I have a HPI RS4 3 and I seem to be having troubles with the alignment of my wheels (front). No matter how much fine tuning I do it seems that the car will tend to veer slightly to the left or right. And when I accelerate hard it can sometimes take a drastic veer to either direction.

Has anyone ever had the same problem? Is the a quick fix? Or do I need maybe a new servo arm or something?

check to see if you have an play in you steering linkage. other then that check you shocks to make sure they are not leaking and you ride height is the same.
