@alex-kushleyev @eric-katzfey Apologies for the direct mention — I hope you don't mind. I posted this question set about two weeks ago (and a related product question three weeks ago), but haven't heard back yet. We are preparing to purchase a Starling 2 Max (C29, with the PMD ToF) as an evaluation unit for an indoor GPS-denied inspection project, and just three answers would unblock our decision: Can VOXL SLAM / VOA (with the dense PMD ToF on the C29 configuration) reliably handle very narrow corridors — around 300 mm width? Any references to pipe/industrial inspection use cases in similar tight spaces would be very helpful. For repeated missions in the same indoor space, is voxl-mapper + AprilTag re-localization the recommended pattern to bound Open-VINS drift (no loop closure)? What is the practical minimum illumination for reliable VIO with the tracking cameras — and do you recommend onboard IR/LED illumination for dim industrial interiors? Even brief pointers to relevant docs would be greatly appreciated. Thank you for the great platform and documentation!

Hi @adam These claims remain true. We are exploring some items in the future for individual certification to ease downstream efforts by integrators, but as of today, the efforts still largely fall on the end-product integrator (which is unavoidable no matter what certifications we employ) and we can help where needed if any requests are specific and actionable.

Sorry to hear that. https://www.modalai.com/pages/rma You can provide a link to this post when you submit it.

Hi @Julian , Thank you for the detailed report. It does look like there is a missing (or broken? hard to see) magnet in the motor, in which case the motor will not work properly and should be replaced. No further testing is needed, as this is most likely a manufacturing defect of the motor or a result of an impact. If you believe that the motor was defective when you received the product, you should request a free replacement motor (submit an RMA form) . If the motor was damaged while testing, you can purchase a new motor. The Starling 2 Max replacement parts can be found here : https://www.modalai.com/products/starling-2-max-replacement-parts (however i don't see just motors without a frame + motors kit, will double check..)

Hello @RoyAzriel , If you are going to be experimenting with adding different sensors (Lidar), then Starling 2 Max is definitely going to offer more flexibility due to the larger size and longer flight time. You should consider the dimensions of the tunnel and make sure that the drone will easily fit. I have no idea how small the cross section of the tunnel is, but if it is very small (just several times larger than the diameter of the drone), then it would be very difficult to fly due to air circulating in a small space. What Lidar are you considering adding and what is its weight and communication interface? The illumination will depend on your specific application, depending on how far you need to see. You should be able to add standard LED lights. if you need to control the LED intensity, you would need to get an LED with built in adjustable LED driver and optionally control it using PWM output feature on the ESC. Are you going to develop your own mapping and navigation stack for this application? Alex

@minhthinh Documentation for the original VOXL Flight can be found here. The guide will link back to the original VOXL and the original Flight Core as those are the boards it was built around. You can also refer to the release notes of the previous sdks to see what was available in the specific release that you are using

I fix this issue. switch the Pin1 & Pin4 of MCBL-00010 cable is OK

@kabumei Hello, my name is Naoki, I am keen on this project, could you send me a detail to major.gits501@gmail.com?

@tom Thank you! Submitted the RMA today (22-NOV-2025). Did not get any number or anything, but the following message: [image: 1763832180096-a25e2aa8-af17-4b82-8b20-c78ef379e805-image.png]

@Maxwell-Schaefer Thank you! I was able to set the model match to off using the controller screen.

@mkriesel , just to confirm, does this test work (run) on other voxl2 boards for you?

@marian Unfortunately VOXL1 has really been phased out but this board has the "fastboot" button on it and should work for you: https://www.modalai.com/collections/expansion-board/products/voxl-microhard-modem-usb-hub

@adiprin1 Can you please start a new forum topic for this? And please include information about the device that you are looking to attach? Thanks!

Hi @Martin-Lukac Good catch on the pin swap. The Table is correct, with Pin 6 = GND. The one thing I was wondering is related to this comment: " I can power the ESC and the FCv2 separately." That is not necessarily a good thing, and likely to lead to problems if you are powered up or down at different times. If one output (TX) is driving an unpowered input (RX), it could put the HW in a bad state. Please make sure to have them synced for ON and OFF. Thanks.

@gestrada1150 I think it should come with gps denied navigation configuration out of the box, you can verify and set it up yourself here: https://docs.modalai.com/flying-with-vio/

@Steven-Girouard Are you using PX4? ArduPilot? You could run that directly on the VOXL 2 mini depending on what your IO needs are.

@ravi The documentation has been updated. If you are running a recent release from us then you will be using the ICP-20100 barometer. The BMP388 will not be started.
