DJI Agras MG-1S
About the DJI Agras MG-1S
DJI Agras MG-1S is a 10 L agricultural spraying octocopter introduced in 2017. DJI lists 10 kg aircraft weight without battery, 23.8 kg standard takeoff weight and 24.8 kg maximum takeoff weight at sea level. With the MG-12000S 12,000 mAh battery, its published hover tests are 22 minutes at 13.8 kg or 10 minutes at 23.8 kg near sea level with wind below 3 m/s. DJI’s product page gives a 1 km controller reference without a region label, while the separate English user manual lists up to 1.5 km FCC or 1 km CE/KCC/TELEC/SRRC for the DLG60A link, unobstructed and interference-free. The separate MG-1S RTK variant adds D-RTK capability and has a different battery-excluded airframe weight; confirm the exact variant before selecting parts.

Common Failure Modes
Symptoms: Uneven spray pattern, blocked nozzle, pump noise, or fluid leak.
Likely areas: tank, nozzles, pump, hoses and seals
Flush and inspect the fluid path before replacing electronics; follow chemical-handling precautions.
Symptoms: Cracked arm, loose fastener, rough motor spin or abnormal vibration after impact.
Likely areas: arms, motor mounts, propellers and landing gear
Keep the aircraft grounded until the load-bearing structure and propulsion system are inspected.
Symptoms: Intermittent DLG60A link, position warning or radar warning.
Likely areas: controller pairing, antennas, GNSS/RTK configuration and optional radar
Verify the exact standard or RTK variant, firmware and environment before selecting parts.
Repair Notes
Drain and flush the spray system using the appropriate operating procedure before service; wear suitable protection for residues.
Check the aircraft label and whether the unit is MG-1S or MG-1S RTK. Do not infer interchangeability from similar MG-series appearance.
Remove the flight battery before opening the aircraft and inspect connectors for damage or corrosion before reconnecting power.
Complete the applicable calibration and controlled low-altitude test before returning the aircraft to spraying service.
