Our vertical starboard thruster on BR2 suddenly stops working after some minutes of use. It makes an alarm and a red led shows up on the ESC (see the not great picture below…). It has happened 3-4 times recently and is functional again after disconnecting and powering up.
We were not able to identify what causes it precisely, but it seems to happen with high gain/ heavy thruster use…
it had a red light constantly on and beeped with a siren sound until we disconnected the power.
likely “repeating beeps 1,1,3,3” from the fault description.
