Servo Jitter during movement

Hi. Does anyone with a JR 11X or XG11 have a problem with servos stuttering jittering during movement?
I'm using XQ 4020 digitals with my XG11. Doesn't matter which receiver I use. Even used a FrSky X8R. I still get the jitter during movement. The Servos work fine when used with a different radio. It's just the JR that is having the problem.

Edit: Note that the servos do not jitter while at rest. Just during movement.

I have both Tx's. None of my servos show a jitter when slowly moving the Tx sticks, except for my BB H50B servo. I fly a mixture of Savox and JR servos.

I think your issue may lie in the XQ servos...

Jittering at center, tends to be 2 different things..... Too tight of a dead band, it actually fights itself finding center, or wore out upper case (where the pins sit) or servo gears.

As bunky said... I am also flying an 11x use mostly JR and now Pro-modeler servos and none of them have a hint of jitter unless it's my fingers. I think like he said it may be your servo. Either a dead band issue or gear lash issue.

Do not how it can be the servo because he said that the servo works on another radio just fine. When you used the other radio was it with another radio and reciever or did you plug the the servo in another plane. Thr one thing in the old system plug it into another channel and try it.

My thought is that the other radio was not 2048 resolution... Maybe the 11x resolution is too fine for that particular servo

I'm a bit confused. You say the problem is only with a JR transmitter but the receiver you listed is for use with a Taranis isn't it ? Are you using a Frsky transmit module in the XG11 ? I've never owned an XG11 so I'm not even sure it accepts a module. Just trying to understand EXACTLY what you're doing...

I also use an 11x an have never had that problem. How much jittering are we talking about. The reason I ask was I was thinking if it's a transmitter issue if you could see it on the monitor screen on the 11x.

Have you tried the 11x on any other airplanes or any other servos?
