* Users need to calibrate the throttle range when they start to use a new XRotor brushless ESC or another transmitter; * Users can change the timing advance when some abnormality occurs in ESC driving the disc-type motor or need the motor to reach a higher RPM. (Note: Intermediate Timing is the default setting.)
Step 1: Motor Wiring
Step 2: Radio Calibration
Warning! This is an extremely powerful brushless motor system. We strongly recommend removing your propellers for your own safety and the safety of those around you before performing calibration and programming functions with this system.
Step 3: ESC Programming (For XRotor-10A、XRotor-20A、XRotor-40A)

Notes: Generally speaking, low timing is applicable for most motors and it brings higher efficiency but less heat to the power system. High timing can increase the RPM of the motor, but it also increase the motor temperature. Therefore, please have a test flight on the ground and ensure everything is ok first, and then you can fly your aircraft into the sky.
【Normal Start-up Process】
Start-up Protection:
The ESC will shut down the motor after it fails to start the motor normally in 2 seconds by increasing the throttle value. In this case, you need to move the transmitter throttle stick back to the bottom position and restart the motor. (Possible causes to this problem: poor connection or disconnection between the ESC and motor wires; propellers are blocked or others.)
Over-load Protection:
The ESC will cut off the power/output when the load suddenly increases to a very high value and it won’t get back to normal operation until the throttle stick is moved back to the neutral position. Besides, the ESC will automatically attempt to restart when the motor and the ESC are out of sync. Throttle Signal Loss Protection: When ESC detects loss of signal for over 0.25 second, it’ll cut off the output immediately to avoid even greater loss which may be caused by the continuous high-speed rotation of propellers or rotor blades. And the ESC will resume the corresponding output after usual signals are received normally.
Trouble |
Warning Tone |
Possible Cause |
Solution |
The ESC was unable to start the motor. |
“Beep beep beep…” (The motor beeps rapidly) |
The throttle stick is not at the neutral position or the throttle range is too narrow. |
Move the throttle stick to the bottom position or recalibrate the throttle range. |
The ESC was unable to start the motor. |
“Beep, beep, beep......” (Time interval is 1 second) |
No output signal from the throttle channel on the receiver. |
Check if the transmitter and receiver are well bound; Check if the throttle wire has been properly plugged into the throttle channel on the receiver. |
The ESC was unable to start the motor. |
“Beep beep, beep beep beep, beep beep beep beep”(these tones are played circularly) |
Incorrect “Normal /Reverse” direction of the throttle channel. |
Refer to the transmitter vendor instructions and reset the Normal/ Reverse direction of the throttle channel. |
