Nice!! great job. I have Tarot Gimbal, the video if fine just cant seem to get my quad to behave... more reading I guess

Thanks for sharing.

Looks great :)

Would you mind posting the settings you have set on the Tarot? I'm trying to fine-tune mine!

HI Alan,

I found this youtube video to be gold for the Tarot. Everything I tuned in came from here. I find that every setup is different but if you follow this along you will have great results.

Hope it helps.


what yaw PIDs are you using? I see some oscillations

Are you flying with the Flysky controller or something else. I am finding it very hard to control my Gimbal it won't tilt.

HI Michael,

I have tried to get my Gimbal to tilt with out a lot of luck. Connecting the right pins to the Pixhawk controller I found the Gimbal to be erratic. The are allot of fixes out there including making sure the right voltage is being used. (put a meter on your BEC if any they don't always put out the right voltage.

Channel 6 is used and recommended with a turn switch to adjust the angle correctly. When I configured mine there was a big delay the camera would tilt and go back to its original position, or just start being very erratic. In the Tarot software it does let you choose stick position and one other option...(Cant remember)

This guy got it working with his DJ Phantom but not with the Pixhawk

If you find a solution let us know. I will have another go at it and see what I can find.

Neil, thanks for the video link, will take a look in a minute.

I tried to connect the Tarot to my APM, and also found it erratic as you describe.

Currently it's connected to channel 6 or the receiver, and by setting the flap limits on my DX6i I can get it to move between 2 positions fine. I set the 'stick position' setting in the Tarot config, as well as the RC sensitivity at 25 I think to get slower camera movement.


settings on the gimbal itself are stock settings from 3DR. I went with the assumption that they've set the firmware and settings for the IRIS before leaving the station. Turned out to be true enough.

edit: If you mean the PIDs on the gimbal itself I haven't pulled it's settings. Probably these:

Yep, using FlySky. You need to tell your Pixhawk / APM controller that you're using channel 6 to control tilt.

This section in the Gimbal setup instructions worked for me:

If that doesn't work, either your controller isn't set to send on Channel 6 or you need to calibrate your radio in Mission/APM Planner.

or your gimbal needs some preferences changed.

or... :)

thanks! Pretty happy with how it's working. I'll have some more video from this weekend.

IRIS Stock radio is configured out of the box for tilt control however it is advised to disconnect the roll wire from the Pixhawk.
