I have two of them and have used both in these isolation test. Three air planes are having the same issue none have a badger switch. I think Judge may have the answer, I may need to be de-gaussed.

That's only because of your magnetic personality.

OK that was funny.

Dumb question. Are the servos mounted to tight? The eyelets are on the correct bottom side?

Nate that was a good question. Eyelets are in correct and I do not over tighten any more. I have also done the test with a servo sitting on foam while holding by hand and still have the issue. I am still working with JR support.

With a XG-8+6 and a NIB 11BPX receiver on loan from JR tech support California. A special thank you to Jun for the help. I tested three air frames 12 JR S-8911 servos, seven of which are NIB and I still have the problem. The problem is the servo or my thumb every thing else eliminated.
Test on 10-29-2020 with JR XG-8+6 and NIB 11BPX receiver JR S-8911 Core Less NIB (1 min 42 sec)

I have shipped the test equipment back along with nine servos. I now just sit back and wait.

I've got a wild thought. What about at the field away from your phone/other electronics. Really has me wondering what is the constant here?
Reading back I saw that you were having the same issue with other servos? So if It's not the servos, JR receivers, JR radios, power, extensions, what else is left?
Does it happen with another brand? Ask a guy with a Futaba radio to bring a spare Rx/Tx Fasstest and see if it goes away. Or Spek/Jeti/ doesn't matter. Eliminate JR with a new protocol and just cross that off the list for troubleshooting.
I'd like to buy you a beer once you figure this one out.

I have arranged for a Futaba radio for testing. I have sent several servos in for testing. This issue seemed to just start recently.

Festivus, with no wooden extension on the servo arm, kindly repeat the video test of post #58 . . . just the servo arm, please. Oscillation like before, or not?

I did attempt to film without the dowel extension, it still did the jitters but it did not transfer to film. The dowel only made it obvious. If I can get the time I will try again.

Today I acquired more test equipment. Futaba T6J and R2006GS. Doing all the same test I have done with the JR trans and receivers I still have the jitters. I have eliminated every possible component down to the servo's and myself. I currently have nine JR S-8911 servo's at JR tech center being tested. I guess now I call my doctor to run test on me to see if I am magnetic or if my nervous system is emitting strong RFI

My wife's hands trembled and she couldn't tell it, nor anyone else. Yearly check up showed thyroid problems caused the trembling,that the doctor seen.
