Would it be possible to mount the shocks on the front of the rear tower on an S2 to match the b4 geometry? Just an idea.

Well, if you don't run it, please do bring it with you still. ;)

It already is!


BTW: Is Danny seducing me? :blush:

He's a student, if he gets out of control just put him on a train - he'll be missing for days! :lol:

:lol::lol:

Ha bloody ha :o

just read on another forum about this type of suspension being nothing new (Elvo never claimed to have invented this thing). But I was surprised to learn that it even allready had been used on a RC-car before.

The Losi Jrx2 (1988) (with thx to Asso-man)

The manual is on here somewhere..... under 'downloads' or 'reviews' IIRC.

And the Tamiya Egress

how does it stop the wheel base shortening as the wheel travels through the suspension arc? i thought that is why i though double wish bone are more commonly used in racing to stop this happening. I know multi link is used on most modern cars due to it compact construction layout and good handling properties.

You Don't.

If you take a look at the cars used on the Paris/Dakar rally you will see that the use a 5 link system too.

If you design the drag links so that they slope up towards the front of the car at static suspension height - It will lengthen the wheelbase and add stability when the car lands.

You can also use a 5 link setup to add toe-in under squat for more stability during accelleration.

OOOO i want that jrx.

A:wub:wub:woot::thumbsup:

not good for on road if the yaw rate exceeds 5 degs of more in a corner as this could make the loaded side wheelbase in a corner shorter than the unloaded side in a corner. That said pug use a trailing are setup that works really well on the old pugs.

aaaaand... so what?

Besides, it depends on roll angle not yaw rate (which would be in deg/sec); and it also very much depends on the length of the arms and their angle at normal ride height.

Who cares, on road sucks :thumbsup: ;)

Good job Elvo :D

And their angle at normal ride height is ... up towards the front of the car. So loaded side wheelbase would be longer, not shorter.

(And yes, on-road is for wimps)

Looks very good Elvo! Props! :thumbsup:

How's the wear/slop coming? Is there much? I would think finding some nice heim-type joints would help.

You know, an X - 6 isn't much wider than a B4...

Slop is ... ... not too bad. There is some; slightly more than on a freshly built B4 suspension. But it feels as if it's spread out over 3 dimensions, rather than being mainly in the dimension where it affects camber but not toe-in. But then again, I didn't use new ball studs in 2 places. It's still fine after a few rough test sessions, which I think is also due to the fact that the forces are more evenly spread over all the different links.

Yeah, only 2/10 are heim-type joints. More would be better.

Chassis width is no problem, but having the shocks behind the axles is.... ... a bit.

Elvo,

What rear hubs are you using? Any chance we can see some detailed up close pics?

Custom made ones. They took many evenings/nights to design, and 2 days to machine.

I love it!

That is ace :)
