm not a mechanic either so I'm just trying to guess possible issues and most likely saying things you already noticed yourself or decided they are no big deals
0:21 rather than brass, you have two other options (that go two different ways, depending on what you want) that are softer than brass, but stronger than plastic. Tin and aluminium. Tin's going to be heavier and aluminium lighter. I'm not sure what you want of that part, but brass may be too strong and break other bits. Just a thought thrown out there. Merry Holidays! Next year you're going to hit 2 million subscribers for sure! :)
Kinda yes but I doubt that AL will have the hardness too resist the inpact of the dog clutch without Plastic deformation but for sure if he isn't gonna asing a point of fallure the system will do it for him 😅 I recommend a shock absorbing ruber disk in the drivetrain
12:36 Not the case. It blew up because the hardware in these engines is gouda grade chinesium. Replace all the hardware with true grade 10 hardware, fix/replace the oil pan, slam it back together, and I bet it won't do that again.
Can’t wait to see it up and running again!! It’s such an awesome build. That guy on here said “it’s just a kit, anybody can build it” talking about the engine kit that you START with… is he blind about ALL the custom components that you design and make? Or the car that the engine goes in? He is obviously jealous of your engineering skills and your ability to build something so freaking awesome!! I’ll bet that dude has trouble building a Tamiya car😳… lol
Awe, man! She threw a rod. This is bad news for you, and great news for me. Now I get to see you make replacements. I'm glad to see your transmission is coming along too. If I had to guess why second gear is not engaging, I would say it's maybe the hard edges where the dogs mesh. Or maybe too much friction.
Wow! Complimenti davvero! Io Avrei evitato di portare il flusso di aria calda in arrivo dallo scambiatore ( radiatore) così vicino al filtro di aspirazione. Comunque è un Problema facilmente risolvibile❤ Buon progetto! ❤❤❤❤
You need to make a completely enclosed transmission/gearbox filled with oil. That way you'll have less, heat, damage, wear and tear. It will help with more consistent/smoother shifting. Also get yourself a real (4 stroke design) Mini V8 that runs on gasoline instead of glow fuel. Nitro engines don't last as long and need rebuilding after so many hours not to mention glow fuel is like $50 a gallon and sometimes hard to find. If you do decide to go with another (2 stroke style) V8 glow engine, use a fuel with higher oil content.
Jhonny, Glow Plugs (spark plugs) are heat graded meaning if you use a hotter plug like the ones you replaced, will advance ignition timing, cooler plug will have opposite effect. your Rod failiure could be because you have inadvertantly advanced the ignition timing!
yes your correct, its a glow plug, johnny reffered to it as a spark plug in his video. In any case Not all glow plugs are the same, they are heat graded also there is a diffrance between 2 stroke and 4 stroke glow plugs. it gets a little complicated, but you can measure a noticable diffrance in performance. Peramiters such as compression, nitro content 2 and 4 stroke and desired rpm all come into play. a glow plug manufacture called Model Techniques made an extensive data sheet, listing cases for a full range of their plugs. Back in the Day i had a hot rodded Spitfire using up to 40% nitro methane. Selecting the correct plug was essential... in any case i more than doubled the power( according to the propeller it could swing) Fun times =) @@Wazaarbazaar
Somthing else to consider maybe to add a varible resistor in the glow plug circut, inorder to adjust the voltage going to the glow plugs, this would in theory allow you to dial in when the mixture ignites, like a crude method of advancing/retarding when the mixture ignites inside the combustion chamber, just a thought.
yes i wasnt 100% sure, i do know some glow motors used to run a constant current to the plugs to prevent them from going out. in which cast it would be possible to run a very cold plug, and utlise a constant current and use a resistor to ignite the fuel at the desired timing! @@russcole5685
Happy holidays my friend, been here waiting to see if you were going to work on this car before the end of the year. Can't wait to see all of your hard work pay off and see you enjoying this beautiful car. Keep up the awesome work you're doing.
Honestly it’s a very cool car. With the size of it, 1/4 would be a child power car and 1/3 would be a go kart size! Keep it up, I’ve been watching you for years and hopefully more years to come.
Bro you do the most beautiful and amazing job on your machine work and that’s coming from a gun smith who machines guns on the lathe and I thought my stuff was small and tedious - not even a match to what you do
Ouch, too bad about the engine, but nice work on the transmission. A little tweaking on the brass dogs will probably get it to shift. They're always fairly loose in a MC transmission. Usually the 'pin' side is almost round, rather than elongated, to allow plenty of slack for engagement.😉
Theres another guy on here he trying to stuff same motor into a 1/10th infraction stunt truck Look at this rig its on another level. The build quality 👌🏼 is amazing, heck of a job sir!!!!
Real RC hobbyist right here, making your own parts like we did back in the good old days, not this ready-to-crash all-plastic stuff they’ve got out today. We had RC planes for decades with very few problems, but when RTF drones that use a phone as a controller came out, we got all these new regulations. I’m all for getting more younger folks into the hobbies but enough of them don’t pay their dues first and just get into trouble with stuff.
i always am just waiting for JQ90s next video. in the world today surly biggest gripe has got to be the time between vids. but to my personal opinion the just next level build ideas, and then the powerplant choices with the overall functionality and melodic cohesion. is second to none. JQ focuses on perfect harmony must be achieved because nothing else is acceptable. oh i for got to mention that he's gotta be a self taught, at least in the years ive watched JQ i dont remember seening any custom parts ever tossed to machine another. first shot and never wastes material. JQ when machining could more likely run circles around most machinist instructors here on the tube.
One of the worst days ever is the one where your engine decides to put a leg out of bed. I've been that soldier once, not an experience I would care to repeat. Love your videos, sorry everything didn't go to plan, Dude.
Uh oh, Rodney came a knocking. I've only ever seen that on full size engines, but I guess when you're experimenting and pushing the limits, even the scale engines can do the same thing.
Well that was a bit of Christmas cheer for me a new video. Great work as always, I love watching how you put all this together, it is a work of art. Good luck for 2024, I'll be waiting 👍❤️
You would have to reinforce some parts of the engine so that it is not prone to catastrophic failures since those engines are not designed for such extreme tests. I hope you can soon solve all the problems since I want to see that car in action, it is incredible.
Mini dyno please. Omg. How much dog power is this baby???? 😂😂 This is a bad ass test stand. Not going to lie. Im jealous!! You need to patent this design. And it blew!?!! Awesome
Wow, the conrod left the chat! Fortunately, it only damaged the oil pan and not the cylinder block!! It's time to built a new version maybe? Happy New Year!!
The dogs on gears in racing transmissions are usually not fully 90 degree to the gear, there's a small angle so that if the gear only slightly engages it will pull itself more into engagement.
Let's be real here man this is fkn awesome one of the coolest vids I've watched in a long time the talent it takes to do some of this work is far beyond my process of thinking lol 😆 so cool brotha thanks for the vid
Additional: Can you show a close up of the crankpin where the rod came off? and the running surface of rod and cap? Just curious how those cranks and rods holds up...
I’m super excited to see what you have in store for us next year The gearbox evolution is amazing, and I assume… based on certain events… that we might be seeing some custom internals soon. Btw, at what point would transmission fluid of some sort become effective? Love everything as always, keep up the great work and amazing content 👍

