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.

stu

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.

Where are all the setups for the MR2??
There aren't that many on petitrc

Maybe the kit set-up is just too good. ;)
Ran the car in rear configuration today in Troisdorf (sandy astro) with worn Multibytes in the rear and high-profile Staggers up front, 1 degree aluminum hubs. The only thing I changed was taking the shims from the rear camber link and adding them to the front. Although my Max was slightly slower (non-blinki SXX and Vampire Bloodline 17.5) than the LRP Challenge guys with their blinki 13.5 turns X12 motors, I ended up second overall. Not too bad for running the first time on our new track layout without any previous practice! :thumbsup:

So where are everyones setups?

I tried the car indoors yesterday on carpet with slicks (thats what we are allowed here) and liked it. All I changed was a harder rear spring from avid white to yellow but I am still looking for a little more steering.

Flat landings/over jump from maybe 1m height (only one of those jumps) will bottom but not bounce that much

Thoughts are welcome

Did anybody try the 2hole black 1.6mm pistons?

Thanks

That is what i have and i ve been told its good but i am one hand down so i cant drive good. but i need a good mid motor indoor carpet set up. any one got one!

Try my one or really anyone of the ones for smooth astro on the petit site or in this thread.
I haven't changed a lot from the outdoor settings which is a suprise for me. Maybe Im just getting better :woot:

I worked a little more on my setup (3 posts up) and have 15% dragbrake and 2x10gm (20gm total)up front instead of 10 total.

Best change today was I tried a shorty foward in the battery hole and thought it worked really well. This will be my go to setup for now.

Still looking for a little more on power steering... suggestions?

I also tried the narrow bulkhead thinking that I might gain a heap more steering but wasn't any difference so went back to the standard.

I think that tires (slicks) are playing a big part with on power steering, but Im happy with how it is working out with it only being the second time on carpet with the yok

My car gained a lot of steering when I went softer in shock oil in the front. It was just too much for my local track. :thumbsup:

My BMAX2 MR Batley Outdoor track setup:
http://courgette.jml.net/~neal/RC/Bm...ey_Outdoor.pdf

Also used in Cullingworth and York Indoor tracks, with different tires.

I used this setup on a tight indoor setup: http://teamyokomo.nl/setups/BMAX2MR/...IO_BASE_SV.pdf

Still needs work, but for me it's a good starting setup for a tight indoor track.

After a few changes here is my new setup
I am using TD springs that sit "ok" under the collars. Ill be looking at making them a little larger or getting another brand.

I also gave the tires a really good clean (slicks with addative) and this helped

Here is my current setup, also used it on indoor carpet. Changed the tires and front springs, and it was good to go.

What front springs did you change to for the carpet? :confused:

Since it was indoor carpet I went to Losi Green. If its real astro you may need to go to bleu

My latest setup its working really well lots of steering and with ARB

Remember:
Its with slicks and addative
My driving style
Small track

Here are my latest grass setups:
