This is 100% BEST use of a 12mm. And one of the greatest suspension geometry videos on the interwebs.
Damn straight
I am sick and tired of rebuying 10mm wrenches and sockets. They always go missing.
@@thefunniestfarm4731check your boxsprings. youll find one there.
12 is really great if you work on Asian vehicles
An rc video that explains suspension better than any real vehicle video I have ever come across ! Ty brother , appreciate this . Well done .
also find it better then a video just show a dragcar wrincle the tires and say this is anti squat but not realy explane why.
this video the other hand show how it works on a easy level to understand it.
I always go to RC videos to learn suspension. They always seem to explain and demonstrate it better
Absolutely the best demonstration of proper chassis setup to date.
Absolutely, without a doubt, hands down the best demonstration of drag suspension, well, really suspension in general! Thank you
Thank you!
Add a front suspension tuning video for us as well as how to deal with a chassis thats twisting out of shape, and we will watch them. We have all seen unlevel wheelies as one side of the chassis squats while the other side lifts. We appreciate any info that helps keep our rides performing consistently. This is an excellent visual of the homework that I'm catching up on. This beats learning the hard way by eating a wall👌 You earned a subscriber with this
What a great video. I’m an engineer and have often wondered how the suspension linkages worked on drag cars actually worked. Your video scratched that itch and was exceptionally well explained. Loved the use of the model car linkages and applying forces to them. Wonder no more! Thank you!
That model turned out sick. Shows the coolest way possible to explian and demonstrate how suspension works.
I've been trying to wrap my head around instant center for too long. This is by far the best explanation I've found. The part about the pinion climbing the ring made something click for me. When you demoed with the 12mm wrench it was cemented. Now I finally feel like I understand the basics of 4 link suspension.
Thank you.
Absolutely love the video; thank you for taking the time to make it! 4 link geometry is something that I've tried really hard over the years to wrap my head around and this video does an amazing job explaining the key points with real world and scale examples.
One thing that I don't see talked about very often is the front suspension on front solid axle rigs like Monster Max. I run RC rock crawlers and race RC Monster Trucks that use full 4 link front ends and I've had a hard time learning how the instant center from the front links interacts with the instant center of the rear links.
i'll play around with some stuff and see about making one!
Best explanation video out there for the visual learners like myself.
Awesome video! Others have already said it but this is one of the best demonstrations I've seen on suspension geometry! Excellent work!
Bloody brilliant explanation of what’s going on during all these crazy launches we all love to watch.
Just wow we need so much more of this please make this a series!!!
Man, you hit the nail on the head with this video demonstration.. using the slash was an excellent way to show the setups in action as well.. if I had a nickel for every time I tried to explain to someone what instant Center was and how it affected the chassis I would be filthy rich from now on I'm just going to send the link of this video to anybody that ever asks again! Great job brotha! 👏
Thanks man!
I'm definitely sending people this from now on instead of trying to explain suspension physics.
This was so educational! Great stuff dude!
Insta subscribed after watching this!
Keep making content like this! Share the knowledge!
What a great explanation. I'm building the parallel 4 link on my 49 Chevy right now and I was curious of exactly how the car acted by moving the top bar up or down. So cool, thank you.
Very informative.
We need more videos like this
That was pretty amazing intro to suspension geometry. Nice work Ry.
Wow just like all the other comments about your explanation I have to say I’m genuinely impressed with how well you presented this. I had no idea that much thought went into suspension! You earned a follow from me! Thank you much
Great video, very cool to see the scale model examples! Well done
I’ve watched numerous suspension videos but yours is by far the best explanation of how it all works in the real world. Cody needs to watch it.
Jason, rookie drag car builder, UK.
Now Logan needs to give us his version 😂😂😂
Bad ass video. Keep the knowledge coming.
Curious to see how this would run in an actual rc drag race lol. I love drag racing but never got this far into it. I'm big in the rc hobby and we drag race all the time. I watched a bunch of videos about RC drag setup but nothing like this. This was really awesome to watch and appreciate the amount of time you put into it.
this video was put together extremely well great job! Best explanation on the internet PERIOD!!
Great video, bud!
I’m thoroughly impressed
This video is awesome! I wish I had teachers like you when I was in school. If you keep explaining car stuff like this I think this channel could blow up. Definitely got my sub, for what its worth, and thanks for the info.🤙
Thank you! Let me know what else you want to see!
@@ClapdOut for me as a road racer, more to the fact racing off road rc cars 2wd IRS suspension im try to understand how to use rollcenter anti squat long or short links when and why.
not sure you can do a quick and understandable video about that subject?.
can say a learnt some about squat and anti squat from this video that can somehow be used and understanded eaven for a independent suspension tho its a bit different way of achiving the result.
Very cool explanation. The RC car demo's were cool to see vs. just lines on a chart or a sketch on a white board.
