I was out for a quick flight today. It is Sunny and 85 degrees F. I noticed after about 8 minutes my video link started to get very slow and pixilated. I am using an Iphone 6 without a sun visor. Same thing yesterday, during quick mid day flight. I flew yesterday evening when the sun was going down and video link was perfect. I assume my Iphone is getting too hot and its interfering with picture quality. Anyone else?
