Caution

The sensor and attitude data must be normal before takeoff; otherwise, the aircraft may crash. For detailed inspection and calibration instructions, refer to the calibration section in the power-on and commissioning procedure.

Warning

Remote controller check: Before using the UAV, place the SA/SB/SC/SD switches on the remote controller in their uppermost positions. Transportation may have moved them to other modes. Before use, review the relevant remote controller operation section and familiarize yourself with the remote controller channel settings.

1. Connect the Remote Controller

The red box identifies the QE3 remote controller power button. To power on the controller, briefly press and then press and hold the button. The brand logo and system loading screen will appear, followed by the default desktop or home screen. Use the same method to power it off. 2. Install the Battery

The battery is installed on the bottom of the UAV. Press the battery latch and secure the battery firmly to the aircraft to prevent it from loosening or falling out.

3. Power On the UAV

The green box identifies the rear power button. Briefly press the button for 0.5 s to power on the UAV. Use the same method to power it off. Do not press and hold the button, as doing so may cause the aircraft to power on and immediately off, or power off and immediately back on. image.png 4. Configure Ethernet

On the remote controller, go to Settings > Network & Internet > Ethernet > Ethernet Configuration to view and configure the current IP address.

  • Default static IP: 192.168.1.123

  • Subnet mask: 255.255.255.0

  • Gateway address: 192.168.1.1

5. Connect QGC

  • After the Ethernet configuration is complete, tap QGC on the QE3 remote controller to open it. Tap Application Settings, tap Comm Links, and configure the connection. image.png

  • Configure the name, port, UDP, and IP address. (The name can be chosen freely. Select UDP. Use port 58080, which was configured when pairing the video transmission system, and use IP address 192.168.1.123. For detailed configuration instructions, refer to the relevant remote controller operation section.)

  • After completing the settings, tap Connect and wait for QGC to connect successfully.

6. Verify Positioning and Performance

In the web console (192.168.1.88:18080), open the positioning status page and verify that pose and confidence data are being output normally. Confirm that the system is in "vision + radar" fusion mode and that the positioning result neither drifts nor diverges.

Hold the entire airframe and move it a short distance. Observe whether the trajectory displayed on the web interface converges and remains accurate, with no signs of divergence.

Coordinate Frame Synchronization Test:

QGC interface: On the flight controller's MAVLink inspection interface, open the LOCAL_POSTION_END screen and observe the X\Y\Z-axis data. Using the aircraft's heading at the origin (the algorithm startup position) as the reference, moving forward is positive X, moving backward is negative X, moving right is positive Y, moving left is negative Y, moving up is negative Z, and moving down is positive Z.

On the flight controller's MAVLink inspection interface, open the ATTITUDE screen and observe the roll\pitch\yaw attitude data. Using the aircraft's level attitude at the origin as the reference, pitching the nose down is negative pitch, pitching the nose up is positive pitch, rolling down to the right is positive roll, rolling down to the left is negative roll, yawing left decreases yaw (the attitude indicator value decreases), and yawing right increases yaw (the attitude indicator value increases). image.png

7. Install the Propellers

Warning

Before assembly, clearly identify the nose and tail directions of the UAV, verify the actual rotation direction of the motor on each arm, strictly match each propeller to the corresponding rotation direction, and install each propeller with the correct side facing up. Incorrectly identifying the nose or tail, using an incorrect motor rotation direction, mixing up propeller rotation directions, or installing a propeller upside down will prevent the aircraft from generating lift properly and may cause uncontrolled spinning in the air, resulting in a crash, equipment damage, or personal injury.
  • Confirm the aircraft's nose direction;

  • In QGC, click the controls highlighted by the white box in sequence as shown to check each motor's rotation direction and ensure that every motor rotates in the correct direction; image.png

  • Install the propellers: The side with the raised markings is the windward surface. Match the windward surface of each propeller to the corresponding motor rotation direction, and install the propeller on the motor with the markings facing upward. Install a counterclockwise propeller on a counterclockwise motor and a clockwise propeller on a clockwise motor.

Motor Rotation Directions:

As shown, motors 1 and 2 rotate counterclockwise, and motors 3 and 4 rotate clockwise. image.png Counterclockwise Propellers: img_v3_0214a_95878479-f9ad-4faf-b97c-24d918dc087g.png Clockwise Propellers: image.png Installation Orientation: image.png

8. Install the Propeller Guards

  • Identify the orientation of each propeller guard: The side with the greater curvature faces the aircraft's nose, and the side with the smaller curvature faces the aircraft's tail;

  • Assemble the supports: When installing a propeller guard, position the gray carbon-fiber support above the black retaining clip. image.png

9. Calibrate the Sensors

Calibrate the gyroscope, accelerometer, and level horizon in sequence. (Select a level surface during calibration. The compass does not need to be calibrated.) img_v3_02137_a0247645-cde5-48dc-9312-10001243150g.png

10. Perform the Preflight Checks

  • Place the aircraft indoors in a well-lit area and ensure that there are no surrounding obstacles. The pilot must stand 5 meters from the aircraft and face its tail.

  • Check the battery level and install the battery.

  • Check that the aircraft's exterior is intact, with no obvious collision damage or abnormalities.

  • Power on the remote controller, ensure that all remote controller switches are in their default positions, and power on the aircraft. Check that the signal strength indicator in the remote controller's status bar shows that it is paired with the aircraft.

  • Connect to the QGC ground station and enter the flight screen. Check the satellite count, flight mode, battery level, remote controller settings, flight mode settings, and other flight-related parameters. Ensure that the parameter settings and calibrations meet your requirements to maintain flight safety.

  • If multiple aircraft are being tested simultaneously, divide the area into separate flight zones to prevent mid-air collisions and serious safety accidents.

11. Remote Controller Controls

(1 is Channel 5, 2 is Channel 6, and 3 is Channel 7. Channels 5, 6, and 7 are all three-position switches. To lock the propellers with Channel 7, move the switch toward the screen.)

Channel 6: The first position is Position mode. Use this switch to change the flight mode. Switch back to Position mode; the aircraft can be armed normally if QGC reports no errors.

Channel 5: UAV arm/disarm switch. The uppermost first position disarms the UAV, and the lowermost third position arms it. After arming, move the control stick to begin flight. (Move the stick slowly.)

Channel 7: The uppermost first position disables the emergency propeller lock, and the lowermost third position activates the emergency propeller lock. This provides one-switch propeller locking in an emergency. (Use it if the UAV becomes uncontrollable or behaves abnormally.)

12. Perform the Final Flight

The first test flight may be conducted only after all preceding steps have been checked and confirmed to be correct.

FlyCore supports AI control of the UAV for secondary development. For details, see the Integration Guide for Developing the FlyCore WEB Ground Station with AI.
