Hello
I bought a Phantom 2 + Zenmuse H3-3D with GoPro Hero 4 Be.
The duration of flight I want to see battery life and how many meters high?
Is it get DJI assistant app. for iphone?
or need for fpv system?
(No need real time image or video just I want to simple flight information)
Thank you

Need dell'iosd mini and a video on the phantom tx
ground instead a rx and a video monitor
so you have all the telemetry and video images in real time

What coinfaslab said.  

An iOSD module is needed to read the data from the Phantom, and from there you could go two directions.  Set up Ground Station and use a portable device to view telemerty data and control flight paths, etc.  (at least I think that's how it works.  I don't have that setup)  Or you can go the FPV route via a video tx on the Phantom, and goggles or screen with an rx on the ground.  This is the best way to get good camera shots, as you see (a low quality version of) what the camera sees.

Thank you for your help.
I ordered iosd mini today. Than what else do I need or what is your suggestion fpv kit brand for phantom 2 zenmuse h3-3d?
