I just received 5 8611a's from Horizon today. 4 out of 5 have some sort of clicking as I move the arm. 1 is completely smooth no clicking. Just curious, are the replacement servos you guys are receiving completely smooth? I would think in light of the situation that any new servos going out the door would be checked. Now I have to turn around and send 4 of them back that were just sent to me.
