Also interesting is that in the shots that show the underside of the board, it clearly shows six, possibly seven outlets (four/five in a central group and one either side) expectedly four/five for vertical thrust and the outer two possibly for vectoring. One could easily presume that there are six turbines/motors. Definitely looks like the backpack is fuel as the pilot seems to do a fuel check by lifting the bag with his left hand on a couple of occasions.
