DJI Agras T20P
About the DJI Agras T20P
DJI Agras T20P is a 20 L agricultural spraying and 35 L spreading aircraft. DJI lists 26 kg without battery, 32 kg with battery and maximum takeoff weights of 52 kg spraying or 58 kg spreading at sea level. Its Specs page lists 14.5/7/6 minutes of hovering at 32/52/58 kg with a 13,000 mAh battery; DJI’s separate FAQ lists 16/7.5/6 minutes at 31/51/57 kg. The official pages do not reconcile these test figures. Its RM700 O3 Pro controller link is rated up to 7 km FCC, 5 km SRRC or 4 km MIC/KCC/CE under stated signal conditions.

Common Failure Modes
Symptoms: Cracked shell, bent arm, loose landing gear, abnormal vibration, or visible crash damage.
Likely areas: outer shell, arms, landing gear, motor mounts
Inspect the airframe before powering on and verify the exact replacement part against the model variant.
Symptoms: Motor start failure, rough spin, propulsion warning, overheating, or unstable hover.
Likely areas: motor, arm wiring, ESC board, power connectors
Check for impact damage, cable strain, and water exposure before replacing boards or motors.
Symptoms: Flow error, pump warning, uneven spray, nozzle blockage, or tank/payload warning.
Likely areas: pump, nozzle, flow sensor, tank, payload wiring
Clean fluid paths and confirm sealing before replacing electronics.
Symptoms: Positioning drift, obstacle sensing warning, compass or IMU calibration prompt, or unstable low-altitude hover.
Likely areas: vision sensors, IMU, GPS/GNSS board, sensor flex cables
Clean sensor windows and verify calibration after shell, sensor, or board replacement.
Repair Notes
Confirm the exact model, variant, error message, and visible damage before selecting parts. Do not substitute parts from a similar model without verification.
Remove the battery before opening the aircraft. Check for moisture, corrosion, and overheated connectors before reconnecting power.
Clean pumps, nozzles, hoses, and flow sensors before assuming an electronic failure.
After replacing gimbal, vision, GNSS, IMU, shell, arm, or propulsion parts, run the required calibration and perform a controlled low-altitude test.
