I have just been flying with them
The only problem I had was I was using a tablet screen which made flying very difficult and I kept having to lift the Goggles up. I have just got a
GameSir controller so can't wait until tomorrow and fly it properly
.
I used an old tablet with HDMI out and a converter cable (Female HDMI to micro HDMI) to go intp tablet and then the supplied DJI lead to go to Goggles.
I did a bit of research on this earlier as I thought I could get a cable for my new phone USB-C to Female HDMI but unfortunately the major phone makers have removed the protocols to handle HDMI on most modern phones. There are a few that can do it (Galaxy Note 8, S8 or S8 Plus, Huawei Mate 10, Mate 10 pro). You need DP alt mode.
