Hi @JoonaR, Yes, the Starling 2 drones are shipped with the lepton adapter (M0187), but Lepton sensor itself is not included. https://docs.modalai.com/M0187/ Alex [image: 1768357442694-0cb77fc6-242f-4477-a15d-3c89f43d8f69-image.png]

@colombe-ai You can find the batteries here: https://www.modalai.com/products/m10000538 Any 2S LiIon hobby charger will work. Something like this is all you need: https://www.amazon.com/ISDT-608PD-Battery-Charger-Discharger/dp/B0CM9BFQSX Handheld transmitter depends on the configuration of the drone. You can order the drone with a pre-bound charger ready to fly from the website. The main debugging cable is a standard USB-C cable

@colombe-ai currently 30 business days is quoted on the website: https://www.modalai.com/products/starling-2-max It typically should ship more quickly than that though, likely 2-3 weeks There is no overnight shipping option as all of the drones are built to order

Hello @HsinSWT , When i see results like this, i would say there is probably 90% chance that the motor is bad. Unfortunately, there is a chance that the ESC is bad as well, and there is no good way to check the ESC without a known good motor (however the ESC failure is unlikely). As I mentioned in the previous post, if you had a milli-ohm meter, you could test the motor winding resistance to confirm whether the motor is good or bad. A tool like that measures resistance with high precision (similar to a regular Ohm meter). However, if you don't have one, it may not be worth buying it.. You will not be able to measure the winding resistance of these motors correctly with a regular Ohm meter. However, you will be able to detect a complete open circuit (which could be the case, maybe worth trying). If testing resistance using a regular Ohm meter, any two connections between the 3 motor phases will read 0 ohm (or close to that). If a wire is broken, then you can detect it. The Starling 2 motor (3000kV) has around 0.360 - 0.370 Ohm phase-to-phase winding resistance. In order to confirm that the ESC is working properly, you could temporarily connect one of the working motors to the ESC Channel 0 and do the same spin test (using voxl-esc tools), just to confirm that the ESC Channel 0 is working fine. In order to fix the issue, you could order a new motor and replace it yourself (will be a lot cheaper): https://www.modalai.com/products/starling-2-replacement-parts?variant=49707605393712 You could also send the whole drone back for repair (https://www.modalai.com/rma) Alex

@colombe-ai , when you flash a voxl2 SDK, there should be an option to set it up from scratch. did you try it? https://docs.modalai.com/voxl-suite/ Alex

@Nitin-Varma-Vegesna Well, that's why I asked you to do the full SDK installation. If you install the SDK and set it up as we do from the factory then it should be working like when you first got it. If it doesn't then that potentially points to some damage caused by the crash and not some configuration change you have made since then.

@Alex-Kushleyev This unit was sent in on RMA 796.

@Muqing-Cao Here you go: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/blob/dev/src/vio_manager.c?ref_type=heads#L450

@Eric-Katzfey I updated to SDK 1.6.0, which fixed the power display issue. I was still getting no valid local position preflight fail, but after I ran apt update && apt upgrade, things seemed to work.

@Jakub-Tvrz said in Starling 2 Max for indoor: We haven't bought anything yet, but we are deciding what will be the best for our warehouse inventory application. Of course, we considered the ToF option. But you still say: "however, it is not... great" - does that mean that Starling 2 is better for our application? Or does Dual vs Triple camera for Visual Inertial Odometry also have an impact? Reply Depends fully on your use case. I will say that PX4's instance of obstacle avoidance is not fantastic, but it is better than nothing. In my opinion I would go w/ the model that has all the bells and whistles in case you need the hardware and decide to develop your own collision avoidance or somethign of that nature.

@jimbow77 , regarding #4, there are four batteries (two sets). #3 - we don't have an option to install FLIR Lepton, but you can purchase it separately (from another vendor) and install it. The adapter is present in Starling 2 Max, so you would just need to install the Lepton sensor into the socket. Alex

@SystemBrute . The problem has been solved.

@Moderator Why is it not plug in play? I found the spot to connect to the board but configuring the SKU based on C29 did not work. Also, the connector seems really short so I am curious how the C29 config looks.

@Karthik-Bharadwaj You'll need to insert this into the unused XT30 connector: https://www.modalai.com/products/mcbl-00109?_pos=1&_sid=cc83b4694&_ss=r 3A is more then enough to power the drone on the bench, just make sure never to spin motors on wall power! (You can damage the drone and will not be able to RMA it) In order to disable arming you'd have to look through the PX4 parameters

@roy-crosthwaite , please submit an RMA form for a replacement : https://www.modalai.com/rma Thank you Alex
