I just changed to losi white & black springs and the car has become more aggressive... I like it, but I would like to tone it down just a hair...

*adding*
plus, I just got the car and I am playing with the setup..

I'm not sure what a losi white and black are in terms of weight, so I'll just say this.... which you probably already know, but...

Typically, the softer you go on a corner, the more traction it will have. It's allowing more weight to transfer to that corner, so that corner sticks a little more.

You also have to consider what you want the car to do.... less agressive off power? on power? neutral power? ... I could go on....

Edit:
If you like the idea of running a swaybar, but want just a slight change, run the smallest wire swaybar in the front of the car. that should tone it down a little.

'das cool. Everybody's got to work ideas out somehow!!

in your case, go softer in the rear.

Oh and one more thing...
If you are going to be switching between spring makers, do yourself a favor.....and stop.
I've noticed a difference between a 20lb losi spring and a 20lb AE spring when they are on the track. It's got something to do with the spring material and the way they are manufactured. The losi's feel slightly more progressive than AE springs do.

Either that, or, go to each manufacturers site and get the spring weights for each spring you have. That way you are at least in the ballpark as far as weights go.

Good luck tuning and testing!!!

I am moving towards KevinK's setup and he listed either HPI or Losi springs... never used AE springs before, thats what was on the car when I got it...

Yup, just going to change things and see how they work or don't work

i appreciate the info

Default Toe in/out

This is a little off topic, but I figured while you were on the topic of set-ups:
What is the difference between toe-in/toe-out. I know how the wheels angle and stuff, but what does it do physics-wise to the car? I've messed around with it a little bit, and I tend to like toe-out more, but since I don't know anything about it, I don't know why. Thanks in advance, sorry for barging in like this.
-Josh

Quick and dirty:

Toe-out tends to give a more steering and will cause the car to wonder on the straight a little.

Toe-in will make the car a little easier to drive and track straighter...

Most run from -1 to +1, to much in either direction will do some strange things.

It can be a good tuning aid and quick fix.

off the top of my head,

Front Toe-in: more stable, less steering response, more mid corner steering

Front Toe-out: less stable, more steering response, less mid corner

For dialing in a car I play around with the bigger things such as tires, springs, droop, caster, oil, shock mounting positions. Toe-in shouldn't be the top priority when you are thinking of changing the setup. I always keep it at 0deg and only change it if it's necessary or for fine tuning.

What he said. It's a last resort adjustment in my book.

I thought swaybars were. Have I been misled?

Does anyone know what the different ackerman positions do? Is the stock setup in the middle or at 1 end of the scale? Which hole do you use for the most effective ackerman and for the least effective ackerman?

Thanks,

Steve

Nexus, thanks for the information, what I actually meant was which postition on the steering plate for the Pro 4 will give the greatest/least askerman affect.

Skill The following was posted ages ago on this thread

Ackerman

The settings go in this order from most aggressive feel to least aggressive: 1, 3, 2, 4. 1 and 2 are with the slanted edges of the plate facing forward, and 3 and 4 have the slanted edges pointing to the rear. The main difference is that 1 and 3 have a lot of initial steering, but 1 has more steering at full throw. 2 and 4 will calm down turn in quite a bit, possibly even causing understeer. The 90 degree arm is just an extra part on the tree, so that that plastic mold is more versatile (as in if we decide to ever turn the servo 90 or something similar).


This cleared it up for me.
