Very slow steering and throttle servos

[NORRYS]

Good afternoon, I apologize if my English is incorrect as I am using the translator.
I'm having problems with the servos of my hsp 94122.
They are very slow and I opened them thinking that there was no grease or it was dry, there was not much grease but that was not the problem.
Does anyone know another way to try the revive before I think about buying new?
Thank you very much.

Get a voltmeter and check the voltage coming out of your ESC canle going to the receiver. It should read 6V

Similar to what WickedFog said, check the voltage delivered to the servos when they're operating / moving. If this is a nitro car and power is supplied by a weak battery, the voltage could be dropping once the servos are under load and draw current.

Test your battery voltage, it should be at least 8.3 volts when fully charged. If the servo then indeed still doesn't turn and if you're not competitively racing, I'd get whatever cheap replacement there is.

You should power the servos directly with a 2S lipo battery. To reduce brown out of the servo. 3 servos draws a few amps.

That's poor advice if their RTR has 6v servos, which is likely. It's also only two servos, not three.
