Official Erevo 1/8 scale center diff thread

[ZippyBasher]

Well to keep this thread up and alive... I just bought the items needed from AMAIN and I will try my hand at making one of these.

With threads rolling through about everyone trying to make a maxx cd, I thought this route was better as I can retain the Slipper assembly. With Mikes Maxx CD mount that is supposedly coming soon I would need to spend extra on a slipperential and I am short on $$.
I am going to be installing this into a 3905 maxx; (same tranny an Erevo) I dont think this will work with a 3906.

Anyhow I will keep this updated for anyone... And thanks everyone for putting all this together...

It would be nice to know if it can be done with the smart diff innards. If you try it, keep us informed of how it works. From what I know (and I don't know much) the smart diff uses the same diff case with the metal inserts and the same ring gear. I just don't know if the extra parts that go inside the smart diff would catch on the two screw heads for the posts that secure the output gear. If done well, the screw heads are well below the inside surface of the ring gear but I just don't know if that's enough for the smart diff mechanism to not catch or rub on them.

So we have one confirmation that the Losi Smart diff can be used for a CD on the E-Revo. That's cool. Now we need an update on the performance like sjcrss said. Get to work Semi

i love torsion diffs, i run them in everything


i would love to tell you all it rocks and you all can't live without it but i live in MN, there is afew feet of snow on the ground and it is below 0 outside even in the daytime (really its been nice this week, mid 20's) so i dont think i will have my revo out for afew months.

its been winter along time, i think i rember seeing the sun in june or was it july?

Ok so I received all my Parts to complete this diff.

I am going to use a Losi Heavy Duty Case, LST bevel Gears and an 8ight B-1.0 Spur I had laying around.

So my main question is when putting the holes in the Traxxas Output shafts Is the Correct measurement .190" from end of shaft to center of the hole being drilled?

Just a bit confused from Mistercrash saying .190" on an OFNA diff output. Yet I am using a LOSI diff. I want to be certain that this is correct for the LOSI diff as well.

THANK YOU GUYS!
