I got a typhon 3S V3 when it came out. Had about 25 runs with the car and no issues at all with the servo. Then one day, I jump and hit a curb and the stock servo was glitching when I turnt it. I replaced the servo with a 20 kg power HD servo. I know the stock servo uses a 23tooth gear, and the new servo I got uses a 25 tooth gear, I also could not use the stock servo saver so i just settled for a traxxas plastic white servo saver. With all of this, the steering does not seem To go straight even after I trim it out. My trim is more to the right on the transmitter. Also, when I physically turn the wheels, it is very stiff to turn the wheels- when I had the car stock, the wheels cold turn freely when I turned them with my hands. So is the lack of it not steering freely when I turn it with my hands and it not be centered on my transmitter due to the servo saver ? Because the servo works perfect when I remove it?
