    I am about to test two servos for camera gimbal control on my F550 c/w Naza M-GPS including the V-sen to manage the electrical power distribution. I am looking for some direction as to the configuration of the hardware and the RC transmitter.
    I am using a R6208SB in FASST MLT2 configuration and intend to use Tx channels 7 and 8 for control through to the Naza F1 and F2 ports which will accomodate any type of servo unlike the other channels which are restricted to digital in this mode. I am following the details on page 26 of the Naza version 2.4 manual. Has anyone here done this already and is able to provide more detailed info.....? I have more challenges with the RC system than the Naza which seems quite straight forward. An online video would be excellent.

    I'm on the exactly same page as you right now. Let me know if you found any info as a video etc. The NAZA instructions are limited.

    I'll so the same if you haven't yet found a result.

    Cheers.

    All issues resolved now...... It's much simpler than I realized. Just plug the gimbal servos into Naza ports F1 and F2! From section 5 of the manual, subsection 3. After adjusting the servo directions and centerpoints per section 5 (2) Gimbal set the F1 and F2 gains at 10 each and X1 Manual control speed for X1 in section 4. @ 50. The gimbal assembly will automatically level your camera for you when flight battery is connected to start Naza. But you can still override automatic control of pitch by means of X1. Remember to de-activate x1 control of remote adjustment of pitch/roll gain per section 4 or you will be detuning vehicle gain during flight. Also look for Jon DesJardin's excellent Youtube videos on configuring your complete system using Futaba T8FG super....

    Can someone share some documentation on how to do this. I currently have a tarot 690 with gopro tarot gimbal 2 axis. I want to change this out the a three axis and handle other cameras (black magic pocket). But the controller I have is the futuba 8 channel and I currently use the dial in the center to handle the tilt. I now will need another port to handle the third axis to turn the gimbal. But I am not sure how to configure this. Can you link me to the manual you speak of here to get me started?

    Here is the gilbal I want to move to:

    IMHO - The DJI built-in gimbal control was originally developed for servo controlled gimbals that did not require a dedicated IMU on the camera assembly such that the internal FC IMU could be utilized. The more recently developed BGC, i.e., brushless gimbal control systems (both two and three axis) require their own IMU specifically required for camera cradle mounting making the built-in DJI IMU impractical.

    There is another issue that seems to continually crop up with the DJI FC built-in IMU control algorithm...... when switching back and forth between RC remote gains control and gimbal control there seems to be some interference with flight control such that the MR will buck like a bronco in certain control modes such as RTH. This might potentially lead to full loss of flight control. According to feedback I received from my DJI WKM vendor..... a particular reconfiguration procedure had to be carefully followed to clean up this mess so that RTH could later work correctly without the re-activating the hidden extra bucking bronco feature!!!

    Personally I can't trust this DJI feature and avoid using it altogether.

    You can pass through gimbal control to the Tarot controller, just set the gimbal gains to zero, you can also adjust centering of the Tarot roll via the Naza interface by adjusting the mid point.

    Yes, I've got mine setup this way and it works well. So, I gather that only manual pitch control is available connected to the NAZA, and roll is basically setting the limits/center point without a way to do it manually?
