Also, try it on a different channel...jitter could come from a pot in your transmitter. If your transmitter has a monitor function, take a look. Also make sure you don't have expo in the wrong direction. Also search around youtube....some peole have reported that a different servo can induce noise on other servos, leading the other good servos to jitter. For example, see this demo. It might help you trouble shoot your setup.
Thanks for the info. I'm running the recommended Airboss ESC w/o a BEC. The servo extensions are the same gage as the servo wire and all my expo is fine. I wish I would have read your response before I switched out the servo to try some of your trouble shooting ideas. I did show the guys at my LHS what it was doing and they said it was the servo. These guys are pretty knowledgeable.

If it is the pot on my transmitter what's the fix for this?

I didn't think about making a video of it. I need to be better about thinking about video. Just like I wish I would have had video of me climbing 30+ feet up into a tree to recover my plane when I was first learning to fly.
