Now the GCS software will automatically switch to the "Control" interface screen and after a period of calculation
will display two circles, a BLUE one and a RED one. The YS‐S4 will enter the magnetic recording and the LED will
now flash GREEN. Calibration will be completed seconds later when the GREEN flash turns OFF.
Excellent
The circles are shown in the picture. If the circles are more or less round, this means the
Calibration has been successful. If not, then you need to do the calibration again.
IMPORTANT:
There is no need to do the Compass calibration every time you fly or upgrade the firmware once your flight
controller component installation and compass calibration has been completed, but it should be done when
components are changed or if the GPS is removed.
7.2 Motor Arming
For safety reasons, the S4 locks the motors on landing. They can only be re‐armed to allow them to rotate and
work after carrying out the "arming" procedure.
IMPORTANT:
Motor arming will fail if the GPS module is not connected.
Enable the "Combined‐Stick‐Command" (CSC) for motor arming as shown below:
To arm, push the left‐hand stick to the far left and extreme bottom, the right stick to the far right and to the
bottom.
This is for Japanese and American convention (mode 1 and mode 2) and is called /\ type. For Chinese and
European operation (Mode 3 and Mode 4), you need to apply the \/ type to arm the motors.
