in my 7 last lines i was neglecting the hold dinamic sustentation concept the same reason many people in 1900 said flying was imposible
but i was thinkin in this flow "experiments" in which water made flow in spiral tubes would show at certain speed negative friction
i think the reason your invention wont work is becasue you wont be able to crank lift to conver it to force unless the plane actually really goes up
but like lift and weight are balanced, the force with which the plane will go up (the only way to cranck it is by the plane going up) will not be lift, but will be produced by the plane going up direction and the force with wich it will go up will be equivalent to the force of thrust sent down
