I own a HPI R40 and have 4 geared differentials on the front and back.

In theory, what would be a good default setup for the oils?

I currently have 5,000K in the front and 50,000k in the back. I am rather unsure how the different oil weights work together and how it ties into understeer (push) and oversteer (loose).

Can anyone please explain to me how it works?

heavier diff oil = more friction on diff gears = diff closer to being a spool (solid axle)

not sure how it affects understeer or oversteer though, but i have a feeling that the heavier the fluid, the less power you lose during cornering but the more understeer you gain (just a guess)

A good starting point is 10,000 in the rear.and 30,000 in front.the loser the track the lighter oil you should use.(not writen in stone)many variables,setup makes a difference.but this is a good starting point.
