ok i have a basic propeller facing the ground, im looking to make this spin so fast it generates enough lift below it to "hover" off the ground.
are there any lightweight motors i can get made for this kind of stuff? what kinds of rpms am i looking for? is it possible that a company would be selling gearboxes made for speed rather than for reduction (torque)?
any general to specific info is helpful. im making a hovercraft to float off the ground, using 3 propellers but im not sure about the motors ill need and what kind of electronics/battery with it.
