Inspection Checklist

Model identity

Read the exact printed controller model code and match the aircraft generation before pairing.

Controls and ports

Check stick centering, mode switch, gimbal dial, physical output ports and mobile/display path.

Battery and radio

Check charging, antenna integrity and a safe short-range link with compatible current firmware.

Common Failure Modes

Wrong controller generation

Similar housing does not prove compatibility; compare the model code and DJI transmission generation.

Control or display fault

Damaged sticks, output ports, display, antenna, battery or stale firmware can interrupt the link.

Repair Notes

Confirm exact aircraft/controller labels and firmware before diagnosis.
Retest stick calibration, output path and a controlled short-range link after any repair.

Pre-Owned Buying Checks

Verify the printed model code and correct aircraft generation.
Inspect sticks, outputs, display/phone mount, antennas, battery and charging.
Confirm pairing and no current stock claim from the Wiki profile alone.
