I have the P4 Pro since last November now. So I'm reposting this thread in the P4P area to get more eyes on this issue. Never used to have transmission glitching much at all. Now in the last 2 months or so after some Go 4 updates I am having way too much transmission issues when bird is no farther out than a few hundred feet! I still have the Ipad Air 2. Mainly using 5.8 ghz band. 2.4 doesn't work as well anywhere that I have found. What's going on with this?