What gets me about these engines is. They can range anywhere between 1,000 and 6000 each when he gets a new one he opens it up and runs it right out of the box which usually results in terrible performance and something being broken. Then in the next video you see that you need about $100,000 worth of tools and equipment and about a million dollars worth of knowledge to keep them running
Considering its an FR car from what I can see, maybe as a potential exterior, you could make it look lile theazda Rx-Vision GT3 car. Yes, it doesnt have a v8 but a rotary 4 but who cares! It looks cool and will suit the style of the drivetrain and engine!
You should make a mini dyno 😊
Thats what a rolling road would be
With more sensors and maybe heavier rollers this could be one
He did and it was pretty shit.
Good idea man 👍🏻👍🏻
Half way there already.
Damn, it even throws a rod to scale! ❤Built for a good time, not for a long time! 🤣
I was thinking the same. That is a proper engine failure.
Yes I thought exactly the same! I must admit...I was impressed!
The same thing happened to my Skoda Octavia last year 🥲
Same thought. Amazing!
XD
I like that your bandsaw seems to have a turbo blowoff valve :)
Sounds more like a loose sawbelt
All your videos are inspiring and relaxing, keep up the great work!!
P.s. Dont forget about the supercharger. Even if it doesn't make significant boost it's still cool to hear an RC V8 whine!!
No doubt! I think the thing worked, he just didn't richen the mixture enough so it bogged.
What a bummer, that was a cool little v8. Would definatly love to see a scale dyno to test with, im sure you could figure out the numbers for calculating the results :)
🎄Merry Christmas🎄Johnny, Thanks for another year of awesome content! I can't wait to see what you have in store for us in 2024!
That full throttle on first gear was amazing. Can't wait the next video

Nah I'd suggest oil infused bronze, it's specifically made for sleeve bearings and the like so they self lubricate.
12:36 Not the case. It blew up because the hardware in these engines is gouda grade chinesium. Replace all the hardware with true grade 10 hardware, fix/replace the oil pan, slam it back together, and I bet it won't do that again.
Oil pan failures (when the oil pan fails to hold the contents of the engine) get you every time.
✌🎅👍
The good old fashion throwing a rod trick huh? Never gets old.
Can’t wait to see it up and running again!! It’s such an awesome build.

