I have had my geared diff strip internals after about 5 week's. Running 7k oil on carpet. Has anyone else had these fail? Is anyone shinning the gears as I was advised it wasn't required. Any help appreciated.

What ? The metal ones.....

(I assume you know the plastic gears are for stock/spec only)

I did not experience any problems with the plastic internals, but several others did. When the metal internals became available I installed them to play safe.

Is it just me or does that car feature a front hex wheel conversion by Yokomo?

MattK · #**745** 09-03-2014

It is the metal diff gears I am using.

Not forgetting the motor mount

Special LCG version!

No release date yet for the hex conversion, probably as soon as my AE parts arrive.

Is the yokomo bmax2 worlds car any good on low to medium grip surfaces like outdoor sandy or wet astro turf? Thanks

mes · #**752** 11-03-2014

If set up properly, it will be more than capable. With a more flexible chassis, (in this case plastic or skyaflake's cf chassis) any car will be more forgiving to a less than perfect set-up und as such easier to drive on lower grip tracks.

Cougar99 · #**753** 11-03-2014

Thanks, I think I am going to probably go for the factory team yokomo bmax2 then to suit the tracks I race on then if I get one.

mes · #**754** 11-03-2014

Considering the price of the worlds chassis alone I'd probably get the worlds car and go for an additional (cheaper) more flexible chassis. You can also tune chassis flex with the cf and plastic battery mounts.

Cougar99 · #**755** 11-03-2014

Ok I'll bear that in mind thanks

Has anyone found an aluminum replacement for those hub shims? I mean the transparent and black ones? These transparent especially are brittle like sh$t.
I've seen a photo of Naotos car with some blue anodized ones, but cannot find them...

I had to use one of these (cannot remember which thickness) and a kit black shim, as two kit ones were too tight.

New Yokomo Europe FR brass suspension mount available:

skyaflake · #**759** 18-03-2014

Great for low traction situations. Yokomo Europe's quality is great, as usual.

As I'm mostly driving on medium to high traction tracks there's no need for me to actually use it, but I could use it as a tuning option.

I'm currently (slowly) rebuilding the B-Max2 with a hard gearbox (i've ran the stock gearbox since it came out, never had problems) and with a harder ackermann plate (made out of carbon) which i'm going to test. I had to shim the steering posts to reduce the slop. Feels smooth again.

My shocks held up great and they will only get some fresh o-rings and oil. I'm using CSI pistons at the moment, but will switch to 1.7/1.6*2 soon. Just to feel the difference as some team-drivers prefer them over the 4 hole design.

The only thing i'm currently thinking about is to switch to a 6.5 motor for outdoor. I prefer a little bit of overpower, so probably for me it's fine. The only downside is the battery drain. So I will need to test if I can drive about 9-10 minutes (just to be sure) with a shorty in the car. Let's hope so.

I'll pick one of these up this week as MB have them due in.

I just did mine. Replaced topshaft and bearings as well as going back to new plastic idlers. I found that the topshaft was wearing away the first idler, which was leaving aluminium filings inside the gearbox. The first ali idler was worn with angled teeth, as if contact with the topshaft was not square. Hopefully the new bearings and hard case will sort this out? The second ali idler, the one that drives the diff was not worn at all. I caught it all before a failure anyway.
I wonder if its best to run steel topshaft, plastic idler, ali idler then to diff?

Have you got a photo of this please?

You should easily get that run time. I've had 20mins out of mine with shorty and 7.5 outside.
