Regarding the welder, your gas cup is leaking where it seals to the torch, letting air into the argon. A quick fix is tape or make sure the gas cup is tight.

I worked with a friend with a C&C machine. I built a set of alloy wheels that are bead locks. Air filled they have had no issues at 160+ mph. We doubled the center tread and installed small rings inside the tire. After much trial and error, we have figured out a weave that stops any growth of an air filled tire. Anyone in top speed RC knows how hard that is. We've spun the tires on large bench motors to over 300mph, no over expansion, depending or failures. Tires are whats holding back records, not power. Were testing small go cart racing tires as well, very promising.

[@feelincrispy7053]

The argon gas can be very easily blown away in very slight indoor drafts even if you can’t feel it. And even if the argon doesn’t completely blow away the ‘dome’ of argon around the weld can be disrupted allowing air to get in causing the porosity. It seems pretty likely that was your cause for shitty welds considering your welds started coming out better later on out of nowhere

Hi Kevin, I'm a Welder, there could be a number of reasons for the porosity, I'd be checking the o-rings in your torch, especially around the tungsten collet, and also the tail piece, it might even be a crack in the tail piece, another thing to check would be any pin holes in your gas lines. Both from the bottle to the machine, and from the machine to the torch, other than that you could change to another bottle of gas, but rarely is gas ever contaminated. Good luck with your endeavours.

@kevintalbotTV good points above but If your welder works fine for stainless steel but poorly on mild steels it may be your filler metal. Mild steels GTAW benefits from using a filler rod with added silicon and manganese to avoid porosity. It also performs poorly when welded without filler (autogenous) compared to stainless steel for this reason. Try “ER70S” filler rods and see it that helps.

Another wheel idea: High durometer skateboard wheels. You'd need to engineer a connector, but that could then be reused on any off the shelf wheel. They're readily available in diameters that work for rc, and relatively inexpensive. The water jet channel shows them spinning up to around 45k rom before stretching and bursting, which is over 300mph

[@TH3H0LYJ3BUS]

My first thought was going to urethane. They would be heavier but they should stay together at least

Could probably work if you used around 78a durameter longboard wheels with a plastic core to keep the bearings in place, just something slightly softer than the normal 99a wheels so the car can have a bit of grip.

[@TechGorilla1987]

I really think that's why the sand flat cars often run solid metal wheels.

[@supervolant]

Why not use a proper tire compound instead of this porous foam? Its a mystery to me... And like @TechGorilla1987 is mentioning, the real land speed record cars in the higher end all use solid metal wheels. Due to the large diameter and rotational speeds these wheels experience tremedous forces, no rubber can hold that.

[@MidwestFarmToys]

These cars only need simple steel belted rubber tires. It's just a B to make them. Someone would have to set up the cords then impregnate molten rubber around them in a vacuum. The problem will be balancing them. You won't be able to just install them and go. They don't weigh as much as real cars and the speed at the perimeter isn't much higher than normal cars

The 2nd idea is either NP1 or Sikaflex. These are industrial, structural urethane. Basically rubber in a tube. Use dish washer soap and water to tool it. Just thinking outside of the box.

I think the reason for the rear tyres wearing down is because they aren't connected to the front. With the downforce pressure on the front wheels, the rear wheels could be trying to go faster than the fronts, wearing them out and causing them to blow. No idea if that's the case but just a theory!

I've done the math on the tire size question. The centrifugal force that's going to blow the foam out is inversely related to the tire radius, at a given speed. F = speed/radius. So bigger radius tire is undoubtedly better. This is why F1 cars running at 200 don't instantly blow out the tires, despite them being made of rubber. TLDR: Big tires = Faster speed before blowout.

[@ianmangham4570]

[@lorditsprobingtime6668]

Exactly! Bigger diameter wheels, as big as he can manage to fit without having them creating too much drag and as skinny on the front as he can or possibly little mini fairings coming straight down in front of the lower section of them to try and avoid lift.

Im sure you know this already, but you need the center driveshaft. The power and load bias between the two front tires and the two rear tires are killing your foams. If the fronts are spinning slower, they are scrubbing the foams off from the push of the rear. And the rears are wearing exceptionally fast because they are trying to push the slower scrub of the fronts. They need to be synced through the driveline. Great video kev, keep up the hard work and dedication brother! Maybe see if you can get a set of balanced steel belted tires on some trick carbon wheels 😎 or take some fiber core gates coolant hose for semi trucks and glue them to some wheels?

