Revo tranny center-diff opinions?
 

Anybody use the Traxxas center differential (#5414) in a Revo tranny, under brushless power, and how’s it working out? I like the traction gaining benefit of unloading power to the rear if the front wheels come off the ground; just like a traditional buggy. Downside is this piece is prone to significant forces and likely to munch.

Anybody use with success?

Actually what you described for unloading is a little in reverse.

With the current MT setup of a tranny center you have no unloading of power front to back - front and back wheels are always getting the same power with a locked center driveline.

With a center diff - if the front wheels come off the ground then the motor power will push to the unloaded front wheels and you'll get less power to the rear wheels - the thicker the diff fluid you put in the center diff will reduce the unloading of power to the front wheels and give the rear wheels more power.

I've read in other threads that the Traxxas center diff is pretty weak, only has two gears in it so you have to use much thicker oil than you normally would, can't stand up to real BL power, and really isn't worth the money.

Personally I like the locked center in the MT - just makes it more fun for bashing around and wheelie action. :wink:

I have tried the Traxxas CD w/Kyosho 500k fluid in a converted BL Revo and not much of a difference from not using it

damn 500k is like just pouring a bunch of epoxy in there :lol:

yeah..its very thick ...the only think thicker is diff lock

mine with 120,000w is holding up just fine to the Nue 1515 2.5d

I tried the Traxxas CD in my converted 3.3 revo. Diff lock almost stopped the front wheels from constant spinning (faster then the rears) but at that point there was no real advantage to to using it anymore. I believe that aside from the minimal number of spider gears used that the long travel suspension on the revo helps work against the CD.

If your just trying to keep your front end on the ground I've found all of the following to be more effective and less annoying then the traxxas center diff.

1) extended rear A-arms (these make a huge difference)
2) move your batterie/s forward to better balance weight distribution. (this can help steering also)
3) properly adjust your slipper (it's amazing how very small adjustments can effect the slipper)
4) teach you throttle finger some self control.
5) if you like the way 2wd trucks brake in the dirt then get a quickturn front driveshaft. (many people swear by them but I could not get used to it)

So is the Platinum edition a waste of time with the Center diff option? I am think the E Revo, btu then again, the Plat has the center diff.

IMO if the Platinum has the same CD has the 3.3 than yes

does anyone know if the traxxas CD will fit into the erevo tranny?.....

my guess is no since it is a completely different design

anybody gunna make a center diff for the e-revo?

See this thread. Linc is.
