And here is my setup http://teamyokomo.nl/setups/BMAX4III...enburg_MIO.pdf

Used in a tight indoor, medium traction track with some jumps.

Being new to Yoko, and new to 10th 4WD I thought I'd ask for thoughts and advice here on shock set up. It seems from what I can gather everyone tends to run with AE flat pistons, in 1.6/1.7mm x 2 hole variant.

It would be good to hear what people favour in piston and oil specification and where. I am currently building my kit and looking to run at on an outside Astro track. I am going to start with (as I have them) taper down AE 1.6mm x 2 in the front and 1.7mm x 2 for the rear and see how it goes.

Thanks Sylvain for posting your set up, I think I'll base oil weights around yours and tweak to suit the outside temp, once I've converted the weights for Losi that is..

To use the 2wd slim spikes on the front I'm guessing you have to cut the wheels? Or do you run them on full width 4wd wheels?

No, they fit on the regular Yokomo front wheels fine.

only stagger ribs or cut staggers need the rim cutting, but i didn't like those on the car.

Top stuff, I'll give some a try

They feel a lot better than the regular balloony 4wd front mini spikes, which I found to give more grip roll and the car just wants to tip over in the corner, like it rolls onto the round tyre profile. I think a lot of the effect of grip roll comes from tyre sidewall gripping the astro, not just the spikes.

Hi

just having a look over your setup.

You have put on the sheet that on the front you used BM-S1270 Yok orange

And on the rear you have used YAS-700 Yatabe orange

looking at the spring chart on petit rc the YAS-700 is a front spring.

Did you use a front spring on the rear? :eh?:

oops, I made a mistake...

Should be the YAS-1025 orange rear.

Kit Orange front spring BM-S1270
http://www.rccarshop.co.uk/index.php...ange-soft.html
I kept coming back to this after testing.

The Orange rear BM-S12100 is also good.

I'll amend my sheet, cheers.

Bmax4 set up advice
 
Hi guys, picked up a Bmax4 ||| with L/W shortie chassis, I'm looking for a good base set up to use on med/high grip carpet. I've ordered the YAS front & rear springs & hard roll bar kits, it's the rest I'm after. Do you all run kit roll centres & toe in etc?
Any advice would be great

Cheers

Here's the car so far. Really like it so far! 👍

High roll centre rear, low roll centre front. If its med grip, stick with the 3 degree rear toe, 2 degree anti squat however you can always go to 2.5 rear toe.

Yatabe Purple front, Yatabe orange rear. 550cst (roughly 45WT) front, 400cst (roughly 30WT) rear. 1.8 roll bar front and rear. 10k front and rear oil, however you could go 30k front and 20k rear as this is something the Yok drivers, mainly Lee, have been experimenting with lately and they like it.

Just PM if you want more info. :thumbsup:

Edit. I meant to add, we are using the 15 degree front caster blocks and the alloy rear.

Pedros20 01-01-2015 11:00 AM

Thanks for that buddy, much appreciated! I'll get the spanners out & it done! :thumbsup: can't wait to run it!

Does anyone have a setup for grass for the BMax 4?

I'm close to building my shorty version BMax and have built it as per the instructions with 35 front, 30 rear and Yoke orange all round, 10K front and rear diff.

Thank you. There are quite a few changes compared to the kit build!

What benefits are there of running the YZ2 rear arms?

They are shorter so it adds rear grip. The geometry is also changed slightly which helps balance.
