With my TC i came to the belief that when people first used a gear diff they used to soft an oil.
I was wondering if there was something wrong with my car ass I came out of corners, as it was sometimes a bit vicious. I think I have 2000cst in my gear diff at the moment.
I just seem incapable of getting the ball diff to work properly - when I have it set ass per the very good Losi diff set up guide on you tube, I can't get the slipper set so that the front wheels lift
that's why I am using the gear diff, but I would love to use the ball diff (always like them)
