Euro's Setup
 

And anyone got the B-Max4 euro's Setup? I have a race in a very similar track here in Spain and that would be much appreciated...

Indoor set-ups
 

Hi,
Does anyone have any indoor set-ups for racing on quite grippy carpet, using big bores?

What springs?
What shock oil?
Extra weight added?
etc etc.

evertonal.. indoors i´ve come up with f35/r30wt oil. black pistons. green front springs, orange rear. middle on tower front and rear.

inner on front wishbone. outer on rear.

tight front diff.. 2mm schims on front camber links.. standard holes front and rear. and front wishbone mount is flipped upside down.

this is with slicks schumacher tires and additive. no swaybar.

kikefu, check out the setup section on petitrc.com

jörn neumanns two euro setups is there.

Thanks!!
 

Thanks a lot Otto! I didn't see the one at the bottom.

Sway bar on front end
 

Does anyone run a sway bar (aka anti roll bar) on the front end of their b-max. Looking at the pics of Tom Yardy's b-max at the Stotfold national, he is running a front sway bar. I have never tried this before, anyone else tried it, especially on astro? Did it help or hinder, in particular does it give or allow a faster turn in?

the whole point of having a roll bar is to reduce roll. Generally when your putting a sway bar, it will produce less grip, so putting it on the front 'should' reduce the bite on the front.

I tend to use roll bars at both ends of the car, normally 1.2 at each end. The main reason for this is that the Yoke is quite a heavy vehicle and as such, creates a lot of body roll which is often a positive handling characteristic, but if you are racing on a technical, high bite track that requires fast/smooth change of direction, I find the roll bars are crucial.

The front bar in particular makes the car much more responsive, but if you regularly race on expansive flowing tracks which don't offer particularly high bite, it will likely be more of a hinderance.

Does anyone have a good setup for clay/bumpy to the bx (not the bx-w)?

I find some at petit but they are old and I'd like a new one.

Please help.

Friendly.

Hello,

Can someone help me with these setting? as in what exactly they are.:confused:

The blocks have the hinge pin holes slightly offset and are design so one or both can be fitted upside down, to adjust anti squat angle.

On that setting both have the hinge pin holes in the lower position.

"to adjust anti squat angle" is there a number related to each? Take the TLR 22, it uses degrees, something i can get my head around. I'm just trying to understand so i can make an educated guess/adjustment.

dont forget

front block up and rear block up is the same anti squat as
front block down rear block down but the roll centre is different

stu

but what's the anti-squat?

it doesnt realy matter either

max anti squat middle anti squat or less anti squat unless you are comparing to another car its irelevent.

OK, so..
1. F-up, R-up is HRC?

2. F-down, R-down is LRC?

3. F-down, R-up is less anti-squat?

4. F-up, R-down is more anti-squat?

Ok now you have established high and low roll centre and more or less anti squat in TLR terminology what next?

Not sure if your asking for what antisquat is, or what the actual angle is on the bmax....so....

You can adjust the angle of the rear hinge pins for both anti squat and toe angles.

Anti squat is the vertical angle of the rear hinge pin (as opposed to toe in which is obviously the horizontal angle)...on any car it's typically set with the front of the hinge pin a little higher than the rear of the hinge pin...hence the angle number that the losi, and most cars describe it with.

As people have described already, if you lift/lower both the front and rear ends of the hinge pin with the blocks, you won't be changing the anti squat.

Simple description of the anti squat adjustment...more anti squat (lifting the front end of the hingepin, so increasing the angle) gives better lift of jumps and bumps, but reduces side bite, and vice versa.

They don't seem to tell you what the actual angle is on this car, so all you can do as go for more or less based on the settings available, and the setting you are currently using.

Thanks discostu and blue.

Wouldn't #3 also = RHC?
and #4 would be LHC?

Blue, i was looking for an actual angle.

i thought the only way to change the toe angle of the rear on a bmax4 was to buy different rear hubs?

i suppose you could measure it as long as you measure pin heights from the same datum point you could probably work out what the degree angle is.
