They don't come with FPV, you can add then. I would not ever Buy DJI again. Worst customer service I've ever seen. My unit only lasted about a month. They have had it at the factory since then. They don't answer the phone or respond to email questions. I'm not sure if I'll ever get it back.
Yes it does. There is a control arm on the back of the remote control that allows you verticle control of where the GoPro is pointing. You can go from looking straight out to looking straight down. If you pair this with an FPV system you can get a live feed of what the GoPro sees.
The Gimbal pans up and down only. I would not purchase anything from DJI ever again though. My Phantom only worked for 1 month, and they have had it at the factory "working on it" for over a month now. They have the worst customer service I have ever dealt with. I can not talk to a real person, and the emails are rude.
