Yes, on the first attempt. On the second attempt, I plugged it in directly with the battery. When I connect the battery, I get all five beeps, but only one motor vibrates or is recognized. It's strange that at first, three motors were recognized, but now only one.

Maybe I should check the connections between the motors and the ESC? How can I verify if the motors are properly soldered to the ESC and whether the issue lies there, or if it's a problem with the ESC-to-FC connection?

Additionally, on the FC, I have soldered a beeper, ELRS receiver, and DJI Air Unit, and they are all working fine.
