I have a Savox 1258TG in mine. I used no spacers as this servo has a pretty deep offset. The line formed between the center of the rack ballstud and the center of the servo horn ballstud is perpendicular to the centerline of the chassis lengthwise when the servo is in the neutral position. This is how it should be regardless of what servo you use. Use the spacers to get there.
