Compass calibration
Rotate the aircraft horizontally until the transmitter says "di... "Level correction to
complete. When the left light turns to long light and the right light flashes, enter
vertical correction.
Rotate the vehicle vertically until the transmitter says "di... "A sound, vertical
correction over. The four navigation lights are spinning and flashing.
Level Correction Vertical correction
Tips: It’s a must to have the right compass adjustment first each time you start
the drone, or it can’t work normally.
GPS signal search
After the frequency matching is successful, the drone automatically searches for
GPS signals. When the left blue indicator light of the transmitter changes from
flashing to long bright, indicating that the GPS connection is successful. But if you
don’t connect the GPS, the flight height defaults to about 3 meters.
Unlocking the drone
The drone can only take off when the motor is unlocked.
Push the left and right stick inward to the 45
degree angle simultaneously.
On standby drone, motor rotation, drone
Unlocked.
When the drone is not take off, the motor

After unlocking the motor，press the "take off" button,
and the drone will automatically rise and hover at a
height of about 1.2 meters .
Landing
During the flight，press the“landing”button,
the transmitter make a sound of “di”and the
drone slowly land until landing.
Notice：Don’t operate the left stick during landing, otherwise the current
command will automatically fail.

Automatic return
During the flight, press the "return " button, and the
transmitter will sound "di", and the drone will
automatically return to the take off point.
(during returning, the transmitter will continuously
sound "di". To stop homing, just press this button
again.)
During the automatic return, the remote stick is locked. When the drone returns
to the take off point and aligns with the take off direction, the remote stick is
automatically unlocked.
Following mode
While flying, press left stick down, the transmitter
sounds “di”, drone enters the function of following.
Now it can be controlled by the user.
The function is standard by the mobile phone APP signal,
so it’s a must to make the drone and APP connected
normally, turn on the mobile location service at the same time,
otherwise this function is invalid.
Press down
Encircling flight
In flight, press the right stick down, and the transmitter will make the sound of "di".
Then it goes to the function of encircling flight. The drone will fly to a default radius
then it waits for the direction controlled by the user. Adjust the speed and direction
of the drone by manipulating the right stick. It is the minimum radius of the default
radius acquiescently ,so drone flies only in the sub range.
In the state of
encircling flying,
the left stick could
only control the
height of the drone.
Press down
Turn left, the drone flies clockwise; Move
further, the flying speed will become faster.
Turn right, the drone flies counterclockwise;
Move further, the speed will become faster.
Go upward to narrow the radius of
encircling.

Intelligent Hover
Intelligent flight control can calculate the suspended height ,the visual system points
the ground position,GPS coordinates allow the vehicle to stay in your desired
position Buy. The drone is like a camera fixed in the air. Aerial photography and
control are very convenient.
Notice: Drone must be connected to GPS properly in order to give full play to
fixed-point hovering function. Atmospheric pressure or wind force affects
hovering stability.

the drone to fly back to the return point after receiving the remote control signal
(ie, out of control).
The drone does not have the function of avoiding obstacles during the uncontrolled
return flight. The user can set the return altitude value to avoid obstacles on the way
back.
Possibility of entry into runaway protection mode
* The transmitt is off.
* Flight distance exceeds the effective distance of remote control signal transmission.
* There is an obstacle between the transmitter and the drone.
* Transmitter signal is disturbed.
Flying Trimmer

please push it to the left.
Calibration (This action is used when flying abnormally)
After the calibration of the compass, the
right control lever of the remote control is
pushed to the lower right corner by 45°,
and the remote control emits a sound of
"di",and the aircraft light flashes and
releases,indicating that the gyroscope has
been calibrated.
Tips: When the drone doesn’t appear to use the trim correction flight status, or being hit hard
(or falling abnormally). thus cause the difficulties in controlling. Now frequency making and
adjustment are needed again, drone should be placed on horizontal ground.

Attention
① Switching sequence. At first, turn on the power of the transmitter, then turn on the power
of the drone. After the end, turn off the power of the drone first, and then turn off the
power of the transmitter.
② Improper operation caused the crash. It is necessary to check and confirm the connection
