I don't think they run, First flight with my sons it was set on beginner mode, well it wasn't lifting up so I pushed the stick a little further. Well it reminded me of those satellites it went vrrrrr straight up, wind gust got it and threw it on the roof. I was standing maybe 10 feet from my house. So I tried out my fishing skills and pulled it off the roof. I would have tried to fly it off but it was upside down.
