Putting a Annikos 25kg servo in my big rock. So when 1st servo was changed at LHS he put a savox servo on it. No servo saver. Diff LHS guy said it "kinda has 1 inside it." So now that servo is trashed. Should/supposed to/ have a servo saver? Why didnt they use my og saver? I mean is there a good reason? *NEWB HERE*
