@@KevinTalbotTV nice all the time you do this

That flip was like a Mercedes clr race car doing the flip
Same cause too
I know right this gave me ptsd (joking i dont have ptsd)

The aerodynamics never change. As soon as the rc car left the ground I knew it did the same thing as the merc. The join was not flat and for the same reason as hitting a rock you really should walk the runway and spot these kind of things before doing a top speed record run.
Kevin: "Let's see how fast it goes!"
Car: "To the MOOOON."
Kevin: *"OH NO!"*
this literally made me lol
Also Kevin: .....anyway
Also The Revs went to the moon
Also Kevin: anyways why was that happening
I see that runway is working as intended as it was able to make your car, “take flight”
Failure is not failure, if you can learn from it and adapt. She'll be back!
My wallet be like🤣🤣
Ricer: put a bigger wing
Normal people : 😑
She’ll be better than ever when it happens
True
Maybe if he actually put some time and effort into aerodynamics instead of "MORE POWER" then maybe he has a chance to beat the record. But the way he went about doing this project was more just for fun and youtube clicks than anything else.
11:33
Kev: Lets go for that world record of 103 mph
Yes i noticed that as well haha
But that's the goal for the WLtoys, isn't it?
103, that's like brushed motors speed
I was trolling the comments to see if anyone else noticed that. Lol. Let's get it mate. 💪
Smashed it !
Rear toe-in helps with straight line stability, at the cost of a tiny bit of extra rolling resistance, so I'd say a bit of toe in would be good.
8:27 i think you should ask with some engineer or sth for a front wing. That would solve this problem, its not going to increase the downforce with weight, but with air. It maybe sounds ridiculous but your project looks really serious, and it deserves more development. I love it!
jup. he has too much downforce on the back. this is why his car flips every time.
and dude should seriously do some cfd analysis.
get yourself some mechanical engineering student/graduate and lets go.
Hey Kevin. I think your problem may be rooted in the fact that you have so much power and rear end downforce for the amount of front end downforce, making the car want to pitch up. To combat this, there are a few things that I thought of that could work. Firstly, you can add some preload to the rear suspension and add to the front, which will make downforce along the entire underside of the car. Secondly, you could put vertical sides on the top of your splitter, kind of like aeroplane wings to improve the efficiency of the splitter. My third idea would be to drill a few small holes in the top of the front wheel arches (I’m not 100% sure if it would work, but it’s probably worth a shot),to decrease the high pressure region inside the wheel arch to remove any lift it could be creating. You can also try running a lower top speed setup on the rear (not with aero but instead maybe with gearing in the “differential”) so that if the front starts to lift, it will be brought down by the slower speed of the rear wheels.
I hope these ideas help
Like so Kevin sees.
Mostly, it was the gap that did it, passing over it at that speed was ill advised from the start. Uneven surface is no joke at high speeds.
The second idea is great (vertical sides on splitter). I'm not sure how the other two would affect it. You've clearly put some thought into the comment. Worth considering, I would think. 🤔
Putting holes in the wheel wells is not good- it is a low pressure zone due to the high wheel rpm. (Fast moving air =low pressure)
@@ctsd623 actually holes in the wheel wells is a good idea, in fact, a mandatory feature in full size le mans 24h lmp1 cars.
@@wade7959 maybe a bigger splitter altogether. This car really needs some serious downforce at the front. And, since power is not an issue, it won't hurt the top speed.
Drag increases exponentially with speed, so 130mph is not even close to 203mph. This may be an opportunity for a complete redesign.
There is always more room for more power!!! Haha
You're right that it's not a linear relationship, but tt's not exponential either. Drag increases with the square of speed, power increases with the cube. 203 mph is definitely a long way from 130 tho.
@@Jefferson-ly5qe so you say it's not exponential, but then say that drag and the power needed to overcome it increases exponentially. Which is it?

TOMLEY Kevin, Phill’s runway is perfect. Collaboration time.
