So much in this video for a speed geek to look at! I've run a camera with the shell off looking down so I can observe the behavior of various driveshaft mods on my Vendetta. Not sure I can fit a camera in for this kind of view of suspension. I love seeing this! 👍
I love nerdy stuff like this. Thank you Raz! The suspension needs to be really stiff when speed running. And in your car's case, I can say that they're really stiff and well tuned. The whole body has downforce. So, at 100 mph, it started to show the suspension being pushed down a bit. But when it reached 150+ mph, it's really evident that the downforce was acting on the shocks, springs, and even the whole diff box and tower structure.. This is freaking amazing.
I wasn’t even looking at the diff case or tower until I read your comment. There’s really a lot going on there! These speeds are absolutely brutal for a relatively tiny car. Imagine the bumps and the car being increased in scale to 1:1. That smooth runway would look like it had 4in curbs and that car is hitting them at triple digit speeds.
What's even more impressive to me: The Input gear is nor wobbling because of your AMAZING Carbon Fiber Drive shafts! That's my take away from this nice no board shot 🤗😘
That was neat to see! Interesting to note the pebble bouncing around inside @1:20 . Hard to believe the internal air flow was so still at 130 mph. Could be informative to tape a bunch of little pieces of yarn or tinsel dangling around inside the body shell for a view of how the air is moving inside!
Its crazy seeing those foams wear down so quickly in one run! It shows how much powere these little things have! This video is so satisfying to watch all the mechanical parts working, not just the suspension!
Wow…wing mount working hard.can’t believe u caught air slowing fro a hundred, Multiple xxxx.and those drive shafts…look like they are setting still.wow.great car and parts.great vid.ty
Look up "Perfect Pass" and "gyro for rc car". Not that the man's not skilled, on the contrary, but without this technology, such a run would be near impossible :)
Dope video Raz !! Im glad you’re showing people that there’s way more to factor in for speed runs other than big motor and ESC. THAT SUSPENSION IS A MAJOR PLAYER IN SPEED. 👍🏾👍🏾
I absolutely love watching development work and general engineering vids , awesome to see that really really enjoyed it. Hope you share more videos like that
The spring is only one factor of it. In motorsport racing it gets very technical with compression, rebound, high, low speed, etc. Depending what you're doing to achieve the best time are to eliminate as much unnecessary hops/bounce possible. Each surface also plays a huge role in this as well. In the rc world i get most of these are negligible but same concept still applies.
The rc shocks can be tuned the similarly, while building it, once built only preload can be adjusted, and u also get different fluid WTs. Who said any thing about it only being spring 😂
Almost seems like just a hair lighter fluid would suit. But I don’t have to tell you how that’s a double edged blade. I feel that what you are doing here with a more resilient spring has been needed for quite some time. I think the larger diameter material was a good call. As per usual. Happy to see real innovation within our hobby. And thank you for spearheading these leaps in product improvement. Even though I don’t own an Arrma anymore.
That's cool .. I got the monster servo for xmaxx (will it be strong enough? )& have the battery connectors on the way then I can install everything along with widemaxx kit.
Very nice pass. Nice work. Had my old ass 1985 RC-10 gold tub up to 76 one year,,with a 7 cell uber matched SCR sub-c's and a Twister 2wd titan oval brushed motor, Modified Novak 4 with upgraded FET's and lots of internal wizardry to make it more efficient. Super slick (Just released) losi JRX2 body on my Rc-10. Schumacher tires. Ahh, the good ole days. Won lots of mains with that junk, Still have the shiny hardware, and the car with the twister motor and Losi body still in place.
WOW.!! You can actually see the car getting lower as the speed increases. The springs were being compressed & the arms were getting higher & higher. It just shows that the bodyshell & the under body aero are working & working well.! Does anyone know the actual downforce figures a stock Limitless can produce.? I wonder how much this body can produce in comparison.? Another awesome video Raz, thanks mate.