I'd love to see even more demos like this for sure!
Definitely taught me a ton about drag racing and suspension. Thanks! When I get to the RWD stuff I’ll be sure to revisit this video!
Man I learned a bunch about suspension that I really needed to learn. Thanks. I’m getting a battle ready 8.8 from Tin soldiers, and a merillat torque box kit for my fox body coupe. There is gonna a lot of adjustments in my future!😂
Thanks man, that made a lot of sense. And that is pretty sick model. You got going there too.
Great demonstration
Make a video of the Rc car in testing been thinking of trying something similar.
Thanks for the lesson. Learned something new
Awesome video explaining the bar angle mysteries!!!👍👍👍👍👍
Ty man, this was video that ive been wsiting for
This is one of the best visual examples of squat and ant-squat. Thanks!
Brilliant explanation! Logan is the beauty and Ry is the brains . What a duo!
This was an amazing video and so well explained
Extremely great video! We would love to see slow motion of your rc drag in action under its own power with the different link angles too!
Very cool demonstration with the RC and suspension adjustments 💪🏻
This is the clearest explanation I've ever seen. THANK YOU.
You did an excellent job of explaining what's happening with the suspension my friend
Sensational video mate, thanks
Been wanting to make one of these but functional! Well done!
I learned a lot thanks man. definitely subscribing :)
This is the best video and explanation to understand this that Ive seen in my life 🤯 now I need that demostration toy, totally should make them for us nerds to play around with the geometry
i may look at 3d printing "4 link calculators" that you could plot and play with on the bench...
Thanks a LOT for doing this, man! I've been teaching my ex-brother in law slowly (but surely.. lol) about race cars, as he wanted to learn and get involved. We've been approaching the suspension subject lately (and in particular, squat/anti-squat) Now I can play this vid for him and watch along so he "gets it"!! 😁👍
...btw, as an owner of 2 DR10s (one being a balls to the wall 2.5 - 4.5 turn powered, no cost spared "money pit", and the other, a 13.5 "super stock") , I feel your pain about the IRS!! I so wish they had solid axle rear ends, instead! That'd be SOOOO much cooler!
Interesting stuff. In '65 I used to hang out at Goodies Speed Shop where Jim Liberman worked building custom gas-welded headers out of U-Tube bends for $125 + $1 for the tube cutting wheel. In any case, he also fabricated "lift kits" for street rods and also employed a lift kit for the '65 GTO funny car Brutus. I became a crewman and always marveled how Brutus would leave the line by lifting its rear and planting the tires into the asphalt Jim was a pretty smart guy at a very young age....kinda crazy too, but very intelligent.
great vid bud. keep it going
Nice work Ry.
Lots of fantastic info presented in a way that lets people digest it as easy as their favorite crayon. Thank you
Great explanation. Cant wait to see the rc car work. Im working on scale rc built similar but dirt late model.
Best video I have seen on this! The model is sick! Really well done and then to prove it on Whistlendiesel is just the icing on the cake!
I never understood track prep, you alluded to some of this and it helped a lot. My question is why do radials and big tires compete at the same track like in sick week? Shouldn’t it be prepped for the tire? Also street tires ruin the prep? Why can’t they run in sick week?
They TRY to cater to both types of vehicles. They try to run slick tire cars before they glue the hell out of it for the radial cars. So it is tricky to have a track that works really well for both. The street tires aren’t allowed because they wreck the starting line. Hard compounds and tread will dig and rip the rubber off the racing surface like a cheese grater and all that debris ends up on the track, under the tires, and you have a really crappy starting line for anybody.
Your best video ever Ry.
The best explanation I have seen yet
Nice work!!
Quality explanation of how 4 link works. I'm confident I could apply to a top fuel team right now.
lol. Well that might be a tough sell as top fuel cars don’t have suspension.
Killer job of illustrating these concepts
This is the most informative Motorsport video I’ve ever seen
Great video bro!!
Great video and instant subscribe
This video is very well done and informational. Thank you for this. Monster max is built more like a rock crawler than a monster truck. Plus that voice-mail was fantastic 😂
Dude this was damn good. And with the RC car that made it even more understandable. Not gonna lie. If I get back into RC stuff and you made a sold axle conversion. I'd buy it.
This is the coolest shit I've ever seen, this makes it so much easier to understand suspension tuning!!! Thank you!!!
This helped me understand suspension a lot better
It's funny how much traction control and tire technology has changed suspension set up. I was lucky enough to have had a few conversations with Pat Musey and Toni Christian back in the day that blew my mind. They were way ahead of the game back in the 90s.
Musi vs Christensen was one of the best rivalries in racing g.
