Well, that is exactly what I have done. Only difference is that I'm using HPI silver (black colour) springs and Tamiya 400 shock oil (kit oil).

Sadly, on Petitrc, there are no "base" carpet setup for the 418 as there is for the 417v5, and the March Reinhard setup was the only modified setup on Petitrc.

I will give that a go and work from there.

Be wary, 400 tamiya 400 oil is likely far from equal to Muchmore 400

Yes, I suspected that. But I can see that other carpet setups are using Tamiya 400 oil in the shocks, so unless the kit oil is very different from normal Tamiya oils, I hope I'm good for a start.

Need help again.

Please look at this setup sheet:

http://petitrc.com/reglages/tamiya/s...ice2013110103/

In the bottom to the right it specifies for the front separate B suspension blocks (for the rear).

For the rear, the setup sheet specifies seperate XC suspension blocks (for the front).

Two questions:

I have separate suspension blocks with 1C - 1XC marked on them. Guess these goes to the rear. But does the 1XC side sit closest to the centerline or closest to the edge of the chassis?

The front specifies separate B blocks, but I only have blocks with 1B - 1XB marked on them. Does the setup sheet really mean 1B - 1XB blocks? And again, how are they mounted? 1XB side closest to the centerline or closest to the edge of the chassis?

XB (etc.) is a narrow mounting, B (etc.) is a wide mounting.

Sosige is correct. X is narrow. Non x is wide.

A/XA has the least difference between wide and narrow, F/XF has the most.

Having dual use split blocks just means less sets in your pit box and would be less expensive to fill your pit box with every conceivable option - but actually just as many parts....

Don't forget that when changing blocks, you are not only changing toe/sweep but also track width.

For example, for the rear using either X/F, XA/E (std) or XD/B would achieve 3deg of toe in. However, X/F is a very wide car, and XD/B would be very narrow.

To clarify on your questions;

You sit the setting you are aiming for to the inside. So if looking for XC with a pair of C/XC blocks, mount the XC marking to the inside (toward centreline as you say)

For the rear blocks - front = closer to middle of the car

Split blocks are always dual use, so yes, MR is using B/XB blocks, with the B marking to the inside/centre.

For the front blocks - rear = closer to the middle of the car

To explain what these mean in terms of "setting"

FRONT
-0.5deg of arm sweep (0.5deg "out")
Approx std width

REAR
3.0deg of rear toe (3.0deg "in")
2 steps narrower than std width

Some like sweep on carpet set-up's which usually has the front suspension block one less than the front suspension blocks (i.e 1C and then 1B)

Tanks a lot, it now makes sense.

I had installed the 1C-1XC blocks in MR's setup sheet with the C marking to the centre, which gave me approx. half degree of toe out on the rear wheels (in the Hudy set up system) which alarmed med that something was wrong. They are now installed with the XC markings to the centre and toe in in the rear is now correct.

When you copying Marc`s Setup Sheet with the rear Blocks with XC and C what you installed?

I have never seen splitted XC Blocks only this one 54065, single Block. XC and C was 3 but when you use C-XC and C it`s 0. Because C-XC is C

What is incorrect at that sheet?

Or I don`t know that the splitted XC Block exist

Split XC/C blocks DO exist - they are in the 418 kit for starters!

If you build the car with C - C , you get 0 degrees (like the front of the 418 in the kit).

If you build with XC - C you get three degrees (like in the Rheinard setup for the rear suspension).

Well, no errors in the setup sheet I guess, just my ignorance in play

The "Marc setup" specifies a split XC block for rear-front (see attached picture).

To copy this, I have used this block:

http://www.modellbau-seidel.de/index...iya&best=54174

I have installed them with the XC markings on the two blocks closest to the center of the chassis, as instructed.

With the long (1 piece) C block in the rear (as specified in the setup sheet) I think I remember it gave me a 3 degree toe in (in Hudy setup tool).

In fact, there are two versions of the split blocks, where the new ones have been lightened. But they can both be used and are interchangeable.

The "new" version of the 1XC block I have used are this one:

You own a 418 - what came with it?
