I have tried every possible placement of parts
running old style ball and plates lasted 8 runs before failure, much longer than original thrust bearing.
Have even used Hot Bodies diff bolt and nut/wing unit, but still it gives in.
What puzzles me is that in goes suddenly, and at any power setting.
I am running with the HPI Firebolt motor, this is less punchy than a 17.5 and not quite as fast.
Diff is fine until you want it that little bit tighter then it fails, yet there is no sign of threads stripping or slipping.
Just so annoyed at this diff, rest of car is great.
just wondering if universals and alloy diff cups will cure it?
