Futaba 9252's chattering
My set up:

DX7
CC 110HV
3-9252's
1-9254
Duralite Regulator 5.1v
Flight Power 2100 RX style pack

I cannot seem to get the chatter to go away from my system. I've managed to get all sub trims to 0-4 points. The Regulator is atleast 6 inches from the RX. There is no stress that I can tell on the servos,,,at all.

Seems like I can goto 50% pitch(dead center at 90 degrees) and the chatter quiets a bit. As soon as I pull full NEG pitch, the buzzin/chatter is back.

Is there a possibility I need a ferrite ring,,,would this make any difference? Or could there be interfierence with the way I mounted the servos to the CF chassis?

Thanks

Still sounds like binding in the linkages. Does it chatter with the links disconnected?

More likely they are just digital servos chattering, its what they do.

If there's even a slight load on them they fight to center.

Make sure there's no binding and the links arent excessively tight

Digital Servos...
I have to agree with BarracudaHockey.... as long as you know that all the linkage is free then it is most likely just the digitals hunting for center... just the weight of the blades on the head can cause this... just double check each link, and also as suggested, try poppin all the links off and then add them back one at a time starting at the servo!!!!

Good Luck, Stan

And BTW, the HV series controller are optically isolated and can't feed RFI back into your receiver.

If we ever leave the in-laws, I can get home and unhook the links just to be sure it is not binding and such. These are my first Ditigal servos as well, so I may be being overly paronoid too.

Thanks for all the help.

It pays to be cautious. Digitals normally talk just a little as they constantly lock center, but if you preload them with a bind, current draw goes through he roof, and it's very hard on the motor and amplifier.

Welcome to the world of digital servos. Their guts work differently than analog servos and that difference introduces the buzz when they are not moving.

As others noted, make sure the links are free to move and that you are not coming up against a mechanical stop before the servos are done moving.

If that is OK, live with it, it is not a problem.

I popped the links off the servos, and the servos were much more quite, while letting off a buzzin sound here and there. From the sounds of it I must have some binding in there, and that needs to be addressed. It must be very minimal though, as I think I have the head/links set up pretty true. If I have my links where I want them currently, what is this going to do to my swash plate being completly square now? Sounds like I need to re-vamp the whole head.

Thanks for the help.

Brian, connect the top linkage and then place the bottom linkage up to the ball. Eyeball closely. You are probally a half turn off and that will stop most of the buzzing. Or vice a versa.
