DJI Phantom FC 40 with brushless gimbal , test flight 

1. Just mount on Phantom. I use two cuted wires that you can see on phantom, for power source, and connect with only one signal wires from gimbal to Naza controller inside phantom for pitch function (also you will need to install leveler to rc controller) You can find tutorial videos on you tube for this 2. Settings for BGC that I use, you can find here (it is my post): www.djiguys.com/Forum/viewtopic.php?f=42&t=4228 Most important that at the end, I lost my nerves, because it is cheap, but not good solution, I had many jello started with light wind , and at the end I buy used Zenmuse 2 Axis, upgrade FC 40 board and buy GoPro. After that all is excelent, expect that I wish 3 axis gimbal :P If you still want to try, CNC gimbal and FC 40 camera, maybe is better to try factory GoPro settings in CNC gimbal, and add more weight and balance to mounted FC 40 camera, then to try setting BGC, because metal gimbal is is not balanced for low weight FC 40 camera

This brushless gimbal, as most of gimbals came pre set for GoPro 3/3+ . For other cameras, this gimbal that I use, must be set up by user. I dont try to use it with GoPro 2, must to ask someone else To enable tilt camera by RC, you must connect gimbal with signal wire directly to Naza conntroler in quad (you must to open Phantom, it is not hard, as it looks ) :) , after that do calibration in Naza Assistent software, and of course to buy leveler for radio control device (transmiter), or use screwdriver for test :) 3.bp.blogspot.com/-SonJePEYc9Q/U352EYsefjI/AAAAAAAAAfY/SdY66TB2vcA/s1600/fc40-front.jpg
