1.when the ESC’s switch is off:
1.1The motor will keep turning .
1.2The servo that controls the direction is also unresponsive（(This is normal, I know the switch is for controlling the power to the receiver)
2.When the ESC is switched on：（also no sound like bee~bee~bee~)
2.1 I remote control forward, the motor will turn several times.
2.2 When I remote control backwards, the motor does not respond.
So I suspect that the ESC needs to be set for throttle travel, but I followed the generic method but it didn’t work
