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.
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.
