[@johngarner3499]

nice vid man best rc car vid i seen by a long shot.

[@traxxasrockhead]

thanks man

[@chrisproenca6432]

Ha ha love the little audio easter egg at the end of the video 🤣

[@traxxasrockhead]

yeah, I thought it would be fun to include. 🙂

[@albrenes22]

lower music alot or just turn it off please

[@traxxasrockhead]

i wish i could. once it's uploaded it cant change.

[@nateemmett4485]

This was really really good, thanks man. Ive been asking these question around the track no one has been able to explain how its working just what the adjustments do. Thank you keep it coming. Sub'd

[@johnsargeant2041]

Man THANK YOU for that explanation.. And wording it that way.. That jist helped me so so much.. I may not be racing, but for me... Driftting suspetion set up plays a big roll on making the car do what u want when u want. And the roll center is were my problem is.... Cause i understand other aspects of the way it works. But by bring them all together is what will make it work. Agean Thank You.. Peace

[@traxxasrockhead]

i'm glad i was able to man. after making more videos i realized how long this. if i was to remake it i would make it a lot shorter

[@johnsargeant2041]

Wasnt to long for me.. Made sence in an easyer way.. Havnt had a chacne to mess with my car. But will soon enough.. See how much of a difference it makes. I kmow its in the rollcenter of both and front and rear. Cause iv done made adjustments on everything else. And still wasnt consistent.. Thank u agean.

[@eastermister1]

Would have loved to watch this video too bad there's so much 90s techno going on

[@sykotcr1]

its actually techno from 2015 ;-)

[@halleffect1]

I'll have to watch a few times to get it. thanks for making this video.

[@traxxasrockhead]

halleffect1 no problem, I'm glad it helped you

[@matthewclay4446]

wow thank you man I just found some of your videos for the first time today and I found another guy right before you today and you two guys by far are the best I've seen explaining the stuff in a long long time so thank you and keep up the good work you've taught me a lot

[@traxxasrockhead]

matthew clay thanks man. I am glad you get something out of them

[@ukandrew]

Cheers. Very helpful Evan.

Awesome mate that is one of the best ways I have seen roll centre explained all your videos in this series are helping me so much!

[@traxxasrockhead]

Dallas Skeer awesome I'm glad you liked the series^-^

[@dallasskeer2418]

Do you have one on how to set steering end points?

[@traxxasrockhead]

Dallas Skeer check out my Setting Up Electric For The First Time, I go over end point adjustment. kzbin.info/www/bejne/lZ3YZpyOjbqcg8k

[@dallasskeer2418]

Awesome love this channel even more thanks so much mate

[@walala9885]

do you have non-music version?

[@traxxasrockhead]

no sorry

[@i.p.outdoors3825]

if you lower the roll center on the rear, should you also lower the front?

[@traxxasrockhead]

not necessarily, you can adjust them independently

[@S9RUT]

What would you recommend for a HPI E-firestom Flux for front and rear?

[@traxxasrockhead]

it's hard to say. each car is different and the feel that the driver is going for is so different.

[@MrBrinkman721]

very helpful video man sat at my local track yesterday for 5 hours dialing in the car and watched your video twice to help with some traction roll issue i was having. helped alot still have a little traction roll but our track is very grooved so i will just have to keep the speed down alittle.

[@traxxasrockhead]

MrBrinkman721 wow, that's awesome to hear. I'm glad I could help and that you understood it ^-^

[@mixpcch1738]

this vdo is very useful for me . thanks !!

[@traxxasrockhead]

no problem, I'm glad you found it useful.

[@neiloliver7950]

Thanks but please lose the music. So annoying!

[@traxxasrockhead]

Thanks man. Unfortunately the music can not be changed and keep the voice over once the videos is uploaded. Sorry about that. I would use a different song if I had made this video now.

[@puguglypg]

Great video man, so if I raise the arm hinge pin I raise the roll centre because the instant centre raises up. Is that right...?

