Arming and disarming

     After power on the copter correctly, execute the arming gesture (move the sticks and 
hold for 1 second as shown in figure below), the copter will be armed (green light on), all 
motors will begin to spin slowly, you can raise the throttle to take off; if throttle keeps down 
over 3 seconds, the copter will disarm again (red light on, all motors stop).

Note: If you execute arming gesture when MG25 is armed, MG25 will disarm 

          again immediately.

MG25 stick range calibration & ESC calibration

     Stick range calibration makes control of MG25 more precise, MG25 provides a simple 
way to calibrate stick range: Turn on the transmitter, put the throttle stick at maximum 
position, and then connect the battery, both red and green LED on MG25 will on, that 
means MG25 has entered stick range calibration mode. After that, pull the throttle stick 
down to its minimum position until all LEDs are off, stick range calibration is finished.

Note: 

     1.All channels must be set to a same travel.
     2.During this process, all MG25 outputs are same as your throttle, so you can connect all 
ESCs to MG25 outputs so that ESC throttle calibration can be done at the same time.

9.Settings

     MG25 can be connected to PC via USB link module, connect these as shown in figure 
below.
