    Hello. I purchased a Starling 2 Max development drone and when attempting a first flight test I discovered that one of the batteries arrived entirely dead. I was curious if there was a way to receive replacements, and if this falls within replacement territory. I contacted the support email and was directed here. I can provide more information if needed.

  • Do you have a great idea for our products you would like to see implemented?

    Hello everyone, I am looking for some expert advice on a VOXL 2 companion computer setup for a long-range platform. I have two main integration challenges: Challenge A: VIO at Higher Altitudes To solve the motion blur and pixel density issues at higher altitudes, I am planning a 6-camera configuration. I want to use 4 downward-facing sensors (2 daylight + 2 IR) equipped with narrow-angle lenses, alongside 2 standard wide-angle sensors (front and rear). Could you advise on the best supported sensors (e.g., IMX series) for this? Has anyone successfully tuned the voxl-qvio-server for narrow-angle lenses, and what were the altitude limits you achieved? Challenge B: LAN Integration & WireGuard The payload data flow will be: External RTSP Camera -> Ethernet -> VOXL 2 (WireGuard encryption) -> Ethernet -> Digital RX. Because VOXL 2 lacks multiple LAN ports, I will need a miniature industrial Ethernet switch. Does ModalAI have any tested hardware recommendations for this? Furthermore, what is the best practice for routing this VPN traffic through the VOXL 2 Ubuntu environment without bottlenecking the CPU? We are currently evaluating the VOXL 2 for a broader fleet deployment and want to ensure the ecosystem can support this custom optics requirement. Any feedback on off-the-shelf solutions or standard configurations for this use case would be greatly appreciated. Thank you!

    @nl_vdi , if you log into developer.modalai.com, you will see the CAD models. the latest model we have is: D0012-4-V3-C28-M36-T7-K0-Starling2-Max-V3-20260317.step [image: 1781036132877-376bf0dd-494a-4bf1-8d92-1b2d91afb83d-image.png]

    It is likely there were not stable visual features on takeoff. A field of grass is not that great for visual feature tracking. You could try putting something in front of the drone on the ground for it to look at and see if that helps

    It sounds like you are putting the drone into offboard mode, with the offboard mode set to "figure_eight". https://docs.modalai.com/voxl-vision-px4-other-features/ You shouldn't need to be in offboard mode to use the apriltag relocalization, see here: https://docs.modalai.com/voxl-vision-px4-apriltag-relocalization/

    Hi @kiprock , The motor test commands I've used were from the MAVLink shell, but using the pwm test command: https://dev.px4.io/master/en/middleware/modules_command.html#pwm I've seen similar issues when trying to use the built in QGC PWM calibration feature... Since the Flight Core v1 can't be powered over USB (an artifact of sharing the 5VDC rail with VOXL when paired together and the fact that 500mA isn't enough to juice VOXL), it requires the python util that you linked above.

    Hi @Arrowtec , I've seen this myself before. In my case the device would then show up after running sudo fastboot devices and I could proceed after trying again. If it's not showing up with either sudo fastboot devices or adb devices it would likely need the Debug board which allows you to force it to boot into fastboot....

    The Flight Deck has the two main components (VOXL and FlightCore). They share a 5VDC rail that is fed by the Power Module on the M500. The FlightCore portion of the board is a little STM32 microprocessor running PX4. PX4 reads that 5VDC from an ADC. Depending on your toolset, it could be easy to probe that voltage: https://docs.modalai.com/voxl-flight-datasheet-connectors/#j1013---5v-dc-power-input-i2c3-to-power-cable-apm When you did the manual flight you had no issues?

    @James-Strawson got it. My test s/w version is volx-vision-px4 0.3.4 and has a same problem, am I right? Okay, I’ll proceed test VOA using 0.2.0 version before releasing new version s/w. Can I know release date for new version? Thanks,

    I assume you are using the master version of voxl-vision-px4. Since the is_cam_master is false, is voxl-vision-px4 still running? vvpx4 would be the camera master in that case Can you check what TRACKING_CAM_ID is? 'echo $TRACKING_CAM_ID' If you have high-res, stereo and tracking plugged in TRACKING_CAM_ID should be 1 which matches what you have in the launch file

    @gauravshukla914 , I for the first time got the "avionics power low" message! I turned off the ADCs on FlightCore for a test and got this error. PX4 monitors the 5VDC rail (and 3.3VDC), and this makes sense now, as the output of that power module was lower than expected. Anyhow, I remembered this post so figured I'd put some details here while I saw it

    Hi @abdullah , Was the PX4 FW version changed at any point? We have seen some performance issues with PX4 1.11 and the position controller. I see in your logs you have v1.11.2 going. Is there anyway to load the ModalAI 1.10 FW as a data point and see if the flight performance changes? https://docs.modalai.com/flight-core-firmware/#px4-v110 Thanks!

    Thanks for this detailed response! This would be good information to put in the technical documentation when searching in google for "modalai flight core connections for magnetometer" there wasn't much information on how to setup a magnetometer with the flight core. I was able to setup the the RM3100 by using J13.[1,2] for 3.3 VCC and GND and the J10.[4,5] for the I2C protocol. This allowed me to set SYS_HAS_MAG=1 in PX4 and successfully calibrate the compass
