How To Build A Sleeper Drift Quad!

[@EdwinOlding]

And after 6 1/2 years of building this channel with Ethan, I finally started learning to weld…

[@kennynelson2269]

Edwin, you're killing it brother keep at it, and you'll be stacking dimes in no time..

[@brickcity9mm896]

Ed it's not you wanting to weld, it's the you're getting older and your inner beast is craving for it

[@brandonrohrer7914]

Love it or hate it, you can't deny how much fun an electric setup can be. The instant torque is so addictive!

[@richardwhitaker4148]

It's the new wave, so embrace it. But tthese things are beast. I got a electric scooter that does 60mph and its insane the torque and range you can get depending on your setup.

[@TheDivisionAgent]

Its great for toys, currently not viable to completely replace internal combination.

[@nathanielscholtens2812]

It's about time, too!

[@drinkmorecocacola]

oddly enough this stuff is the more interesting builds. the monster bike is whatever to me. things like the mini boat and this are what really shines to me.

[@CrimsonRaven]

I would mostly have attributed that to a Will build, before Will left. But yeah I agree!

[@CautelousOne]

What I would love to see is a crop, cut and assemble video of Ethan's welding tips, he's so wholesome. This starts at about 14:00 and he's talking about uphill/downhill and angled welding with different techniques as to welding a thicker material to a thinner and angles about what you hope to achieve, he corrects the 'too fast' and the 'stuck rod' in a positive and encouraging way. This is the essential spirit of a true teacher. There's NO "I'm gonna show you how much better I am" .... It's ALL "I want to HELP YOU to BE better." Humble and wholesome. That 4 minutes of film made me a better welder and I've never even tried welding.

[@nunyabusiness2444]

I worked with robots for years and am currently a lithium battery technical specialist, so take these as you will, but I hope they can possibly help with the monster chopper. If you're having an electrical signal issue, and you're not finding the issue just by stripping the wires, try checking your crimps on your pins. Make sure you're not slightly over shielding, and do a slight pull test to check for suspect loose crimps. Either of those things can give an intermittent issue that comes and goes. The other thing I'd recommend checking out, is your sockets you plug into each other, for loose connections, a shift in a gasket that doesn't allow you to seat properly, a pin that isn't latching into the seat it should lock into, and it'll move as the connection heats up, and vibration can seperate it, or discoloration on those pins. Hopefully this helps you, good luck with figuring out your gremlin.

[@goosenotmaverick1156]

As an automotive guy, this feels like a proper diagnostic direction to take. I suspect you're onto something with the crimps/connections mentioned. Seems like it could even be something as simple as an intermittent grounding issue. They can be easy to fix and hard as hell to find

[@ck1619991]

Continuity check while adjusting the ride height to kind of simulate movement over bumps might assist with locating bad connections also.

[@blackryan5291]

Mod suggestion to this quad: extend the rear axle and put the motor directly there, it will give more space for battery inside the frame and you won't need to worry about chain tension over a pivot.

[@DigitalJedi]

Getting the motor drive sprocket to be in the swing arm pivot might be a better option as it should keep the unsprung weight down.

[@phalanx3803]

@@DigitalJedi that would be a bit to complicated also the motor would be siting close to the pivot so its weight wont have much of an effect. also unsprung weigh is not that big of a deal unless your going for absolute peek performance unsprung weight is not worth chasing. i have a 105 Landcruiser its got the solid front axle unlike the 100 with IFS there is not really a difference in comfort even tho the 105 has a lot more unsprung weight.

[@jimboh.2654]

That would bring more unsprung weigh and overall really bad idea.

[@christiaanventer8183]

@@jimboh.2654 define. How is unsprung weight going to negatively impact performance on a vehicle already over achieving on a fraction of its potential? Moving the motor onto the swing arm means the chain won't need to flex, more weight on the rear tires that isn't under suspension pressure, and introduces longer travel for smoother ride. Electric motors are less succeptable to impact and vibration than ice are since there is just 1 moving part instead of several.

[@x_ph1l]

Carbon Fiber filled PLA is NOT stronger than ordinary PLA!!! It has weaker layer adhesion! However, it is much more wear resistant. I suggest print most of parts that would not be hot from PETg and parts that you need to be near hot stuff from ABS. If you want more impact resistance - print all with ABS. p.s. 3D printed parts are NOT aluminum and they're not injection-molded plastic, so always make them thicker.

[@amcustomfab]

I second this

[@teedjay91]

I would probably go with ASA most of the time on machines that often live under the sun for its UV resistance.

[@tippmannroxs14]

Or step up to something like pa12 or pa6 stronger but more cost per spool .

[@ravencrovax]

​@@tippmannroxs14was just going to say this. Though CF nylon and CFPC filament spools have come down in price a lot recently. Since they are using a Bambu printer, printing PC (esp CFPC) or nylon/CF nylon should be no problem for them.