This is an awesome Christmas gift to see this thing in action! I love tiny V8 engines put to actual proper work!
That shot where you had the entire roller on the lathe and removed the top layer. So. Good. Also, ouch. RIP connecting rod hahaha

so cool to hear and see a RC car making actual gear changes.
I dont know what’s more cool. This whole ass rig. Or the fact that it threw a rod through the pan like a real V8

@@Ni9kyethe power to the plugs is only on during start up, once running they stay lite but the fuel burning

My man needs a long block build with forged internals and billet parts at this point 🤣🤣
Happy holidays my friend, been here waiting to see if you were going to work on this car before the end of the year. Can't wait to see all of your hard work pay off and see you enjoying this beautiful car. Keep up the awesome work you're doing.
It's a bummer you didn't have footage of the rod coming apart.....exelent build my friend
I can smell those nitro fumes from here!!!! 😅 Awesome job!!!! Bummer on the engine. I guess we get a new video!!!!😅
Honestly it’s a very cool car. With the size of it, 1/4 would be a child power car and 1/3 would be a go kart size! Keep it up, I’ve been watching you for years and hopefully more years to come.
I'll be honest...I mainly watch the videos to hear that satisfying "click" whenever you torque the fasteners!
Impressive machinist! Magnificent build.
Bro you do the most beautiful and amazing job on your machine work and that’s coming from a gun smith who machines guns on the lathe and I thought my stuff was small and tedious - not even a match to what you do
you’re killing it with these videos, can’t wait to see what’s next!
The fact your posting on chrstmass day is dedacation. The best channel ever :)
Oh damn, rest in power V8. May your rebirth be that of the pheonix and astound us all with your glorious power.
bro your vids are so relaxing the asmr of the machines is so good
Ouch, too bad about the engine, but nice work on the transmission. A little tweaking on the brass dogs will probably get it to shift. They're always fairly loose in a MC transmission. Usually the 'pin' side is almost round, rather than elongated, to allow plenty of slack for engagement.😉

Wow! Not everyone has access to a CNC lathe with live tooling! That is awesome! Do you own it?
THE ENGINE UNDER LOAD AND THROTTLE HAS THE SAME SOUND CHARACTERISTICS AS A REAL V8 IT ALSO FAILED LIKE ONE AMAZING VID AS ALWAYS! ❤
Damn, it even threw a tiny rod. That’s hilarious.
Merry Christmas everyone, excellent video as always, this year there will be more good projects.....🤗🤗🤗🤗🤗
I would like to see this car on the road shifting gears as soon as possible. PLEASE! lol. Happy Holidays to the Mini Motor GOAT!

The day JohnnyQ90 speaks will be the day he wins the internets.
Will you upload another V12 video of using it to power something? I found that really interesting. Maybe you can set it up as an engine dyno
Very nice attempt J. 👍
finally we see those wheels moving!
You would have to reinforce some parts of the engine so that it is not prone to catastrophic failures since those engines are not designed for such extreme tests. I hope you can soon solve all the problems since I want to see that car in action, it is incredible.
Always fantastic builds, regarding the gearbox, a well timed strobe light may help here :)
It sounds so so good bro keep it up you are doing Amazing work
Never thought I'd see a tiny v8 throw a row.
You are a genius! Congratulations!
It’s time you machine your own engine
May the mill be with you my son
Wow, even the catastrophic failure was realistic! 😛

Also bloody brilliant work my friend I genuinely appreciate the work you put in.. your machining is solid man solid as a 🪨
Im impressed with carnage. Rod release is a good one
I use ATF oil on my nitro engines when not using them a long time, works quite well. Never had any bearing issues.
Merry Christmas to you and the youtube fam!

aww man gotta fix it
that sucks

FINALLY DITCHING THOSE PLASTIC PARTS!!!
TOLD YA THEY WOULD EXPLODE!!!
GLAD TO SEE YOU DOING THE RIGHT THING!!! 👍
I'd like to hear that little engine with X pipe on exhaust. I know there's not much space, but that could be cool :)
That roller bed you made would be ideal for simple dyno.
Amazing work
Cool vid, with sad ending, in germany we call it "einen kapitalen Motorschaden"
Awesome builds, that rear right wheel/tyre is out of balance? Ouch😢on the engine 😅
vraiment très bien! (Very good)
je suis Français et je n'ai pas encore le meme niveau que toi...(I'm French and I don't yet have the same level as you...)
thats a sign that is time to got turbo or supercharged hahah, awesome content, I really like watching your videos
Awesome work keep it up man always looking forward to new mods and builds 🤟
Good lord my ears never heard such harmonious mini v8 iml.
Precision is artwork
I’m super excited to see what you have in store for us next year
The gearbox evolution is amazing, and I assume… based on certain events… that we might be seeing some custom internals soon.
Btw, at what point would transmission fluid of some sort become effective?

What gets me about these engines is. They can range anywhere between 1,000 and 6000 each when he gets a new one he opens it up and runs it right out of the box which usually results in terrible performance and something being broken.

i agree witht he diag and commend you on that engine destruction. Blown like a true car enthusiast. at least you have a inspection port!
You should put knurling on the rollers for better wheel grip
Keep going we will be supporting🎉🎉
