Chasing RC Cars Speed World Records

[@tyran370]

Always nice to see some truly top notch professional puncturing on display.

[@ellc.6143]

So for me not boring. The more I know the more chance I have to succeed in whatever I'm doing with my rc. So thank you for being detail oriented and bringing it to us. Thank you!

[@timothy_pulleyn]

This was all really really interesting! Thank you for the insight - fascinating to see the detail behind all that can go wrong with a speed run!

[@MrBumbles2]

lol a fire climax is always a plus. but information is never boring

[@smoothrc28]

Great Video!! I like all the info and appreciate it. Even though I don’t do speed runs. But used to race banked oval. With pan cars. So i know when you say there is so much involved to go that fast. It isn’t just a big motor and a big battery. It’s so much more. You definitely know how to set the car up. I would think once you trim it to go straight. You don’t touch the wheel anymore until you have to turn around. I could be wrong. But going that fast you wouldn’t want to touch it. Or you will tumble for a mile. Lol. Great Video!!👍👍

[@mikefordham6546]

Not boring, very interesting in fact, thank you.

[@NahBahDee]

Mr. Raz your level of attention to detail and perfection is impeccable and well deserved. There is nothing boring about what you do.

[@NahBahDee]

@razshifrin_7 are you the real Mr. Raz or some bot trolling all of us and impersonating Mr. Raz? What account is this?

[@brucebruce3964]

Raz I’m glad to see you in the speed game. I’ve been wondering all these years while you haven’t been absolutely crushing these people you’re simple weekend Monday bills are out of this world. Can’t wait to see what you do next.

[@lutach]

Reason the R/C Hobby doesn't get the respect it deserves is the fact people still thinks these hobby grade machines are toys. Tell me, how does your hobby grade machine compares to a R/C toy found in let say your Walmart? Remember Toys "R" Us or Radio Shack, yes those were toys and I think I even saw them mention in some of the toy models being hobby grade, but it was hardly that. I really hope to see one day people change the way they think about these sophisticated machines that can sometimes equal the technology of highly advanced full scale vehicles. Finally if you consider these machines toys, how are your toy grade parts?

[@ericbarber1584]

I wish I knew half of what Raz knows about RC’s and speed runs. Always fascinating videos. Keep it up mate!

[@based_will]

So funny seeing someone be bummed about 214 😂 like I get it you’re chasing the record but that speed is beyond my wildest dreams! Keep at it Raz u got this!

[@jhawk1985]

Im still having trouble breaking 100 mph with my 4Tec 3.0

[@bigboytoyzrc9258]

​@@jhawk1985go mod1 34/30 on 3s and thank me later🏎💨

[@riskaddictionrc]

Right. I wish I had a 200mph curse!!!

[@PCaimb0t7]

yeah but i would have the same reaction if one time it went 218 then to 214 but it’s super fast still it will take me 50 years to get there

[@jasonjohnson6085]

My dual Hobbywing 4268 2600kv limitless one of the esc wires came loose from the splitter and released some smoke. I thought for sure I fried something. Fixed the wire, ran it after cool down and it still put down 142mph on 6s. Motors smell terrible but still worked. I was surprised. Glad to see you back making content. Appreciate everything you do for the hobby

[@lo666zz]

Blows my mind the speeds these creations can achieve. 2 questions 1. How far is the actual length of the runway past you once the car passes you? 2. How do you even see it once it passes you going away? 😂😂😂. Massive enjoyment of your video's and explanations. Big ups from New Zealand 👍

[@RazShifrin]

The run is 1km long start to finish

[@raindeergames6104]

Raz what I do is I drill a little dimple on the motor shaft and the grub screw bites into it. Never ever comes loose

[@hobbymanrc79]

Another epic running video! You guys make going 200+ mph look easy🫡

[@spiffywho1582]

I'm excited to see what you do with the armma fireteam. Thats my favorite 6s out.

