Assuming your Stinger SKU contains an ExpressLRS modem (ModalAI M0184 Gemini RX), you will want to follow the ExpressLRS Binding procedures. Firstly, to put the receiver into "binding" mode, you'll want to either press the bind button for at least 1.5 seconds, and you must do this at least a few seconds after the battery has been inserted (or anytime later). You can also put the receiver into binding mode by powering on and off the Stinger 3 times quickly, though this can be unreliable. You will also need to make sure your transmitter is compatible with the receiver, and in a compatible mode. The M0184 by default comes with firmware based on ELRS 3, so you will need to verify that your GX12's internal ExpressLRS firmware is also on major version 3, otherwise you will need to downgrade to V3. Furthermore, the GX12 comes with a dual-band transmitter which supports 2.4GHz and 915MHz operation. To work with the M0184 you must make sure the selected "RF Band" parameter is "915 MHz", and the packet rate is 50 Hz 100 Hz, or 200 Hz. Other packet rates are not supported on the older modem in the M0184.

@Vinny Understood, but this affects our schematic design. We simply need to understand the purpose of pin 25, “3.8V Primary ‘Phone’ Power (mimics nominal 1S),” and how it should be connected. This information is not provided in the M0161 datasheet.

On the Wi-Fi questions: The -M36 option ships with an Alfa Network AWUS036EACS (802.11ac AC600, dual band 2.4/5 GHz, Realtek chipset, made in Taiwan). It is listed on the Starling 2 Max datasheet. Yes, you can use a different USB adapter, as long as the VOXL 2 kernel has a driver for its chipset. You cannot install arbitrary vendor drivers without rebuilding kernel modules, so pick an adapter based on one of the Realtek chipsets we support: RTL8812AU or RTL8821CU / RTL8811CU. The adapters we have tested are listed on the VOXL 2 WiFi Setup page. If you find a Japan-certified (Giteki) adapter with one of those chipsets, it should work with voxl-wifi in both Station and SoftAP mode. If you cannot find a certified adapter with a supported chipset, another option is a USB-to-Ethernet adapter on VOXL 2 connected to a small Japan-certified Wi-Fi bridge or travel router on the drone. VOXL 2 only sees Ethernet, so there are no driver constraints. In SoftAP mode the default hostapd country code is US. For use in Japan, set country_code=JP in /data/misc/wifi/hostapd.conf after running voxl-wifi so the radio uses Japanese channel and power rules.

@qqa , we have document how to achieve folder-level encryption on VOXL2 here : https://docs.modalai.com/enabling-file-encryption/ . Please let us know if you have any other questions.

Sorry @senja for the delays, this post did not get flagged for me. Yes, they install on different sides of the VOXL 2 board as shown here: https://docs.modalai.com/voxl2-connectors/#connector-callouts [image: 1792693889198-9a619597-c0ad-460a-b43a-c0689c8a0aab-image.jpeg] https://docs.modalai.com/M0226/#overview [image: 1792693659205-3064b401-56ca-4e7d-973c-0fe9c3ebe5cc-image.jpeg] https://docs.modalai.com/m0062-datasheet/#connector-callouts [image: 1792693766032-bc42a15b-8021-47f4-a9b6-534603ed8399-image.jpeg]

Thanks Tom and Eric, finally resolved this, it ended up being a power supply issue. The unit we used to typically run it on the bench seemingly browned out somewhere in the flashing procedure.

Hello. Can a Starling 2 drone autonomously fly while flying over the pipe inside a sewer? The drone must fly autonomously in a dark place to inspect cracks or internal conditions while flying along the water pipe. I'm not sure if this feature can run on Starling, so I'm asking for help!

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!

Hi @alex-z-1 Here is the STEP for the front tracking mount: https://storage.googleapis.com/modalai_public/modal_drawings/D0013_Front Tracking Mount.step Note this is the V1 plastic. The V1 Stinger has been EOL for some time, so this came out of archived CAD rather than a current release. One observation from your photos: the film is still on the battery pad. That likely contributed to the battery stop breaking, though it would not have saved the camera housing. Let us know if this helps!
