X1CRe setup

[rcsammy]

I just got a HN/Jammin X1CR which has been converted to electric

Can anyone help me with a basic diff oil setup? I have only ever run electric stadiums and short course before so have no idea what diff oils to go for, at the moment its still got the old setup from being nitro which is making it diff out to the front all the time.

Its running a castle neu 2200 on 4S-6S, run on dirt/grass/tarmac

Just after a general setup really, i can alter it later on, i just dont know where to start

Or even better if there is any setup sheets around for an elecric CR so i can get the suspension settings too

Thanks

there are set up sheets on ofnas website and from a personal perspective and previous owner with that same motor on 4s i would suggest 6-8k 8 would be a lil on the heavy side. i was running 5k and thought it needed a little more thickness

[rcsammy]

what do you mean 6-8k in all the diffs?

Differential fluid listings are always done Front, Center, Rear by any normal person. I've seen people talk about them backwards but thats really odd.

So if someone lists 15/30/5 then its 15k front, 30k center, 5k rear.

I don't know if I'd go that thin on the center diff. Might cause massive unloading of the front wheels under full power acceleration. I know my truggy even with 100k will still turn front tires into pizza cutters 4S. On 4S its plenty controllable at speed but 6S can get crazy stupid. I'm looking into purchasing a Nexx8, and I'll probably end up with 30k or 50k in the center.

So many recommend differently.
I think it is track and driver that determines the final oil.
Test out a couple different kinds and see which you like.

Thats true because the viscosity in those three diffs can drastically affect how the car/truck handles on and off power. I've just found that with high power engines I needed it to keep the front end from washing out and transmit more power to the rear.

In my MBX5T running a 1520 on 5S my oils are 20-100-10. Now, I only bash so that is why my center is so high....not to mention the 1520 is a beast on 5s

I have noticed and read that most like lighter in rear so doesn't have the push in corners.
I guess when accelarate then the front lightens and the rear wants to push evenly.
I seen someone say they ran like 10k front 30k center and 2k rear before.
That wouldn't seem to bad either.
Also depends on if you run 6 or 8 spider diffs too.

6 or 8 spider diffs shouldn't affect power transmission, only the strength of the differential. Its still considered an Open Differential, ie.. power is transmitted to the output with the least resistance (aka inside wheel).

Thicker fluid in the rear reduces the amount of power sent to the inside wheel, more evenly distributing the torque. On loose surfaces this makes life easier. On higher traction surfaces its power lost.
