Sounds about like my first experience with my cheap-o Radio Shack (RIP) drone. Kept hitting stuff in the house, so I though, "I'll take it outside. Never mind the snow on the ground. It'll be easy to find that way and it's open skies." Spent at least an hour combing ground in the neighbor's yard til my hands and feet were numb from the cold. No luck. Wife goes out when the snow melts and finds it right away. Still works.
We've got carpet in every room of the house except the bathroom. The stuff in the dining room/kitchen is the tightly packed stuff, but I'm not sure how the more plush stuff in the living room will affect this thing. Might start off in the garage.
I've watched their Tutorial video a couple of times. They recommend pumping to get it going so you don't have to try and compensate for the force of it accelerating from a standing position.
What could go wrong?
