12.1 Aircraft code matching. Turn on the power of the
aircraft and place it on a horizontal plane. At this
time, the aircraft placed on the horizontal plane will
automatically enter the state of code-matching. The
light of fuselage will flash from fast to slow (battery
indicator is always on).

12.3 Turn on the remote control (default mode)-press the
power switch button of the remote control (step
1) and turn on the remote control, the power
indicator will flash. The throttle lever is pushed up to
the top (step 2) and then to the bottom (step 3), the
code matching will complete and the indicator of the
remote control will be always on.
12.4 Horizontal calibration operation:
Push the left and right joysticks on the remote control to the lower right corner at the same time, and the lights
on the aircraft will flash quickly. When the lights on the aircraft flash slowly, it means the calibration is
complete, when the remote control will emit a sound of beep (Figure 1).
APP operation: Click the "Set more" icon in the APP interface, and operate following the text prompt after
entering, and it can also be horizontally calibrated. When the APP indicates that the
calibration is complete, it will automatically proceed to the next step (Figure 2).
Note: The calibration must be completed only when the aircraft is placed on a horizontal plane.
1. Short press the
geomagnetic
calibration button
until the light on the
aircraft flashes quickly.
2. Horizontal clockwise rotation -
Pick up the aircraft horizontally
and rotate clockwise until the
device emits a sound of "beep",
and the horizontal calibration is
completed.
3. Rotate the aircraft clockwise with the
tail upwards: pick up the aircraft with
the nose being vertically downwards
and rotate clockwise until the remote
control emits a sound of "beep" when
the light flashes slowly, which means
the guide calibration is completed.
APP operation: In the interface of "Set more", according to the text prompt and operation steps, the guide
calibration can also be done (Figure 4). When the APP prompts that the guide calibration is
complete, it will automatically enter the start to fly interface.

12.6 Star search status
After the code matching is completed, the remote control is turned on. The remote control displays Mode-1, and
Mode-1 is optical flow mode. At this time, the aircraft will automatically enter the star search mode. If the star
search is successful, the remote controller will emit a “beep” as a prompt. Mode-1 changes to Mode-2, which
means it is unlocked and can take off.
Note: The first time of star search needs to wait at least a few minutes, and the search signal reaches about
10 stars before it can take off.Note: The calibration must be completed only when the aircraft is
placed on a horizontal plane.
12.7 Start/stop (GPS mode)
Push the left and right joysticks on the remote control outward to unlock, (if the star search is unsuccessful, it
cannot be unlocked and started) (Figure 5). At this time, the aircraft can take off normally. After taking off, all the
indicators of the aircraft are always on.
APP operation: Click "One Key Unlock" icon (Figure 6) in APP control interface, the one-key unlock function can
also be achieved.
12.9 Normal mode (Optical flow assisted positioning)
The aircraft enters the normal mode: when flying above a good ground, optical flow will assist the aircraft. When
hovering in a place, it will be normal to drift about 1 meter depending on the ground and altitude conditions.
12.8 One-key take-off and landing
When unlocking is complete, gently press the “One Key Takeoff/Landing” key on the remote control (Figure
7), 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.
APP operation: Click "one-key take-off" icon (Figure 8) in APP control interface, the one-key take-off function can
also be achieved; during flight, click this icon again, the aircraft will automatically land slowly.

(Optical flow positioning) (Refer to 12.9) → Start / stop (the normal mode needs to be turned on for the indoor
operation) (refer to 12.10).
13. Control method:
APP operation: Enter the APP control interface, and click the "joystick on / off" icon; the operation joystick will
be seen on the interface and the operation method is as follows:
08
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 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
up, the aircraft moves forward.
When the right joystick (rudder) is pushed
down, the aircraft moves backward.
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.

Warning
14. Introduction to the APP application and remote control function operation:
14.1 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 14). When exiting, please tap gently press this function key again.

14.2 One key return
When the aircraft is in 1m from the ground, the aircraft will become unstable due to the
influence of its own blade vortex, which is called "ground effect response". The lower the
height of the aircraft, the greater the effect of the ground effect response.
Press the one-key return button , the aircraft will return to the place above the geomagnetic calibration position
(Figure 14). (The aircraft will automatically rise to a safe altitude when it is flying below the safe altitude) and then land
slowly. If there are obstacles during the landing, press the one-key return button again to turn off the return operation
and avoid by the manual control joystick, pull down the throttle lever to land.
APP operation: Click the "one-key return" icon (Figure 15) in the APP control interface, you can also return the aircraft;
during the return flight, click this icon again to cancel the return.
One key

End point
Runaway return: When the signal of the remote controller is interrupted for about 4s, the aircraft will
automatically return to the place where there is a signal and stop.
Low battery return: when the aircraft is in low battery electricity, it will forcefully return to a place that
is 20m above the take-off point. The return flight cannot be cancelled during the low battery return.
Speed adjustment wheel: when it turns right, the remote control will "beep" twice to enter the high
speed mode, and when it turns left, the remote control will "beep" once to enter the low speed mode
(Figure 16).
APP operation: Click the "More Functions" icon (Figure 17) in the APP control interface, and the flight
speed can also be switched (Figure 18).
