Ok, Losi REALLY needs to release new info on this car. We've reached the point where we're discussing subtle differences between the way Americans and Brits spell certain words, for cryin' out loud!!! LOL!

It's nice to have english lessongs on this thread, but can we stay on subject and get back to arguing about the JRXS

"the shorter arms by themselves has no practical bearing on camber rise/gain other than to make changes more sensitive, and very little impact on how stiff/soft the suspension can be. the only 'stiffness' would be the mechanical friction caused by the tire scrub (track width change during suspenion movement) vs. less scrub/long arm, which is mostly negated by the fact the car is in motion with toe typically being ran in the rear anyway."

Roll center. That's the only explaination for the short arms. As my friend Seaball said " the short arms are necessary to get the rc to sink, and the camberlinks obviously need to be even shorter for any type of gain when in bump movement.

if you remember our short arms/long arms thread, something i brought up was that there seemed to be a desirable amount of roll center drop/change regardless of chassis roll. and that cars that don't roll much, still need to produce a dropping roll center durring the movement. huh? was i on to something..."

Heyeva, I tend to think the car will run a softer spring. I really don't know though, since that would be based on the roll centers, the arm lengths, shock mounting, etc.

I am certain that Losi along with other manufacturers will release info and announce cool new things during the upcoming Chicago show.

In the meantime...here's something funny :
Posting and you...

i dont know if this has already been mentioned but hey,

Today i was informed by a very reliable source that there have been infact 3 seperate variations of the JRXS.

The pictures that we have all seen may have been of the first version which could be completeley different from what is being tested at this moment and what will most likely race at the worlds later this month.

Could the pictures we have all seen be throwing us all off the scent? Just a theory


thanks

Looks like the A-arm length is settled. Here's new subject for you to discuss/debate/argure/bicker/whatever.
How about Dogbone/CVD angle from the outdrive to the wheel? I had a discussion with a team drive a couple years ago about it, but it was regarding 2wd offroad buggies. What is the verdict for touring cars? I found some pictures posted from different manufactures is looks like the stack up like this:

TC4 - rear swept forward, front straight
HPI Pro 4 - Rear forward, front back
Corally RDX - Kinda hard to tell, but both look straight in the picutes.
Xray T1 - Rear straight or swept back slightly and front back.

Again, this is looking at pictures. Hard to tell or even know if the camera angleWhat's the JRXS going to be and why? Will the shorter length have more or any effect?
For offroad buggies, the explanation I remember was with the dogbones swept foward, it has tendency to drive the tires or suspension into the ground more...more bite.

Idealy you want them as straight as possible, but then with the modern CVD joints, they are very efficient, so some deflection wont hurt I would guess.

So to those of you that have actually seen the car in person (XXXS Bill, Badboy ...others), are the pictures we've seen of the car you've seen on the track in person?
