Mission Planner Setup
After setting failsafe on transmitter, power it off and check the FAILSAFE menu on MP if the
PWM value of CH3 is smaller than 975. If yes, than the FAILSAFE function is successfully set.
Otherwise, the above steps need to be repeated.
In the RADIO block on the right of the sheet, set ENALBLED always RTL and FS Pwm as 975.
2.2.4 ESC Calibration (First flight)
ESC calibration varies depending on different ESC brands, so it’s advised to refer to the ESC
instructions. Never install propellers before calibrating ESC for safety.
(1) Make sure the aircraft is well connected and radio calibration is done and can be armed;
(2) Toggle the throttle stick to the highest point and power on the aircraft. When seeing the LED
on flight controller is flashing with red/blue/yellow, power it off. The flashing colorful LED
means the aircraft is ready to go into ESC calibration mode next time repower.
(3) Repower on the aircraft, wait to check if the LED flashes (about 30s). Then long press the
safety button until hearing the musical tone (the regular number of beeps indicating battery’
s cell count i.e. 3 for 3S, 4 for 4S) and then an additional two beeps to indicate that the
maximum throttle has been captured.
(4) Pull the transmitter’s throttle stick down to its lowest position, another musical tone will be
heard, meaning the Minimum throttle has been captured and the calibration is complete.
(5) Push the throttle a bit to test if the ESC spin. If yes, then the calibration is done with success. If
no, please repeat the above steps to recalibrate.
