LOL its not the servo or the darn radio, its the cheesy servo saver, you need to put a proline servo saver or even a ue servo saver on it, then you will have no more problems with the centering. ITs just that the whole maxx steering system is a bit sloppy and the servo savers that are made for it just suck. You dont have these kinda problems with 1/8 steering, and the proline and Ue kit replaces the whole stock steering system.
