New to 2WD - heavy diff fluid?

Hey everyone, I’m new to 2WD and will be starting an electric Vesla build shortly and was wondering if it’s advantageous to put 20million weight fluid in the diff instead of the manufacturer recommended 500k. I’m assuming heavier weight fluid will put power down to both wheels evenly, but am not sure it’s recommended because it’s 2WD only. I’m used to near locking the center diff on my Kraton with heavy diff fluid.

I plan on trying and adjusting if need be, but I’m always open to thoughts/opinions/advice.

TIA
 
Need to find a balance of traction for the rear and still letting the diff spin so it turns decently well. 20mill is a bit stiff imo fir a 2wd. I'd start down around 1mill, and even that I'd be inclined to see how the 500k does first and go up based on performance.
 
as sean said above fella, start at the 500k and see how it suits your driving etc,(y),
i've just put 500k in my baja diff and thats the first time in a lot of years i've put that heavy an oil in there,
 
I agree on the stock weight an tune from their. Run it, take notes, test and tune till it suit your terrain and driving style.

John Parks recommendations based on experience are always very good but his rigs are seriously overpowered (Not complaining 1 bit) and the powerplant has to be considered. A 8S or 12S motor will deliver power vastly different in a straight line, corner or bumpy terrain than say a 50cc or 71cc gas motor. Heck even a 50C discharge to a 100C battery is way way different.

That is what i like about RC anything. It is far cheaper to make it yours than in the real world.
 
So, If I have a ESP 34cc on my Vesla and it is hard to go in a straight line through low cut grass, I would assume that the 500k diff fluid needs to be increased to 1mil? I have the DDM Giant Knob tires and the grassy area was mostly dry but green, so there is lots of traction. Even if I start slow first, as soon as I lay down the throttle the rig gets really squirrelly to the point where its hard to get up to full speed. I'm still trying to understand.

Do you stil have the slipper? If so, Back it off an 1/8 of a turn and test till it slips where you need it to.
 
@Ferrebee88 its not so much a case of the rig itself, its a case of getting used to the characteristics of driving a powerful 2wd vehicle. Steering and suspension geometry plays a big role in the handling and stability when you whack the throttle in a powerful 2wd rig. I'd start with some toe in on the rear as that will help with higher speed stability as well as lowering the speed of your steering servo.

It is probably because I got used to driving the Baja. It is so much lighter and handles so well. I just have to play with it more. I'll try some toe-in as well.
