I started this thread to discuss the FLM sealed differential and stop cluttering up wmckay96's thread - sorry wmckay!!

As some of you may know, I have an FLM sealed diff on order from rc-monster, and kwitty already has one and posted some sweet pics of it on a different post. (This question could be posed to Traxxas diff's that have been sealed with the gasket mod seen on this site)

So my main question is this: how much oil should I put in the diff to make it work as it should, which is allow slipping on corners and hooking up better coming out of the corner, and on straights.

If I completely fill it with 20,000 wt oil, will that slip more than if I 1/3 fill it with 30,000 oil?

Any opinions/answers??
