Hi, Nixie looks super cool, but without a spec it's really hard to tell how useful it is. How long does it fly? How to control it (especially during a rock climbing...)? What's it's range? How does it land? How to find it after landing? Which flight controller is used? Does it have GPS? I am super curious of the answers.
