My servo failed after the first few hours of use and after installing the new one, it turns further to the left then it does to the right. I did the calibration to reach the endpoints of steering, and it does go perfectly straight with my hand off the wheel. I lined up the steering arms so that they look perfectly straight. I saw a video that said I should turn on the car with the new server plugged in so I can reach the neutral point before I put on the steering arm. Please help.
