I have a redcat terremoto v2. When I turn it on the steering wheels instantly go all the way to the left. After they are stuck in that position they don't move when I try to steer them. First I replaced the steering servo and it did the same thing. It went to the left then didn't respond. So then I checked to make sure it wasn't the receiver by switching the throttle and steering wire. The throttle worked perfect being switched. So it's not the receiver. So my only guess is that's it's the controller.
