run 7k or 10k all round for starters as you are on relatively high traction. get a feel for what the car is doing.
I currently run 7k front, 10k rear on indoor low traction and car is best its been.
I run the orings.

Thanks Neal:)

I race at both Kidderminster and Telford, i use 10k front and 7k rear as it gives i a good balance. Yes add the extra O rings.

Did you try that with the XB4 at all?

no not higher in the rear. wish I had now. it may have helped.

Another thing I've found with this car is the stiffer rear springs and kit 1.5mm anti roll bar really help with rear grip. I had gone lighter and lighter spring and no roll bar on the xray, and it was loose. found the same on this car. so went to heaviest spring and roll bar I had and rear is locked. nought heavier springs and rear improved. again I should have tried this on the xb4, but it was the opposite of what everyone and setup sheets/guides were telling me to do in low traction.

Really liking the look of this kit and im quite tempted to get one.

What extra spares do people recommend to carry in your pit box?

Anyone had trouble with the front axles on this car? Have had two totally destroy themselves so far.

Not yet. Still going strong. Both L&R got destroyed? That's pretty odd. :(

Yes one on each side. Right hand side has cracked and fallen apart, left hand side has cracked.

Where are they cracking?

I've had one fail in the first two weeks of running the car. The CVD cup shattered in light indoor use. I'll dig out the pieces and take a photo, if i haven't binned it?

Been fine since I replaced it with parts from MB Models. Not sure if they were bmax 2 or 3 parts? part no. BM-010FAC. I've also kept a rear one spare just in case: BM-010RAC

That's unusual. That's a B-max4 II part also. Fingers crossed I haven't had any bother.

Yet.......

Same part, near where the pin goes. I will try and upload a picture tonight.

I've heard a few reports of these shattering on the III, wondering if a batch have been hardened to much. I had one on the II get a hairline crack a long time ago, which I only noticed when the car was stripped down.

when i had my kit i had another set in the box saying upgrades on the pack??

i will take a photo after for you as i fitted the ones that come in the kit, if they snap i will change them but so far so good,


i did have a small problem on sunday, on the rear right hand side the wheel come off in 3 heats, later found the rear drive pin snapped so solid ones are now in place and fingers crossed it should be good to go again :thumbsup::thumbsup:


well happy with my kit :thumbsup:

Do I need the aluminium rear hubs?

I heared that team drivers use them because they proveide more steering.

Is this true?

You don't need them. But in theory they should flex less in comparison with the plastic hubs. If you have the money for it, you can buy them. You won't be that much faster. Maybe more consistent.. if you feel the difference at all. I don't think so.

B-Max4 III 4MM front towers are released, by Yokomo :thumbsup:

Arrowmax(yep the tool people)

Have a range of carbon bits for the Bmax 4III
including a chassis

http://www.arrowmax-rc.com/index.php...&cPath=101_202

That chassis seems very cheap. Bits look nice tho.

Exactly what i thought...

The chassis looks the business but at that price there must be a catch. I want one. :woot:

are the front arms interchangeable left to right?

Yes they are

thanks.
there looks to be 2x part-numbers for the lower front arms.

Is BM-008FH the "hard" version of BM-008F?
Any benefit to this- stronger?

That's exactly what they are. I have a set but never used them. I'd imagine they'd take away the flex slightly.

Are there any after market spurs that fit the bmax? Rw? Kimbrough?

My car squeals like a banshee. Even more under braking. I've already put some tape between the bearing and centre spur holder. Suspect it could be due to the spur ..

A couple of basic things to check, I dont want to tell someone how to suck eggs but check the following:

Does the spur look ok?
Are you using an old pinion?
Is the slipper set correctly? Mine sometimes churps on acceleration and braking especially on high grip but doesn't continually slip.

Hi mate, thanks for the tip.
pinion = brand new.
spur = not so new. i thought 1 or 2 teeth looked chipped (eye-sight not the best).
i adjusted the slipper setting at the track but it didn't help. It was a loud plastic-ky squeal. If anything, it reminded me of the horrible sound when your motor moves and start stripping the spur. anyway, i noticed that the rotation was very notchy & loud when moving the car on the floor (with electrics switched off).

swopped over to another spur (a spare spur was more suited for stock 4wd rather than the 6.5T i had in the car now) and presto, no more squeals.

ordering a new spur soon ..

Shorty lipo conversion I did on my mates car, I made all the carbon bits and redrilled the standard chassis
http://img.photobucket.com/albums/v6...psd82018f0.jpg

Yeah I done that too. Not tried it yet tho.

What speedo you got there Disco?

Does one of the new holes hit the cut-out for the spur?
if so, did you use spacer to fill the gap?

It's a Yokomo Pro3+

Yes one hole is half over the spur recess, I didn't bother with a spacer as there is still enough of the chassis to land on and it's all held together nicely anyway.

I just realised i opened this thread, and just now i bought my B-Max 4III.
That happens when you have limited budget... never mind.

I inform everyone that on newer batches the new shock bottom cap is included. Smooth shocks out of the box!

Build went awesome. Having built and owned the b-max4 II, a lot of things were the same, and those different were easier (begone *&@#*@& upperdeck).

Can't wait to run her!

Hello

I made the hole in the frame no problem for me ;)

Nico from france lol .

has anyone used the Gokuraku wing? Do you know what's the width?
It's described as "narrow wing" but I cannot find any specs for it ..

http://www.teamyokomo.eu/yokomo-euro...-Off-Road-Wing

Those wings come with the car.

The new wings are not available yet.
