This is not really feasible as the whole bell turns, difficult to atach a duct. Long time ago, @superlefax tried a prop with a protecting ring attached to the blades but it did not work, it was too inefficient.

> I already tested this idea The consumption is a nightmare! I was really surprised on this. It is a modified hiorth propeller. Without spinning duct the hiorth propeller needs 38A @ 20 km/h on my setup. With the spinning duct it is 100A @ 20 km/h. I think there is no chance having an efficient propeller with spinning duct if it is 3D printed.
