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

[@stuff3219]

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]

Sweet

[@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. I'd prefer to see alloy wheels too rather than plastic but . . .

Also trying to seal weld metal tuding with a continuous weld the tubing will get too hot causing weld blowout. Just by leaving about 3mm unwelded on the weld joint, let cool to ambient temperature fill hole. This way there's no need for drilling hole that you'll may want to fill later

[@BCzepa]

@@KevinTalbotTV in regards to the welding question: cool video. im only 4:21 into it. i know this might be a silly question to ask but: have you been grinding your tungsten AROUND the tip, or along it? you want to grind along it, and grind with something that hasnt touched any iron. the side of a grinding wheel, a stainless steel grinding disk that hasnt been used on anything other than your tungsten, also your gas flow needs to stay on for a good 1-2 seconds after finishing. im sure you know these basics. it could be your gas, maybe a bad bottle and you cant use argosheild, has to be argon. im no pro mig welder but i am a qualified boilermaker.

[@BCzepa]

lol oops, i meant im no pro tig welder. anyone can mig weld XD

[@walooo]

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

[@Garf2O]

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.

[@c-dawg2145]

High durometer usually means less grip, which would be an engineering challenge.

[@biggestcomplainer]

[@MrPetethemachine]

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. Your channel rules.

[@KevinTalbotTV]

Thanks for the tips!

[@bansheebiker]

@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.

[@BagpipekilR]

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.

[@scottiboi828]

[@roanoconnor98]

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!

Hopefully Project Air can get some sponsors so he can keep on building. Such a cool thing to see. I cannot understand how there isn't a reliable tire out there for these speed runs. Surely there is a rocket surgeon out there who could design something that would hod up.

[@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

[@johndoe920]

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...

[@therealsyxx]

Jesus christ what have i clicked on? For someone who has only driven a car that was about 33 mph this is a whole other level of RC racing and speed. I'm just getting back into the hobby with my grand daughter. Ive realized she has a thing for RC cars. She plays with hers so much I'm constantly running out of batteries. about 4 a day and she's only 3 years old. So i think this is the perfect time to introduce her and reintroduce myself into the world of RC cars. And by the looks of this video i have lots to learn. This hobby is huge in the UK it seems. Not as big in the U.S. but thats just one of our many flaws. 😂

[@hazepheno925]

Welding: Your Argon cylinder looks like it is just about empty based on the tank regulator. Many people run their tanks down until they get porosity, and that's when they know it's time to change bottles. Regulators/flow meters need a minimum amount of pressure to work properly

[@reedhill8249]

For welding I would suggest looking at a different cup! A weldporn FUPA number 12 cup will never lead you astray! I’ve used one for over 5 years and it can do anything and everything it also can use the same amount of gas flow as a smaller on but you get way more gas coverage. That’s my suggestion

[@wildbreak7301]

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.

That’s not his problem. The gas cup is leaking. Pumping argon in the tube is to shield the weld on the inside.

There’s no cameras down track as RC cars hitting a tripod or person at 200mph is a bad day for everyone. Also you’re trying to track something small at high speed which is hard enough to properly frame. There’s prolly no drones as they are at an airfield and you typically can’t fly within a few KMs of those… but they could 100% put a dead cat wind muff over the mic to kill the wind sound.

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🤙🏻

[@user-ez9ys4rb6d]

For the welding issue, i would check that you are using the correct settings for the material type and thickness. I would also make sure that your ground clamp has a good connection. If you are using stainless steel, I would recommend taking a grinder and grazing the surfaces you are going to weld to and the surfaces that your ground clamp would connect to. I would also try holding the torch different distances away from the weld, not so far away that you are not getting gas to your weld and not so close that you are dragging the torch through the puddle. The last thing I would try is doing some quick tack welds along the welding surface and turn your power down and build on the tacks. Hope this helps!

