Hot bodies 1/8 diffs
 

I bought flm hybrid bulks and almost have all the parts.I just need 1 more hbsc 8028 43t bevel gear and I can put them together. Does anyone know where I can find one? It seems that no has it in stock. If someone has one for sale I would buy it.
thanks,
Mike.

Damn, the entire internet is out of stock it seems. However:

and:

http://cgi.ebay.com/101036-HPI-43T-S...item27bb16cb6b

says its for the hpi trophy 3.5- it looks identical though so I'd guess its the same as the lightning buggy diff part... possibly.

One last option:

Those will be a direct fit for the FLM hybrid bulks, or just rob the ring gear and maybe the pinion too if the teeth dont quite match up perfectly with the HB gears- they should though really. Only $5 more than the HB ring gear on it's own + you get nearly a whole spare diff...

Thanks for taking the time to respond. I found a place here in the states called Discount RC. It shows that they are in stock. Does anyone have experience with them?

I just got notice of a refund from Discount RC. I found another place. suicideneil have you heard of, or had any experience with this store http://rc4speed.com/index.php?route=...roduct_id=129?
Thanks,
Mike.

Never heard of them, but if it's a European website thats probably why ( I mainly come across English, American or Chinese sites )- they take paypal and creditcard so you should be perfectly safe if they dont deliver the goods. :)

I'm putting together one of my hybrid bulks, and I am trying to get the right number of shims. Is it normal to hear any noise from the gears? or should it be completely silent? I am using gorilla snawt on the ring and pinion. I tried it with 2 shims and had some noise. I tried it with 3 shims with more noise. No shims about the same amount of noise. 1 shim seems to be the best, but i can't get it completely silent.

It's not noise you should be looking for really, its much more about feel & smoothness.
Ideally the pinion gear shouldnt be able to move in or out more than a fraction- it shouldnt bind however as you rotate it / the ring gear once assembled. Likewise, the ring gear / output shafts shouldnt be able to move in or out ( side to side ) more than a fraction.

Every diff is different due to maching tolerances but a few 0.2mm shims hear and there should do the trick; so long as the diff roates smoothly and doesnt bind or have excessive play, you'll be fine :)

I have little to no play at all in the output shaft so I think I'm O.K.
Thanks again,
Mike.

Are you using the hybrids on FLM's extended chasis? If so, how well does your front drive shaft connect to the break?

I will be using my hybrids on FLM's extended chassis, but I don't have all my parts. I am awaiting the arivial of my ring gear from some where out of Europe. The main part that I am waiting for is the universal CD/engine mount. I recieved word that Mike is tweaking the mount and they should be ready soon. As soon as I get those parts I can complete my build. So for now I can't answer your question, but I hope I will be able soon. I will post pics of the build process here when I can.

The new CD/motor mount is now up for sale. I have one on the way. I hoping that the ring gear will come in the next few days. It is marked as shipped but it is coming from
Malta of all places so I don't know how long it will take to ship.

Do you guys have any idea what size shims I should use to stop the little bit of side to side movement of the diffs?

They are 8x10x0.2mm items usually:

So the same shims that I used for the pinion gear.

what are the part numbers for the spider 1/8 diffs (ring, pinion, etc....)? If I break the HB's then I will go to the spiders.
