Multirotor Ducted Fan


Any one have try the ducted fan on multirotors?

Advantage and problems?



Yes, they improve efficiency, and safety.
No problems, except added weight AFAIK.

thanks! You know how much is the improvement?

Depends on a lot of factors !!! What kind of question is that ?

Are those ducts metal? Added weight as suggested plus ducts loose efficiency as the pitch angle changes from normal to the duct axis so on a multirotor they don’t make a lot of sense. Unless it’s a hover machine going up and down…
