Agricultural Drone Maintenance Cleaning

Avionics System Maintenance   1. Use alcohol wipes to clean the dirt from the connectors of the main control, power distribution board, radar, FPV, ESC, and other modules. Allow them to dry before reconnecting.   2. Inspect the wiring harnesses of the electrical modules for damage. Ensure that the RTK and receiver feeder harnesses are not bent or broken.     3. Use alcohol wipes to clean the electrode copper sheet interfaces of the power distribution board to remove copper rust and black arc marks. If the copper sheet is noticeably burnt or split, replace it promptly.   4. Check if the screws securing the power distribution board and avionics modules are loose. Tighten any loose screws and replace any stripped screws.
