    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!

    @jake_eizy , I ran a quick model to predict the currents and ESC loss for the 12x6 prop. our database did not have the exact model for this prop, so there was a predicted model and an actual modal published by APC. I hope this helps. I can also provide some more details on best practices for testing new motors / props to reduce the chance of a failure while bench testing. I may be able to put that together into updated test scripts that we already have. Alex [image: 1793824122065-3110_10x5_15x6_prop_compare.png]

For your schematic, these items will ensure a speedy and seamless review: Searchable PDF All items annotated and page numbers correct Off page references if multi-page Caps and R's should have their ratings visible (voltages, power, values) A simple block diagram to help me understand what you are trying to do.

    Hi @gerhold-ten-voorde Yes, you are correct. Pin 56 is the signal "FORCE_USB_BOOT". It is default weakly pulled down by the SoC. To enter eDL/QDL mode, this switch connects a 2-2.2K pullup to VREG_S4A_1P8 (J3 pin 47). So, on M0154, the default OPEN/OFF position does noting, when ON it enables the pullup. Hope that helps. Thanks! Vinny

    Hi @dakota_ltu Under an NDA we could consider the ESC. However, even under NDA, we cannot share the VOXL 2 Schematics unless the recipient is also a Qualcomm licensee with their own NDA with Qualcomm. If that is still a path with value to you, please use this form: https://www.modalai.com/pages/contact-us

    You might also want to double check the current rating of the power module versus the full load from your setup. A lot of weird reboot or brownout issues end up being power related, especially once extra peripherals get added. Keeping the wiring short and using a stable regulator helps too.
