@Eric-Katzfey No, the propellers are well positioned (that was the first thing i checked). I compared the drone with another starling 2 drone during arming, the drone not flying (the one i am trying to get fixed) makes more noise, as if the propellers are spinning with higher power while the other drone (the good one) doesnt make as much noise. Also, a point to note, the drone has been working fine since may 2025, up until two weeks ago, so I don't know what might have caused this.

@Eric-Katzfey HI, I have attached a flight log.

Thanks!

@Zachary-Lowell-0 Hi, let me explain what i meant by hovering mode. There is a 3-way toggle switch beside the kill switch in the transmitter (toggling down switches to position mode, toggling up switches to the autonomous mode, while toggling to the middle maintains the drone flight positioning. I have another drone that when the button is switched to the middle, it maintains the drone position (thats what i meant by hover mode). My other starling 2 drones maintains their positions when the switch is toggled to the middle position, but this particular starling 2 drone doesnt.

Hi,

My starling 2 drone was working perfectly up until two weeks ago, I wasn't in the lab last week (so i cant say if anyone tampered with it or not), but right now my propeller spins, but the drone isn't moving from the ground (it sounds like its forcefully trying to lift). Can you help with what might be the cause?

Thanks,
Taiwo

Hi Support,

Kindly assist. I have a starling 2 drone that keeps moving towards the left, sometimes right and sometimes it keeps moving up when i switch the controller to hover mode (for a very few time, it hovered at a spot), but most times, it keeps moving. What could be wrong ? It has been like this ever since it was purchased. Kindly put me through what i need to do to run diagnostics.

Thanks,
Taiwo

@taiwohazeez @Zachary-Lowell-0 , please i am still waiting for a response, an advice on how to go about Apriltag detection on starling 2 would be greatly appreciated.

Thanks

@Zachary-Lowell-0 yes, i copied that directly from the terminal after running this command voxl-inspect-detections -a tag_detections.

Thanks,
Taiwo

Hello support,
I have an issue detecting apriltags with my voxl2 (starling 2), I looked at the documentation online to see how it works.
I ran voxl-tag-detector, and i got this

Then on another terminal, i ran voxl-inspect-detections -a tag_detections, but i keep getting unknown, can you help with what i might be doing wrong.

Meanwhile, I have ros2 run voxl_mpa_to_ros2 voxl_mpa_to_ros2_node running.

KIndly assist @tom @teddy-zaremba