[@VS666]

Love the technical bits, I was always scared of electricity but when I got into RC I knew it was time to learn a thing or two

[@M4A2Master]

Hey if you haven’t already you should time the position of the polls timing on the motors by moving the pinion one tooth when meshing it with the spur gear so all the motors don’t pulse at the same time. Like imagine a 4 cylinder engine and all the cylinders firing at the same time. 15 years ago we were doing this with dual motor setups and it helped a lot with smoother acceleration and cogging. Also if you do lose a motor it’s not as hard on the remanding motor’s. And for anyone wondering I do have a bachelors in mechanical engineering and am ASE master certified.

[@Skyhigh_RC]

Kevin wasn’t first !🤷🏻‍♂️😂

[@johnlincoln4616]

He’s getting it now😆

[@valiant7357]

What happen!... 😂

[@crazyrusty7688]

NNNNEEERROOOOOMMMMM!!

[@Captinfun101]

Boom!!!

[@babyboo7babyboo788]

Hihihi

[@rcfamily4life74]

Awesome video brother!!!! Now I know more about my TP motors!!! Happy RC’ing Y’all!!!!

[@kaiarneberg9203]

Not boring! Learned alot!

[@micron3268]

Sure did!🧐👍

[@scottkernan9007]

I'm so glad there's guys like you and all the others that are doing this

[@allenmichaud1605]

Great job buddy keep it up. Proud of you. Seems real tough with a chance of costly fire

[@MarkHahn]

That is such a cool build. Nice and clean and SMOKIN fast! If anyone will break the record it will be, Raz.

[@TurtleRc]

Easter Egg. Love the look of your new Perfect pass diff housing. Matching the A arms looks killer!

[@Jackpot1711]

bro. your nation is fighting Humus and here you are playing rc... keep it up ..😝

[@AntiVaganza]

I still don't get why aero is seemingly so overlooked. I mean, it's understandable that people are throwing power and battery tech at the problem, but right now that seems to have plateued a little. But the bodies still have features that are unneeded. Drag has a direct corelation to fronttal area, right? So, why have a canopy in an RC car for instance? I guess all this have been tried, and perhaps forgotten, but if you are on a plateau trying to eeke out the last few miles woudln't it be worth looking into in depth?

[@Captinfun101]

That was one huge speed run secret with the heating box . WOW . Awesome. Side note: no boring vids no matter how geeky Raz.👍

[@chrisoconnor3119]

Just stumbled upon your channel and I LOVE what I see! TP Power, Castle too...wow What chassis are these? Curious about your differentials also.... I will scan your other videos

[@rtz549]

Is the overcharging and pre heating of the batteries really necessary?

[@Slikx666]

Well i don't know about anyone else but i thought the little talk about the motors was interesting. Thanks Raz. 😀👍

[@JustInvertedFpv]

You can shorten wires you just have to heat and apply enough solder to burn off the coating on the wires first then clean it up and solder. Been doing that with drone motors since 2015.

[@HYTTFilms]

This is amazing

[@RequiemRC]

Raz im begging you, please show us how you got a JST rigged to your trunk like that. Absolute game changer for me & my crawling crew when we're out camping on the trails!

[@eslmatt811]

Your best bet is a fused wire directly to the battery, that kind of amps through the car electrical system will cause problems with your car. Getting it to come out the rear will take more effort than from under hood unless your battery is in the rear.

[@jhawk1985]

you can sand the insulator off the copper wire. Ive had to do it before on a small TP power motor. It works. but I dont recommend it. The motor still works fine. It wasnt easy getting that insulator off though

[@thomasrussojr4603]

Raz you should be a teacher I learn alot just watching your vids Keep up the good work

[@h3llfir3rc]

Sounded like one of the pinions got loose on one motor and rpm unloaded freely. The rotor might have a crack now or somewhat now demagnetized as a result of RPM dumping. Best to replace the whole motor now.

[@skyhawk21]

Do you grease any gears or run dry on speed cars? What diff fluid or oil do you use?

