This 3-d model is dubbed 'Torque-wing'

The bigger 6-bladed air-wheel, can carry quite a load,
using two axels, to ballance more effectively.

The rear-rotating wing, gives perfect VTOL,
when moving in the opposite direction
to the larger front wing.
This particular design is in theory, more than practice, as I have not the capacity to build a powered air-wheel, yet.

Please go ahead and develop this concept freely, but you'd be better off getting my input, as I have concepts that go quite far beyond these precursor designs.
