"clicking" servos

[RCNub]

Hello all, as the title says, i have a question about servos that "click" i am unsure how to accurately describe the experience but when i turn on the receiver and the transmitter, there is a clicking sound in the servo like it is trying to move. is this normal in new and old servos? and are there any recommendations as to where to find vintage parts?

Thanks in advance

I have had it happen in servos that had stripped gears.. Do they work properly?

yep some of them still function very well except for the clicky sound.

There's always a 'twitch' when you turn the system on. The servos are centering themselves according to the signal.

really? they still make the sound even after i take off the horns

Doesn't matter. They always get that first twitch. Put a round horn on them, put slight pressure on it while moving the Tx control to both ends and see if you feel a skip. If not, your servos are fine.