Hey Kevin. I don't know if you will see this comment but I believe I have a way to stop your car from flying. I suggest to distribute more weight upon the car. Take the Mercedes CLK-GTR that was racing in Le Mans 1999. When the car took off it would create a huge up force that caused the car to lift off the ground and fly exactly like your car. It had so much power but not enough downforce and weight to keep it from taking off like an airplane. Hear me out, the only time you would need to go lighter than heck is for an airplane as it needs to fly. Cars aren't supposed to fly, so they need to stay grounded. Just like the Koenigsegg 1:1, where it has a balanced power to weight ratio to keep the car grounded to put that power to the floor. I suggest to place metal plates or use liquid gravity like you did to that one boat a long time ago. Use the same principle with the metal plates like you did with your burn out car with the metal plates or however you see fit. You can also lower the car a bit more, and find a flatter smoother surface for your speed runs. Along with using canards on the body and maybe even an open diffuser for the front of the vehicle. It's like a spoiler for the car but it fits upside down and under the front bumper of the vehicle. I hope this helps in achieving your goal. Can't wait to see the next update to this cars performance. See ya soon!
I'm addicted to this project... I feel like we're all in it with you Kevin.
I have a crazy idea, why not fit a spoiler in the front? Since the car is too low for a propper lip/splittrt. I saw a GTR that was build for hillclimb and had a spoiler fitted in the front. Then you can firm up the suspension in the front and using the downforce to keep it stable on the uneven road
Had same idea. He wont need hardly anything
Genious
Would create too much drag. It doesn't really matter for hillclimb cars as those are built for maximum downforce for cornering. For a speed car you want as little drag as necessary while providing just barely enough downforce to keep it stable.
If you want to take inspiration from full scale cars look at land speed cars, the concepts used there would apply here more than something from a hillclimb or time attack car
canards?
@@KacKLaPPeN23 what about flexy wing? like the ones the use in f1. too much downforce will flex the wing down and reduce downforce
Kevin, since you've customised so much of this car anyway, why not go the full hog and fit a custom body? The problem at higher speeds is that the pressure variations across the body are increasing and any slight change in yaw/pitch will amplify those effects and send the car into a spin. The new body should be a simple oblong with a rounded nose and a boat-tail at the rear to minimise base drag (no need for a diffuser then). You could have a slight slant on the roof to provide some down-force, which will increase significantly as you gain speed so doesn't need to be an extreme angle. Add a vertical fin to help with stability and remain in a straight line. Really stiffen the suspension to prevent bouncing, and obviously run on as smooth a surface as possible. You could still keep your original body, but it would be interesting to test them back-to-back and see what impact the aerodynamics is having. Good luck!
this project i want it to look like a car, next project ill so a bullet shaped thing
@@KevinTalbotTV only reply 😂
Love this project. On the outside, it's complete folly. "More power" didn't end so well for the tool man, ever. But what I love is learning about the process, the whole way through. You're working with stupid big rc gear, creme de la creme of the tech available. You consider all angles, you test, you destroy, you rebuild, you test. It's quite educational. I find a lot of these pieces of info quite useful in my much less power rc's. It works. Well! So thanks for what you do man, crash, or 203 mph., this is a hell of a ride!
I'm glad that you are a learner, you break stuff and spend money on rc cars, but you don't get mad or frustrated, you try again differently, thanks for a great channel!
It's so great to me to see kev completely talk about how it's a lesson to be learned yet having such a happy and peaceful state of mind, that is the kind of motivation and non self doubt humanity needs ladies and gents.
That’s because he’s got the financial back up to just replace expensive parts.
You aren't wrong, I'm only talking about how happy and how mutch of a good mood he's in all of the time, it makes me happy to see him like that 😊
The only mistake you taking a car on the runway and it wants to fly 🤷🏻♂️🤷🏻♂️😂😂✌🏻
Just kidding 😋
Keep up the good work bro 😎
Lol
Sorry wrong emoji
🤣😄
Was thinking the same.
Runway = take off 😃
stumbled on your videos by chance, stayed cos you make good content that revives childhood memories. nice bro
Loving this series! Maybe also try adding some louvered wheel arches to relieve pressure in the front wheel wells and add some more front end downforce. I’m no expert so I may be totally wrong, just a thought lol
I think it would be cool for you to make a custom body shell. That way it can be made to really be efficient and simple. Maybe out of depron or some sort of foam and then vacuum formed plastic over it to form the body? Could be cool. And don’t listen to the “experts” in the comments. I know that if you spend enough time on this you’ll get there eventually. Good luck!
Not without considering the aero and suspension he won't. He might get there, but raw power alone won't do that.
I think he wants it to still look like a car
This is a battle between science & MORE POWA!
more power has to win!
Yeah XD
@@KevinTalbotTV if it’s possible, renting some wind tunnel time at a local university to dial in the aero at 200+ mph could be beneficial.
