I'm guessing the interest in gear diffs is to play w/ oils to slow the diff action without the slip associated w/ balls. I'm wondering what that would feel like on an electric car. I know what it feels like on my nitro car but electric doesn't have the weight nitro does, any one driven an electric w/ fluid filled diff?

All in all the diffs are my biggest pain point right now . I've taken to cleaning and rebuilding them once a week now because my performance is SOOOO much better w/ a clean smooth diff than w/ a gritty one. I have a mcmaster thrust and a set of ceramic balls so i don't replace any parts just sand my rings flat on 600 or 400 grit sand paper clean thoroughly with denatured alcohol and rebuild w/ green slime on the balls and black grease on the thrust. I've also made it a habit to check the bearing in the diff once a week too. For whatever reason the losi ones seem to die a quick death.

A though just struck me ... anyone have an old losi hydradrive laying around they wish to donate? I wonder if we could retrofit that. If memory serves isn't rather small?
