What tires would you guys recommend on this car for a clay track? Was looking at schumacher tires and they look interesting but no one i know has any experience with them.

Schumacher have no clay tyres. I mostly use Pro-Line Holeshots/Wide Ribs on clay, but AKA, JConcepts and Sweep also make great tyres. Check out what the other drivers at your track put on their rides. ;)

If it helps, I believe the base setup is for clay and yokomo use dboots tyres

Is there a good bass set up for indoor carpet/ astro hi grip ? Building mine up tonight

Check mine from barham on 17 Feb I think it is on the mb yoko Facebook page.
That's full astro and was very good. I found the front had a little too much bite in slower twisty sections but was awesome on faster and sweeper type corners.

Ok will youse that as my bass setting then do you think my be lousing a wosher of the inside front ball stud might of helped ?

If you have problems with the parts e-mail [email protected]

That would increase the steeeing further

Schumacher doesn't have clay tires? Why not?

dBoots have some interesting tires but they dont' have anything under clay. But I'm guessing multibyte or nanobytes might be a good choice?

Schumacher are a British company and make tyres for the British/European market. They make tyres to run on astro and grass. There is not much clay racing over here.

JConcepts, Proline etc do not make tyres for astro so it is just catering to your audience.

any good carpet setups out there

Ahhhh.... Makes sense.

Hi, I just bought one of these and can not wait to build it. I haven't found a great deal of information or support for this buggy. Looks like only a small group of people are running it.

Do you have any tips to help me with the assembly or durability? Any help is appreciated.:D

As Yokomo was neglected in Europe and US the last few years it is no wonder that the cars are a relatively rare sight. I've run the original B-Max2 last season and found it to be the most durable and easy to drive car I ever had in twenty years of RC - I am getting old! :p.
With the recent release of the MR version, the car will become even more popular among racers and lazy guys (optional gear diff... ;) ). It will be interesting to see what the Yokomo guys have up their sleeves for the worlds this year.

The Bmax2 MR is such a versatile car. I've tried mid motor with saddle, will also fit shorty side way, and now I converted to rear motor, and it fits a full stick even with a full sized servo. Feels really good now on outdoor clay :)

Narrow suspension mounts
 

Can someone tell me what do the narrow suspension mounts do? The manual doesn't say anything. Sorry if its a dumb question, newbie here. :D

Thanks!

Narrower width up front will help if your buggy is too loose. But its not the first thing you'd want to do.

Give you a smaller front track width making the car more nimble and responsive on the front end.

I am about to try the narrow front end for the first time at the NRW-Offroad-Cup race in Dortmund on 11 April. Car turns on a dime in my living room. :thumbsup:

Thanks for the replies guys... however as I understand it, both answers seem to be opposite of each other?

"help if your buggy is too loose" which means the narrow mounts should reduce steering response?

"making the car more nimble and responsive on the front end" meaning it should increase steering response?

I have a question for those who have build the car in Rear Motor or anyone who wants to answer.
Speedo on the shelf above the battery or on the side? I mounted it on the side but it's a really tight fit (i have the HW V3 which is a rather small speedo) exposing the speedo on the side.
Judging by the space on the shelf it will be a hard job getting the wirring done.

So, what's your opinion and/or suggestion? (Photos are more than welcome :woot:)

If you have to choose a good configuration for rear motor, it is that one :

Speedo/Shorty battery/Reicever/Servo on line...( I haven't got photos of mine...winter period...Mid motor rules :) )

Rear motor is the king on slippery tracks...with the shorty battery centered.
It depend on which battery you are using...but the Bmax2 works well "light" with shorty battery.

Surface
 

Hi Steve this set up you've used what surface was it on polished floor?carpet

Seem be be a fair amount of drivers running them at batley. Just build as per kit instructions and run it, get the ae fron axles.

Would the wheel attachments from a durango 210 fronts/rears work?

front - yes, straight fit.

Rears - no. After you've put the TD / Tresrey 14mm hex onto the driveshaft you've a) not got enough thread coming through the wheel to get a nut on, and b) you've got a big gap between the hex and the hub - the drive shaft therefore floats.

Wonder if a TD driveshaft would work?

not running that anymore mate

what springs are a good starting point for carpet

Run it kit first

Your rear end will be more stable compared to the front end after narrowing front.

What shock oil and pistons are peeps using. I have number 2 piston 35w oil and yokomo blue spring but it feels far to soft

john just use the std set up as Steve has said....

you havent even run the car yet

start with the kit setup its a fair allround starting point thats why yoko put it to the kit................

Rear Motor Setup advice for newbie
 

So I've built the kit up and had a stellar time. Everything drops in nicely with no hand fitting required. :thumbsup:

This is my first offroad car. My experience is only limited to mod 1/10 sedan so I'm planning to run 17.5 non-timing offroad in rear motor configuration.

My questions:

Seeing how this car is marketed primarily in MR configuration, how does the base setup fare when running in rear motor config?
For instance, I've looked at the Yatabe setup for clay and although it is in MR config, the shock oil is significantly lower viscosity (22.5wt vs stock 400cst).

What kind of FDR should I be looking at for 17.5 non-timing? (Motor: Reedy Sonic)

Background:
I'm going to be running the car in southern California mainly at 2 tracks:

1) WCRC(Site of 2013 Reedy Race of Champions)
-indoor
-hard packed clay
-medium to high traction
2)IERC
-indoor
-medium packed clay known to clog tires
-low to medium traction

Per recommendations from fellow racers, I've mounted the following tires that will work at both tracks:
-Rear Proline Suburb MC
-AKA Red insert
-Front Proline Scrubs MC
-AKA Red insert

Any setup and driving tips no matter how seemingly small or insignificant are more than welcome and appreciated! Please share your knowledge here in or PM. I am eager to learn from all of you.

thanks:)

As your in California these two threads may be of help to you.

Thanks! I have looked at those threads too!

IIRC I used 72/28 as a starting point for my 17.5 motor. Cannot comment on California tracks, but on clay I mostly use red springs in the front, blues in the rear. Stock oil is quite ok, give it a try!

I too vouch for the red spring in front. The stock front springs are too soft.
I have 60wt Losi oil in front with the 6 holes pistons and felt good. tried 450cst and didn't like it. Rear is 350cst oil

It really depends on track. Oil and springs that work on one track won't elsewhere so don't get too hung up on what others are running. Its a new car and people have different styles. The best example of this is the setups of the worlds top boys. Try one and you might hate it.

The best thing you can do is go to track with a range of oils and springs and just try different things

Thank you. I did order a set of red fronts yesterday as well as another kit for my friend. We also got your recommended bmax4 wheel spacer and B4 rear hex.

Which piston? The black or white? Taper side up or down? 1.0mm vs 1.1mm. I have only one pair of the black pistons, last one they had. How did they affect the front end?

Plan to do just that but I would like the best starting point and go from there so I can save setup time and concentrate on driving. I want to make sure the car is not totally undrivable straight out of the box. We have two kits now and we're going to test back to back different things. We are excited!