Between science and ignorance, more like.
Thats also Jeremy Clarkson's motto. "More powaaaaaaa"
Good luck for the rebuild! And even more luck for your next runs ;o)
Good attempt - great things learned. It's hard to react at 130+ haha
That FlySky is the BEES KNEES! Great remote - wish I could get one soon.
To stop the front lifting at high speed you need to drive it in reverse. Just saying..... 😉👌
Hi
@@renukapuar3107 Hi
actually a little extra droop on the rear wing and stiffer front suspension and he will keep the front end down better ... just like lemans and formula 1 cars ... more downforce to keep on the road and more power to the drive wheels to go faster than the other guy ...
The wheel arch missing let so much air under the body I was nervous from that point on. Figuring a way to seal the body and chassis air tight should help a ton, right?
mate, you are out the gate! love it
Kev you often learn more from your defeats than you do from your wins! 💪👍 Wes, Liverpool UK
The rotary tool at 2:22 sounds like kev saying neeeeeeeeeow
Hihihihih
Lol
2:20
Lol
Hey Kevin, big fan of your videos. In my experience, you’ll want to keep that toe-in in the rear to eliminate fishtailing. That way the rear tires will be pushing in towards the middle against each other providing more stability. Also, if you Velcro the sides of the body to the chassis you’ll reduce parachuting and save the wires next time. 😃
MORE POWAH I love it kev love the vids keep up the good work
“Complete Novice” *Also builds rc vehicles faster than I take a shit
You must shit for 5 hours at a time then 💀
@@DoggoDaOne I do..
also says it while standing in front of his workshop specifically built for RC cars.
You may have failed once, but you will come back stronger. You can do it Kev, we believe in you
R/im14andthisisdeep
Looking forward to the next instalment of this series. There are more lessons to learn as you creep closer to your target speed. 200mph is really fast. The bump was definitely the biggest problem in this run.
My fav so far of all your vids.
Do a wind aero test using a builders scope and while increasing the air flow you will be able to monitor at what speed it the RC will start lifting up and calculate by adding weight to the front end. Do a road test on asphalt, concrete has expansion joints, you will flip every time on concrete.
As Jeremy Clarkson would say "More Power", In all seriousness, I hope you get the top speed record someday.
No, Jeremy would say
“Speed and power!”
And
“SPEEEEED!”
before him it was tim the toolman tailor who always said More power ... also known in real life as tim allen ... jeremy clarksin stole the line from him ... he did NOT make it up ... he just ripped it off ..
He says "Speed is the answer to Everything"
So definitely didn’t get as fast as I thought it would today but there’s so much more in it!!! Is there a drop screw adjustment or fuel tube for the front shocks to keep the front from lifting? That could’ve been so much worse!! That damage is pretty minimal considering you lost it at 138mph!!! Great video as always Kev 👊👊👍👍
Hey Kev! Just making an observation here that might possibly prevent some of that air from getting up under the body, or at the very least prevent it from folding into a literal parachute. You might be able to drill 3 to 4 or more small holes on the left, right, and front side of the body as well as the chassis and run some fishing wire or something similar through it. This way your body won't fold back, and hopefully next time you get airborne it won't be so aggressive. You may also be able to fill some air gaps between the chassis and body shell with something like painters tape which i could only imagine would help that much more with this issue; and it may actually improve your aerodynamics as well! Second observation; Next time you go to this landing strip i would suggest starting off slowly at the smooth end, and then once you're on the black top you can ramp up your throttle as needed. This way, in theory, the RC doesn't get airborne, as i think that small ledge is what caused it to invert like an umbrella.
Also; Here's another idea that might be interesting for you to look into. google the Brabham BT46. The BT46B generated an immense amount of downforce by means of a fan. This downforce, Given you had enough of it, would in theory prevent the RC from ever going airborne as well as solve any traction issues.
Adapt, improvise, and overcome as they say! Keep at it, you will get it.
The expensive and money backed endeavors always get there but the "Everyman" gets there with passion and persistence. Keep it up!
And, the attitude is what it is all about. Your attitude is exactly what needs to be shown to those who watch. You don't whine about it - you keep moving forward!
A recommendation is to make the rear wing a little smaller, cause on real cars more downforce= more drag= lower speed and ecceleration
At that speed you need some amount of downforce to keep the cars wheels planted on the ground. Having no downforce means that the car will lift and then no wheels are planted on the ground and you cant again speed
@@nikhilstephen6177 yes I know but at the speed the car is going, the shape of the body will be enough to keep it on the ground.
