2). Check failure safety(F/S): hold aircraft away from ground, switch CH5 CH6 to manual mode, switch CH9 to “0”
position, turn off remote control, “Flight Mode” display “Back Landing” on GCS software and gear down, it
indicates the setting of failure safety(F/S) is right, user can put aircraft down and turn on remote control and check
other settings later.
3. Motors start guidance: pull throttle joystick to the bottom, switch CH5, CH6 to “0” position, (mode 2 left-hand
throttle as sample), pull left joystick to bottom left corner, right joystick to bottom right corner as “

” type and keep

the action about 3-5 seconds, loose two joysticks, push left throttle joystick slightly to start motors, push throttle
higher slowly and check if motors are controlled normally, while left throttle joystick pulls to bottom again, motors
will stop running.

Notice:

(1) Both manual and auto hovering mode can start motors in this way.

(2) Under auto hovering mode, user needs to push throttle joystick to at least half position before taking off. There
is no limit under manual mode.

(3) Execute the operation, if there is no operation of pushing throttle joystick in 5 seconds, the motors will stop
running and be locked automatically. User needs to execute the operation one more before taking off.
(4) Under manual mode, if throttle joystick is not in bottom position, motors will not stop running.
(5) Under auto hovering mode, if flight height lands to minimum and flight control detects no flight height change,
motors will stop running and be locked automatically.
(6) Under auto navigation and auto back landing mode, all the operations will be completely controlled by flight
control.

(7) Under strong wind flight environment, atmospheric wave is volatile heavily. There is a possibility that motors
cannot stop running under auto hovering and auto back landing mode, in this situation, user only need to pull
throttle joystick to bottom position and switch to manual mode, motors will stop running later.

Magnetic Compass Calibration

F900 aircraft has made magnetic compass calibration before delivery, in general, it is unnecessary to make
calibration again.
