Damn that thing must be powerful

Interesting!

So, which one is more powerful. The nitro version or the electric version and which one do u like @JohnnyQ90

Insert shocked pikachu face meme here 🤣🤣🤣

I have a question, why didn’t you use rubber tires instead?

This don’t need programming this can be done on the remote so the servo didn’t use it full swing. But prob he don’t want to break speed records and use full swing on the servo

There is a easier way. He removed the 4wd and switched to rwd...

if grooves help with grip, then why do both drag cars and Formula 1 use slicks? :P

tire groove only helps if there is anything to channel out from the surface of the tire. The largest mechanical grip will always come from slick, patternless tires.

You're right. Threads are only needed to avoid hydroplaning on wet roads. Tire threads do infact reduce grip (when compared to slick tires) on dry smooth roads. That was an oversight on my part.

Or you can just buy rubber tires and wheels and skip all the complicated math and physics

@@itchyprince3793 sure you could. But I think if you're building rc cars from scratch, then you're probably going to want to understand how and why the car moves the way that it does. That way, you improve and optimize it. Which is what he asked for.

yeah. buy rubber tires and if the rims are not good or bice enough, 3d print then based on the tires needs.

+1

Foam tires seem to work fine on 1/8 Gas cars and they would be as quick as his car.

@@Rtechmobile the torq difference is huge as electric it is from 0rpm while gas has need of a little rpm meaning tyre has "time" to adjust the inertia

Back when I worked in an RC shop, HPI sold belted rubber tires for just this kind of application. If you're in an experimenting mood, they have different foams for inside each type, but the standard ones should work fine for you. Ofna sells belted road tires too, but last I checked they were only for 1/8 scale buggy wheels.

both easy and viable fixes.

the gyro just sounds like cheating if you havent already tried to tune the car the way it is. only after everything is already as good as it can get in its configuration, then slap a gyro on it. but yeah throttle linearity tuning is a must for any syle of build.

A simple gyro from a helicopter linked to the steering servo and placed at the back of the car will enable she used to do one of two things keep the steering and check so it doesn’t wander out or do it the other way and turn into a drift car that’s really controllable lol at a fick of a switch , and u can buy different compounds rubber tires for track that have a temp Ratings and u can use a tire grip solution that you put on the tire that makes them tacky

darren minter everything you just brought up is what makes this go from an awesome engineering challenge to a cheap boring hack at achieving traction, ill straight up stop watching this series if it ever becomes something like that. we are not recreating and simulating characteristics of a vehicle, we are scaling one down while maintaining all the physics principals and strategy towards achieving traction employed by the real thing.

Solid rear axle and some better tyres and weight distribution 🙌 very thick oil in the front diff. Could lock the rear diff with bluetack or epoxy

Angus Rae damn bro, wtf did he do?

If you go back to his previous video he installed differentials with tuneable slip. I think he would benefit more from a front rear torque split and different gearing. Those shifts are just too much. Even a flywheel would help with those massive jumps in torque.

The wheel exploded pretty sure because of the diff. More lock would have prevented that.

@@fabianrudzewski9027 in what way? Locked diffs put the entire force on whichever tire has the most resistance, in practice this increases the chances of breaking things. A limited slip equalizes torque, which has a limiting effect on the stress each tires recieves. Locked diffs also have much worse handling.

You are definitely right

@@danielrouw2593 Locked diffs don't let a slipping tire speed up compared to the gripping tire though, which would prevent the blow-out. Limited slip is usually the best of both worlds, but at high power scenarios, a locked diff might be the only way to prevent spinning.

Exponential right?

Dude its a 1/10 car the car just need a propper alignment

@@racingrivals8934 he's talking about the exploding tire. But it exploded due to him doing donuts at full throttle. In that case, the open diff spinns one wheel to double the normal topspeed. That way, you can kill almost any tire. Super thick diff oil would have saved the tire

Grp is pretty good and cheaper. Not sure if they do 1/10 as I run larger (infraction)

@@racingrivals8934 an alignment wouldn't be enough in itself, he has a few things to sort out. Tires Alignment Camber Dual rate adjustment to help with over correcting when steering. Tires are the biggest change to any rc, they can be a big upgrade in themselves (other than power upgrades). I had my rustler 2wd up to 140kph on jc concepts tires (non belted) before a tire blew.

@@deathnightANIMATED I'm sure with the 3d printer he can make 17mm hex for the car he has.

