I'm glad you are at the pod and giving it the recognition it deserves, if you live in the UK and you have never been, i 100 % recommend it, it's 100 % family orientated, it's an experience you'll never forget, just don't forget your ear defenders,
Do forget ear defenders, it’s loud but that’s the experience
I have always loved drag racing, I grew up around it. I even travelled with NHRA for about 5 years. And I will never stop loving drag racing.
Maybe the diff blow was due to the sticky part of the road, all that 100hp was put through the diff as the wheels were locked to the road from the sticky road, maybe usually the wheels spin up a bit on normal tarmac and takes strain off the diff.
love the vids!
Yea I agree, far too much traction for the drivetrain to handle with all that power. Rolling start for next time Kev :)
I am almost 100% sure that the problem was too much traction, all the power suddenly went to the drive shaft which simply couldn't handle it. Under normal conditions, the wheels would spin and the power from the engines would be distributed. It's one thing to withstand the power transmission at high speed, and another thing to withstand the power at the start, especially from the electric motor which provides full torque from the very beginning.
The cause of the car jumping is also too much grip, this is what a wheel behaves when it has too much grip.
If you want to try aluminum wheels, have the surface of the aluminum prepared with a knurling tool at the machine shop. However, I think I have a better idea. At work, we use a lot of urethane and epoxy for casting, and they are quite impressive. You could have an aluminum wheel machined with channels through the diameter of the wheels, then cast urethane around the wheel. This way, the tire would be mechanically locked to the wheel.
He wont respond to logics like this , dude is not to bright with physics .
So what if he isn’t into that he probably knows stuff about rc’s than you ever will
I get the feeling you're going to run into ballooning issues there, and I think, especially with how often the current tires are being completely destroyed, it's not going to be cost effective, I think the current technology needs to be refined and I think we need to stick with plastic wheels but design them so that their structure accounts for the crazy forces that their experiencing.
How about aluminum wheels with spikes? Milled from solid
Very short spikes, so that he only gets good grip
Clicked to see the rc but stayed for the real power. That was fantastic.
Been watching this project since the start. Hope you get a record! Good luck Kev!
Kev, I was thinking you guys should run mini drag chutes. Would save everyone!
Its 420am here in New York and kev drops a video, great stuff can't wait to how it goes. much love and respect brother!
Yeah, it is always 420 somewhere😆
@@freedom8480Sounds good but you must be high if you believe that true. 😂
I’m here in New York too but it’s not 4:20am for me, it’s 4:45am for me.🤷🏻♂️😊
@@peteroman4297true it's not 420 anymore, unfortunately it was only 420 for about a minute when I typed my comment lol 😂
Yup, ny here too. Had to see it before sleep 😂
Here in the states we use aluminium rims with proper (albeit tiny) steel belt tyres. They are filled with foam but its the only way to keep things from exploding like that.
7:05 "whats goen on?!"😂❤
My uncles got a 1500-2000hp suppercharged outlaw car. It's awesome only thing is the motors don't stay together. 😂 fastest she has ran is a 6.90 on the "big engine" winsor and runs 7.36's with the clevo. I absolutely love working on it. Hasn't been together for 7 months becuse we have been waiting on piston sleeves and after that pistons then measure gaps and put it together
Another maybe tip.... Throttle extension. So you can more gently and precisely apply throttle. That will help with human error shock to tires and drive train.
I think you are pretty on point at what happened when you lost drive. The dragstrip is so sticky that when the car hopped it sent massive shocks through the drive line every time the car landed.
It's amazing that a dragstrip is still not smooth enough for a perfect top speed run! They feel like glass in a car!
Would love to see some data logging on the normal tarmac vs the sticky tarmac on the drag strip!!! Thinking the amps and voltage drop will be massively higher on the drag strip⚠️⚡️🪫🔥
Kev please make some testing on it🙏🏻
Would really love to se how much more the setups sweat on that strip!!
Thanks for the video😊
I would try aluminium wheels with perforations on the road surface, then set into a mold allowing the foam to pass through the perforations from the road surface into the inside of the rim.
Would be difficult to setup, but once done the foam no longer needs to be bonded to the wheel.
I'd love to see Kev build a drag car - maybe not jump into top fuel/funny cars but maybe Super Comp or Street Eliminator
omg i was thinking the same. maybe pro alcohol. we know he wants a loud car haha.
Race tracks are finally getting smart and bringing in influencers to help promote the track.
Kevin. Maybe a dragchute would be useful to help stop the cars especially when you have no breaks?
Just need to remember to have some bungy cord to absorb the shock of it opening. 🤔👍
I like track racing so much more than a thing just going in a straight line and after 4 seconds the run is over. But to each their own :)
WOW! what an awesome experience!!!! so many different fun things happening!!! M2C 6 LUG HUBS MADE IT THRU!!!! btw, now you know what your infraction feels like!!!! Keep it up you'll hit the goal!!!!
When you overpower a high traction surface to get wheel hop. The tires don't completely break free but they break traction and gain traction in rapid succession causing a hopping effect.
