I just bought a Typhoon G and I can't get the video to display on my controller. I just talked to tech support for Yuneec and he said that I may have too new of a Gopro firmware. Is this true and what version do I need?
GoPro released a firmware which disabled the video out signal on the USB connector. This was apparently a mistake and a subsequent firmware was released that re-enabled the video out through the USB connector.
If you make sure your GoPro is updated to the lastest version you should be OK
Once you've done this, also make sure that you have AV out enabled in the settings of the GoPro.
