Hey guys,

I currently run the Zenmuse GH4 on my S900 w/ A2, AVL58 and iOSD Mark ii.  But I get about 12minutes of fly time.  I'd like to use the Zenmuse H3-3D and my GoPro for longer flights.  

Does anyone have experience with this setup?  I've been scouring the web for a build to no avail.  I'm hoping that I won't need the Zenmuse GCU which is in my Phantom.  From what I've read it looks like I could use the Phantom 2 Hub to make the connections (although cables are too short).  

What components are needed for this setup?

As far as I know, GCU is a must. But in Phantom 2, the GCU is integrated into centre board.
So I m afraid that you need to find the dealer to get a spare GCU....
