Has anyone experienced similar jitter problems w/ their gimbal? See video; http://youtu.be/OLqr9lBABsU

I can't believe, straight from 3DR, I'd have to update firmware and tweak settings already.

Try connecting the gimbal tilt input directly to a spare channel on the receiver, NOT via the pixhawk.

I had this on my setup with an APM, and this resolved it.

Hi, I have had the same issue on my pixhawk, the result was a very noisy AUX output on the device, actually all AUX were noisy. I had no chance to fix it.If you fly a quad or hexa try to use RC 8 instead of AUX output,it may work.cheers

  That's not good. How did you determine that your AUX outs were too noisy? I'm using the new Iris+ quad.

    Well, I have tried all the ports with same results. I tried 2 things.On my gimbal (Basecam) you can see the PWM signal coming in and it jumped back and forwarth from 1080 to 1800.Then i used a simple servo tester, powered by the pixhawk (no external power) to pitch the gimbal and it was super smooth. My conclusion was that my AUX channels were unusable, noisy whatsoever..I presume you have disconnected the red lead from your servo connector going to the gimbal?
