I broke my stock servo saver so I replace the one I had with a spare. the spare was so tight that it chewd through 3 servos on one race day. ( 2 futaba BLS 352's, one ACE 1015) I read the manual and it says for a losi 8t "tighten all the way and back off two turns" after I did that its been fine. Still kinda tight but my servos are still alive!!
