As soon as you showed the drift sleeve, I instantly said “drift” - I used to do RC drifting with 1/10 scale thanks to some South African mates who stuck PVC on the wheels. I was instantly hooked! This was back in 2007! Congrats on this awesome build!

Hi, Matt. I love the build, and it looks like it's going very well. I'm excited to see what you do with it next.

[@GENERALWA5TE]

That's awesome, you should see if you can take it to your nearest go kart track to drift round.

[@MattDenton]

Yeah that would be great 👍

[@lifeofmattmel]

Love the split axle. Been thinking of making a electric kart and using a similar setup to my electric skateboard.

[@MattDenton]

Yeah it now turns!! Well :)

[@metagoat]

Awesome stuff. Looks like a blast. My favorite thing is the giant Lego tires. My nephew is only a year old but I have similar "don't tell your mum" plans for empty car parks...

[@MattDenton]

😆 perfect! That’s what nephews and nieces are for 😆😬👍

[@999benhonda]

Drifting with drift sleeves is great fun, you can be going fairly slow, yet it feels much faster. I was surprised how well it did with the split axle and limited steering angle. A solid axle and greater steering angle could allow for steeper drift angles and longer drifts. I don't know the outer diameter of the lego tires, but drift trikes use PVC sewer pipe on a rubber tire. I'm not sure how you'd attach it to the lego tire, or if it would work best just to print some new tires that will fit snugly into PVC pipe and glue the pipe to the printed wheels but the PVC sewer pipe is really thick and will last a good long time on a kart like that.

[@MattDenton]

Yeah it would be interesting to try the solid axle again

[@samuel97silva]

[@ryanm.191]

A Lego 3d printed go kart is such a cool idea… I’m almost tempted to buy a 3d printer now to make one myself

[@MattDenton]

Do it 🤙

[@Hellsong89]

Its really helpful tool to prototype and create fixes but as its said million times there is learning curve and its not push of a button to make it. Printing something that large on even printer that is setup on speed like mine will take days upon days and i would never leave printer going at it on its own so it needs to supervised during that print, just in case of the fire hazard. But yeah get one and start learning. Other option is to get into machining but that is more expensive, but gets you more durable parts and material is cheaply available if you just dumpster dive on right places :D For good price to quality printer i suggest prusa i3 clone its around 300 and gets you going. If you want to make large parts then maybe look into vulcanus or something large like that or build it your self, least then you learn everything about the printer since you built it. Essentially you can just clone i3 clone and make it larger.

[@MattDenton]

Well said

[@ryanm.191]

@@Hellsong89 I’m actually rather well versed in 3d printing, just don’t own one myself. The ones I have access to belong to my uni or friends. I’ve been considering the Ender 3 pro for a while, nice big bed and decent accuracy. Just need a grand project to give me the kick to buy it

[@ErikS-]

I am amazed that the tires even have grip. Since they are fully plastic, I would assume them to slip like crazy.

[@MattDenton]

Yeah not bad considering

[@danriehl4244]

Hacksmith made Mario kart-esque speed boosts with a color sensor. Perhaps you could do that? Alternatively, go for a more LEGO "power up" and try to attach some projectile launchers? There are the Minifig stud launchers, some 2x2 round tile launching 2x4 bricks, and a "rocket" that looks like a technic half-pin-with-stud has a bar rammed in it. I doubt a large version would actually work with tension and friction as the tiny ones do, but it's nothing some springs couldn't fix lol

[@sambrown6426]

Maybe you could add a 2-speed transmission. I don't expect you to shift it while moving, but being able to choose between a lower gear for better acceleration and electronic braking (When you fix that.) and a higher gear for a higher top speed could be pretty cool.

[@MattDenton]

Yeah that could be tricky 🤔 how about just bigger motors 😆😬

[@sambrown6426]

@@MattDenton That would be cool, but bigger motors tend to draw more power, so you might need bigger batteries, heavier gauge wire, and beefier electronics to handle that. And if I'm being honest, I didn't expect you to actually do it, I was just making a neat suggestion.

@@MattDenton you are on the old Winchester to Didcot route.

did your nephew take professional drifting lessons or something? because that looked quite impressive when also considering how difficult a skill it can be to master. (at least in normal full sized vehicles anyhow) other thing i was hoping to see would have been to remove 1 pair of the covers. so that only half the total width of those double wide wheels was covered up. to give a bit more traction. however we didnt end up seeing that in this video. oh well nevermind. not at all sure if it would have helped or hindered, just kindda curious
