Servo always sounds as though under load
 

the ko 2343 in my xx4 always sounds as though its under load even though it isnt. when i do apply left or right when it centres it does so with a judder...

ive dialed out servo trim and that takes out some of the load but still have judder... any ideas?

Try a power capacitor plugged in receiver/soldered to servo wires and/or look for any binding in steering (remove servo and see if steering moves freely)

good tip re the binding cheers... i wonder re the capacitor as the 2343 was not one of the models that came supplied with one originally - would a retrofit be a normal upgrade in these circumstances?

2343 is a digital servo. Digital servos often sound like they are loaded when at neutral - as in reality they are loaded. Digital servos are always looking for the exact position - but they basically don't ever get there - so they are always hunting either side of the desired position.

I wouldn't worry unless it is really straining, if it's humming, then i'd say it's normal. The judder likely suggests worn gears, as this is another example of it hunting for position.

super thanks for the above v helpful!
