I made this as a way to replicate the DJI s900 Drone from DJI, but for a few reasons I decided to make it slightly different, most of all mesh optimization.

This model has been UV mapped and is textured using only the Color (Albedo) and Normal Textures, but the rest of the PBR textures are included in the ZIP file so you can make the most convenient setup for you (Blender internal / cycles).

It’s rigged and all the arms / propels have a “follow rotation” constrain so they follow the Arm.000 and Propel.000 bones, that way you don’t have to animate them all.

 It’s made for Real-Time rendering on game engines, but setting the right material setup it’s going to look pretty well in any of the render engine blender has.
