Aerial Quad-rotor Automated Drone 3D model

This is a quadrotor drone concept based on a old sketch I made. I created the model and assembled the textures using Blender 2.9.1.2 as a challenge to make something more complex than my previous drone model, this one having 4 rotating engines and arm mounted energy beam emitters. The model and animations were imported into Unreal Engine 4.2.6 to try thruster flame effects and since I may use this design for a video game I've been working on and those are not included with the files I uploaded here. The textures are solid colors and a 2048x2048 normal map.
