Calibrating the Motor Output

Enter the interface of output calibration of the motor. Pay attention to disassemble the propellers before switching on power.

Follow the instructions on the page to operate: DO NOT connect the battery right now; tick all the precautions first (reality should also meet the conditions), click Start and connect the battery to the aircraft, and then click Stop after hearing a beep from the ESC. Finally, disconnect the battery, and then click Next.


Click Next.


The output calibration means setting the neutral rate for the motor. Follow the steps below:

Step 1: Connect the battery to the aircraft.

Step 2: Press the Start button below and slide the slider to the right until the motor starts to spin.

Step 3: Click Stop. When the motor stops, press Start again to see whether the motor can start itself. Slide the sliders to the left or right to set the critical point of the motor to spin.

Step 4: Please pay attention to the rotation direction of the motor. Ensure the motors are spinning in the correct direction as shown in the diagram. Otherwise, swap any two wires of a motor to change the direction.

Since the output calibration of the Motor 2, 3 and 4 is the same as the Motor 1, just set their neutral rate in the same way as setting the Motor 1.

Note: Pay attention NOT to make the motor spin too slowly because it will give out much heat at the critical point, which may damage the motor.




After setting, select the type of your air frame. For a Q250 quadcopter, choose Current Tuning. And for SF250, please choose QAV250. Then click Next.


Click Save to save the configuration directly to your OpenPilot controller.


After saving, there will be an interface of rebooting your controller. Just wait for a while.
