Hi guys, I am upgrading my HS65 to MG because the carbonite gears stripped in a crash, I rebuilt it but I have this part left!!!!! (the picture is attached to this post) what is it???? where do I put it??

Something else, I tried to use it like that, and I put the battery ON just to try it, on the bench without motor, the servo moves fast but then when it arrives at the end (maybe 2mm before the end) it goes slowly.... what is wrong??? is the part that I have left affecting????

Thanks...

goes between the screw and servo arm as you screw it on the the output spline......

sort of like a locking washer...

but if you are using MG, I would use a very small drop of Loctite

it's what I did, a drop of locktite....

but what happens with my servo???? it doesn't work properly..... I see the other HS65 responds very fast and strong... the servo I rebuilt responds fast but before getting the end, it slowers, watching the swashplate, I can see that it's slower moving the swashplate in comparison with the other 2.... what did I do wrong???? I have built servos before, first time MG though....... (it was a carbonite HS65 that stripped and I bought the MG replacement) it should work fine, shouldn't it????

It sounds like the case of the servo is in a bind. The metal gears are quite sensitive to that. You need to make sure that the holes in the frame are opened up enough so that the servo case does not get twisted or bound up at all when you tighten up the screws that mount it to the frame.

Good luck!

I checked that man and it still does the same thing..... it responds slower than the other 2 []

Could it be lack of grease in the gears???? I don't have grease, that is why I didn't put on them

If you remove the servo horn and manually move it with your hand, do you feel any binding. I am thinking that the binding is not from the servo.

Well, "apparently" it's repaired..... what I did, was to streap it appart again and rebuild it since the very beginnin, this time it seems to be working properly, I'll try in on the air tomorrow... I would think it was the binding in the servo case as ct420 said.... thanks!
