I love having to take a part my phantom, NOT. I have installed the Zenmuse Gimbal and a few other goodies like the DJI AVL58 Transmitter for viewing my video (FPV) on a receiver mounted 5" monitor. Unfortunately I was to fast to close up the Phantom before I realized I needed to plug in the video plug into the GCU. So I took a part Phantom again. Now finished, I am experiencing that my gimbal is not leveling and is tilted up. Ok, go to website, look up manual, read that I should install software and do an update. PROBLEM....the GCU is inside the Phantom and once again I must take apart the body. I ran a short cable through the battery compartment and up the side to the Zenmuse GCU. I am leaving it plugged into the GCU so I don't have to go back into the Phantom for any updates. The cable is then tucked off to the side in the battery compartment just like the USB cable for the Phantom updates. I have attached photos of the setup I have with the DJI AVL58 video transmitter and remote mounted 5" monitor for FPV while flying. This runs for about 9-10 mins off one battery powering the video transmitter, Zenmuse, GoPro and flying the Phantom.