16:28 Never thought I'd hear an RC car sound like a spooky ghost lol
I absolutely think the reason you are getting the bounce is because of the prepped track surface.
Same thing happens to real cars when they have too much grip, it’s called wheel hop. Wreaks havoc on the driveline parts.
Those little cars with all that power need to be able to have a little bit of wheel spin, I would think. Especially when accelerating early in the run.
No such thing as too much traction in drag racing.
Wheel hop is caused by the driven wheels pushing forward and losing traction. On an IRS setup you see an increases in toe angle which causes the wheels to slip. Once the traction is off they snap back to their normal position, bite back in, slam forward again, rinse, repeat. It happens on live (solid) rear axles when the whole diff assembly rolls forward, compressing the lower trailing arm bushings to a point where they cannot move anymore. The sudden bump as the diff hits limits causes it to break traction, which allows the diff to fall back, wheels to bite back in, push forward again, also rinse, also repeat.
The answer is always a stiffer bushing in your lower control arms (IRS) or sturdier trailing arms for live axle racers. Considering the twist visible in the lower control arms at the end of the video this is almost certainly whats happening. I would be putting a solid control arm at the front instead of a damper as Kev speculated. Hopefully he'll have a look at some drag car info for advice.
100% that's why. The prepped surface helps with traction but it also prevents the wheels from rotating by increasing rolling resistance and since it isn't consistent, you get wheel hop.
Maybe alloy lower arms?
@@KevinTalbotTV no, just stay off the prepped surface, it's also weakening your foam.
Went to japshow finale last Sunday at Santa pod with square society. You definitely went faster than my friends in their nissan cubes. Best was 18.8s at 72mph 😂😂😂 life's too short to be normal. Great video.x
Greatest 4 sec adrenaline rush you'll ever experience.
WRAP THE RIMS IN A LAYER OF KEVLAR THREAD then put the rubber. Wheel expansion puts the thread in tension which it's very strong.
I raced Santa pod years back it certainly seems bumpier with small scale …great vid
I think you need a mini dyno for testing and simulat the max rpm and the max speed from the tires... Thanks for the great Video 🖖
The percussion from a Top Fuel Car off the line definitely stands you in place!
Seen a couple good ideas in the comments like urethane wheels similar to skateboard tires. Like the one comment about machined aluminum wheels with some type of tread. Think until you guys invent your own wheels and tires they (tires) are what is going to stop y'all from 250mph. Great, Great video Kevin. We know you'll figure it out. Keep on keepin' on.
You gotta glue your tyres and start off the glued part of the track. There is so much rubber on the glued part of the track that it makes it bumpy making the car unstable even before it hits high speed
Finally a new video for this car 🙏🏻
Great video Kev, drag cars and a quad motor RC doing nearly 200mph :) awesome content:) keep up the good work.
Absolutely fantastic day out and Thank you 🙏 again to Santa Pod & Yourself Kev 🦾
yes mate!! epic day thanks for joining us
Great effort Kevin - an amazing amount of work! I haven't read the rest of the comments, so somone may have suggested this already, but how about titanium wheels? Lighter than steel and stronger than most other materials. Realise this could be expensive, but the time you've invested in this could make it worth a try?
Do some testing with using the glue that's used on a prepped surface. You'll find the foams, rc tires and drivetrain are negatively impacted. The glue will literally pull the tiers apart and cause lots of problems/ slower times.
I did a 10.34s standing 1/4 at Santa pod on my almost stock 1999 Kawasaki zx9r back in the early 2000's. I know it's slow compared to the monsters they usually run there but it's still competitive in modern day bikes. I was quite a bit lighter in those days mind you 😂😂
Keep going mate I believe you will get there I have faith in you
If it's a gluing issue, I'd say get some aluminum wheels, knurle the surface, bond CF as a band around it (probably help with it staying together anyway), then glue your tire to that. Those plastic jobs I don't think will ever work, unless you had some custom glass reinforced or something, but that would be a nightmare to try to make.
A follow drone cam would have been nice, but I still enjoyed the video. 👍👍
Try that marine rubber sealer. Its white. Super sticky. Let cure. It should help with tire tread staying on
Before you hang this up, I’d love to see all the shocks and tires from the lawn board on this body to see how fast it will go on the grass.
Whatttt. I can’t believe you don’t have metal diff cases and metal internals or rally diff lockers
And this is why I love drag racing
This rc car makes more power than my daily real car😂
Speed runs have to be one of the most expensive forms of RC. Excluding planes and Helis
18th on trending...go on Kev!!!
Try a hockey puck honed out on a lathe with a carbon fiber exoskeleton inside. Solid rubber is key. No glue
You guys should race those against the drag racers. That would be epic if you guys beet the dragster with your rc cars.
In order to get ANY glue to stick, you need to roughen the surface. How about grooves? Make the aluminum tire a paddle wheel. (But not THAT massive of grooves! ;) )
Is anyone else amazed that these little rc cars are making enough power to still spin on a prepped surface?
