I have noticed the distance that I keep a video feed varies. During one flight yesterday I was basically flying straight up five feet from where I was standing and got nearly 900' before I lost video signal but the altimeter kept working as I went to about 1050'. hen on a later flight I could only go up about 400'' before losing video signal and the weird thing is I would have to bring it back down several feet to regain signal. I did update the Vision App yesterday, said it was only bug fixes. The 900' was the highest I have gone before losing signal on many previous flights its been much less before dropping out.
