Yea, I saw this video too. It would unnerve me to no end to fly that distance. Of course, even with the 4Hawks, I can not even get a third of that distance which is fine because I don't trust the batteries I have to make it that far and back. I also ended up playing around with my 5.8g antenna that's located inside the camera housing. It appears to me that it's design is pretty bad. They placed the antenna in the front of the camera so when you're flying away from your signal and the camera is facing forward, you lose signal pretty quick. I ended up allowing my antenna to sorta just hang off the bottom outside of it's housing to see if it made any difference, which it did. Not that even that matters because I put it all back together afterwards in the way that it originally was. I feel like if I made any permanent modifications to the camera housing to allow the antenna to hang from the bottom it would mess up how the camera turns.
Anyway, yea videos like those are fairly mystifying to me. I'm not too sure that the 4hawks was the only factor that allowed such distance.
I work in an establishment with only 3 men and 150 women, for peace I embrace my feminine side, when I get home I'm outnumbered again, so for an easy life I put on my feminine coat.
You poor soul! ?
