    I have recently started working with the VOXL2 – Starling 2 Max development drone, and I have several questions and observations from my initial experience:

    VIO / Mapper Drift
    While exploring the system through the Portal and reviewing the documentation, I noticed that in the Mapper and VIO tabs the estimated position sometimes drifts. This behavior was reflected during my first flight, where the vehicle drifted along the Y and Z axes, eventually leading to a crash.

    MAVLink Position Messages
    In QGroundControl’s MAVLink Inspector, the message POSITION_TARGET_LOCAL_NED reports zero values for x, y, z, vx, and vy, while LOCAL_POSITION_NED reports the expected values.
    I verified that both qvio-server and OpenVINS outputs appear to be working correctly, which makes this behavior confusing.

    Helper Parameters for Indoor Flight
    I am currently trying to fly the drone indoors and configured the PX4 parameters according to the following helper file:
    helper params

    This configuration requires disabling both GPS and magnetometer inputs. However, during flight I still receive the warning “height estimate not stable”, which I initially assumed was related to GPS or magnetometer availability.

    Failsafe Events
    From the flight logs, I noticed:

    A failsafe being triggered at the very beginning of the flight (around home position initialization).

    Another failsafe shortly before the crash, with the message:
    “Preflight fail: attitude failure (roll)”

    Based on these observations, I have a few follow-up questions:

    Does the Starling 2 Max require a full calibration procedure from the beginning?
    I have already calibrated the level horizon, accelerometer, and gyroscopes, but I have not calibrated the magnetometer, since it is not being used for indoor flight.

    Does the Starling 2 Max include VOA (Vision-Based Obstacle Avoidance) hardware by default?

    I am also encountering an issue with voxl-dfs-server, where the service is enabled but not running.

        @Saleh-Ibrahim the drones come pre-configured for VIO and are flight tested in VIO mode prior to shipping.

        To troubleshoot VIO, please start here: https://docs.modalai.com/voxl-open-vins-server/#troubleshooting

        VOA does not ship enabled by default
