Man I have to build one of these......and I am going to be 50 in a few weeks and i think my wife has taken all my quadcopter hints seriously because today a 450 frame fell through the door.....yipeeeeee
I agree with earthsciteach: how do you know the orientation?
Watching this shows how dynamic these things are. Goes from doing backflips at +40mph to hovering perfectly still. Sweet!
So who is going to be the first and put constant speed variable pitch rotors on a quad copter and fly inverted? Or even reversible esc's for that matter?
By where it has been and what it is doing on account of what your thumbs just did. As per many comments on the youtube page, that sort of flying needs jedi reaction!