2 things a top speed car needs to do, go straight and not fly. The vertical fins do a wonderful job of keeping the car pointed where it needs to. As long as your body does not create lift but a little downforce that is perfect for high speed. A big wing will create to much downforce as the speed goes up and all that drag will slow you down. The rear suspension was bottomed out at 100mph and he wants to go 200? Yeah to much rear wing.
Surprised when he crashed it he didn’t say “now it’s time to finish it off” 🤣
Don’t think he wanted to blow 4 gs
Seems like it would be a great hobby, I love the pit stop garage too, I could see getting lost modifying it. You're just gonna make some adjustments, turn around and it's four in the morning. Great video
Love your videos Kevin! Not seen them all yet but working my way through them.
I have a suggestion when you are performing these speed runs, some sort of barrier/shield protection for the spectators. I'm in no way a killjoy but imagine losing the steering at 130mph and that car hitting someone...
I can see why the guy who holds the world record put so much time into R&D lol.
Yep, at those speeds, it’s all about airflow. Kevin will learn the expensive way.
But i'd be awesome if some one without in depth knowledge hits a new record.
Even a few moments of R&D would help.
Yes but you see the expensive way makes him money via entertaining CZcams videos XD
Title should be "Mercedes CLR recreation". Like Le Mans in 1999, Mark Webber just flipped into the air at mulsanne's corner
Kevin I would like to see you get the car going again. I don't know if you can compete with a totally custom made car like the world record was set with. But it would be interesting to see just how fast you can get that car of yours to go. The thing I like about your car is that anyone can purchase most of the parts online and for the most part it's a production chassis. My two cents. 1. Find a smooth surface to run on. 2. Treat the area with some sort of traction compound. Grape Soda works. Or my favorite was VHT Track Bite that professional drag racers use. I mixed it 50/50 with denatered alcohol.
Enjoy your videos.
Roger.
Kev long time subscriber love your content man keep up hard work man!!!
The fact that's faster than my 1996 honda civic is funny
So is that the fastest double backflip with an rc car? 😂😂👌👌
Yes
Probably
Hey kev,
I know you want to build this with the idea of "more power more speed" but, consider taking my friendly advice.
Try putting a front wing and a more effective back wing. Make the suspension stiffer ESPECIALLY THE BACK ONES and make the front ones a bit softer, so they compress exponentially with speed cause of the more downforce, so it will solve the problem of the car getting airborne.
The problem with wings is that they add drag and therefore lower speeds can be reached
Lol love Talbot.. think I've watched more of these vids than any other channel
That’s amazing you can develop 36 hp with that setup.
Use a drag strip instead. Straight and grippy.
Hey kev would it make sense to open the shell behind the wheels to let air out as soon as she starts to fly? Or something like the nescars got like an airbrake
Awesome video man, keep up the good work you'll get it.
When it flipped, i had a heart attack.
I think you need to make it longer and put every thing in the front
I love this... it's little videos that I find like this that makes me happy that I'm still on this planet.
Looks like it was crazy windy too 🤣 I can't imagine wind being the friend of a relatively weightless rocket lol! Coming along fancifully though I say!
It bean 10 months sense you didn’t rebuild the fastest rc car I want to watch next video :(
Add gyroscopic wings (auto correcting wings) in Front and it will auto correct it and flipping (so just a smaller version of the Batman wings in back to the front)
Kevin: More Powaaaaaa
Nolan from Donut Media: More Powa Baby
Great Build Kev and damn good effort! The record holder has a lot of weight up front of that long chassis... Your weight bias is at the rear. Get some weights in the front Lad and send it!
Toe in is actually good for straight line speed
Huh, as far as i know it doesn't really matter since you are only going straight lol
It does. These things are tiny compared to fullsize cars, so they need the stability even in a straight line.
Make the suspension really hard or just replace the shocks with a metal rod
Generally, you need suspension to smooth out the bumps. Removing it just makes the car (a lot) more bouncy. You can get away with no suspension if the surface is smooth, not sure it is (smooth enough) on any normal airstrip though.
Running no suspension will simply not work, as said already. One small rock and boom, every ounce of traction is gone, that car will flip or spin regardless of what happens then.
You are definitely not the noob you claim to be... and I like it. Well done, nice attempts!
