I just did this on my tc3, first center your servo and have neutral radio settings. Then put the horn on as straight as possible and tighten it on. then set your link for steering throw to the rack. The wheels should be straight after this step. Then try it out and adjust for torque steer oin the trims. U should also tweak your car for even weight transfer from side to side and front to back. Make sure camber and toe settings are even on both sides.
