As soon as my drone takes off the video is horrible. I have both antenna tilted up so they are not pointed at the drone. Is my Ipad too slow to process the image data? The same thing happened with my P3Pro, so I'm sure it's me.
If before taking off videos are ok, and go bad during flights, the problem is in video streaming. Cause could be local interference to your signals. Move to another open location and try.
