Help! What is this beeping noise? Is it related to what my transmitter is telling me in the background?

That sounds like the ESC isn’t receiving a signal from your receiver. Show us your wiring between your ESC and receiver.

My wiring is defiantly fine, everything on the plane is functional. It just randomly did this suddenly and I don’t know why.

Well… that’s the sound that an ESC makes when it isn’t getting a PWM signal from the receiver. 🤷‍♂️ Wiring broken, bad receiver, bad receiver settings maybe (set to PPM/SBus output instead of PWM), plugged into the wrong port, maybe set your receiver to TAER vs AETR

If you have a servo tester, you could connect that to the ESC instead of the receiver. If that works, then it’s something wrong with the receiver or the connection to the receiver.

I agree with @Foamforce, the ESC is not getting a pwm signal.

I'm not sure of the cause of the signal loss. Are you absolutely sure everything on the plane is functional now.

My guess, you have an ELRS rx & something is not allowing a correct bind.
