Ultimate FLM Hybrid bulks ( Emaxx )

Hurrah, I can retire from giving instructions & parts lists for building Hybrid bulks at last :party: :yipi:

And very well priced too, only $90 which is about half the price of UE Ultralites ( 6 spider diffs with a plastic cup is plenty strong enough but most people, just a few guys around here who are nuts enough to require 8 spider diffs :lol: )....

Yeah, was about to say that. They should offer an 8 spider version too. :)

FLM's own modified pinion gear?

I don't think the pinion is something they modified or make themselves, there are one or two Ofna models which have a pinion gear like that ( reduced in size from 8mm down to 5mm where it exits the diff case ). I've never been sure if those gears would work in the Hybrid bulks as some are apparently slightly smaller than others, but it seems like they do = all good news. :yes:

Reduced to 5mm? Aren't they reduced to 6mm?

The ultimate Hybrids are the same as the standard hybrids but include diffs and the needed shim to make the diffs fit - the diffs are smaller than the earlier ofna/Hot Bodies diffs the Hybrids were originally intended for. The diff pinion is 8mm at the bearing and turned down to 5mm at the drive cup - similar to Mugen, AE, Losi, etc. :)

Okay. So I guess the 5mm fits the Traxxas 5151R center driveshafts then?

The set includes a drive cup for using a dogbone. Traxxas center shafts are 6mm.

Isn't the "normal" FLM drive cups 6mm? They made a new one for this application? Why not use their normal 6mm ones?

FastLane "normally" makes many different drive cups, shafts, etc. so the 5mm is a "normal" FLM part.

I first saw the title I was thinking they put a 4mm pins for the a arms.
Yeah I saw these.
I like that they even come with the stock sliders axle too.

What diff will be included? If they are smaller that the ofna/HB, should they be weaker? Or they are better?

Do they do one for the rear as well?

Cheers gumleguf. Are these diffs going to be able to handle brushless power?

Absolutely, yes. They are a big improvement over the stock diffs. I prefer to use the 8 spider diffs with aluminum case myself. Have six of these diffs and one center diff.

I know the stocks aren't up to much cop but I really can't afford 8 or 6 spiders. I really want the Hybrid cases though so this looks like a good option :mdr:

The FLM hybrids with diffs are about as good as it gets.

Yeah I agree but you have to pay through the nose to get them! :lol:

What if you just need the diffs themselves?Will they be offered to be sold separately?

The diffs ( internals ) on their own are no good to you, they only work in the FLM Hybrid bulks, or the UE Ultralite diff cases- they are a different size & construction compared to stock diffs. You can already buy those 1/8 diffs on their own regardless- just hit up ebay for 'ofna differentials' & have fun....

You will not find a better price or option for 1/8 scale diffs, only thing that comes close for less money are the LST2 diffs, which have to be modified in order to work correctly ( mounting spacers & swap the output shafts etc ):

Best option
 

This is surely the best option to the stock setup, and for the price there is no way to beat this deal. Way to go RCM & FLM for stepping up your game or this class of R/C vehicle. Using the 8 spyder diffs are surely the strongest setup you can buy, but the 6 spyder should be just fine. $90 for the entire setup is just awsome.

So do they come with shims if not what size do you need and what brand of diff is that in case i need to repair one? And i was wondering what gear ratio will i need i have a stock emaxx with MM

They are ofna buggy diffs, not sure of the exact model but you can find them by doing a visual comparison to ones for sale one ebay:

Looks like the ones ( look at the pinion gear & how it is reduced to 5mm at the end, most others are 8mm all the way along ).

If shims are needed, then they will be 8x10x0.2mm shims, easy to find:

What do you mean by stock emaxx & MM- do you mean the newer 3908 & the MMM ( MambaMonster ( Max ) = MMM, MambaMax = MM; don't mix them up... ) system? In that case, you ony need to gear up 1-2 teeth on the pinion gear to get the same overall ratio as you would have with the stock diffs. I recommend something around 22-24/65 on 4s lipo for ~40mph, but let your motor, esc & battery temps guide you if you want to go faster ( a hot motor and cool esc means you need to gear up, viceversa means gear down ). More lovely info about gearing and emaxx related stuff in my sig :intello:

diffs are a godsend for peopel looking to beef up. I wish i would have been a few weeks later ida saved hundreds not buying UE 8 spider diffs.

Ive got mine all shimmed out thanks to neil they feel good now the problem i have is the cvd"s keep popping out with the suspension dropped all the way down do i use the extended erevo cups or the hpi cups i looked at there dimensions and the stocks are 17mm long and the extended ones are 19mm long will 2mm make that much difference?

Just give them a try. If they are a little long then you can hit them with bench grinder. In my build there were a lot of little things that I had to grind or file to get them to fit.

turn the pillow balls in

Yeah that was the first thing i tried i found that the cups that they send you with the kit work great but they only send you four two for the transmission and two for the rear or front diffs leaves me two short

That would be 4x drive cups for the diffs only- normally you would continue to use your stock centre driveshafts so no need for cups on the tranny. If you buy a set of dogbones or have an aftermarket chassis which includes dogbones, then you'd buy or have 2 more drive cups for use there too. :yes:

Ill try that but i dont believe you can use the cvd style driveshafts with this chassis but i might be wrong this is my first build so bear with me lol !

:yipi:Ok i finally figured it out thanks for all your help i used the chrome drive cups from my traxxas cvd driveshafts and installed them on the transmission and used the axles that came with the chassis so i was able to use the four i got in the kit for the diffs

They are sold by a company called CASTER RACING.:neutral:
