I was concerned about my stock diffs breaking like so many other peoples have been on Flux's so I called up HPI last week and asked what my options were and they offered to send me free upgraded replacements so I wouldn't have to worry about it. Simple as that!
Well I guess I will be calling, I just dominated my rear diff running 2 2 cells
If they broke, no reason they won't replace them for you.
Well I contacted them and they said to send them a pic of the broken diff, and they would only replace it not both, I thought you could not mix and match them? Shouldnt they replace both?