Absolutely fantastic view to see the effects of the suspension at this rate of speed. Im certain those springs will be an incredible buy for anyone looking to achieve that mph and more. Now on to the big question! LOL... When will be seeing the most anticipated video of 2023??
Now that I think of it it's incredible how those small bearings and the drive cups in the drive train can handle such rpms and torque without failing or overheating during the passes, there is so much to think and learn about just by looking inside the car while running!
Changing springs is only a small part of the picture. Changing the "valving discs" in the shocks and oil weight etc is going to play a far bigger role in keeping the tire planted thru the run. But, it's still really cool to see a HD shot of exactly what is going on at 180+ MPH in a RC car. Still wild to think RC cars are going in excess of 200mph!
Impressive stuff, this just proves to me that aerodynamic forces are so great as this speed that the suspension is being fully compressed. The system will react positively to the adoption of a heave spring or third dampener. This will allow the heavy spring to take the aerodynamic loads and leave the suspension to deal with the car.
That's amazing. I can't wait to get my hands on some of these springs. But here in South Dakota it's ❄️ and cold. But come spring I want to hit 160 at least the summer.
Raz this is awesome. I watched it 3 times man - please do more like this!! Now let’s get serious, we need a similar camera angle on one of Kev Talbots cars over that skatepark 😂😂
Man looks like you could see the A arms flex wonder if some aluminum or titanium arms would be beneficial in a speed run with your springs raz? Awesome work 🔥💯
I concur with your comment. The springs were so tight they were not really doing anything apart from hitting the largest bumps . All the wheel movement is coming from the 2 tips of the arm and possibly the shock tower flexing . I would test a metal arm and a softer spring .
I saw that James McCoy used aluminum arms in the rear of one of his fastest cars. I wonder if it was for this reason. I put the carbon fiber inserts in the rear arms of my Hoboa VTE2 for this reason.
Seen so many full sixe cars with this angle seeing it in this scale really there's no to little difference except weight brilliant shots mate keep at it. Don't you get alot of cracked rims on tyres so low profile?
This is amazing sir u have went above and beyond in my opinion much more then others will ever think of !!!! That’s for sure ❤🎉 also when will this be on amazon ?
I'm sure you have a good reason like warming up the batteries or something but why doesn't somebody get in a car and drive it down the airstrip that way you can preserve the top voltage of the batteries?
Love the angle, you just need to teach Kev how to get that angle. Just need to see how they shatter in half when landing after a full send to the moon.
It’s Amazing that the small hub bearings do not fail at those speeds. I would look at custom hubs with larger diameter Bearings.I think at those speeds everything need to be bigger really. I would maybe try a 1/5 based starting point. Don’t know if speed cars are done in scale classes ?. Also that bottom plate is basically giving 0 droop to the arm over bumps but maybe it’s necessary to have it.
Would it make sense not to paint the body so you would have more light for the filming so it wouldn't be as grainy especially when doing high framerates, also probably wouldn't blow out the brighter areas as much.
Everything You Need Is Here..

Dude there's so much to learn from the insides of an RC car at 180mph, this is going to be such an undervalued video by the internet. Love this.
Yeah legit nobody asked for this but it’s what we all needed to see

@@MustangsCanTurnToo agreed brother. What's crazier is the scale speed of this is like a rocket ship for such a small car. 1200 mph (2000 kph)!!!
I think the camera is just shaking at those speeds, not the diff box. That would be fatal for the drivetrain because of the clearances
What's even more impressive to me: The Input gear is nor wobbling because of your AMAZING Carbon Fiber Drive shafts! That's my take away from this nice no board shot 🤗😘

that's a great idea. Dental floss?
the body masks out the air like a lmp car, barley any air gets inside the body
Its crazy seeing those foams wear down so quickly in one run! It shows how much powere these little things have! This video is so satisfying to watch all the mechanical parts working, not just the suspension!
Raz if you have a video of the stock suspension, a side by side comparison of both springs would be great.
That’s crazy seeing all the parts not just the springs but the towers and chassis brace move under load, the foams didn’t lift!! Nice job Ras and PP!
This is freaking awesome. I'm not sure if I'm more impressed with the video or the sound this thing is making 🤣
Awesome footage. To see the CVDs spinning at those speeds is just mental.
Raz the suspension shot is one of the absolute best ever
FASCINATING! The stuff you do is next level man. Seriously, you're appealing to intelligent RC'ers. Not the smash and crash donut eating crowd.
Great vid bro 👍 it’s amazing seeing everything at work
I'm going to be rewatching this a lot. So many things to try and focus on in one shot! Thanks for sharing Raz!
Now your talking! I love to see this sort of content, Brilliant video👏👏
Wow…wing mount working hard.can’t believe u caught air slowing fro a hundred, Multiple xxxx.and those drive shafts…look like they are setting still.wow.great car and parts.great vid.ty
How the hellll are you controlling that?! I can't believe my eyes. What a performer, and what a performance! 😬😳👏🏻
Look up "Perfect Pass" and "gyro for rc car". Not that the man's not skilled, on the contrary, but without this technology, such a run would be near impossible :)
That suspension footage was amazing. I enjoyed seeing that.
That was so awesome!!! I love the view from the inside!!! It's like we get to ride along with your car!!! Pure awesomeness!!!
Great to see how it all moves under the load and speed... Brilliant Raz 👏
Dope video Raz !! Im glad you’re showing people that there’s way more to factor in for speed runs other than big motor and ESC. THAT SUSPENSION IS A MAJOR PLAYER IN SPEED. 👍🏾👍🏾
i dont do rc stuff, but yesterday i was watching videos of some and thinking of wanting a video exactly like this. thanks!! so satisfying for me
So dope, Raz. Love this view. Imagine getting a thermal imaging camera in there. 🤯
The suspension shots were great. Looks pretty good to me. Love how stable the platform was at speed. Quite well tuned shocks and springs. Nice car.
One of the best RC videos ever!
I absolutely love watching development work and general engineering vids , awesome to see that really really enjoyed it. Hope you share more videos like that
Wow!!!! That suspension looks seriously controlled and tight!!! Great video sir Raz!!!!

