i have a Q500+ and I believe it is set up to only fly certain distance. I remember reading that in smart mode it will only fly out 300 feet. I don't fly in this mode at all. I have taught myself to fly in angle mode and am pretty good at navigating in thinking quick which way to turn in order to avoid a collision. I feel I've been able to master flight orientation pretty well when beyond a distance were you can't physically see front from rear. I always have a fear of flying to far. I don't know how far is? I'm not sure in angle mode if there is a distance limit. Is it 400 feet? I think I can adjust it so it is longer then that or higher then 400 feet but maybe I will try that at some point. So I think my question is... How far will you fly out before you know it's time to turn around. In other words, will you be flying and then all of a sudden loose your video like the same as you turned off a television. Going from a beautiful image to boom!!! Gone!. Or will the video gradually flicker and give you some type of warning that your close to the edge.? And info in this regard would be appreciated along with recommendations for antenna options that would provide a better capability of extending video as well as distances. I also believe it is good to stay in LOS with your typhoon but I do eventually want to be able to fly in recognizing first person view. Not to make a habit of this but to do it practicing so I can learn effective navigation skills. I realize this is a bundle of various questions so I appoligize for that.
