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.
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
Push the left and right stick inward to the 45
degree angle simultaneously.
On standby drone, motor rotation, drone
Unlocked.

to the take off point and aligns with the take off direction, the remote stick is
automatically unlocked.
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.
Encircling flight
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

Calibration (This action is used when flying abnormally)
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.
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.
Out of Control Protection
Flying Trimmer
Out of control protection refers to the flight control system automatically controls
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.
* 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.

Parameter
①Switching 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.
②Improper operation caused the crash. It is necessary to check and confirm the connection
