You're right, the plastic diffs will take some decent abuse. It just depends on your weight, tires and surface you run on, idler condition (very important), motor and gearing, etc. I obviously exceeded that limit, and needed a change. I am surprised to hear you have no problems with a Feigao on 4s! You must treat her well :027:
