Fly aways can happen with any brand. I've had a few phantoms try to run away from me. I know I'm ugly, but I can't be THAT ugly, can I? I haven't had any fly aways with my Evo, but I had 1 battery damage as I was taking off. Watching your drone go up into the sky, while indicating RTH, is a very scary thing. Strangely enough, as it started going down, it stopped at the 10' height and just hovered there. Wouldn't respond to any of my commands. I had to grab a ladder and flip it over to get it home. Usually when you put the hand underneath, the drone raises when it senses you. It didn't this time.
Anyways, back to the main topic. I would like as much detail as possible and if possible a video of the flight log
@daveglow. I'm not doubting you at all, since I know these things happen. I am just curious what were your circumstances and to see if we can pinpoint where it went wrong, so other pilots can learn from your experience.
