Arrma 6S tuning adjustments guide

[@jimmyjoe1871]

Dude you are the king of RC videos from a mechanical perspective. I probably owe you a beer.

[@JoelMannerino1]

Thank you for the acromin explanation!!!! You're the only person that explains it

[@seanconrad5467]

Great video, thanks! I would love to see a video about setting ride height, shock preload and toe. It would also be good to show common handling problems and the adjustments that you should try to solve them.

[@TheATeam_2014]

This has to be one of the most educational video for this exb model yet... 🤜🤛

[@Firewlkre]

I really appreciated this video, I already had the shocks, swaybar,caster/camber down but up till now hadn't understood or used the roll center or ackerman adjustments.Understanding all these makes rc's even more fun.Thx for sharing your racing knowledge.

[@omarayala1820]

You are the man when it comes to explaining race tuning . Thanks!!

[@jerryvolpini7987]

One clarification about shock location, though. People often say that laying the shock down softens the suspension. While this is true, it only applies to changing the mounting location on the *shock tower*. When laying the shock down on the *suspension arm*, the opposite is true - the suspension gets stiffer because the leverage of the spring on the arms increases as the arm moves upwards. To make it easier to remember, any time you move the shock mounting location inwards, on the tower or the arm, the suspension will be softer.

[@RazorRC]

Yes, very good point. I actually hesitated when I was talking about the shock location on the arm for that reason. Angle affects progressive vs. linear and position (in or out) affects overall softness/stiffness.

[@jerryvolpini7987]

@@RazorRC Sorry, not trying to be a jerk 😁, it's just one of those points that sometimes needs clarification (like my other comment about roll center)

[@RazorRC]

@@jerryvolpini7987 not at all! thanks for providing additional explanation!

[@OldfartRC1]

Great info.. was confused by the video at first...this make more sense 👍

[@RazorRC]

Luigi Bellantoni I have an entire video just on shock location, but didn’t want to spend 10min just on one topic 😀 kzbin.info/www/bejne/opasqIGmpJaXm7c

[@fishininjun]

absolutely learned a lot!!! thank you. ive always wondered but could never find anyone to explain what all the different locations of shocks, etc. were and how it effects driving

[@erichehir9672]

Thanks man I forgot about that and couldn’t figure it out, thanks

[@jerryvolpini7987]

Ok, one thing about roll center. Always think of roll centre as applying to the inner ball stud location. If you raise the inner ball stud, you raise/increase the traction (lower roll center) and, similarly, if you lower the inner ball stud, you lower/decrease the traction (higher roll center). Therefore, the opposite is true when adjusting the outer ball stud (at the hub) - if you raise this ball stud you decrease traction (you are effectively lowering the inner ball stud) and if you lower the outer ball stud, you increase traction (you are effectively raising the inner ball stud). Again, just trying to clarify, no offense intended to Razor RC 👍

[@rosone51178]

I also felt like Razor may have been backwards when he described roll center. I think of it as it's easier to hold a baseball bat in a vertical position the higher up you hold it. Easier to counter the effects of gravity, less roll over, with a higher mount position (inside ball). Higher mount position (inside ball) = less body roll, less traction, less traction roll, and also more weight transfer to the inside wheel. In other words when talking about the rear end, less body roll = more "drifting" = less traction.

[@JustKeepLivingFPV]

This is why the kraton is my favorite basher. So much to tune.

[@MauzyrockRC]

Such an in depth look and description. I just got one of these, and your vid is top shelf! thank you!

[@jerryvolpini7987]

Great video, people really need to understand these adjustments so they get the most out of their vehicle! 👍

Interesting. Must be something in the setup, because I dont really hear of anyone else complaining about this. However, that is exactly what happened when I put stupid power in my Tamiya TT-02. Hit WOT and it would just spin out. I always assumed it was diffing out left-right.

[@Basherqueen]

[@berbandis]

The sway bars help the car stay flat instead of dipping side to side when cornering. Thats why its called a "sway" bar (or more correctly an anti-sway bar). The stiffer the sway bar the more level the cornering as the spring resists any movement from the suspension that is not equal on both sides. This may just be another way to say what you said here but I was not able to understand that from the words used.

