Helicopter / Plane / Drone Spinning Blades
Spinning blades - isolated to add to: Planes, Helicopters, Drones, SciFi Vehicles (and even vents!).
Different speeds, sizes; Blades start up, Blades slow down to a stop.
Also dynamic shots, like starting from above and going to a side view.
To add to 3D and prop vehicles or many kinds. Can't find this type of thing anywhere, it would be awesome! (and very useful)
