Electrical Calibration
The purpose of electrical calibration is to make the output PWM value of the flight control match the PWM
value range that can be received by the electrical adjustment.Conventional electric calibration methods are as
follows:
turn on remote control, make the accelerator to the highest position;
turn on flight control, flying light is red and blue flashing, means flight control get into the electrical
calibration model,turn off flight control,keep remote control accelerator always on the highest position;
turn on flight control again ,connect electricity to power system, when hear an electrically controlled "di -
di" sound, rapid pulled the throttle to the lowest, at this time will hear a long sound "di",
At this point push the throttle again, motor will be in rotation, electrical calibration will be in end .