It’s crazy how fast those drag cars are
I might have mentioned it before but make wheels out of Hockey pucks you will have to use a lathe
The support webbing in those white wheels that broke are catching the air like prop blades and creating alot of VIOLENCE!
The hockey pucks will be one complete piece wheel and they are hard rubber yes there will be more weight but i don't think you have a problem with that
You should drive it with a VR goggle.. would be epic
I wonder if getting some plastic wheels and some smooth rubber tires to cut up, you could glue the rubber on to get maximum traction on the drag strip to help with top speed.
Kev, you need to upgrade any part that breaks bu a factor of ten...
Running 100hp in an rc car is bonkers, you neex to strengthen all the weak links by a shed load...
100hp is what a full sized car has so the small parts of the rc just cant cope with it XxxX
You know it was going fast with a debris trail like that. @22:00
Aluminium bonding is commonplace in F1, just requires bond prep (degrease and abrading the surface) as well as a decent 2 part adhesive such as 3m9323 or even araldite, unless the temps are high... Carbon rims would be a science project IMO. Good luck!
If you make the rims in aluminum and like radiator fans. Then u might get more stabile and it would hold up mutch better. I believe it would help a lot. Keep up the good work :)
Kev you need to talk to east composites about your speed record attempt and see what they can do to help with your wheels, they are market leaders in inovation in carbon
@Easy composites
Love your videos man, can’t wait for you to break the record!!
great video.. good to see others crash beautiful rc cars. heheh GAME OVER AND OVER
As it seems impossible for plastic wheels to survive how about taking a leaf out of Richard Nobles book and fitting some titanium wheels ,I know grip may be an issue but if they had serrations on the surface like a circular saw blade or splines ,expensive yes but maybe try with aluminium first ,just an idea 👍
You could use two part epoxy to try and bind the tires to an aluminum wheel. I like the carbon fiber wheel idea I wonder if instead of foam there is another bonding agent that you can apply directly to the wheel and lathe down to a smooth surface. Like a rubber compound like plasti-dip.
What about using something like poly skateboard wheels ? Maybe molding them over aluminum rims?
225 MPH in 4 seconds is quite impressive. HOWEVER, here in the USA they do over 330 MPH in a little over 3.6 seconds. Let that sink in.
How can it be 100mph more but almost the same time?
kev 10 years later: world's fastest rc car
Use aluminum wheels and do increase the friction of the wheels by using sand paper because of this the glue will stick supper strongly with the aluminum and also with the wheels
Actually kinda funny that you guys run 1/4 mile there.
And swamp thing is a ford super duty
The weight is deforming the tyres.possible solution is to add support in the middle..2 more wheels or just a ball bearing contact point
You should use parachutes like the drag racers.
get some hockey pucks and machine them into wheels!
bonded and belted neoprene my friend.
nice vid kev, fab job.
Traction compound on a drag strip is gunna kill those tyres in seconds
you might be able to glue rubber tires on aluminum wheels but you are right it would all have to be custom made.
You should try running those plastic wheels bold without foam on that surface if it’s that sticky
also what about a solid plastic wheel? something soft enough to grip but stiff enough to hold your hex cap system
you should put a cmera on the car to see where its going
Max dont seem to have a speed car unless I missed it. So does that mean you and his mum are a thing and you and him are spending quality time together or do you just enjoy his crazy company? Asking for the audience.
Awesome 👍
I love max
Part of what hurts the car it’s heavy and no rear Suspension at all.
You’d need a absolutely perfect surface at those speeds. Any wave in the road loads the tires and they end up taking extra load. I’m not saying have a large range but something would be useful. Any bump is transferred into the tire first.
Bouncing and hopping?
Porpoising maybe?
The foam just isn't tough enough for the torque being applied. You have to use some kind of synthetic rubber with steel or aluminum wire embedded.
just like the cars that speed run at the salt flats they use aluminum wheels without tires, if you run the car at santa pods prepped surface traction wouldn't be an issue running aluminum wheels without tires.
This may sound crazy but hear me out: ”SKATEBOARD WHEELS”!? Meant to endure loads of grinding and can withstand up to 85-86 000 rpms according to tests. Not much grip but maybe enough with some modifying?
Why dont you use tiny bits of steel cable to help hold the tires together although idk how well rubber tires that small will do
Next time put a catch net of some sort at the end of the track
It'd be cool to put an FPV camera on that car and use goggles for full immersion.. should be mental..
Is there such thing as a parachute for rcs? Just an idea, might help prevent as much damages and help slow down better
Fun fact - top fuel dragster engines are only designed to last about 900 revolutions
I'm wondering if it might help to move some of the rear components weight to the rear tires to help with traction and wheel hop.
You should try scooter wheels or skate bord wheels
Kevin have you ever thought of using skateboard wheels, or the same material you might be able to design something with that in mind just a thought
Yes aluminum wheels kev
Jesus he spun on the strip
Wait till you see the drag cars here in the US, they hit speeds of almost 350mph
What about 1.9 Beadlocks with a rigid foam insert (cut down) and a low profile tire
