Question: What do I need to connect this gimbal to my stock DJI Phantom FC40?
Document: I have had the product for about a week now. (mounted to a DJI Phantom) The gimbal can be a bit unreliable at times. I have found that for some unknown reason it will tilt way too far back or chatter alot when i first hook it up. Sometimes it corrects itself, sometimes it doesn't. Keep in mind that I have not hooked it up to any kind of software and this is my first quadcopter and gimbal.
Doesn't seem to function the way it is supposed to. The gimbal sputters pretty badly and the tilt control is completely useless. Overall my entry into ariel videography has been more or less a complete nightmare between this gimbal and the DJI phantom that I purchased. Unless I somehow managed to acquire $5000 to dump into a drone/gimbal system, I probably will not make leaps forward with this area of cinematography.
This Gimbal came in a box, in pieces, with paper stuffed around it. No instructions, parts list not even a brand. I haven't installed it yet, not even sure if it is all there. Searching the net for instructions on assembly and where to plug power.
No instructions came with it, I sent an email to the seller asking them if they could send me some instructions and what they sent me was a link to download a torrent Downloader plus about 5 other links that kept telling me to download things. I finally found a video online and got it put together. The gimbal is extremely shaky, so shaky that it's pointless to even try to film with it. Even though it's cheap for a gimbal, save your money up for a nice one.
It seems to be a solid product. I actually didn't get a chance to use it. I bought a Phantom 2 and this was supposed to be an easy install. There is no way in hell I'm going to be opening a thousand dollar quad copter to start trying to figure out how to sider wires to it.
This thing works like a champ. The only problem is that sometimes it does freeze up and it makes the Phantom 1 battery go dead in 4 minutes, but overall I would probably buy it again. I have used it a few times and then taken it off my Phantom, because smooth footage is not worth the drastically reduced flight times.
First one I got did not work, the motors would not work, the board had power, and had lights, just no motors. The replacement model had no configuration in it and went crazy. I opened the software and connected and the IMU sensor was not reading, it had a bad wire, and the calibration was all set to zero. I found a profile online and loaded it and it is working better, but I have a lot of work to do to stabilize the gyro.
Answer: This gimbal connects to the two stock holes that the FC40 camera screws to. You need to open the Phantom and find the grey and red wires that are free and in one arm of the phantom just sitting there. You connect the pig-tail they sent you to these wires and fish them thru a leg hole. This is your power for the gimbal. I soldered mine, but suppose you can twist and shrink wrap them. If you won't care about using the Phantom remote to control the pitch of the camera, that is all you need and the GoPro 3 camera. If you want to connect it to the pitch lever on the back of the remote, you need to open the phantom, connect one of the many wires they provide and fish it thru another leg and connect one end to the F1 port on the NAZA module. It will be the bottom of the three pins in F1. Then when looking at the gimbal where there are 4 rows of 3 pins, the top left pin is where you connect the other end. Then in the Naza software, you enable the Gimbal, set the travel limits you want, and install the 12$ pitch level on the back (available on Amazon). There are plenty of youtube vids on this.
