I have syksurfer v3 with avionic rcb6i transmitter.
When i move elevator on channel 2 it doesn't work just fluctuate and due to this elevator only vibrat.
I done all stick calibration.

If all things on the Tx is normal, Check connecting another servo on the channel and try if it's working. Jitter may be caused by loose connections or low voltage. Make sure you have had a secure connection.

Is ur tx new or its gone though its life bcz after using tx for long time then stick sensors which is I think hall effect sensor stop working it hapoened to me

Well that looks more like a weak connection to the RX.
Check for a break/ loose joint in the white/yellow wire of the servo.
If there's none, Please try to use another servo on the same channel.
Also try to use the service which is acting up on other channels. If it still acts up, the servo must have been stripped.

I check everything. Other servo also give same problem at that channel. 
I thing there is problem with transmitter joysticks. May be it damage.

i check all connection and also replace servo too t But still same problem... Now i thing i teardown the transmitter and then check a variable resister used at joystick for channel 2.

Wait.
Have you tried using the same servo on a different channel?
Maybe the servo is stripped.

1. Put a new servo on this channel and see
2. Put this servo on another channel and see

Will identify whether servo or radio is faulty...

I did suggest him that.
He did not respond.

I check everything

Yes i also observed that there is a problem in radio
But unable to solve

Please give some solution

I realise you checked everything.
For our benefit can you please clarify these two queries?
1. Did this servo work properly on another channel?
2. Did another servo work properly on this channel?

Sorry for repeating, but could not make out from your posts...

Problem solve after long time
In rcb i6
Solution-
Calibration of sticks 😊

Also avionic rcb i6 transmitter has problem with mode 1 and mode2 slot botton at back of transmitter
