So I bought a 3DR solo since I had a GP3+Black edition. Couldn't pass up the BB deal at $299 for such a great drone. Either I am really unlucky or I am missing something. So I installed the gimbal, updated all the firmware on the solo, running V3.03 on GP, set video to 1080/30 medium view, turned on drone, then radio then connected my solo app on my iphone to the wifi, made sure it was on Hero3+Black. All good but my live feed is black. Checked all connections, powered the GP on an off, switched from 1080 to 720 to 1080 again. Powered everything off and on, restarted app, uninstalled and reinstalled app, disconnected gimbal and plugged solo hdmi directly into GP still black screen in solo app. Checked hdmi out on GP with cable to TV and didn't work. Aha! Got it!...So I go buy a Hero4 Black edition put V3.0 on it, install with just Solo hdmi cable directly into camera...Same shit! Try the gimbal for the hell of it...no luck. So now I am pissed and drive to BB and buy another 3DR solo and get an extra gimbal on top of the one that comes with the second drone. So now I have 2 drones, 3 gimbals, 2 GoPros, and have been mixing amd matching and taking things apart and making sure all connections are tight and still have a black screen. The best I get is full control of my GPH4B in the gimbal, start stop record, powers on and off but the live feed in my solo app is black as are the recordings on my camera roll on my phone with no sound. The same videos on my SD card in the GP are fine. So could it be my iphone 6 running Ios 9.3? Let's try my girlfriend's iphone 6s running ios 10.2 and install the solo app....Nope! Not for this guy. So am I just really unlucky and just happen to buy to 2 f'ed up Solos, 3 f'ed up gimbals and own 2 f'ed up GoPros...or am I just stupid and missing something? I'll admit that this is my first drone but I am not new to building RC cars and planes not to mention computers and fixing my own iphones when shit breaks. I have read through a ton of these threads and looked online and tried all the various fixes. I have yet to find somebody with this problem. Help 3DR Experts!
