What form of expansion are you thinking about? Radial? If you mean the width. Then I can’t see why it would ever be a problem. They are spinning the same direction. Now radially. I could maybe see that as a problem. But it could be adjusted out so the tolerance would be right once they are at running temp. Would just be a little loud while warming up the first few runns
@@Mad.Man.Marine axial expansion towards each other, I know for a fact those motors do not use thrust bearings and only have two radial ball bearings on the shaft which cannot handle axial loads. The shafts and the gears will expand with heat. It will at minimum create extra drag and convert wattage into heat. Long term it will ruin the bearings in the motors. To deal with this he could use a captured one piece pinion with needle thrust bearings for each pair of motors that floats on the shafts with no set screws and would allow for expansion. This may seem over engineered but I can't help it, I work with bearing tribology, and industrial rotating equipment reliability every day lol.

Im looking at this already and chassis flex will be changing your mesh dynamically. I would say put another carbon plate to stiffen everything above the motors as well, like a brace. It will help immensely
You're always going to be fighting flex, he really needs to pause and redesign the motor mount assembly to be monolithic. That's the only way you're going to get the required stiffness out of it..
Looks good but I have doubts. Those gears will be stripped due to the power and the tiny area of contact. Personally I would turn around the motors and use 2 spools this will give you 4 times the surface area for the pinions and much less stress on the now doubled spool gears. Hope it works out for you, all the best.
@@markmmm1737 steel gears, 5mm engagement on either side, properly meshed, it's gonna be fine "Stock" really doesn't say much, could be plastic or aluminium gears, not meshed correctly, heck, even the wrong type of steel could be reason enough ever see a 4.6 bolt? gonna strip long before it's tight
Would you be able to have 2 motors run the left drivetrain and 2 on right? I don't know hardly anything about electric RC's. I take it with programming, the 2 sides could the trimmed to match power???
Really really impressive, I have to think the middle drive gear is going to get beat on pretty badly. Having some form of mechanical slip clutch in that center gear may save it and still transfer the power.
Raz - the machining and workmanship is absolutely top-notch! You are probably learning so much from this type of extreme build that many 'makers' would never get the experience to learn because of the sheer problems surrounding the power transfer alone. That doesn't even account for trying to keep everything inside of the car's footprint and map out where the parts need to go to make it work. Bravo on an amazing build.
Everyone is speculating about what is going to fail in the drivetrain. I am confident Raz will find the weak link on the first outing. Keep pushing the limits, it’s what makes the hobby so much fun.
The music at the beginning is awesome and suits the video completely. Celebrate the quadness and the machining of the pinions on some classic machines.
Always taking it to the next level Raz, this is awesome! I’m sure this put a smile on your face when everything fitted so neatly, with such fine tolerances 👏👏👏👏
Top noch build as usual, but man, editing is at the same level if not better. The first part of the video and the conversation with the machinist is awesome 😝😝😝, you made my day. Keep pushing Raz!
Man you do the most epic builds Raz. I’ve just done my first scorched infraction chassis , Raz carbon shafts , all the other carbon goodies and it’s all thanks to you and some of your tutorials vids. Thanks heaps.
@@keithbranch7718 right! When I build a rc I honestly try to build them like Raz super clean top quality go fast parts and less is more sometimes.

That thing has same power to weight ratio as a Honda civic with space shuttle rockets and boosters on it crazzy as hell man. That much power 60 hp you could literally put all 4 on a racing go kart and have a fast 60 hp electric beast it's possible I saw a guy on RUclips put two giant brushless mamba biggest motors they make on his go kart and he hit 62 mph at 80 percent throttle he turned it up to 140 percent on his radio and it went 78 mph with out him on it testing with him on it he did 68 mph at 140 percent throttle rate on his transmitter. He uses just the transmitter for throttle everything else works like a reg go kart
Raz, please read this. Coming from a mechanical engineer perspective this construction is destructive, you cannot mount two motors that are connected directly to the same gear (and you are trying to connect 4). You must have some sort of an interface between them. Best case scenario a reverse differential, worse case a torque dampening coupling on every motor shaft. You absolutely must do that because the motors don't turn continuously, the poles of each motor always allign differently, therefore the motors experience torque ripples. In this case the torque ripples are rigidly transmitted to other motors which create motion interference, that's why the car sound bad in your newer videos. Motion interference leads to loss of efficiency and destructive forces on the motor and gearbox. I have experienced this on full size electric vehicles, believe me, this phenomenon can split gearboxes open. As I have mentioned, to avoid destruction and to get better results, you must install a differential or couplings.
