My first attempt at flying one of those would probably look like that too, but it would just be totally out of control. That looks like a good way to get yourself and the spectators killed, just as dangerous as a motorcycle in bad hands. (Joke, in case someone didn't know).
Danny, looks like someone stepped on or rode over your helicopter. You fixed that? I guess most of the body work is replaceable but what about engine and rotor mechanism damage in a bad crash?
What kind of fuel supply do those helicopters have to enable them to fly upside down without gas spilling all over or not getting to the engine from the tank? Yours is electric, the one in the video looked like a gasoline engine with exhaust smoke coming out (2 stroke).
