Holybro Kopis enhanced ducts

thingiverse

These are enhanced ducts for the Kopis Cinewhoop. The shape of the duct compresses the airflow on the base and the top increases wing effect. It also reduces the distance between the blades and the duct itself so less turbulences are generated. At least in theory. I use the original PIDs and it seems to flight better with these on. I don't know... it is worth a try.
