Default servo movement with less resistence then the rest, whats up?

Hi, I have a couple of old hs 55 servos and some off brand ones on a rtf heli I bought I rotated the servo arms on all of them and some of the servos had more resistence then the other ones reguardless of brand. Is this a sign of wear or just natural I've never noticed it before? Any help is welcome.

Not sure why this would happen on say identical HS55's, but I can say that different model servos often feel very different. For instance, HS635's have a smooth low resistance feel compared to their less poewerful but also Karbonite geared HS435 siblings and JR 591's for that matter. Could it be something to do with the gear ratios?

Moving a servo by hand will prove nothing.
You might be able to screw up the gear train, if it is plastic, but that's about it.
