One of my futaba s9252 servos having some issue. When I hold the stick at certain point (slightly above the mid stick), the servo jitters and jumps a few degrees. It does it constantly at the same spot.
It is not the servo gear. Not the radio either. I tried several radios and different Rxs. Nothing changed...

It feels it is the pot going bad. Do I have any chance to find a replacement pot for s9252?

These servos aren't cheap and still very popular. I don't want to say bye to it yet...

Any help!...

PS Called Futaba techincal support. They are not helpful other than telling me that it would cost me $40 to tell me what is wrong with the servo...

Sounds like a worn out pot for sure. Send it in for repair. It will come back good as new and it is cheaper than buying a new servo.

I see it rex but they asked $40 to tell me what's wrong with it. This is what they charge to diagnose not to fix.
I don't know how much the total bill will be. I am guessing around $50 maybe $60. If I am paying that much, I rather buy a new one...

Thanks I need 1 servo only. (Maybe 2 if I find a really good price).
I am looking into fixing this if possible first. It seems finding the pot for this servo won't be easy as not many people replied to it...

Futaba service will sell you parts. Ask for 9252 pots. About $3 each. It's a real job to replace but a good learning experience for you. If you trash the servo, buy one of his.

It was the first thing I asked the Futaba service guy "If they would sell me a s9252 servo Pot". The tech guy said they don't sell those kind of parts.
Have you (or someone you know) bought a pot from Futaba?
If so, I can call to bother them again. I wouldn't mind...

I buy parts all of the time. Just say, "I want to buy some Futaba parts". If you sound like you don't know what you are doing, they will say no parts.

Then I will try again. I wouldn't lose anything...

helixangle, JR is worldbrand and makes good quality stuff. But they are not superior to Futaba. Rather it is not the intent of this thread to see which brand is better. Both are the leading names. No one can answer which is better.

I will find a way to fix this servo

First off, it is $18.50 to check-out/test the first Futaba servo and $6.50 for any additional servos. There is a $9.99 charge for return shipping. I have sent in many damaged servos, they get repaired and returned with no or minimal charges other than the check-out and shipping costs. So, send both suspect servos in for repair. It may cost you only $35 to have both restored to good as new condition.

Why buy the pots and do it yourself? Is money that tight? If so, you are in the wrong hobby! Sorry for being so frank.

Send them all back at once. You can't fly with any missing.

I only have one s9252 that need to be repaired. And that is out of my chopper. It is my spare one. The ones on my chopper are working fine.

It is not only if the money is tight or not issue. I don't like to pay more than what it actually needs. And I enjoy reparing things. I am a handy guy when it comes to electronic and small repairs. I have all the required tools to do that kind of repair. If it can be fixed for under $10 (for example), why pay someone $30 to $40 to fix it?

Will call Futaba again Monday. They are closed now...

Had some JR 8231's that had been in a Freya for six years. Finally, one went intermittent, found that the wire harness connections to the PWB had frayed and broken. Tried to fix it myself, but the copper wire had oxidized enough over the years to be pretty much unusable.

Sent the three 8231's to Horizon. They replaced the pots, put on new cables, charged me $20 apiece for the work. Got three "new" servos for the price of one.

Maybe Hobby Services would be as kind to a Futaba owner and their servos.

wasn't trying to pit one against the other.

Just impressed with the fact JR is the only company offering a 3 year warranty.

don't really know what makes one servo better than the other, outside the obvious speed and torque specs.

Check out Tony Stillman at Radio South...

http://www.radiosouthrc.com/radio_repair.htm

Looks like to replace a servo pot will be about $20. I'd guess parts, shipping would be extra, but sure beats a $40 beat down just to tell you the pot is bad.

They would not sell a tail servo pot to me but told me the part number and go to the LHS to order that part. It was real cheap. You have to be careful on pulling out the parts. Also helps if you can desolder and solder.

Excatly!..

I called Futaba again but this time I didn't ask them to sell me a pot; I asked the part #. They told me the part # and I already ordered thru my LHS. It is just $3.75 a piece and I am not even paying for a shipping because LHS adds it to the main order...

Hopefully I will fix this servo for lot less than what I would pay for Futaba to do this for me...

Update
I finished the reapir on this servo. Part(pot) was only $3.75 but it was tricky to disassemble the servo. It is more complicated than just replacing the gears for sure. The motor and servo pot is soldered to the main board and the main board is attached to the middle servo case via the motor and the pot. There are two plastic clips holding the pot. This wasn't the problem as they can be undone with a flathead screw driver from the top openings. The problem was the motor. Futaba glued the motor into the middle case(if they had used a screw, it would have eliminated unsoldering the motor. So to remove the board and reach the pot, motor needs to be detached from the board so the board would come out. That means motor leads (including the tiny ground lead) need to be unsoldered.
Magnifying glass and fine tip soldering iron needed. I also recommend desoldering brait or bulb to remove the old solder. If you do not have good soldering skills and patience, forget about this job.
Anyways, the servo fixed for $3.75 but I put hours of labor into it))
For those who might need, the part number for s9252 pot is FUTHSP58185
