Raqia-Design
Gravity is the result effect of spin and or absence of it, down to the molecular levels. the faster you spin any! object, of any size, if you can, the less it will appear to weigh, as the forces move from the central location of the object [axle] outward, more than they move downward. you can spin something faster than it can actually fall. a drone of ten kilos falls slower than a piece of paper folded up like a ball. if you can spin your microwave oven around its center fast enough, it will appear to weigh less than when not spinning. its more about intent of intelligent design, than anything out of the ordinary naturally.
rotors are made of lightweight materials, but if they become heavier, they will behave more like flywheel gyroscopes. this takes more effort to move and rotate initially, but is also very hard to stop from rotating, and if the mass of rotation is heavier than the object it is mounted on.... it will influence it surely. the larger spinning mass turns more dominant in force than the device it is mounted on. the bigger mass just has the most influence over direction. same as how two masses behave in space, where one pushes off of the other, or it only pushes off itself, when being the smaller mass of two.
