Hi Guys, this is a video of JB's new Quad Copter design. This is its maiden flight and most likely its last flight in Australia as it is heading to they US in a couple of weeks time. One of the American's from work got jb to build one for his son . . not a bad gift from Australia hey. In any case it look pretty stable . . . in fact I think it's even better than his Tri-Copter. . . the one that crashed in a lake lol
