exists, but you’re not sure whether it is safe to y,
contact DJI Support for help.
3. Check the connection between the motor base and
the arm tube.

frame arms are aligned. If the vertical difference is
over 1 cm, use the arm inclination holder to adjust
the arm inclination.
IV. Checking the Retractable Landing Gear
1. Check the servo cables for wear. Ensure that the
connection points are secure.
2. Check the power cable connector for wear. Replace
the connector or return to factory for repairs.
3. Hold the aircraft body, and then raise and lower the
landing gear to the ground several times to ensure that
the retractable landing gear can move freely.

shaft screws of the landing gear. If there are, replace
the washers under the screws.

at the bottom of the center frame or on the Lightbridge
2 Air System for any bending or damage. Ensure that
they are securely connected. (Note: Attach or detach
the cable in the direction aligned to the connector pin
to avoid damage.)
2. Check the remote controller antennas for damage.
5. Check the shaft screws of the landing gear. If they
are loose, apply high strength threadlocker and then
tighten the screws. It is recommended to afx the
screws with 0.45±0.05 N∙m torque.
