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.

Could you please clarify the purpose and required connection for pin 25, as this affects our schematic design?

@tom Thank you, Eric and tom. The answers on the RC receiver, failsafe and Wi-Fi were very helpful. We expect to make our purchase decision soon, so I would like to follow up on the remaining points from my last post: Propeller guards: Are official guards or a cage available for the Starling 2 Max? If not, are CAD/STEP files of the frame or arms available? Payload (about 100-300 g): Is there a recommended mounting point? What power output is available (voltage and maximum current)? Roughly what flight time should we expect with 300 g? Lead time: Is "ships within 60 business days" still the current lead time for the C28 / Wi-Fi configuration? The lead time is the most urgent for us, so even a rough answer on that alone would help a lot. Thank you for your support.

@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 @elvis-bicharri OK, it's a big one (~385MB), so please be patient.. but our team got the full Starling 2 Max 3D step file for you. I hear it is the latest, but this is not my domain. [image: 1794024833389-2ee5f241-66dd-4c2a-bed4-46cc6e6dcf00-image-resized.jpeg] Here is the link...https://storage.googleapis.com/modalai_public/modal_drawings/MRB/D0012 Starling 2 Max 11-6-26.STEP We hope this is what you needed. Let us know if we can help for anything else. New posts are always best for a change of topic. Thanks!
