Hi, I am very lost on how to install my feiyu tech 3dmini gimbal on my iris plus as there are no directions online that will help me. For the pixhawk i am pretty sure the white (heading control) gets plugged into the first pin on the aux out on the bottom (signal) and the blue wire (pitch) is plugged into the next pin on the bottom (signal pin) The brown and black wire is plugged into the third pin (brown on the signal pin and the black on the ground). But how can i make it so the remote of the iris can change the tilt pitch and yaw of the gimbal? I could really use a walkthrough of this with mission planner and how to setup channels without messing everything up and how to do this correctly as I have already have spent countless hours and another gimbal. Please give me some help. If you need me to post pictures I will.

Outlines what I have done on a Pixhawk to try to get it running.
Ian, I set mine up just like the wiki says. http://copter.ardupilot.com/wiki/common-tarot-gimbal/#set-up_throug.... Ignore that the instructions are for a Tarot because mission planner doesn't care. Its only the pitch of the gimbal that I or the Pixhawk controls. The pan just follows the nose of the Helicopter. I would have to rework my landing gear to use the pan feature.

So have you selected Servo Gimbal on the setup page?
I'm trying to get the ROI to work from MP or Tower so having the gimbal stuck to the heading is not much use.
Ian, That may not be true. Your copter will point at the ROI as it moves around it. Depends on the parameter set up I suppose. I don't think the code for Helicopters and Multirotors is different in this respect. You have to select servo gimbal on the setup page to "calibrate"the PWM out of the pixhawk to adjust at least your gimbal pitch accordingly. That page has your min PWM and max PWM that will be sent to the gimbal. This may be your whole problem. Not sure but just trying to help.

Hi David
Thanks for taking the time!
I have made some headway!
1 - the camera pan and tilt feedthrough channels from the RC can be set to just about anything in the perameter list. This is not evident from the wiki notes nor from MP itself. One gets the impression that you are limited to 6,7 or 8 as those are repeatedly talked about and presented in the MP setup. I went into 'Full Perameter Tree' and set MNT_RC_IN_PAN to 13 and MNT_RC_IN_PAN to 14 and a servo plugged into RC9 started to respond to my inputs! This is great because the setup allows MP to select the functions for Ch 6,7 and 8 from the dropdown list.
2 - The feiyu gimbal has two firmware options. It got messy here as I could not connect to the gimbal using a bench power supply as there appears to be an earth difference between the PC and the PSU so the USB adaptor for the gimbal got all bitter and twisted about it! After sorting that out I flashed new firmware to the gimbal. One is a speed mode and the other is a position mode. so RC inputs control speed of tilt or absolute position of tilt BUT and here's the kicker ...... pan mode is always in 'speed' mode! Flashing the 'position' firmware only gives absolute position in the tilt mode not in pan. Mail sent to Feiyu about that, perhaps they can come up with an absolute pan mode as well.
I can work with this though. Using ch15 to select the mount mode I can put it into 'heading lock' and let the PH control tilt and rotate the airframe to point at the ROI as you said. If i want to point the camera at something whilst flying 'forward' I will have to manually adjust a pan position and tilt.
Ian, Glad your making progress! One thing I'm not sure about is if your gimbal is set up with the pan in MP's gimbal setup page the gimbal may just pan to the ROI instead of the whole airframe. See the wiki. http://copter.ardupilot.com/wiki/common-mavlink-mission-command-mes....
Good luck!

Seeing as there are settings in MP for a gimbal, what is the advantage of using them, and running the signal through an APM or Pixhawk?
I use a Tarot 2D wired directly to the receiver at the moment, but it would be great have the FC control the gimbal in auto flight modes, much the same way as it does with the 3DR Solo....... Is it possible?
Like he connects it in this video, https://www.youtube.com/watch?v=93wuN27OFFU
David, The advantage of running the gimbal control through the pixhawk is the advantage of Auto missions being able to control the gimbal. It makes it possible to use the ROI feature. See video link below.
