From what I've read, there backwards compatible with the Revo diffs, but not the Maxx diffs. Not sure though.

No, Zinno (MOD there...) said they are backwards compatible with the maxx also

But I thought Neil said that the bearing sizes are different..... IDK

The entire new E-Maxx diff, housing included, can be put into an Maxx truck.

However, only the diff internals can be put into a Revo diff. (by that they probably mean the spyder gears, pins, and that new little mid brace thingy).

does that mean I can use the combo bulks????

Or just alu bulks?

It looks like the diff housing is different (internally to allow the use of the Revo style stuff), so you probably have to use some bulk that allows the use of a stock maxx style diff housing.

so just FLM bulks??? I just want alu bulks so I font break them every time I drive it..... So it they don't work thats fine, saves money also.

So either way its fine

To be honest the only part of stock bulks I'd be worried about is the part where it connects to the shock tower, and even so its not much of a problem from what I see.

The only reason I got aluminum bulks is that the hinge pins would bend in a certain area ONLY because the bulks would allow it. With aluminum bulks, that area of the hinge pins NEVER bent. I ripped an RPM arm right out and the hinge pin was still straight as an arrow (though another part of it bent, which annoyed me).

However, my plan is to just run JDCarbon hinge pins...to run these, you just need to tap a set screw into the bulks (super easy if you run stock bulks, still not really that hard with aluminum bulks).

However, since these are CF, they will flex a little without breaking, helping to absorb impact. However, most importantly, they can't bend, so really you either break them or you don't. If you just keep a second set of them with you (they only cost like 16 for the whole set) then you will never have to worry...this is my plan if I get the new Maxx at least...

With reference to diffs:
There is a heck of a lot of confusion over on the Traxxas forum, however, I have carefully studied the part numbers and exploded views so that I can provide a definative answer. The new emaxx diffs use different sized bearings on either side of the 'pumpkin', so they will not work with the older maxx style casings. The internals however will be a direct fit & upgrade to existing revo diffs. The entire new emaxx diff is a direct fit for the old emaxx and t-maxx bulks. Therefore, you cannot use the new emaxx diff internals with the flm combo bulks- only the entire diff with normal plastic/alloy bulks.

I find it amazing how even the traxxas employee over there wasnt aware of this at first, and still one or two kids over there want to argue the toss when the exploded views simply dont lie...

Which bulks did you use? I want FLM, but I havent looked at the traxxas ones, but I think FLM's are cheaper, and have a warranty...

So overall, the alu bulks do a few things a?



Yeah, its really starting to piss me off!:diablo:

I ask a question, and get 100 different answers, and all but very few are newbs, and the only person I have actually gotten help by, was you Neil... So thanks there man

So, thats what I needed to hear, so sounds just like I need to add some FLM's to the list then huh?

Any better ones? For the 80 dollar range?

In that price range you are looking at maybe the Garc bulks, or NewEra have some nice simple 6061 bulks too- they look fine, just no fancy maching done to reduce weight etc. To be honest I would say the FLM stuff is best overall for price, design, weight and the warrenty factor.

I honestly dont care about a lil extra weight...... But FLM stuff is nice

Have any links to them? How much are they? And are they just as strong as the FLM's?

NewEra

GARC

Both are 6061 t6, though GARC also do 7075 t6 which is more expensive, but much stronger.

Do you think the new ERA's are good?

For the price, I would DEF take them! Are they as good as FLM's?

That I cant answer, but there is one guy on the traxxas forum who has just bought some for use with his emaxx- he also bought the NewEra aluminum chassis (cant think who it is at the moment). NewEra stuff is generally really nice for the price though- I was very happy with the TXT-1 parts I bought back in the day, very high quality and precise. For what its worth, I think they look very robust, and are made of 6061 t-6 (same as the FLM stuff), so I guess its a case of personal taste; curvy FLM stuff vs aluminum version of stock but more solid....

I actually think I might put 300 into my revo, and do a revo conversion

Get a 3.3 chassis, new diffs (maybe hybrids?) and a few other parts, and do that
