Please can you you confirm you checked everything before soldering (I could not see from your video if you have soldered anything yet or not)
How do I test my new Flight Controller? (and why it’s important)
That beep sequence indicates that your ESC is not picking up a valid signal from your FC. When it comes to your FC not receiving a valid signal from your ESC is usually caused by one of these issues, so please can you double check:
1 - Make sure you have the correct firmware target flashed on your FC, see - How to install/Flash Betaflight Firmware (GUI or DFU Mode). You should be able to get the correct firmware target from
2 - Make sure your ESC is connected correctly to your FC, just because the two cables fit together, does not automatically mean they are connected the right way. You just need to make sure that each of the ESC pads, S1, S2, S3, S$, are correctly connected to the motor outputs on the FC etc…
Please let me know how you get on so we can try to help further.