[@johnbee1574]

I was trying to work out what was wrong too. the settings look fine amps are quite low but that tungsten is hot "really hot" makes me think hes running positive electrode by mistake. it looks as though there the correct way round though

[@user-hm7rl6jt5i]

This quad motor build is INSANE! I had a couple of ideas for tires. 1st idea is maybe carpet. Like commercial type. It would be like a stiffer foam but a woven design. May not come apart. 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. You have to get it to it's full potential! Can't wait to see how much more it has in it!

[@dextermorgan1]

Watching this I couldn't help but be surprised nobody has engendered a better tire. It looks like the hobby definitely has the followers.

[@Shawnsboostedgarage]

I know you mentioned using aluminum wheels wasn’t possible but if you had the machinist add a knurl to the aluminum wheel to act as the tread then maybe that would work for you. Another idea would be to bond some rubber to the knurled surface. The knurl would give the rubber and glue something to bite to.

hey mate boilermaker from australia who loves rc cars. your tungsten needs to be sticking out alot less, will help the gas properly shield it from the atmosphere during the arc, so just push the tungsten in to its sticking out about 5mm from the shroud and turn gas up a little bit more. you will see a difference and start there.

Rubber Capped Tires.. This is what we used to run on 1/10 pan car oval racing. Early prototypes were just bicycle inter tube sections glued over trued down foam tires. Then the rubber is trued down and scuffed for traction. Later, companies like TRC started to mass produce them.

[@H3110NU]

[@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.

[@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.

I'm thinking about your wheel/tire problem. Have you thought about using taller tires? That would lower the wheel rpm and scrub off some of the centrifugal force on the tires. In the 80's, we used tires that had large diameter heat shrink tubing around the foam called "caps". You might consider using a heavy grade of heat shrink tubing to make an extra tread on your tires. There's even a grade of heat shrink with adhesive on the ID that melts as you heat it up. Can't wait to see you break the record with this. Awesome!

[@kenselleck2414]

Aluminium wheels with holes that are larger on the inside and use windshield urethane for the tyres making sure the urethane goes through the wheel. The funnel shaped holes will anchor the urethane in place. It should have very good traction. Wrapping the wheel with stainless steel safety wire in the urethane will keep them from blowing off the wheel.

[@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.

​@@KevinTalbotTV epoxy sticks very well to aluminum. You just have to prep the aluminum by using acetone or denatured alcohol and sand to 80 grit then apply your epoxy. It gives an amazing bond that is highly heat resistant. So, the foam itself will break down long before the hold of the epoxy.

@@KevinTalbotTV texture the surface a little & JB Weld will do fine. Or use an aluminum mesh tube as the 'tire' itself (if traction is too low, try coating it in truck bed liner or some kind of durable rubber/adhesive)

Damn!! Just seeing these cars at speed is increadible! And to see 210mph! What about 222mph as the World record? You guys just keep it up and go for the gold!

[@BASENTRIM333]

Before welding, flood the tube with Argon . When sealing a tube, the air inside expands and tries to come out through the weld. Try drilling a small hole in the tube to let the air escape as it heats up. If you can't find any leaks, try a different bottle and new tungsten. A brand new bottle of contaminated gas is possible, it will drive you mad.

[@myurcek05]

Hey Kevin, Just create a carrier bearing instead of the block. Run the long solid shaft but just support it in the middle with a bearing the size of the shaft to remove the deflection.

[@BobBasshead]

This has got to be your greatest video to date! Congratulations to all the record setters!

[@tipperz]

Kev you should really look into rubber bonding as a tyre option, there’s a reason why the rubber stays in all the bushes that are on your cars/monster truck and that reason is that they are bonded to the metal

[@Craigsutton1976]

For the welding do you have a vent hole in the tube somewhere? If you do not then the air inside heats and causes pressure that vents out from the inside and causes porosity in the last bit of the welds. I am guessing from what I am seeing in the video clips.

[@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

[@joshanderson1019]

Kev, I think your tire issue could be easily solved if you just go with taller tires and gear it down a bit. Slowing down the drivetrain will be easier on bearings and driveshafts, and better efficiency, while the tires are spinning slower.

