Default S4 weight distribution

Does anyone know how the S4's weight distribution compares to the Durango (or Aero)? Any CAD simulations made?

And how is the S4's weight distribution compared to the BJ4?

Furthermore: is the S4 as good at the XX-4 over rough terrain?

(if no, it's possible to simply measure the tyre loads on digital scales front & rear)

Also some comments on the COG would be nice...

I think the S4 is slimmer than the Bj4 WE, and also more compact, everything is closer to the center line, so the weight distro is aligned lcentrally.

Agree, must be ideal. The S4 looks at it also has the weight more centrally placed than the BJ4, but not as much as the Durango though.

Btw where did you get those rear shock covers on your proto from? Part no. and link to webshop?

I sold them through my online store. PM me for me more details, as I still have some left over. I have them for the B4, T4, GT2, GT, and also the Revo and Jato.

The weight on the S4 is more central both width ways and length ways compared to the BJ4worlds. From my experiance it results in quicker direction change and allows you to carry more corner speed without the car pushing wide.

Having not driven a XX4 I can't comment on the bump handling but seeing them race together I can say that there is very little to choose between the two.

I can try and get a front and rear weight balance later this evening, at a guess I would say around 60/40 rear to front.

@jcb: excellent! Look forward to knowing more!

The "secret" of the XX-4 is that the fact that the weight is more forward? (compared to BJ4 for instance)

Atomic really makes good stuff, that S4 carbon tub is a piece of work Would they consider selling a complete car?

How do you view the Aero compared to the S4? Has Atomic btw considered the same battery layout? (can't get any more centered than that)

With a low & centered mass it should roll less yes. Is it also less prone to flipping over then?
