FAQ

Software Configuration

  1. Controller can’t connect to the Assistant software. a. Check if the Driver and Assistant software are installed successfully.
    b. Check if the cable connecting the controller to the PC is connected correctly (for communication upgrades, please connect the cable to the USB port on the LED module). c. Check if the controller has power. d. Replace the USB cable or try another USB port on the computer.

  2. After executing the CSC, the motors don’t power on. a. Make sure the CSC is being performed correctly.
    b. Please connect to the Assistant software or the app and check the status of the main controller. If there’s an issue, you may be able to fix it by following prompts in the Assistant or App.
    c. Please check if the Command Stick Calibration channel sliders in the Assistant software are working normally and if the direction of the channels has been reversed.
    d. Check if the ESCs are working normally and if there are any compatibility problems.
    e. Check if the remote controller is connected to the aircraft correctly.

  3. After takeoff, the aircraft rolls over. a. Check if the controller is oriented correctly.
    b. Make sure the IMU is oriented correctly (check if the corresponding assistant orientation settings are set as intended).
    c. Check if the motors are rotating normally and the propellers are mounted on the proper motors.
    d. Check if each ESC signal cable corresponds to their respective controller cables.
    e. Check if the correct type of the aircraft is selected.
    f. Calibrate ESC throttle range (for third party ESCs).

  4. The aircraft drifts when changing direction. a. Observe how the aircraft self-balances.
    b. Set the GPS relative center of gravity (XYZ value) correctly.
    c. Check if the motors and propellers are aligned horizontally.

  5. The Assistant software can’t be exited after entering SD card read mode. Please reboot the controller.

Hardware Configuration

  1. What kinds of ESC does A3 controller unit support?
    Standard ESCs, 1520μs central position, 400Hz.

  2. Should the red third party ESC cable be disconnected? If the ESC has a BEC, the red cable should be disconnected from the ESC.

  3. How far away can the IMU module be installed from the center of gravity?
    Mount it as close to the center of gravity as possible. Please keep it away from other electronic equipment, such as the GPS module, receiver, and ESCs.

  4. Can the A3 controller’s CAN 1 port be interchanged with a CAN 2 port?
    No, CAN1 ports support the A3 and DJI devices. CAN2 ports are the reserved port. In the future, CAN 1 will be supported by the SDK.

  5. Can the A3 support Lightbridge 1 or FPV devices?
    It doesn’t support Lightbridge 1. When receiving FPV video signal, it can only display image information and not iOSD information.

  6. Does the A3 controller unit have an IOSD?
    The A3 has a built-in iOSD. Lightbridge 2 can display iOSD parameters in real-time.

  7. How can one use DJI’s intelligent flight modes with an A3 controller?
    When using Lightbridge 2, use the DJI GO app to use Waypoints, Course Lock, Home Lock, and Point of Interest.

  8. Does the simulator in A3 Assistant software support third party remote controllers?
    S-BUS protocol based remote controllers are supported.

  9. Does the A3 support PPM receivers?
    No.

  10. Does an A3 used with Lightbridge 2 support the third-party remote control of the gimbal system?
    Yes.

  11. What gimbal does the A3 support?
    Zenmuse Z15 A7/GH4/5D III/BMPCC/XT/X3/X5/X5R gimbal

Others

  1. What does the A3’s iESC interface do?
    It connects DJI Intelligent ESCs for upgrading.

  2. Does the A3 support SDKs?
    It supports the Mobile SDK and Onboard SDK.

  3. What are the advantages of the A3’s RTK GPS?
    High accuracy (vertical: ± 0.03m, horizontal accuracy: ± 0.02m), magnetic interference protection, and provision of accurate flight course data.

  4. Can the A3 fly in low temperature conditions? What is the recommended operation temperature range?
    -10 ºC to 45 ºC.

  5. When using an S900 with an A3 controller, what is the maximum wind speed the aircraft can withstand?
    10M/S.

  6. How can one identify whether the redundant components are functioning abnormally?
    The redundant GPS and IMU have LED status indicators. When the indicator is green or blue, the system is working normally. When the indicator is red, the system is working abnormally. Please connect Assistant software or follow App prompt to find out what’s wrong.