[@procatprocat9647]

Incorrect. The surface speed of the tire is the ground speed, irrespective of gearing. Taller tires will increase the centrifugal force and generate more tire blowouts. Lightweight, small diameter and higher strength are the answers

[@bracky02]

Hey Kev, you do a great job, ive learnt alot from you so thanks heaps mate 👍

[@retdreams661]

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.

[@woodytheskip1718]

Just throwing an idea out there. I know lots of roller coasters use polyurethane rubber wheels as do longboards and street luges. Would it be possible to adapt skateboard wheels and use them on the sausage and if so do you think they would survive 200mph+???

[@andy0175]

Brilliant idea if traction weren't an issue...they have no grip!

[@woodytheskip1718]

@@andy0175 as someone who still enjoys inline skating in my late 40s, I will agree that the hard wheels supplied with many cheap production roller skates/skateboards would be next to useless. But some of the better quality ones with a lower durometer, around 76a or lower have plenty of grip. I’m certainly not saying with any certainty that it’s the perfect answer. I know the softer the rubber, the faster they wear out and two part wheels with a solid core and softer poly tread at those speeds it’s an unknown how well they will hold together. But it’s got to be worth experimenting with.

What an awesome build. It might be worth building a rolling road tyre tester, to see what the best option truly is! Look forward to seeing the future for this one!

[@MrBigboy1057]

A single tire tester using an angle grinder would work.

[@roanoconnor98]

@@smnkm4ehfer he could just make one using the same motors. Gear them higher so they spin faster than the wheels would. Just to get an idea for wobble, expanding etc

Tip: put washers under the rivets on the inside if you work on soft materials. Gives lots of strength and better riveting.

Kevin try and clean out the welding handle. I feel it’s the pipe that protects all the internal parts. The other idea I think is try and turn your welding speed up ok hopefully that helps you.

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

[@bloodyknuckles9181]

I think a solid wheel would be the way to go, maybe a soft compound skateboard or rollerblade wheel with a hex pressed into one of the bearing sides, if it would grip enough though would be another thing 😀

[@rustler08]

They don't grip worth a damn unless you have sufficient weight, and that's not going to be enough

[@BrokenOpus]

Is it against the rules to have larger diameter wheels?

[@bloodyknuckles9181]

@@BrokenOpus I doubt it as its rc not f1, the problem is not with the size of the wheels they have its the compound as centrifugal force at that speed is throwing the tread off hence why the outside if the wheel seems to come off worse its not the road cutting into it

[@BrokenOpus]

@@bloodyknuckles9181 why I ask is would not a larger wheel rim lessen that force, as the wheel can rotate a bit slower on the tire edge to reach the same speeds.

[@bloodyknuckles9181]

@@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

Not many speed runners think to use narrow wheels. Glad someone else thinks like I and all the salt flats guys do. 🤗

Love your channel and really digging the speed runs. It really looks like tires are the weak point. I'm sitting here in my shop watching The Sausage episode and had a crazy idea. My wife's longboard is hanging in its spot and I notice the wheels. Has anyone tried adapting skateboard wheels for RC speed runs? Super tough and grippy. Might be crazy, but just trying to think outside the box.

Have you thought about making a custom aluminium beadlock to run a rubber tyre? I remember in a previous video you said that the rubber wheels get flung off or turn on the rim, but if clamped down they should stay in place. Real drag cars use beadlocks for this reason. Just a thought, absolutely Love the content

Your welder has leaks in the argon gas lines. I had to use a smoke machine to find the leaks in my welder, but after I fixed all the leaks, it welded great. Try taking the welder apart, and doing a visual inspection, tighten the hose clamps, check for cracked rubber argon lines.

[@MeOneP]

[@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.

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

[@FettBoB83]

Hello Kevin, you have a leaking hose on your welding machine. Change the hose package to test it. Or check for leaks in the hose. Oxygen comes in with your gas.
