The steering on newly bought CT5 RTR is problematic. I would appreciate some help to get it fixed. The problem is that the wheels do not return to centre once once you let go of the steering wheel. You have to turn the steering wheel slightly in the opposite direction to straighten the direction of the car. This extremely irritating especially on a track. I have tried a new servo saver but this has not cured the problem. What do I do? Should I get another higher torque servo?