I think the biggest traction benefit would come from the suspension, it seemed like it is just so lightweight that the dampening speed and springrate needs to be super soft in order to transfer more of the bumps into the suspension. when it slips into a higher gear with the throttle pinned, the excess energy should be stored in the rear suspension rather than the tire surface which is causing it to break loose. this will help prevent traction loss during launching and shifting under throttle, aero will not really effect launching but could help maintain traction at speed but should not be relied on. you dont really want to add weight or remove power, but shifting weight whenever possible is ideal for minor balance adjustments. and instead of changing engines, you just need to play with the throttle linearity as well as the torque rampup rate. once it gets dialed in, the steering linearity should be modified to reduce the twitchyness of direction change. one last thing, it might be a good idea to put a layer of material under the tire foam to prevent rim damage if the tire blows off again.

Definitely needs rubber tires. The foams are not the optimal option in this situation

EXACTLY 💯. Toe and camber

Would surely take this project to another level, but should swap the body for a truck to fit the arduino :)

@Arthur to fit it where exactly?

Uh yeah no more foams

imu + tuned pid loops

Closed loop arduino? Might be a bit tough especially as different surfaces will require a different type of input.

But hard rubber results in losing traction,right?

@@alphonsjose6812 It does, but having tread rather than being proper slicks should minimise the issue on non-smooth surfaces.

I thought this too but the dowside might be that it's going to pick up stones and ruin the tires

on clean roadways it could work, but anywhere else they would get real dirty real fast

Or just give up with foams and use rubber tires

@@itchyprince3793 there is nothing wrong with foam tires, its the application of the cyanocryciliates used to hold them onto the rims, CA glues are great for ribbed tires or tires with minimal bonding or grooved surfaces, your dealing with a tire now that needs complete surface to surface bonding instead use this list of items needed: rubber cement, mineral spirits, gloves, bowl nose plug lol optional items : mountain bike inner tube and scissors make sure the tire is not bored to the diameter of the rim but leave it as is, make the rim about 10mm larger than the center of the tire, then use contact rubber cement, coat the rim and the inner surface of the tire, let it dry thoroughly do all 4 tires and rims at the same time, this gets a bit messy, when dry take mineral spirits and dunk the tire into it and quickly stretch the tire over the rim, the mineral spirits will soften the contact rubber cement only for a few seconds so be quick about it, once the tire is on the rim let it sit overnight true the tires on the rims once trued you will be good to go, if you want to increase the traction on dusty hard packed surfaces or concrete, then take the inner tube and cut a piece that measures just about 3mm shy of the overall contact surface of your trued foam tires, again repeat the mounting of the above specifications on this time , you will need to fabricate a half cone basically the diameter of the tires after truing, and then coat the contact surface with rubber cement and the inner side of the inner tube, let dry completely, then dunk the inner tube in mineral spirits and use the tire horn to pull tube over the tire making rubber capped tires, I used to race 8th scale BMT's and later on Serpents and this was a standard in onroad high speed racing and helped immensely with traction, the benefit of rubber capping is you can use tire grip additives, the downside you cant true them save that of side wall truing,

@@AUGRaijin wow that is a lot of info

I also suggest adding some weight to it, I know this seems a little counter intuitive as light means fast but too light and you lose control, balance the power to the weight so it stills goes fast and stays on the ground.

He needs to do some more suspension tuning to keep all 4 tires planted

While drifting, you still have a lot of traction..

@@RC-ty5ym Most drift cars don't have the insane torque to weight ratio as this car.

@@ryanwalton986 That might be true, but it's completely senseless to drive the Schumacher touring car out of the video with 2wd...

pointless. it's brushless. learn about how brushless motors make gears obsolete.

@ do you mean gearboxes or gears in general?

Brandless Chinese mini lathe from the looks of it. Likely modified to run within proper spec.

Its an Optimum, I have the same one, with some modifications they are great bench top lathes.

Check out 'This Old Tony' (channel) for his vids on a mini lathe.

Go make one😉

Plenty of kits. You can get rollers you can build up yourself or RTR (ready to runs)

Sorry. But you don't need 1000s in machinist tools to do this. You would be surprised what you can do with basic tools a grinder and a soldering iron. That's where I started.. working up to buying a lathe soon . Please don't knock down anyone's ideas ,passion, or dreams. He might even work at a shop where he might be able to borrow time on equipment.

@@marcialdospuforini1197 why so hostile? Saying to go make one doesn't necessarily mean go machine one from scratch. There's plenty of parts kits to build up your own RC exactly how you like. Ease up buddy.

@@marcialdospuforini1197 Not at all, 3D printing and glue go a really long way. If you need parts that require a lathe just go to machine shop and order the parts, no need to own the machine yourself.
