No, but I've never been hard on it either. Between a lack of interest in rc, and the stock friction shocks, I've not run it much. Just pavement runs enough to dial in the radio. I am curious though, might take it apart and see whats actually in there. The truck came with a diff part for drifting, it's a spool for the front, with the ring gear all made together in a solid piece of plastic. I was surprised at the diameter of the drivelines too, and the axles are CVD style rather than dogbones. I suspect the hub/control arm connection will be the weak point, completely different design than traxxas by the way.

Forgot to mention, the hardware was better than expected as well, all allen head, most counter sunk.
