# ESC issue: rotors not spinning Source: https://forum.modalai.com/topic/4726/esc-issue-rotors-not-spinning Category: General Questions (https://forum.modalai.com/category/2/general-questions) Posted: 2025-09-04 10:21:35 UTC by Federico Wyrwal Replies: 3 · Views: 1001 ## Federico Wyrwal · 2025-09-04 10:21:35 UTC We had an initial successful testing of our brand new starling 2 drone. By the next flight we were unable to arm. After some debugging it was clear the esc is unresponsive. How should we proceed? voxl-esc spin logs: ``` Welcome to Ubuntu 18.04.5 LTS (GNU/Linux 4.19.125 aarch64) * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage * Strictly confined Kubernetes makes edge and IoT secure.

When you power on your Starling 2, do you see blue lights blinking on the ESC? You can see the description of the expected behavior here : https://docs.modalai.com/voxl-escs/faq/#q-what-is-the-behavior-of-the-four-blue-on-board-leds. In the ESC datasheet (https://docs.modalai.com/voxl-mini-esc-datasheet/) you can see which side the LEDs are located and one of them is labeled, you should be able to spot the other three next to the each MCU. Do you hear a tone that the ESC typically makes (using motors) when the power is applied? Please check the integrity of the UART cable that connects the ESC to VOXL2. Alex ## Reply by Federico Wyrwal · 2025-09-08 16:30:31 UTC (in reply to Alex Kushleyev) @Alex-Kushleyev The drone was untouched between the first and the next flight. To me the ESC looks clean and I detached and reattached the UART cable. The 4 leds on the ESC first flash at high frequency then the come the sounds, then those leds flash another 4 times then they remain off. I see the same behavior and sound on our healthy drone. The drone will be sent back for inspection today! Thanks for the reply! ## Reply by Alex Kushleyev (ModalAI staff) · 2025-09-09 00:03:28 UTC (in reply to Federico Wyrwal) @Federico-Wyrwal , thank you for the reply. More debugging would be needed to figure out the root cause and it looks like you already submitted an RMA for the inspection / repair, so we will take care of it. Thank you. Alex
