place and the aircraft will descend steadily.
7. After landing, leave the throttle stick down for 3 to 5 seconds to stop the motors. Return throttle stick to
middle position after the motors have stopped.
You SHOULD NOT execute the CSC during normal flight! This will stop the motors and cause the
aircraft to descend rapidly and drop without any type of control.
（1） When the LED flight indicator blinks yellow rapidly during flight, the aircraft has entered into
Failsafe mode, refer to <Failsafe Function> for details.
（2） A low battery capacity warning is indicated by the LED flight indicator blinking red slowly or
rapidly during flight. Refer to the <Low Battery Capacity Warning Function> for details.
（3） Watch the quick start video about flight for more flight information.
（4） Aircraft and battery performance is subject to environmental factors such as air density and
temperature. Be very careful when flying 3000 meters (9800 feet) or more above sea level, as
battery and aircraft performance may be reduced.
（5） When used with a H3-3D gimbal, a GoPro camera, and the iOSD mini, your Phantom 2 will be very
close to its maximum takeoff weight. It is not recommended that you attach the Phantom 2
propeller guards at this weight. Otherwise, the aircraft will be unable to fly normally.
6.4 Failsafe Function
The aircraft will enter Failsafe mode when the connection from the remote control is lost. The flight control system
will automatically control the aircraft to return to home and land to reduce injuries or damage. The following
situations would make the aircraft fail to receive a signal from the remote control and enter Failsafe mode:
（1） The remote control is powered off.
（2） The remote control is powered on but the S1 is toggled in the position triggering the Failsafe (this must have
been configured in the PHANTOM 2 Assistant).
（3） The aircraft has flown out of the effective communication range of the remote control.
（4） There is an obstacle obstructing the signal between the remote control and the aircraft, essentially reducing
the distance the signal can travel.
（5） There is interference causing a signal problem with the remote control.
Failsafe works differently depending on the mode the aircraft is in when Failsafe mode is initiated whether it is in
the Ready to Fly or Ready to Fly (non-GPS) mode.
Ready to Fly (non-GPS) ---- Automatic landing
The flight control system will try to keep the aircraft level during descent and landing. Note that the aircraft may
be drifting during the descent and landing process.
Ready to Fly ---- Automatic go home and land
The flight control system will automatically control the aircraft to fly back to the home point and land.
