I’ve been experiencing an issue with the T500 ESCs. One of my T500 thrusters works perfectly in the forward direction, but occasionally when commanding it to spin in reverse, it emits a loud beeping noise and loses the ability to spin backwards entirely. The only way to recover it is to command the thruster forward first, then back to reverse. I believe this is an ESC issue since swapping to a different ESC resolved the problem. Has anyone else run into this?
Hi @IvanZheng, welcome to the forum 
Sorry to hear about your issue, and glad you managed to resolve it.
I don’t believe we’ve come across an issue like that before - it’s possible we’ll want to get that faulty ESC back off you to investigate further. If you haven’t already it would be great if you could fill out our product problem form so we can at least register the issue internally, and follow up as relevant
