I have a marginal problem with my ESC I use Quattro 20AX4, I arm the motors, then start increasing the value of the throttle to turn up the motors, however at low values, I notice that not all motors are turning,
only two and not at the same speed, then I push the throttle to half to obtain sufficient thrust that enable the drone to take off.
when flying the drone drift a little bit, I’m not sure if the ESC causes this problem. I would like to know if
someone of you have had the same experience.
