My Race Revo

this truck is blowing my mind. I'm just getting into the whole eRevo thing, and all I can say is wow!

Finally found the diff oil setup that suits my driving perfect, and the suspension is also dialed now, for rough tracks

So how exactly do you go about deciding that you need a different diff oil? Just curious. I've heard others talk about it. In bigger vehicles, you choose your oils mostly based on the amibient temps you run in, and how severe duty you need (ie., I tow with my truck, so I run a severe duty oil).

How does this relate to an extremely small vehicle, that runs for 15 minutes at a time?

Thank you Squirrel! Here's a recent pic, just for you :)


JThiessen, finding the perfect diff oils is always a trade off. In RC it pretty much all depends on the amount of grip your area/track offers. Basically, I want them as stiff as possible, without spinning out under hard acceleration, but not to light as it would unwind on the wheel with less traction. See? Hard to explain for me.
For example in the center, too stiff would even give you wheelies, and too soft would only result in balooning front wheels with no acceleration.
Front-to-rear ratio depends on driving style: DO you want the most traction in turns, or do you like to drift through them, or do you only want to swing its rear, etc...
Hope this helps. Playing with 8th scale buggies gives you a good feel for it.
