First of all you need to make sure your servo is centered properly. When you center your steering servo you need to make sure that your steering trim is at nuetrul (spelling?
). Check your car to make sure there's no debris that's blocking it, in the tc3 debris can easily get in the sliding thingy (I forgot what it was called
). I would also check your radio to make sure your steering endpoints are set correctly, if your radio has this adjustment. What kind of radio do you use? I hope this helps!