Enjoyed the video. Whistlin diesels truck was a limiting strap failure. From what I remember ratchet straps were holding it together 😂. They fixed it with proper straps now
Awesome video sir
Back in the day (1980’s) we used to run a lift bar in a dirt track car where the axles were full spool.So the rotating force went forward along beside the drive shaft to a single compressible coil over shock absorber. It had the same effect as anti squat. In the interest of weight we also only ran three bars two lower one upper as the axle was not housed in a casing. Think sprint car quick change rear axle. This system would also create the effect of trying to push the axle into the dirt but basically lift the whole rear of the car.
Yes! I’ve always thought it was rad!
Great info!
Very good video, thank you.
That’s badass you made that!
This is the best ever suspension video, remember men are visual learners.
Really good vid........really nice to see it work on the rc car!
Awesome video! I was always curious on how a dirt track modified/late model 4 link would work in drag racing. I would love to see if you could replicate that. Using bearing bird cages and a pull bar or torque arm with negative instant center. Let me know if you can do that. It’d be cool to see the difference on how the tire is planted.
Simply phenomenal
Thanks Ry!
Such a good video!
Damnit man thanks for that it absolutely helps. Now I have some things to think about. Also that has got to be the funniest outré yet.
Curious to how this all works with leaf springs or what’s the differences? Also is there a big difference if your top bars are mounted to the carrier and not in line with the bottom bar mounts?
I’d love to see a full build breakdown video when you finish this rc car. I race rc but I’ve never wanted a rc drag car until seeing this build
I built it solely for static demonstrations but the response to the video was crazy so I’m going to make it functional we will see how it behaves
This a good one here💪🏾
Killer video!
Done did science good... Thanks for the visual representation. Been trying to wrap my brain around this for awhile. P.S. Thanks for pronouncing height correctly.
Dirt cars have been separating for years. They now have to regulate how much they can. Check out some dirt late models or modifyeds we call it up on the bars.
Great video
Oh yeah. Loved when Vaughn gitten was tri podding his drift car with the same technology.
It appears that the big tire car's squat, but they're actually neutral. It's the sidewalk collapsing giving it optical delusion . Radial tire have to separate they have to drive over the instant center, keep the nose down. I actually watched the video today. I can't believe you used Dillon Voss LOL to show tire shake that is awesome.clutch car can be tuff.. Trying to figure how to get my IRS RC car to separate hinge pin angle seems to help a little bit.
Great video!
Glad you enjoyed it!
You should do another video, but test ladder bars and leaf springs and leaf springs with caltracs/assasin bars!
You missed the gasser suspension setup..
Also, I happen own a 76' Plymouth Fury, she has at least 3 different sizes in 2 standards of measurements mounting everything. I have to have a 6.5mm, 3/8", 11mm, 12mm, 1/2", 9/16" and 5/8" wrench just to change my mind. Hell my belt tensioner requires a 1/2", 5/8, and 12mm to unlock and adjusted with a 8mm...
I miss my 94' Impala with a 10mm, 13mm, 14mm, 15mm and 17mm to strip her down to a rolling frame. She was so easy to work on, she removed her own drive shaft and rear axel once. Taught me about drive shaft loops also.
if you have a leaf spring car/truck, with caltracs. how would you determine top bar angle without any? maybe something to do with the spring acting as a top bar?
really enjoyed the video, alot to take in, will need to watch it again. thanks
cant say i can calculate the bar angle of a caltrac suspension but how im understand the function its like the radial setup shown in this video that the rear whants to be lifted and pushing the tyres down, the shorter the bars the faster the effect of the lifting force.
the same is for slapper bars to use the torque from rear axle to react aginst the body of the car to push down the tyres.
@@extec101 the length isn't so much adjustable, you preload or have a gap. But the angle can be changed, steeper or flatter...this angle must somewhat change antiquated percentage but there's no top bar... if that makes sense.
When you're explaining the squat aspect, what makes the car stop squating? Is it when the line from the 2 links is at the cog, or do they hit like a bumpstop thing?
They find a point where the pushing force of one bar equalizes with the other. Usually that happens when one of the two reaches a 90 degreee angle with the vertical center line of rear axle.
Thank you for ypur infor .
Another banger!
Very cool video
Freakin amazing. Thanks!
I spent more time on rc than I probably should. Me and my son (12) have had a blast with our rc crawlers, drag cars, stampede, and slash 4x4.....never thought about a 4 link drag car like this, I think would want to put a 1/8 scale brushless setup in it direct drive from the motor shaft to the rear end. I bet it would do 60.....just to see how well 4 link geometry scales down.
Good job
makes alot of sence we race mowers with no suspension so im completly out when it comes to the discusion but when you simulate the changes with your model it makes total sence learn something new every day
Any info on long travel Baja type suspension?
Got a new Sub here.
Great content.
Also..
HOOAH to a brother OORAH.!
Reason Caltracs work so good, they leverage that tire into the track as hard as you want.
