ESC Calibration (Electronic Speed Controller)
The purpose of ESC calibration is to match the PWM value output by the flight control with the range of
PWM values that the ESC can receive.
The Paladin system provides two ESC calibration methods(take HOBBYWING ESC for example):
·General steps of ESC calibration(ESC signal line disconnected to flight control):
a. Connect a single ESC signal line to the receiver Channel 3(Accelerator Channel);
b. Power on the remote control, push the accelerator to the highest position, power on the ESC, hear "Di -
Di" twice, pull the accelerator to the lowest position, hear "Di - Di - Di" three times, then push the
accelerator, motor rotates, calibration completed;.
c. Repeat the above steps for other ESC calibration;
· Flight control ESC calibration steps(ESC signal lines and receivers have access to flight control):
d. Power on the remote control, push the accelerator to the highest position;
e. Power on the flight control, indicator lights flashing red and blue, flight control enter the ESC calibration
mode, turn off the power of flight control, the remote control maintains the highest position;
f. Re-power the flight control, turn on power system, when hear the ESC "beep - beep" sound, pull the
accelerator to the lowest position immediately, at this point will hear "Di - Di - Di" three times, then push the
accelerator again, motor rotates, calibration completed.
ESC calibration must be propeller-free, the audible tones of ESC calibration may be different by
different manufacturers, please refer to the manual of ESC .