[@scaleworksRC]

200+mph isn't climax-y enough, so he sets something on fire. (sigh)👏👏👏😁

[@petekobraoutdoors7324]

Hmmmm,Hobby grade,not toy grade, sounds better.... Crazy speeds,there,Razz 🤪

[@vwturbowolf]

Nice runs brother.

[@James-l6i5g]

Building me one soon just a few more parts. 🎉 your cars are beast I personally think a few more teeth on the p and it will be there like a 43t

[@XBB_very_good]

Coating on the copper wires are called varnished coating

[@Pyroteknikid]

...and that varnish is actually called polyamide-imide.

[@XBB_very_good]

@@Pyroteknikid No, not neccessary to be PI, some low quality brushed motors used polyuretane as copper wire coating and are easliy burnt😂

[@Pyroteknikid]

@@XBB_very_good True, I have seen a lot of cheap drone motors use urethane, and dont last long. Much easier to solder though...

[@reapersrcperformance8835]

Man these was an amazing video ,never fail to disappoint thanks man and keep doing what you do ow and p.s I just hit a 1.31 at 132ft at 107mph I'm so excited, I just wish we had a place to do speed runs and again good job bud 👍

[@FarmerFpv]

15:34 Greta Thumburger: How dare you! The fish are going to drown! 😂

[@Dogtraining-de3zm]

Good content sir! Level up and give us some large 1/5 scale speed runs. Be different from what everyone is doing. 150mph with a 40lb offroad 8skraton, losi 5b/Dbxle, traxx XRT or Kraken vesla would be just as hard and impressive as 223mph with a 1/7 scale on road car built for speedruns...Clearly limitless and hobao are proven platforms but thinking outside the box will help our rc community evolve.

[@zarakikenpachi820]

nice that you are back! exited to see what you are doing to my beloved fireteam 🤩🤩

[@xXB.FunkXx]

I hate when the batteries just smoke and don't light. And I like the technical stuff keep it coming

[@bengerber1521]

Raz I have a 8S Kraton. What do you think about conservative gearing and me using the 1721 2400kv in it? Is it too much truck for a high rpm motor?

[@lefthandscott]

Wow! The Master at work! I salute 🫡 👏🏼 🙌🏼 you Sir!

[@leonardsrcgarage1919]

Knowing your car down to the sound is crazy.. great video

[@Luke-en2tk]

James had a 218mph fire 🔥

[@neontetra1000]

Also.. why are you using differentials in a car that never goes around a corner ( unless I am wrong )? I would recommend lightweight spools front and rear .

[@pjpankratz8829]

Well if this Perfect Pass thing does not work out you can always be a cover singer LOL!

[@petejones6827]

we are using top of the line puncturing equipment AKA wire snips

[@johnclarke8180]

Great content, thanks for sharing!

[@darkcrawleruk]

Very interesting info relating to the motor.

[@myphotos]

Could you use one way bearings on the motor or drivetrain to prevent the motors becoming generators and killing each other?

[@parker1ray]

Crap, my best has been around 90 without Perfect Pass LOL!

[@roblow8126]

sounded like you hit vtec 😄

[@MitchellBolognaniRC]

Awesome video as always Raz 👌

[@masjuggalo]

I like that 224. Mph is kind of crazy for a RC car, but then you realize it's a 50 lb car with 160 horsepower

[@Scratch31337]

Nice disclaimer, keep it up, we believe in you!

[@allscalerc]

I always learn something new! Thank you for the amazing content!

[@peter.wilson]

The expression is normally "workhorse", not "working horse". 😀

[@markcole6475]

Side cutters are top of the line puncturing equipment!😂

[@DirtyPlumbus]

Good to see you back. 👍

[@JBRider]

Your a great man Raz, and a fast one too

[@mikeinvegas1]

Loved the video ❤

[@M4A2Master]

We used to shoot our old/bad lipo’s with incinerating tracers, lit them off beautifully and gave a nice show 😂😂😂

[@makestuffbetter19]

Fun fact. Rlarrlo stand’s for, Relax Warm Love.

