I will have to check the vid on my pc later. Quad copters are a lot more stable but still anything that effectively constitutes a flying lawn mower deserves respect. I sold my Align Trex 450 and 600 (both electric) to help get the box, and also cuz I was done with the danger part of flying for now. Anything 500 size and up you really need a nice large space with no people around, especially when going inverted etc...
