Matrice 300 RTK and 350 RTK Complete Repair Guide: Common Issues and Parts
The DJI Matrice 300 RTK and Matrice 350 RTK are the benchmark enterprise drones for surveying, inspection, and public safety operations. With IP45 weather resistance and support for multiple payload configurations, they are built for demanding environments. This guide covers the most common repair scenarios for both models.
Arm Motor Issues
Symptom: Motor error code / one motor not spinning / drone unstable on takeoff
The Matrice 300 and 350 RTK use high-power brushless arm motors. A motor error on a specific arm indicates motor failure or ESC fault on that arm.
- Arm Motor Compatible with Matrice 300 RTK — SKU m300rtk
- Brushless Arm Motor Compatible with Matrice 350 RTK — SKU SKU00017
Before replacing the motor, analyze flight logs to confirm it is a motor fault rather than an ESC issue. See our guide on reading drone flight logs to diagnose crashes.
Cooling Fan Issues
Symptom: Overheating warning / thermal throttling during extended operations
The Matrice 300 and 350 RTK use internal cooling fans to maintain safe operating temperatures. Replace fans showing noise, vibration, or reduced airflow.

Propeller Issues
Symptom: Vibration / noise / propeller damaged after crash
Always replace propellers in matched pairs. The Matrice 300 / 350 RTK uses large-diameter folding propellers.
