10.1 Aircraft frequency matching: Turn on the power of the
aircraft and place it on a horizontal surface. At this
time, the aircraft placed on the horizontal surface will
automatically enter the frequency matching state, and
the front white light and the rear red light will flash.
10.2 Turn on the remote control (default mode): long press
the power switch button (step 1), turn on the power
and the indicator flashes; push the throttle lever up to
the top (step 2) and then to the bottom (step 3), and
thus the frequency matching is successful, the UAV
lights change from flashing to being permanently on.
Please choose an outdoor and open environment with no rain and snow and low wind. Please stay
away from crowds, trees, wires, tall buildings, airports, and signal transmission towers when flying. Do
not fly in a too small indoor environment with lots of things.
The aircraft/remote controller must ensure sufficient power or it cannot take off!
Note: Set the aircraft in a correct direction, and the nose
shall face forward. It must be placed on the horizontal
plane.

Note: The calibration must be completed only when the aircraft is placed on a horizontal plane.
Note: This function operation is only suitable for the aircraft in an uncontrolled state. Under normal
circumstances, it is recommended to use the one-key takeoff/one-key landing key.
10.3 Horizontal calibration operation:
Long press the calibration key on the remote controller, and the LED lights on the aircraft will flash.
When the LED lights on, calibration of the aircraft is completed, the remote controller emits "beep"
(Figure 1).
10.4 Start/stop
Push the left control lever on the remote control upward (Figure 2). At this time, the aircraft can take off
normally. After taking off, all the indicator lights of the aircraft will always be on. During the flight, whether
you short press the key, the aircraft will stop flying (Figure 3).
10.5 One-key take-off and landing
When unlocking is complete, gently press the “One Key Takeoff/Landing” key on the remote control
(Figure 4), the aircraft will automatically rise to a height of about 1 meter to maintain a stable flight; when
you press this function key gently again, the aircraft will automatically land slowly.
Operate the aircraft with the remote control. Before taking off, please operate according to the
above sequence: Turn on (refer to 10.1)→ frequency matching of the remote control starts
(refer to 10.2)→horizontal alignment (refer to 10.3)→ start/stop (refer to 10.4)→ one-button

11.1 Remote control method:
When the left joystick (throttle) is pushed up, the
rotation rate of the main blade increases and the
aircraft rises.
When the left joystick (throttle) is pushed down, the
rotation rate of the main blade slows down and the
aircraft descends.
When the right joystick (rudder) is pushed up, the
aircraft moves forward.
When the right joystick (rudder) is pushed down, the
aircraft moves backward.
When the left joystick (rudder) is pushed to the left,
the aircraft nose turns to the left. When the left
joystick (rudder) is pushed to the right and the nose
of the aircraft will turn to the right.
When the right joystick (rudder) is pushed to the
right, the aircraft fuselage deviates to the right.
When the right joystick (rudder) is pushed to the left,
the aircraft fuselage deviates to the left.
360° roll on the left
Short press the 360° roll button, then push the right
joystick to the left, and the aircraft will flip 360° to the
left accordingly.
360° roll on the right
Short press the 360° roll button, then push the right
joystick to the right, and the aircraft will flip 360° to
the right accordingly.
11.2. 360° roll
The aircraft can achieve 360-degree flight by the following joystick operation. In order to better perform
the roll function, a height of about 1.5 meters shall be ensured between the aircraft and the ground. It is
best to operate the aircraft to roll during the ascent stage, so that the aircraft can maintain the height
more easily after rolling.
11. Introduction of remote control function and operation:
07

Roll Forward 360°
Press the 360° tumble button for a short time, then
push the right joystick upward, and the aircraft will
turn forward 360°correspondingly.
360° roll backward
Short press the 360° roll button, then push the right
joystick down, and the aircraft will flip 360° backward
accordingly.
11.3 Speed switching
When the aircraft takes off, it is by default in the low-speed mode (3-geared switching); gently press the
remote control by a "beep" sound for low-speed gear, two "beep" sounds for medium-speed gear, and
three "beep" sounds for high-speed gear (Figure 7).
11.4 One key return
When the flying distance of the aircraft is too far, the aircraft can be recalled with the return function.
When turning on the code-matching, the remote control must be directly facing the tail of the aircraft.
During flight, press and hold the one-key home button (Figure 6). When the remote control emits a
"beep" sound, the aircraft will enter the one-key home function, and will automatically return to our side;
when the joystick is operated in any form, the aircraft will be released from the home function.

Special prompt: Please make sure the aircraft is aligned with the straight line and let the gyroscope
automatically detect the straight line, and the headless mode of straight line flight can be realized.
Note: Under sunlight or strong light, under transparent and reflective objects such as glass, and
under black objects, the obstacle avoidance effect will become weak, or even lose its effect.
11.5 Headless mode
The front of the aircraft when the code-matching is turned on is by default the front in headless mode; if
it is necessary to adjust the direction, please turn on the code-matching again, and short press the
remote controller "headless mode" function key (Figure 5). When exiting, please tap gently press
this function key again.
11.7 Obstacle avoidance mode
During flight, short press Obstacle Avoidance to turn on obstacle avoidance mode (Figure 6). Thus,
when the aircraft is close to wall or other obstacles in front/left/right direction, it will automatically move
to a safe area it is in the obstacle avoidance function. If you want to switch to the normal fixed height
mode, lightly press this key to turn off the obstacle avoidance function.

Special prompt: During the recording process, you can rotate the screen or switch the filter effect, and
you can also turn the joystick on / off to control the direction and altitude of the aircraft.
Correct gesture Wrong gesture
Gesture photo: About 2m in front of the aircraft lens, raise the palm
of one hand (palm forward) to a horizontal level on the side of the
body; after the aircraft recognizes the gesture, start a 3-second
countdown and take a photo (the arm can be lowered at this time)
(the time difference between two consecutive recognitions should
be greater than 3s) (some models do not support this function,
turning on the function will cause delay of screen)
Gesture recording: About 2m in front of the aircraft lens, make a fist
with one hand (palm forward) and raise it to a horizontal level on
the side of the body; after the aircraft recognizes the gesture, start
a 3-second countdown and start recording (you can put your arm
down at this time). When the fist gesture is recognized, the
videoing will end. (The palm will not be detected during videoing.)