I did a build very similar to this using an old rusty tao tao quad and a 1800w motor about a year ago. Man I wish I had a plasma table to make parts like that. To call the frame of my quad crooked is an understatement. Kids love it, though.

[@wilderstewart9917]

[@kurdisshop243]

I'm here to tell you I tig weld food grade stainless every night and I use a bench grinder and drill to sharpen all of my tungsten lol awesome build!

[@stephensage9463]

I wish I had someone like you guys teaching my metals class back when I was in highschool. That's a whole lot cooler than the sheet metal tool box they made us all make.

[@cROSSeyed18]

That thing is sick. You guys should make a "builders kit" of all the custom brackets you made, and sell em. So a guy could buy everything and weld it together.

[@kevinsellsit5584]

At 36:00 you said "it is so crazy you can watch the steel melt". I took TIG welding in college and the most important thing I learned is WATCH THE WELD POOL AND LEARN TO MAKE IT DO WHAT YOU WANT. As for tiny high power controllers, there is a limit to how small they can get. That limit is thermal. Some small controllers specify the mass of heatsink they are required to be bolted to. While airflow is great, chunky aluminum in that airflow is ideal.

[@Brandonscode]

18:51 It literally sounds like an angry kitten 😂

[@Not_A_Cat]

💯% agree

[@spuldup]

How did I miss this one? Great to see Edwin out there ripping in something cool! Fun tip: In 3D printed parts, the direction of the layers determines the directional strength. The weakest bond is between layer lines, where your part failed. You can rotate the part in the slicer to print vertically or a 45° angle. This often uses more support material. Also, wall layers are stronger than infill, so just increasing part thickness (or actual infill percentage) does little to add strength. As much as y'all rip on stuff, use at least 6 wall loops and use ABS,ASA, nylon, other engineering material since your printer can print all of that.

[@skimpp8257]

The POV of you driving that thing looks nuts, it’s like one of those fpv drones

Ethan, I went to welding school. We used bench grinders for the tungstens. Just, a specific one dedicated to tungsten grinding to avoid contamination.

[@Skwisgar2322]

As those of us in the 3D printed pew-pew community have learned, carbon fiber PLA is actually generally weaker than normal PLA. For something like that, you might want glass fiber reinforced ABS or Nylon.

[@gunningdesign]

For 3d printing: use cubic infill and at least 6 walls, as well as top and bottom for structural parts... Preferably more walls. Cubic infill makes tetrahedral shapes which help disipate forces from any direction to the walls and top and bottom. The wall loops make more difference than the infill apparently. Also, avoid sharp corners that's where cracks start. (this is why airplane windows are not square)

Check the infill settings and ramp them up, also small fillets in the design instead of any 90's inside or out. And close the door to the printer, the heat inside being stable and warm helps with layer adhesion. Love the build!!!

Sad that it was Wills project, I miss him in the videos. And the fact he’s never shown in the cuts of the flashbacks, seems like a f-you to Will

[@goosenotmaverick1156]

It would also feel wrong to monetize and profit off his image when he's no longer part of the group. So I can see both sides. It seems to me a bit more respectful to refrain from using his image for profits. Using clips may actually result in having to share profits with him when he's no longer investing time into creating with them. So there could be way more behind it than "f you to Will"

As much as dirt road rally style racing will always win my heart, that bit at the end where you're doing figure-8s in the garage, makes me really think you guys need a flat tarmac track, to take all the micro machines out on with slicks and race like a real mini-F1 circuit.

[@TwistedAddictionSBC]

Great video guys. I recommend getting a smooth bore nozzle for your 2 1/2. That will give you a lot more penetration. The combination nozzle you have is great but it breaks the stream up a bunch even on straight stream. The smooth bore will do some serious damage. I have blown holes in the side of houses with one. Also when holding the nozzle, hold it further out in front of you and use big core muscles to hold the hose vs your hands, arm etc. This will give you a bunch more control. Can't wait to see the next video.

[@pwnsh4rk6]

This is one of those builds I actually feel like I could do myself with almost zero experience, minus welding the motor brackets - and even that I feel like I could learn with the right access to tools. I was almost going to say this should be labeled as a How To video xD

You guys could 3d print some sick looking farrings or some fenders, a number plate on the front, some bash guards for your hands, a cover for the Motor, a chain guard, but yea some body panels with some aggressive angles and lines and actually a vent to draw air to the controller would be really helpful.

[@akabounty-rf4dl]

Something I’ve learned about lenses and carbon build up is if you cover it in a very very thin layer of petroleum jelly or anything clear and equivalent and wipe off the excess you can on the lens and you won’t get almost any carbon build up and if you do you just wipe off the petroleum jelly with a micro fiber cloth and ur all good, remember less is more with camera lens