Idk why but I always feel like these dudes mechanical knowledge is limited to rc level , and I swear to god you meet the dumbest and uncreative people in this hobby.
driving down the road and never let your eyes off the gears, some priceless video. that editing was gold. oh yeah, I got a question. I know this sounds a bit excessive, but, are you going to clock those motors, so they're exactly in phase, considering that they're hard locked to each other (no clutches, slippers, etc.)?
That was pretty cool. I was a machinist when I was younger, so that's all very familiar to me. Ughughughugh! Looking forward to more of this car. Wonderful parts from Scorched btw. I reckon that you might have problems with that set up, the pinions and shaft gear. Happy to be wrong though.
Nice build. But don't you think that the pinion on the main shaft is way to thin? And the pinions on the motors need some work also. Whit this pinions you are grinding the main pinion apart!
Hi Raz, this is an insane build, loving it so far. Can you get custom pinions with 2 spigots so both facing motors use the same pinion gear, this will guarantee matched timing.
@@krisallen6466 it will work, no doubt. But it is more about longevity/lasting. This car will likely run at short bursts anyway... 60hp,lots of torque. When it goes wrong it is likely a spectacle :-) Either way it will run.
When talking about gear mesh, there is a small amount of tolerance allowed when setting the motors in place, however there is way less tolerance when attaching two shafts like that. Since they are rotating, any misalignment will cause an insane amount of stress on the components involved and most likely break something or loosen screws at a very fast pace.
Omg😮😯 those scorched RC parts look absolutely beautiful. I have lots of questions about this already but I don't want to bother you too much with them. This is exciting, can't wait to see the next video. ❤️ Sending you love from France 🇫🇷
It's just theoretical peak power. If they are 12s capable motors and can handle 250A peaks they will hit those numbers. It's actually the cables and connectors that are the limiting factors. 8AWG cable and 8mm bullet connectors should do it.
@@richardmiddleton7770 There are more problems than just the cables in getting to an actual 60 hp in the car. while HP is a product of RPM and torque and theoretically one could push 60 hp through a very small shaft by spinning it insanely fast with very little torque that only works for a motor. when applied to a car that HP needs to be translated to the wheels and there is no way those little drive shafts are handling 60 hp unless the wheels are spinning so fast the centrifugal force would make them explode.
Yes that would work but then you've sacrificed too much meat of the gears and they'll likely fail after some time bc electric motors have extreme torque so yes get ready to remake these when you should've welded the holes shut then rebored them where ever it was you needed them to be at? But cool Home you got and like the car is pretty Rad too
This is a really cool build for bragging rights but that thing isnt anywhere near 60HP. At best The quad motors are putting out somewhere between 35-40HP collectively. Thats assuming that each of those 1650kV motors on 8S consumes somewhere in the neighborhood of 6500-7500 watts each. Castle doesn't tell us the wattage ratings on their motors but a Hobbywing 1650kV on 6S is rated at 5700W. The really big TPPower motors can get up to around 9000W each so going somewhere in the middle of that (which I think is being a bit generous) at 7500W is only about 40HP. If you calculate for 7000W each then you end up at about 37.5HP total. Once you start taking other factors in to account like voltage sag, efficiency, etc youre probably looking at something closer to 30HP for all 4 motors combined. Id like to know how you arrived at 60HP.
@@trevorlaquale6602 10HP I think is still a stretch because I dont think thats taking things like efficiency, voltage sag, etc in to consideration but that number is at least in line with the upper end of what my HP calculations came out to based on Wattage approximations. Im curious though where you found the 10HP rating at because Castle doesnt list that info on their webpage, or at least not anywhere on the page that has the motor specs. You got a link to where you found that at? Im betting if you could Dyno a single 1650kV motor on 8S it would only dyno at maybe 6-8HP per motor.
Man I have been waiting for this vid and can’t wait for the running vid as well. You are truly a genius and a leader in the rc world. Everyone else is just a follower.💯
Dudes rc car is more powerful than alot of cars from the 50's, and probably more powerful than some in the 70's, that's insane coming from small 4 electric motors.
Wow ! I think only a genetically modded pilot could handle this car ! Ime a bit worried on the center pinion, this poor guy is arrassed by 4 motors, 4 huge pinions that cover over his own conception, I 5hink the center pinion should be just larger ... To have 100% of contact surface for all 4 motor. Ok...you read it? Now we want to see your next video for sure ! 🤓🤓
And if y'all need to add weight with weights to these cars but need to save as much room as possible look at the tungsten weights instead of lead they are a 1/4 of the size as the same mass in lead saved tons of room super small and flat you can put them anywhere even on bottom side of chassis. Also they make lipos that are really flat for rc racing and the connector is 2 holes in battery for bullet connectors to go into and a small hole for your balance port which is a tiny bullet fort charging. You get the best connection possible using bullet connectors batteries with the holes in them
