IMPORTANT SAFETY NOTES
OPERATION:
Flight:
Take responsiblity for the safety of yourself and others when flying the X4!
Do not fly the X4 in crowded places.
Do not fly in bad weather.
Never try to catch the X4 while it is in flight.
This model is intended for experienced pilots age 14+.
Power off the X4 after flight, to prevent the propellers from causing injuries.
Always remove the battery after you stop flying to avoid injuries from accidentally
powering on the motors.
Always take great caution to protect yourself when near the propellers.
The flight system will start after powering on regardless of the transmitter signal. The high
speed propellers are very dangerous.
Power off the X4 after every flight or the propellers may still rotate and cause injury.

6.3 FAILSAFE MODE
The drone will enter into Failsafe Mode when the connection is lost from the transmitter. The
flight control system will control the quad copter to return to the home point and land
automatically. The Failsafe Mode helps to avoid further injuries or damages.
CONDITIONS WHICH ACTIVATE THE FAILSAFE MODE
(1) Transmitter is powered off.
(2) The flight distance is beyond the range of the transmitter’s signal transmission.
(3) The transmitter’s signal was interrupted by some other strong electronic interference.
To ensure that the X4 can return safely to its home point when GPS signal is lost, fly
the X4 in safe flight area.
If the quantity of GPS satellites drops below six for more than 20 seconds while the
X4 is returning home, the X4 will descend automatically.
The X4 will not avoid obstacles automatically while in failsafe mode.
!The RTH MODE only works when the GPS with no less than 6 satellites.
6.2 RTH MODE
ENTER/ EXIT RTH MODE
Press the RTH button for 1.5 seconds, and the drone will enter into RTH mode. The flight control
