I have 5 flights under my belt now 4 using an iPhone 6 Plus and 1 today using an iPad Air 2. The iPhone 6 Plus flights were faultless video etc perfect in every way. Wanting a bigger screen I thought I'd use my iPad Air 2. I set it up as normal but my iPad doesn't have a sim installed so I tether to my iPhone via Bluetooth for the internet access (I wanted to test live stream to YouTube). The video feed though was not as good as normal. I had moments of blocky picture and lost video completely a couple of times. I had full bars at the time on the Lightbridge so think it was the app. Was the Bluetooth interfering possibly or do other people set up this way? I heard on one video on YouTube that he puts his phone into airplane mode when flying but cant find it now to ask him why!!
