RE: LHS told me not to break in my new s-600 motor
yup, i learned that emery wont work, so i used a file. i have a new problem, the spur.pinion make a terrible loud noise when the motor runs, and the pinion popped off once or twice. im thinking that the flat spot i made is way too small. and is it okay if only a part of the pinion is thouching the spur, because the shaft on the s-600 is way shrter than the titans
