quadrotor drone 3d model

Design a realistic, buildable autonomous delivery drone called AERONE, based on current commercially available multirotor technology. Use a practical quadcopter configuration with four large brushless motors and propellers, preferably protected by aerodynamic duct/guard structures. Create a lightweight carbon-fiber or aluminum internal frame with removable injection-molded or composite outer panels. Include a realistic battery compartment, ESCs, power-distribution board, flight controller, GPS/GNSS antenna, telemetry module, obstacle-detection cameras/sensors, cooling airflow, wiring channels, service panels and a mechanically simple locking cargo box. Keep the center of gravity close to the geometric center and distribute batteries and electronics realistically. Include four robust landing legs with vibration isolation. Use commercially achievable dimensions, motor sizes, propeller clearance, fasteners, connectors and manufacturing tolerances. Every component must have a practical eng
