RE: Savage Flux Diff Problems
about the HPI grease they don't come with that stock, its a black greese, i can't see the green stuff being very good in a diff or a whole tube doing the job either, its very sticky but it doesn't seem to like to goop and fill in holes and i can see it getting flug off the gears and sticking to the sides of the diff case as opposed to onto the moving gears where it needs to be and in any high powered RC you're diff is gunna get a ton of work this would cause lots of heat in there and then poof goes your gears, i'd also check your diff bearings excess heat could cause issues with those and they could be adding to the problem
i'd in the future use black grease or some diffs spefic silocone grease
