Basic Car Tuning
 

Not so sure if this thread is a repeat thread but hope not. Most of car tuning issues was posted in individual car type even it is basic which apply to most of the 1/10 rc car so lets combine all the expert and experience tuning tip to this thread. All for one, one for all!!:D

this is the first basic link of tuning direct to me from AMGRacer almost a year ago.. Basic Car tuning

And this is for the droop, ride height and tweak from Team Lossi website. Lossi XXX web :)

right, there is proper explanation about droop (downtravel).

Spring effect
 

Guys, what is exactly the shock spring effect to our cornering and handling? Heard that the spring get into effect more on brake and cornering !:confused:

Traction Roll
 

Arr..guys, What exactly traction roll is? When we should consider this and how to achive the correct traction roll??

Re: Traction Roll
 

You won't want traction roll. That is to be avoided at all cost ! :lol:

Traction roll is when you have too much traction that the car will flip while negotiating a corner. There are many causes of traction roll. Ride height is mostly the major cause.

Re: Re: Traction Roll
 

OOOoooo:o yup yup too much traction which make the car tend to flip - rolling :smile: That's funny because my first tought was traction roll is how to make the car roll better - forward. :p

Question on condition
On the high speed cornering my car go smooth with quit big turn. But suddenly when I went into tight corner off power abit slower at the mid of cornering my car slip, tend to spin :eek:

:D Don't ask me the setup but what will be the area or tweak that I should look into? Thannnk you :nod:

Re: Re: Re: Traction Roll
 

Perhaps there is too little droop in the rear. Play around with that.

this is some pretty interesting stuff you guys have here

Esham ... try this for starters http://www.donegal.flyer.co.uk/car%20setup%20guide.htm

Understand all that then take your car to the factory setting and slowly tweak one thing at a time and see the difference. What are you driving?

Re: Re: Re: Traction Roll
 

like what initialD said..you might have too little droop at the rear causing the weight to be transferred all to the front leaving the rear end floating and causing oversteering when throtle is released...try putting more droop at the rear or put stiffer springs at the front...if it still over steers try changing oil to a hevier weight to slow down weight transfer or arm travel...

everything is all about weight transfer from side to side, front to back corner to corner of the car...

one more thing, check for tweak...see xxx-s tweaking...

There usually is a thread like this that pops up about once every couple of weeks. . .

First suggestion - get ahold of xxxmain's setup guide. Not only does it explain all aspects of a car's setup, it explains what to do with each thing for whatever is happening. (www.xxxmain.com)

For instance, if your car pushes going into a turn, it gives you, step by step, things to do to fix it. If your car is loose coming out of a turn, these are the things to do to fix it.

I'm not advertising it, and I have the version that was pre-XXXmain.

I just haven't found anything that even comes close.


Now - if you REALLY want some REALLY technical details on things like how ackerman works, how a Centax clutch works, things like that, see www.rctek.com - he hasn't done much with the site for a year, but there is still a lot of VERY technical detail.

Okay, if you're a physics whiz (which I'm not, but I work with some) there's a book that is pretty much the comprehensive work on the subject - "Race Car Vehicle Dynamics" - Milliken & Milliken. This thing has everything you want to know and a TON of stuff that you really have no idea what they're talking about.


But - just get the stupid xxxmain manual. . .it'll help. . .

heres another helpful site: http://home.tiscali.be/be067749/58/

Thanks Boomer, yes I do tried to get those xxxmain manual but I afraid they didn't supply direct to my country - malaysia. 2nd tried they refer me to their supplier here www.tpracing.com.my but yet they didn't order it cause they said xxmain inprogress updating the contents..emmm :rolleyes: almost 3 month now ..no news.. Now.. i asked my friend from Durham to order it for me from their dealer at Chicago.. Hope success! :cry:

Thanks tIANcI, sup ... Actually I did go through the web and the article before. The basic understanding of tweak .. yes I take it. Believe me i do have alot of bookmark to all does tweak on the web.