The rc shocks can be tuned the similarly, while building it, once built only preload can be adjusted, and u also get different fluid WTs. Who said any thing about it only being spring 😂
the shock is very important in elimating bounce, ths shock converts energy from the shock into heat enegery which dampens the bounces
Great video, it's nice to see the work behind the speed run at hight level
Phenomenal footage Raz, thank you
what did i see? A speed of 180 mph? That's amazing.👍👍👍
Wow! That was an awesome sight going on in there Raz👍🏻👍🏻👏🏻👏🏻👏🏻

What an incredibly beautiful machine! It's so nice to watch this thing work..
I love the sound
So much needs to be in tune to make these cars that fast, very nice Raz...
That's cool .. I got the monster servo for xmaxx (will it be strong enough? )& have the battery connectors on the way then I can install everything along with widemaxx kit.

That video is fascinating Raz. I didn’t spot any wheel bounce and the whole structure looked stiff around the spring. Super impressive mate
Fantastic videography!!
What a great footage ‼️Amazing 👍
This is awesome..like to get into speed runs …perfect teacher
WOW.!! You can actually see the car getting lower as the speed increases.

when it passed you it sounded like a v10 f1 car AMAZING
The suspension seems pretty well damped. No wierd motion over bumps. Good stuff.
😂 that blood splatter on the ground at @1:14 where the 1st camera dude was standing
Thumbs up to the camera man and it all efforts 🥵🤣
I love inside onboards! You learn so much of them!
@razshifrin- O my god!!!! How cool!!! I'm texting you RIGHT NOW!!!
Looks to have good contact with the road, thanks for the video. :)
That's amazing. I can't wait to get my hands on some of these springs. But here in South Dakota it's ❄️ and cold. But come spring I want to hit 160 at least the summer.
Insane Buddy INSANE! Freakin so cool!👍👍 can’t wait to try a set of them !👌🤙👍👍
What a concert in motion! A symphony of parts. All coalescing to make a demon of speed played in B#1 😉. ❤️🤑🗯
That’s a pretty sweet view brotha! 🤙🤙🤙
@Raz Shifrin when will the infraction carbon fiber kit restock ?
That was pretty awesome.
Would be great to see a fisheye lens view from the back of the car, like just behind the spoiler while at speed. Impressive
Raz this is awesome. I watched it 3 times man - please do more like this!! Now let’s get serious, we need a similar camera angle on one of Kev Talbots cars over that skatepark 😂😂
It’s getting it now 😂 it would be interesting to see how long the camera stays on
Very interesting
You can actually see the downforce be applied as the car increases in speed And the suspension compresses
Absolutely incredible stuff
通過時はまるでCGのようw
実際のサスペンションの動きはもっと機能していないかと思ってましたけど、思いのほか理想的に動いてるんですね
セッティングの素晴らしさもあるのでしょうが
タイヤ接地面の変化も視認できて素晴らしい映像でした🥂
Perfect Pass drive shaft never moved!!!!
Very very cool! Would be interesting to see a relative comparison between a stock and pp spring!
Lotta play from that upper control arm. Its also interesting how much everything flexes.
Man that's impressive!
Dialled and stable at such speed!
Man looks like you could see the A arms flex wonder if some aluminum or titanium arms would be beneficial in a speed run with your springs raz? Awesome work 🔥💯

Wow🤩 amazing how stable the chassis stayed.
What an amazing camera angle that was 👍
That was awesome. So much down force at high speed
@razshifrin- no number
Hello, Nice video great perspectives!👍
I believe that rear droop would eliminate some of the suspension play! what you think raz?
I was expecting more fire :) good job!
I'm sure you have a good reason like warming up the batteries or something but why doesn't somebody get in a car and drive it down the airstrip that way you can preserve the top voltage of the batteries?
Awesome vid my friend!!
I gotta ask, what kind of receiver you use that let you get so much range? I NEED to be able to go further lol. Plz Help
Intense. Great view of the workings of the suspension
Do you sell springs for shocks 🤔
very cool camera angle 💕 science
Great video 🔥🔥🔥👍🏽👍🏽
It nitro tubing still necessary when using the pp springs?
Love the angle, you just need to teach Kev how to get that angle. Just need to see how they shatter in half when landing after a full send to the moon.
I’m guessing your perfect pass springs are different front to rear, ie more progressive on the front to take the extra load
Love being able to see how much the downloaded compresses the springs
It’s Amazing that the small hub bearings do not fail at those speeds. I would look at custom hubs with larger diameter
Bearings.I think at those speeds everything need to be bigger really. I would maybe try a 1/5 based starting point. Don’t know if speed cars are done in scale classes ?. Also that bottom plate is basically giving 0 droop to the arm over bumps but maybe it’s necessary to have it.
Shows how important and active suspension is, even when the road looks perfectly flat.
Visual analytics, me likey! Gone bananas foams?
1:12 like a Rocket 😂
Would be nice to see the comparison between different springs
Millions of views…incoming😊
Awesome
Hahaha, sounds like a mini F1 at a high pitch scream in passing .
Would it make sense not to paint the body so you would have more light for the filming so it wouldn't be as grainy especially when doing high framerates, also probably wouldn't blow out the brighter areas as much.
Great ideia, great execution!