[@Steelythestacker]

Triple Deuces! Get it!

[@boduke9428]

I love the Fireteam. It's my favorite rig in the collection. Not the biggest, fastest, best handling, or toughest but it's the best combination of all those things that I've found. I just beat the snot outta mine today. Huge air, front and back flips to dirt and pavement. Only a pillow ball popped out from hitting a pine tree about twenty feet up with the left front tire. 3 minutes later she was back in action. The small plastic panels are the only negative. If you're running the body then put small washers on every screw holding the body panels to the cage. It'll last a ton longer. I have went thru 2 sets of plastic in a year. Currently have all the stuff to convert mine to a Bigrock body when time allows. Can't wait to see what you do to one.

[@GenX_77]

Thank you for the knowledge sir 🫡 Brilliant video too! 💯😎⭐️

[@micron3268]

Great video Raz!👍👍

[@mattmclafferty6265]

Great Raz, thanks man Hare Krishna 💥💥

[@mathiaschillisplash8997]

Kev doesn’t have a chance😂

[@bigboytoyzrc9258]

Very nice builds🏎🏎💨💨

[@Paul0088]

Boom 🎉❤ epic runs

[@reconrc1787]

First! Always great content Raz. Keep it coming Sir!

[@simonburrows1467]

Fantastic vid, really informative

[@Pablo668]

Nice work as always Raz. I'd be probably too scared to try and puncture Lipo's the size you are running.

[@mikekoutsohilis9091]

Nice pass👍👍

[@MightyCalves]

That trained professional laugh meme got me good 😂

[@andyvonbourske6405]

who needs pinion gears ? even the motors have spur gears !

[@vincenth3037]

Very interesting explanation and analysis

[@johnnychiou0815]

謝謝您非常詳細的解說，要創造世界紀錄的RC CAR ，在多次的運作之後，電機的散熱不良，導致在超高速運作時的，超大電流讓馬達過熱，破壞導線的絕緣保護，造成漏電、以及更多的過熱、並且無法提升極速、還會損壞ESC

[@ryanjohnson3615]

Put those batteries a meter over in the gravel to burn instead of melting holes in the tarmac?

[@joshuacarter2928]

Raz I know you are busy. We love your videos hopefully we get more soon.

[@sheiladavis2304]

Raz your cars are works of art. Everything machined aluminum and carbon fiber zero tolerances. Just works of art plain and simple. The fact that you've raised the bar so far in the last year that a 214mph is a let down just shows how far and fast you've come. I wondered how many runs can you get out of a set of wheels? I thought those batteries were looking pretty plump. I'm glad to see you used professionals to discharge them.😅😂 Also I always wondered, if those are 1/10 scale cars going 200mph plus. If you scaled them back up to full size is it the equivalent of a full size car going 2000mph plus?

[@GulliJ]

9:00 this is why you should never curb too much electrical wires under big Amp They could changes the conductivity, altered phase control, and return voltage generate on a phase to esc. Balancong is essential, differences in length is less damageable than overtuen the cable on itself Big listake here. Playing high amp requires big respect for rules of physic.... especially electrical here.

[@crazylarryjr]

That last of the 4 sounded like a magnet debonded with the shaft, your screwdriver test is how i verified it once on a Lehner 1200 XL 1200 kv motor. I used JB Weld to rebond and never had an issue ever again

[@craigstewart186]

Great explanation, thank you

[@davidturner2365]

Well cool 👍👍

[@ellc.6143]

😂😂😂 Adel really lmao 🤣 😂 😆

[@masjuggalo]

So how much longer till perfect pass releases their own RC car?

[@fpvkevlar8101]

Great video brother 👍

[@cj910]

Please Raz, answer my question about the driveshafts... can you run them in a Kraton 8s and bash them? The normal drivecup are worn out so fast and this bearing solution looks insane!!!

[@barryriffle8076]

I'd like to know how you have your dewalt drills mounted

[@Airbrushkid]

You say toy cars. But toy slope gliders that have no motors are doing over 500 mph!
