<div>Is is a digital or analog servo???</div><div>
</div>Ok, just to make sure what you said. Even with the pull-pull in place but there is no tension on the servo you get servo chatter?? If this is the case then it sounds like you might have some metal to metal contact that could be causing RF interference that is causing it. Check to make sure you don't have any metal to metal contact in your pull-pull setup. <div>
</div><div>You might want to also try a different servo and see if it works with a different servo. If it does, then you have a bad servo.</div>
