well, compared to the first video (initial flex 3), the feeling was like if the flex was on the whole board, on this video it feels more snappy on the flex and less bouncy. I jump way harder on this one by putting more pressure on the feet. Good news is that I seem to prefer this flex which is less bouncy but more predictable; I would say that the area of flex on the board is more like a rectangle whereas on my first video it was more "spheric".
can't wait to have my electronics to try this electric powered !
