1. Pre-Flight Maintenance Checklist

Inspect the Drone Body

Before flying, examine your drone for any visible damage, such as cracks or dents in the body or arms. Ensure all components are securely attached.

Check the Propellers

  • Cleanliness: Remove any dirt, debris, or grime from the propellers.
  • Integrity: Look for chips, cracks, or bends. Damaged propellers should be replaced immediately.
  • Attachment: Ensure the propellers are tightly secured.

Battery Check

  • Charge Level: Fully charge your batteries before each flight.
  • Condition: Inspect for swelling or damage. Replace faulty batteries to avoid mid-flight failures.

Gimbal and Camera Inspection

  • Gimbal: Ensure the gimbal moves freely and is not obstructed.
  • Camera Lens: Clean the lens using a microfiber cloth to prevent blurry footage.

Firmware and App Updates

  • Firmware: Check for and install any available firmware updates for the drone.
  • App: Update the DJI Fly app to ensure compatibility and access to new features.

Calibrate Sensors

  • Perform a compass calibration and, if necessary, an IMU (Inertial Measurement Unit) calibration in the app. This step ensures accurate navigation and stability.

2. Post-Flight Maintenance Practices

Clean the Drone

  • Use a soft brush or compressed air to remove dust and debris.
  • Wipe the drone body with a damp cloth if it’s dirty, avoiding electronic ports.
