Jammin X1 - so close yet so far
#2117
5-7-3 is a good starting point for most American tracks.
I do exactly what macnkitty does. I think it's always better to have a little more than too little. If you overfill it, just loosen the screws slightly and push the gear side down-the excess oil will drain out.

Hi guys,
Take a look at my article about my debut on 1/8 buggy racing at the Mexican Nationals this last weekend :

Diff Oils

I will do that next time i rebuild my diffs for sure.
Does the diff oil expand when it's hot?

Well, it was my first race ever in MT and Buggy class and i can tell you that just a few drivers made some mistake cuting curves or something like that ... and when that few did it, the race director sent them to stop&go once, stop&go + 10 seconds on the second time and disqualyfication on third one ... but as i say, that was not a problem during the race ... i think that on the only section where pilots were cuting something (including me) was a little curve after a double and heading to the uphill and the cut was of 30 cm max, and for the finals they put a very big red cone on that curve
Thanks for your words ...

Pato, Watching those videos you're driving skills were very impressive for you first race with an 8th scale buggy. With a little more practice you will be destroying everybody. I look forward to seeing more videos of you races.
What motor do you run? can you post a link so I can see it? It looks very strong and for half the price I might be willing to try one.

SavageSYNTH, Diff fluid doesn't expand? I was always told when it heats up it does. When you build your diffs and fill them up all the way do they leak? Does it change the preformace when you fill them to just over the crosspins instead of all the way? What diff fluid do you use?

Hey Dan-O, it sez in Pato's vid that he's using the STS D21T. I was actually going to buy one of these prior to the start of the race season before I made my fateful Collari mistake. However, I was going to buy the original version (D21B). You can get them either at www.projectzen.net or www.racernine.com. I just checked the prices and noticed the D21B has dropped to 130$ and the D21T has dropped to 175$! Sweet deals considering all the praise the STS engines get in the nitro engine forum.

DRKWNG, I've never experienced diff oil expansion, expecially with heavier viscosities. If anything, the oil may move around if the diff is not completely full. I've never had a leaky differential, except for the stock Mugen diff-that was fixed with good ol' Carolinas RC o-rings. The only thing I noticed when not filling the diff all the way up is it felt as if the car was "diffing out" more....This was on a very hot day though. I use Xray diff fluids. IMO, filling the diff all the way up keeps diff performance consistent, and it's better to have a bit leak out from an overfilled diff then to have a halfway full diff. Just my .02.......
