While there is very occasional chatter in the rudder/elevator/aileron servos, the chatter in the pan and tilt servos is constant and sufficient to be a nuisance in the video image.
Is this an Er9x issue or is something else triggering the noise such as the BEC powering the receiver?
What servos and video freq are you using? I had servo chatter issues with cheap (HXT-9G) servos and 900MHz VTX. I replaced them with higher quality servos (Spektrum/HS-55 type) and the chatter disappeared.
