Sometimes one of my motors won't start...

[Jdmagoo]

I did my first maiden over the weekend and have noticed sometimes after I arm the hexa one of the motors won't start, if I disarm then re arm it will. It happens randomly with different motors. Not knowing what the cause is, my concern would be one of the motors stopping in flight. Should I post a log?

ESC32 firmware 1.4.3 r32
Tiger motor MN3110-17
AQ 6.8 r233

Thanks in advance

I got several cheap 800kv 2212 motor from china, I can run them without propeller, but when mounted, they would tried a bit to rotate, but eventually disarmed the esc. I read this post , then up the setting to 1.8v, still no go, should I crank it up even further? Will it cost mechanical damages to the motor? Thank you.

There can be a number of reasons why your motor won't start with prop on it. Did you calibrate the ESC32 for your motor?

Some motors don't work well with the default settings.

I didnt start the calibration process yet, I was thinking maybe I should get the startup setting right first. Maybe someone here will have advice about how to do it properly.

Set up the correct poles,
and increase the MAX_PERIOD to Max
after this, you can set up the START_VOLTAGE to ~2.4V

The number of magnets your motor has is the number of poles your motor has. The default Max Amps is 20 amps and should be lowered if your motors if your motor is rated for less amps.
