Structure

Visually inspect the aircraft. Use your hands to feel the propellers, frame arms, arm junctions, and landing gear to verify the condition of each component. Any damaged components should be replaced immediately, even a small crack compromises structural integrity.  

The screws for all the connection structures are securely tightened, especially those for the arm junctions and battery locker.

Make sure that the waterproof rubber grommets/coverings are in place. Water or moisture may cause the drone to short circuit.

There is no blockage in the intake vent of the upper cooling fan.

                        Motors

Double check the propellers. They should show no signs of wear, warping or exterior damage. The propellers should be firm. Any signs of wear the propellers must be replaced IMMEDIATELY.

Rotate the motors to ensure that they rotate smoothly. They should sound smooth and consistent. You can do this check manually.

Propellers are mounted correctly. CCW propellers should be on motors 1 and 3, and CW propellers should be on motors 2 and 4 (The front-facing propeller on the right is motor 1, with motor 2, 3 and 4 arranged in a counter-clockwise order).

Batteries

The battery ports are clean and do not show any wear.

The battery locker is secure and will not come loose during flight.

The exterior of the battery shows no visible damage. If you do see damage do not use the battery as it may cause further issues.

Antennas

All the antennas on the aircraft and the remote controller are tightened firmly. They are positioned in a way to give proper clearance to the propellers of the aircraft.

Gimbal (Payload)

The gimbal appears to be intact and can rotate smoothly on all the three axes.

The lens is clean with no signs of wear or damage.

Radar (Payload)

There is no blockage. The shell of the radar has no damage. The mounting bracket is secure and there is no damage to it.

Remote Controller

The control sticks are centered in neutral position, with no foreign objects such as sand and soil, and can smoothly reach full range of motion in all channels.

The screen on the remote controller is clean and dry with no damage. You can clearly view what you see on the screen.

Damping Plate

The dampeners and gimbal anti-drop rope are not damaged. The damaged plate has no crack or split. The gimbal connector is secure and cannot be rotated in the opposite direction after the gimbal is installed.

Infrared Sensing and Vision Systems

There is no blockage in the working range of the infrared sensing and vision systems and auxiliary lights especially when using a non-DJI payload or accessory.

Check the lens or glass of the infrared sensing and vision systems and auxiliary lights.

Clean the lens with a dust-free or soft microfiber cloth. Make sure the lens cap has been removed and the lens is free of any debris or damage.

Essentials

 Remote Controller

Confirm the control stick mode (Mode 1/2/3) and check in the control stick calibration page in the app if the proportion of the control level is correct.

The remote controller has sufficient power and the battery is firmly installed.

Confirm that the channel used is automatic or custom, and then choose the operation frequency and channel according to the signal-to-noise ratio.

 Battery

All batteries, including Intelligent Flight Batteries and remote controller batteries, are fully charged.

It is recommended to charge and discharge the battery by following the standard instructions before flight if the battery is stored for a period longer than one month. You can view these instructions in our in-depth Maintenance Guide

The Intelligent Flight Batteries are firmly installed.

Check the battery level and voltage of each battery cell in the battery page in the app to make sure they are normal.

 Flight Parameters Configuration

The Failsafe action of the aircraft is what fits your mission needs. For example, the aircraft will land as a failsafe within 50m of the Home Point, and it will hover as a failsafe when it is within 200m from the Home Point.

The flight mode switch is set up correctly.

RTH altitude, height limits and distance limits and obstacle sensing function are set up correctly.

Module Auto-Check

View the module auto-check information on top of the screen in the app to check if there is any error prompt.

                        GNSS Positioning

There are at least 7 satellites, and the aircraft works in P-mode. Enable RTK function, select the correct base station and channel, and make sure that RTK positioning is in use.

 Sensors

Data on each IMU is shown in the app. IMU calibration can be performed successfully.
Data on each compass is shown in the app. The heading of the compass matches the physical one, and the needle is stable.

Compass calibration is performed successfully.

The Vision System in all directions is enabled and there is no error prompt.

Top and Bottom Cooling Fans

Touch the shell of the cooling fans or listen carefully to check if the cooling fans work normally without noise.

 Firmware Consistency

Connect the remote controller to the internet, then launch the app. Make sure that the app and the firmware versions of the aircraft, remote controller, payloads, and batteries match.

Double check all the Intelligent batteries by testing them briefly in the aircraft. If the firmware is not up to date the battery will not allow you to fly.

 Motor (Spinning)

Link the remote controller and aircraft, make sure the FPV camera display in the app works normally, and then perform Combination Stick Command to start the motors in a safe indoor area to make the motors spin at an idle speed. Then test the following. NOTE: Stay away from the spinning motors and propellers to avoid injuries during the test.

The motors start without noise. Check the app to see if there is an error prompt. If there is, do not fly.

At the beginning when the motors start or the end when the motors stop, observe the motors to make sure that motors 1 and 3 rotate counterclockwise while motors 2 and 4 rotate clockwise.

Essentials

Is satellite count more than 10? DJI requires at least 10 satellites. Is there sufficient light outside? Press record.

In P-mode, perform CSC (cross stick command) to make the motors spin at an idle speed on the ground. Push the control sticks in each direction lightly to test. Then push the throttle stick down to the bottom until the motors stop.

In P-mode, perform CSC to make the motors spin at an idle speed on the ground. Observe to check if the aircraft shakes. Then push the throttle stick down to the bottom until the motors stop.

In P-mode, take off and hover at a height of 5 meters for 1 minute. Check to see if the aircraft horizontal drift is no more than 1 meter and the height drift is no more than 0.5 meters. Check the shake of the aircraft, battery status, sound of the motors and propellers.

Push the sticks in each direction. Be gentle. Make sure the aircraft responds appropriately and that the sticks work.

Gradually increase the movement of the control sticks to observe the altitude response and the shake of the aircraft when braking.

Set height and distance limits. Test to see whether the drone obeys the limits or not.

In P-mode, fly the aircraft more than 20 meters away from the Home Point at an altitude less than the preset RTH altitude. Initial RTH using the RTH button on the remote controller to test if the aircraft can perform ascending, cruising, landing in order and the landing position has an error no more than 1 meter from the Home Point.

Stop video recording after landing

After landing, please check that the aircraft remains undamaged. Check the propellers and components for damage. If you see any damage, please contact us or DJI.

Ensure that the temperature and sound of the motor is normal.
