Coming from electric cars I'm new to nitro buggy/truggy. Set up wise I know a bunch from my electric on road days but this diff oil set up is still foreign to me. Could somebody kind and experienced enough give me a crash course on the effects of diff oils in front/mid/rear diffs. Thanks. Currently running 7/10/5 on my 8T but I want more on power steering, what should I do with my diff set up?

try a 10/15/ 3 setup gives alot of on power steering

I pass this around as much as possable. [link=http://www.teamxray.com/teamxray/products/proddwnld.php?prod_id=2588&kategoria=0&catName=]truggy and buggy set ups explained[/link], it applies to any truggy or buggy, not just the xray. Save it for further help, I do. Its one of the best how to help pages you can find. Just click the link HUDY Off-road & Truggy Set-up Book (pdf) - English Size: 3750 (kb) its like the 3rd or 4th one down.

7/10/3, Gives me good on power steering,

You may just need to adjust your suspension and tire setup, Id try that before messing with your diffs,

Check out this link. It may help you out.
