I have a question for those HPI experts. To save me the time of taking two cars apart, are the differentials interchangeable between the HPI RS4 Pro and the HPI Sprint? I want to use the ball diffs in the Pro in my wife's Sprint for VTA and want to lock one of the gear diffs and get a one-way for the Sprint so my wife can use the Pro for drifting.
I doubt it as the Sprint was originally another company's car (Neo) before it were bought out by HPI. You never know your luck though - maybe Neo copied the HPI diff...
