One of the reasons you aren't noticing the "jitters" is because this mount has rotary dampeners, in each axis. I've noticed the same sort of jitter reduction with the MC6500PRO mount, which has similar dampeners. What also helps is the roughly 2:1 reduction in each axis. Still, if you look for it, you can still see the drifting, once the GPS is locked on.

I hear that DJI has identified the problem. It is because once the GPS data is factored in, it is causing a .1-.2 degree change in the IMU attitude data. they can fix this with a mod to the IMU firmware, but for obvious reasons, it would be much better to do something on the MC end to take care of this. A small, or maybe even settable, artificial dead-band adjustment for the gimbal outputs would certainly be one way. In any case, they are looking at this, so hopefully there will be a software update coming that will address this issue, sooner than later.

I finally got the chance to go out and fly my hex for the first time, and I have to say that after trying to get an XA flying well, this was a dream. I powered it up and waited about 12 minutes for the 3 red blinks to go away, but they never did. I then flew around for a while in ATT mode, but I could never get any satellites, and just gave up after I went through 2 packs. It was a clear day in a big open field w/o obstructions or any nearby metal.

Nice job Gary, looks like your persistence paid off. Now that they have an idea what is causing the problem they should be able to fix it. I wonder how they didn't notice it while testing the new magic gimbal.

First you have to set travel adjust and then make 2 diffrent mixes, look at the picture att.

I hope DJI will come with pwm adjusted mode for all modes include IOC, then we need only use one singel channel for all modes. I have made 6 diffrent modes with this two switches earlier.

look in dji assistent for high lighted blue for every mode, if not trim a littel bit

I hope you enjoy it

I don't think you would FPV with it enabled.
This guy has produced a nice vid with it in action.

Intelligent Orientation Control (IOC), or carefree (MK) is good if you fly outside the visible range

It also works well for A/P as long as you remember to keep it in front of you.
