Stephen:

Hi,

I have a few of the KO 2413 servos and really like them. the low profile is nice and I felt it worked better than the 9550 I had.
as for the feeling you posted about. are you trying to turn it by hand with a servo saver?? it could be the servo saver working and then catching making the 2413 feel like you posted. I hardly ever move any of my servos unles it's under power from a Rx pack. I feel it's not all that good for them.

Thanks

Try loosening the servo case, but not too much. If the case is over-tightened, the gears will bind.

It should turn freely. If not, either the case or the one plastic gear is damaged.

unscrew the 4 screws half a turn.... mine gets much better and faster after this. you should be able to see the rubber seals ease a little. Check for the case to be even (same space between parts) all round.

cheers,

what do you mean? They are already there.... if you took them out, that means that you're squeezing the gears....

there must be 2 square rubber gaskets (or seals) one for each joint on the case, plus 4 o'rings, one in each screw... what I'm saying is to unscrew only half a turn each screw, assuring that all the pieces are parallel, otherwise you're loading on side of the gears more than the other, thus bending the stuff inside... this way you make the gears run more freely...

I bought mine 20 days ago in Japan
it had the case screws already loose (case almost open!), but was already notchy moving by hand, I managed to close the screws and tried it - not a lot, just 4 packs, it seems to work fine ('til now) even if is still rough and almost impossible to move by hand.