[@traxxasrockhead]

if you raise the hinge pin that mounts to the chassis then yes, the would be raised

[@mathias4891]

*measures and calipers .... how i do when those two 'lines' actually move slightly apart? Du wat?

[@traxxasrockhead]

hmmm... i'm not sure what you are trying to ask here.

[@gatorage850]

@@traxxasrockhead not 100% but, I'm sure he just asked, if the hub pivot points are close and the diff pivot points are separated? the line would never cross! this is if he had his dog bone level.

[@gatorage850]

@Matthew Seger Roll Center is always moving, the measurement is really not the importing thing. but, ""at arm level"", if your upper link is pointing down (shock tower to hub) you have low roll center. but this is only low roll center at ""arm level""l!!! this mean at ""arm level"" in a turn, your outside arm (hub) will try to lift (less pressure on the tire) and your chassis will go down. to get the weight on (tire) you will need a stiffer spring or swaybar. (if you're trying to add grip).

[@wasabithegosu]

what song is that in the background?

[@traxxasrockhead]

Erick Garcia alen walker fade

[@jammindesigns7135]

Hey what camera are you using?

[@traxxasrockhead]

canon 60D

[@JimmyKay1976]

How does ride height factor into this? Great video!!

[@traxxasrockhead]

I'm not totally sure but I do know what I explained was a static illustration and when you drive the car some of those points are changing

[@inactivek730]

If you lower the ride height, you lower the CG. And vice versa. You generally want as low CG as possible so that the car doesn't sway side to side too much. Just think about monster truck and sport car making turns and you will know. As you lower RH, you lower RC too. The only reason that prevents you from lowering RH a lot is the bottoming of chassis over jumps or turns. So too low RH will bottom out chassis which throws off handling and too high RH will make your car drive very unstable. Provided that your car doesn't bottom out while running on the track, run lowest possible RH (CG).

[@jasonvicars226]

Lowers center of gravity. Always set ride height first then droop then camber and so forth. Roll center should always be done last if possible. Shimming the hinge pin blocks to adjust kick-up or anti-dive. When i was racing touring cars regularly, i would typically adjust roll center only when racing a different track surface. Asphalt vs carpet. Have fun. Nice video.

[@seanbarton8852]

Thank you so much!!!!!!

[@traxxasrockhead]

Sean Barton no problem👍

[@bartgrider6895]

great explanation but why in the world are you running the rear mount in the plus position with +4mm under the ball stud. I would assume you are running on carpet by the tires. I would think you would want the mount in the minus position with no spacer to create a high roll center to prevent traction rolling??

[@traxxasrockhead]

Bart Grider you are correct. After I made this video I changed my set up to 0 spacers on the rear

[@sufiyanahmed2098]

Thanks bro this going to help me in paper and i even liked tune can u plz name the tune

[@traxxasrockhead]

i'm glad it could help. the song is Alan Walker Fade

[@nateemmett4485]

Now how does the length of the link fit into all of that?

[@traxxasrockhead]

it does not

[@traxxasrockhead]

the length of the camber link set how much tire is in contact with the surface, which you may want more or less depending in the track conditions

[@nateemmett4485]

Well with camber at the desired degree, the length of the link would be effected no? Say inside hole on Chasis to all the way outside hole on hub, or both studs on inside hole. See what I'm saying.

[@traxxasrockhead]

+nate emmett I don't really follow. but if you are asking if the camber of the tire will need affected than yes. if raise the ball stud, your tire will gain positive camber. I think I miss understood your first question

[@nateemmett4485]

+traxxasrockhead I guess the best way to word it is does the length of the camber link come into play at all at the same Camber setting.... ie with the ball studs moved as far away from each other as they can be -1 degree camber vs the ball studs as close as they can be at -1 degree camber

Are u still at rc madness or na?

I've been meaning to make it out there I just haven't yet. Are you a regular?