[@cripmeezy]

😂 exactly

[@cripmeezy]

I'm not sure if this guy actually this guy actually understand physics

[@RazorRC]

@@cripmeezy Obviously anti-roll bars resist roll. What I did is go one step further and explain WHY the car stays "flatter" -- it's because the two arms are tied together (more). Because they're tied together, the inner wheel cannot lift as easily, and both springs are resisting compression of the shocks instead of just one. Then I explained how that effects driving. What does "more flat" do? -- it results in less traction on that end which will be more understeer on the front end because the car is not rolling as much, and more oversteer on the rear end as it is not able to roll as much.

[@Mechabjornis]

Thanks for the excellent info and presentation, also on the diff shimming-video for the Kraton. (Which I am currently building)

[@jessjoshwyatt3571]

I think running shocks on the outer hole on the arm helps with better stability also. More support further out on the arm.

[@NeighberhoodRC]

I changed the plastic steering knuckles to aluminum on my notorious and get better steering, when u screw the cap back on into the plastic one it can get massed up and mess with ya steering

[@Crispy983]

Another KZbin mentioned that he replaced the shock end cap 3 times before he realized there was a droop adjustment and made it so the shock couldn't bottom out

[@Lord_Pistachio_Nut]

Extremely informative. Thanks!

[@RazorRC]

Glad it was helpful!

[@zeisslersrccars9696]

This is a very nice video about tuning. Thanks

[@norcalrc]

[@ETAI106]

* Stiffering the sway bars will reduce the roll in turns... Less tilt while cornering...

[@RoostedFilms]

Great info and well done thanks

[@EastTactics]

I believe that outer hole on the a arms is actually to allow for those beefy arms to be compatible with the V4 shock tower. So if version four owners want to upgrade to those arms they could. They would have to pick up other things though to make it all work out. For instance they would have to switch from the V4 swaybar to the V5 sway bar

[@RazorRC]

I believe you are right! Backwards compatability.

[@GreatLakesRC]

Sweet! Love the explanation 👍👍

[@cripmeezy]

🤦🏽sway bars literally doing exactly what this description say they are. You also can achieve stiffness I just rotating the screw on the shocks. Changing the shock location does change that behavior but also changes the geometry. If the shocks are changed from their original location Camber and toe we'll have to be adjusted as well. To achieve a stiffer or softer ride you can do so by just loosening or tightening the screw that is on the shock or changing the shock fluid

[@gonzodetroitify]

Awesome Intel inside Razor🤔 my Q is can we use the theory here to apply to another model say talion or typhon 6s tho🏁😎 thank you either way Razor,

Hi, I'm a newbie, I just bought my exb and had my first bad jump and dis-aligned the rear shock tower, and when I disassembled it to fix there's a crack a threaded, my question is how to avoid that and is there any parts that more durable, I think it's a gear box case

[@KTMcaptain]

How much suspension travel does the kraton 6s have? I can’t find that advertised anywhere.

[@mikecabardo]

I want to setup my kraton 6s v5 for street bashing. Do I just lower the ride height thru the droop screws and removing preload on shocks? Or should I adjust shock position as well? I want to do some on-road speed bashes with it. Running it with a 17t and slightly smaller 5inch tall street wheels :)

[@NeighberhoodRC]

Can that front bumper fit on notorious 6s v5 blx ?

[@pdrc9344]

Hi Razor RC, I have bought some kraton 6s shocks to go on my 3s granite. It looks like the springs rub a lot on the shock body and there is a small play side to side from the shock shaft in the shock body. Do you know if I can sort these issue out at all? Appreciate any ideas in advance

[@MrMikebeben]

Good video but completely wrong on the sway bar info. A smaller sway bar makes your front kinda loose and thicker makes it stiffer and what the sway bar does is when the one tire comes up in the corner it pushes the other tire into the turn

[@RazorRC]

I recommend reading this: en.wikipedia.org/wiki/Anti-roll_bar . A thicker front sway bar will tend to make the front understeer, not generate traction. The loaded outside wheel actually causes the inside wheel to not to lift as much, not the other way around.
