I tried the stock setup for the first time in the garage yesterday evening (just finished building the beast) and even with very careful brake linkage setup, ie should roll free at neutral, use smallest possible servo arm to limit throw, de-sensitize steering with minimum dual rate etc it's still a very twitchy turner... looking forward to the results with filled diff! Will keep you posted, Ciao Paul

Also do you notice the oil warming/thinning up after running a few minutes? As for brake pad material, what are you trying to accomplish? Do you want more grip/friction or less? Looking at the different things people have tried I am not sure what is trying to be done? I know more modulation is what is essentially wanted but are you trying to do this with more or less grip?

I changed the one in mine last week, that 100'000 had gone thin as 80wt silicone shock oil after a few packs. What we are trying to achieve here with different pads is a more progressive feel... not more bite (there's plenty) or less bite (which would be counterproductive given the grease grades we run in the diffs) but something a less off/on in terms of braking action.

I have a couple different compounds I can try. I know the grease will wear out over time. I was wondering does the grease warm up/thin out after running a few batteries? As some one mentioned either here or another forum, a easy way to get the grease out of the tube is to warm it up first. The same thing can happen inside the diff. As the diffs works the grease warms up thinning out the grease. So when you first start driving the diff is nice and locked up, after running a little while things thin out and the advantages begin to disappear. Edited by Cross, Dec 1 2008, 05:09 PM.

My friend, if you know that grease wears out (badly) with the tearing action of the gears and thins out with heat (a bit - remember we're talking silicon grease here) then why ask??? in terms of thinning out "after a few batteries", given that a 3200 lipo lasts 20mns with a 9T delta brushless, and that typical running temperatures for this toy are sub-zero, I usually only run one batt at a time befor I feel the urge to go back inside... But I would think that it doesnt take "a few batteries" for that grease to heat up - I would think that after 30s of turning action it should be pretty dang warm inside, but then again I never felt the need to dissassemble the diffs in the snow right in the middle of a pack.

Worthy of the Trax! Posts: 54 Group: Noobs Member #1,584 Joined: November 22, 2008	ok i seem to think that i have the solution to everyones problem u wanna know ok here it is when u remove the diff to change it the first time drill a med size hole in the side were there is space to do so make sure when you drill the hole u have a fine threaded screw to screw in it before filling it with silicone this way after running it for a while if you think the diff silicone needs to be replaced just flip the beast belly up take out ur screw and empty the silicone when finished put new stuff in and then screw the screw bak in i have this set up for my nitro mayhem st it seems to work good but the silicone needs to be warm so change it immedietly after a run or u will be waiting a long long time.

Paul Yes I know grease warms up and thins out. That is not my question. The original question is after the grease warms up in the diff do the advantages disappear? If so using a heavier oil could be better.