I love the fact that even you failed you still don't give up :)
Just here for all the expert comments on how you should do speed runs.
Lol!
Love the content mate, keep it up 👍🏻
well it is true that to beat a speed run record you have to go faster than the last one ... so everyone has that part down right ... after that they all have some good ideas ... and the naysayers wont ever accomplish anything because they arent even trying ... from what he has done so far he has a good chance at getting the next record run ... he does need to get past the air lift on the front end ... learn something about aerodynamics will help with that .... and then find a nice smooth place to run .... he's a heck of a lot closer at getting 203+ Mph run in than most commenters on here if not all of them
everyone when the 203mph took another spin: YES YES YES
everyone when it crashed and wasted almost $5k: NO NO NO
Sugestion. Get rid of the wing at the back and place something like this more in the middle of the car. Maybe somewhat adjustable to balance downforce/drag.
Not a fail! You are getting really close now brother keep going!
Why don't you just put a wheelie bar on it?
Not gonna stop it from lifting at 130mph+. The air gets under the nose and nothing is stopping it from the tumble wumble
0:59 when will he realize that you don’t only need “more power” to go at a high rate of speed. Nic cases car is almost 3 feet long and is very aerodynamic.. I think he needs a better chassis
a flat runway with out bumps will help a lot too. there's a few guys in my arrma group that have hit 170+ mph with the factory limitless body/chassis and some grp tires. but i agree better aero is always a good thing. he could also cut some slot in the rear to help trapped air not make the body parachute too possibly.
Years of testing and development vs MORE POWER and epic flip dude
Down force down force down force. Fit that front end with fins that will direct the air evenly over the body and you can angle the front end aero down a bit. Add a small piston system if you wanted to the force while accelerating will push the front lip down to close the gap against the ground. And air that gets under it will send it. Amazing though this is so promising
a lot of armchair experts here!
😂
Having a blowover merely means you ain't going fast enough or ain't got enough downforce
bump in the road will make anything lift off at speed
Very thought provoking. Makes me wanna try something like this.
Hey Kev, if you have range issues go see if you can find a transmitter with JR module bay and get TBS Crossfire for it. That's what we use for LongRange flights on our planes. 50km+ out and back
Fun fact: you can’t get pregnant from a bird
Me and my wife Candice found out the hard way…
Candice? Who's Candice?
quick tip that i’ve learnt, it’s a good idea to keep that angle (if not just a little less angle than stock) on those rear wheels because the friction of the ground forces the wheels in an outward direction making the car unstable
The radio link radio can easily do 600 meters but you have to use 4s batteries. I run mine on 3s (3 x 16650 batteries) and I can get 500 meters, I havent tried any further. The radio really has a lot of features. My favorite is the fact that it has a screw hole to mount a camera under that rubber cap on top.
so let me ask. this man crashes a 4000 vrum vrum car and laugh and says WAH HAPPEEEEEENNNNNNNN. kev is just built different
Hi Kevin. This is very cool project. I think this car needs more down force on the front end. It will prevent it from flying away. I would suggest to install spoilers on front lower corners. Maybe it will be useful to add little weight on the front. Sticky balance weights for real car wheels will work perfectly. They are small, heavy and easy to work with. Will fit under the body shell.
6:18 Yannick Dalmas watching this:
"Welcome to the club!"
sad to see it but not surprised XD. keep up the content Kevin, great to see the journey of trying something new.
When I saw the gaps on the runway, man bad idea. Anyways, really enjoyed the build and hope to see you smashed the record. You got a sub mate. cheers.
New to the channel, great videos you are made to be on camera lovely stuff
Welcome aboard!
First thing I would suggest is make your chassis all aluminum. I’m guessing that could give a little bit more weight to have your rc have more downforce in a straight line. Stiff up the rear shocks as possible too. It’s my guess. Don’t give up too. You can improve much better!
Kev: I don’t want to change to much on the car.
Also kev: 2:27
You can't move forward and be failing at the same time it's not possible. Nice video Kev.
Kevin, you should take the parts off it and mount it on a children's longboard like your longboard RC truck and go for a speed run. With the long wheelbase, it will not flip over. If anyone can do it you can. It's 4 wheel drive, right? Mount the front and rear end on a children's longboard. It would be epic, lol.
I just started working at my local hobby shop! Love the channel man! I could use a AWD drift car if u got one!
That musty flick was smooth doe
That gave me a good flashback at the 1999 Le Mans with the flying CLK GTRs.
