With my headache right now, I can't watch that. But I assure you, it's a full range Rx. Even more so if you run a satellite rx on it. I'm running the Sat on my 600N just because it's a 600N and not a 450 lol.
However, if you are looking for long range fpv, then 72mhz is the best option with a 900mhz video system. From what I read, this I do not know for a fact.
And remember, there is always a video of something happening to something. I'm sure somewhere, there is a video of a porche with a wheel that has fallen off or something lol. It's very rare, but it does happen.
