MATRICE 300 RTK User Manual
Landing Protection will not be active in the following circumstances:
When the user is controlling the pitch/roll/throttle sticks (Landing Protection will re-activate
when the control sticks are not in use)
When the positioning system is not fully functional (e.g. drift position error)
When the downward vision system needs re-calibration
When light conditions are not sufcient for the downward vision system
If an obstacle is within one meter of the aircraft, the aircraft will descend to 0.7 m above the
ground and hover. The aircraft will land after user conrmation.
Center of Gravity Calibration
The center of gravity will shift when the aircraft’s payloads change. To ensure stable ight, it is required
to recalibrate the aircraft’s center of gravity when a new payload is installed.
Calibrate in a windless environment. Make sure that the aircraft is hovering and there is a
strong GNSS signal during calibration.
Maintain visual line of sight of the aircraft and pay attention to ight safety.
Calibration instructions: Go to Flight Controller Settings in the app, and tap Calibrate in the Center of
Gravity Auto Calibration section. The Aircraft Status Indicators will glow solid purple during calibration.
There will be a prompt in the app after calibration is completed.
Flight Recorder
Flight data is automatically recorded to the internal storage of the aircraft. You can connect the aircraft
to a computer via the USB port and export this data via DJI Assistant 2 or DJI Pilot app.
Propellers
Propellers Usage Guide
M300 RTK uses the 2110 propeller. The 2195 propeller is purpose-built to improve the aircraft’s
maximum ight altitude while maintaining minimal ight noise.
Flight altitude limit is the maximum height that the aircraft can y normally where the wind speed should
not exceed 12 m/s. Note that the aircraft's braking and acceleration capabilities are reduced near to the
ight altitude limit. Please read the diagram below to learn more about using the appropriate propellers
by referring to the aircraft’s weight and the expected maximum ight altitude.