[@JeremyKuhnash]

i was thinking the same, a very interesting piece of kit could be to sync them electronically so that the ESCs are linked to a central controller that monitors the wheel RPM individually and adjusts to suit. Your road car does all sorts of realtime things, the electronics are up to the task believe it or not even at very high speeds.

The poor welding is due to the pipe being closed on both sides. The air in the tube expands due to the heat. And wants to escape. The air escapes through the weld pool of your weld. The solution is to drill a small hole +/- 3 millimeters in your tube. The welds on your exhaust are perfect because the tubes are open.

[@xishootstuffx]

This guy^^^ If I remember right (Disclaimer - brain tumor) the pros pump argon into intercooler pipes when welding them.

you can glue foam to alu perfectly fine with the right glue and roughing up the alu. And it might keep the foam from flying off a bit better because it's gonna flap about a lot less and force that is smoothly introduced is always better than dynamically changing loads. It'd also probably be cheaper because you can reuse the alu wheels and just need to glue new foam to them. Only downside is they're heavier and thus need more run up to get up to speed. Though with that amount of power that shouldn't be a problem and I'd rather be worried about the resistance coming into the drivetrain getting everything hot...

@@BrokenOpus yes that is true however the larger the wheel the more foam it uses which would counteract any benefits, other than a solid wheel it would have to be a steel reinforced rubber tyre like a car, cars have the same issue after 130mph which is why car tyres have speed ratings on them

[@ThePaoligno90]

Just an idea: would it be viable to use supercapacitors instead of those batteries? They hold less energy, but you can recharge them much faster, they wear very little, and they can output a crazy amount of current, useful for short bursts of power like a single speed run.

Im building my own speed sausage based on Kevin’s design. The speed to beat at my local track is 160 so I believe if I can control the thing, I might have a chance. I already crashed it once though

[@watchmarley9268]

So which part of the video did he go 250mph?

[@Kassore123]

he was joking in the thumbnail

[@TikaSubedi-sr4jp]

What?!?!?!

[@MudRun-sc2cm]

"Linatex" rubber, we use it in our mining circuits, hard wearing, light & like a dense foam but lasts for ages.... worth a look maybe?

[@casuion8895]

good job Kevin, hope u gonna break the World Record :)

[@teksrcs3464]

Hello Kevin, I appreciate your videos. With your welding issues, I assume that you are using argon gas as a shield, as for the filler wire, use Stainless Steel filler wire on steel thinner than 3mm/1/8 of an inch. That was an awesome video, those cars are super quick, you all do well to keep them running straight. Thanks for your input into the RC hobby.

[@wolfparty4234]

I don’t think he was running a argon bled gas while welding the flat mild steel to the SS steel tube.

[@teksrcs3464]

Yeah, not sure, I will ask him.

[@scottnation5685]

I really love the craftsmanship and engineering that goes in to making these cars.

Hey there kev! Welder here as well, I'm not too sure if I might be way too late someone may have mentioned it but I have had that kind of issue caused by a bad ground as well🤙🏻

[@ab_railways_original]

With these tires. It may be worth scoring lines into the plastic tires, then when the foam comes off it still gets some grip. It also ma be worth installing some sort of tracking system so it finds a line and sticks to it. Excellent video as normal . Keep up the good work

[@billmadison2032]

I really love how you highlight the normal guy and kid. Very good job Kevin they're the future.

[@nicholasterzidis8968]

For the foam ripping off at high speed you could make the wheels taller as this would increase the foam’s distance from the center of the wheels thus decreasing centripetal force. This would allow you to keep foam for grip and achieve a higher speed before the foam rips off.

[@GamezGuru1]

wrong way round, this would be even worse!

[@Steve-hd2wm]

Kev, have a look at an ice hockey Puck. Very solid rubber material. Get one in the lathe and turn yourself a set of wheels. Nothing to de laminate, very solid may hold up at speed and not destort if you stay on the narrow idea, maybe possible to bolt some ally disks through the turned Puck to stifen it up. Just an idea mate. Love some feed back if you give it a look. All the best with smashing and holding the record in the future. 👍

[@WildhurstLodge]

You need hockey pucks for wheels! Just drill a hole in it. They won’t come apart, good weight, no glue, and they have some grip texture on the outer edge to grip the stick. I think they will make perfect speed tires.

