Hello, I am rebuilding my first drone build after some parts broke on a crash. I currently have everything working fine, except for one motor, which is kind of important. whenever i power it on, it beeps, and then wont spin when i try to arm it. I have tried recalibrating the esc multiple times, but it changed nothing. the only time i have seen the motor spin, was when i was trying to spin it through the motor tab in betaflight, and then rebooted the fc, then the esc beeped once, and the motor spun until i unpluged the battery, which was very strange. I have looked everywhere for someone with the same problem, but with no luck. please help. It is not the motor, esc, or the fc, as i have thouroughly tested them all for bugs, so i am assuming it is some problem with betaflight.