[@wibbledee]

Those welds on the headers were impressive, it's definitely not a technique problem!

[@saltysteel3996]

Someone needs to make belted high speed tires for RC vehicles.

[@jstewart627]

20:16 we need a full examination of those wheels in that shot, and the wheel cover.

[@TheSamurai0622]

Try 100percent argon if your not already. By the looks of it your tungsten is contaminated and not ground to a nice point. I would also get a gas lense kit for your torch size. If you weld any metal that is coated or dirty it will cause issues and more than likely contaminate your tungsten. Which will need to be cleaned up to work properly again. Make sure you have the right grade of tungsten as well. Stick out length of the tungsten is also important, if it's out too far the gas will not protect it. You get way better coverage with a gas lense kit and can therefore use more sitckout. Double check all you settings including post-flow to make sure they are right and if you are not using post flow you are contaminating the tungsten. Post flow needs to last until the red hot tungsten is cooled.

[@nickkoepplinger9204]

Dude i loved the event but Noah's mom is a Hottie all the way

[@tyger1st]

Also add a downward air dam at the front and vent behind the front wheels to keep them on the ground. Oh, and good luck!

[@abgaming8607]

Kev, due to galvanized iron coating on the metal pipe, we can't weld it properly. U have to grind or rub with sand paper on the place which u r going weld. So that the tungsten rod will not melt and no porosity will come, love ur work man❤❤❤❤

[@monsterbuzz4105]

To fix the center wobble, could you fit the shaft in a barring and make a custom mount in the center of the car?

[@burgerjointgame]

Been watching since the start, congrats! Must admit I thought this long chassis would sag, but happy to have been proven wrong!

[@Liveforwhatyougive]

Man those skate park bashes are brutal. Rebuilds the truck, immediately brings it to the skate park 😂👍🤟! Love the channel Kev, super addictive. This is really getting me inspired to get back into rc again.

[@abel2088]

You would think that theres a company that makes rubber tires for these types of RC cars .. All in all great video!

[@boothby18]

Kevin just wanted to say the video was awesome thank you! And the part about Andy's proud dad club hat was hilarious!!! 🤣🤣🤣

[@PilotAlphaKilo]

you guys should get an fpv race drone pilot out there to chase the cars. they could easily keep up with the cars. if you ever wanna fly me out from the states id love to do some filming for free!

[@Mike-hr6jz]

Rivets create drag if you want the tires to hold up, you take carbon fiber, thread, and when forming the tire, you put it in the rubber like a steel radial tire. It will not blow apart this way.

[@gotez7gaming748]

that hing has more horse power than my car

Very nice!

[@gyateste6191]

Should call it for what it is.. It went 190 mph ,before the car exploded.

[@onestopfabshop3224]

That little tire lathe you have there is quite remarkable. Never seen anything like it. But then, this is my first time to your channel. I do the RC planes, I have a 48 foot trailer full. I think i have like 26 planes in different stages. Full unbuilt kits, ARF Kits, ready to go planes and of course, a few crashed ones. Lol Your cars go faster than my planes! Lol Oh mine are all nitro and gas, i have no electric ones.

[@Freezedriedmage]

Kevin, what gas composition are you running? Mig and tig gas are not the same. The most common MIG gas is 75/25 75% argon 25% co2. Tig will weld horribly with that gas composition because the only gas you can run with TIG is pure argon. Also with Tig cleanliness is key. You should be cutting the part then following with a hand sand around and on the weld to remove any coatings followed by a wipe down with acetone to remove any oils. Another thing you want a nicely ground tungsten tip. The sharper the angle of the grind the more pin point the arc but the faster the tungsten balls up under load. You should also be welding in reverse polarity. Any questions hmu.

[@rightsidelanechoice7702]

For starters, there. You paint the body on the inside of the clear body so the paint doesn’t get thrashed

[@wolfparty4234]

Top fuel dragsters run over 300+ mph. When they broke the 350 mph they were running harder compound rubber tires. What if the foam on the wheels were harder. Maybe try a sold hard rubber wheel and tire combo. Aluminum wheels will need a hard rubber compound for the tire

[@wsbill14224]

I have an idea. Get aluminum wheels and make tires by neatly cutting strips of inner tube and super glue it to the aluminum wheels. Good luck and go fast!

[@red6standingby221]

Not gonna lie, only clicked this video because you look like Rhys Darby. Good luck with the cars Murray.
