Pre-flight preparation instructions (using remote control)
9.1 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.
Note: Set the aircraft in a correct direction, and the nose shall face
forward. It must be placed on the horizontal plane.
9.2 Press and hold the power switch button of the remote control ****(step 1),
and the power indicator of the remote control will be on; push the throttle
lever up to top (step 2) and then to the end (step 3), code-matching will
succeed, and the aircraft light will change from flashing to be always on.
The aircraft/ramote controller must ensure sufficient power or it cannot take
offt
9.3 Horizontal calibration operation:
Press and hold the calibration button on the remote control , the LED light on
the aircraft flashes quickly. The LED lights on the aircraft are always on,
which means the calibration is complete, and the remote controller emits a
“beep” (Figure 1).
Note: The calibration must be completed only when the aircraft is placed
on a horizontal plane.
9.4 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 Me key, the aircraft will stop flying (Figure 3).
Note: This function operation i s only suitable for the aircraft i n an
uncontrolled state. Under normal circumstances, it is recommended t o use the
key takeoff/one-key landing & key.
9.5 One-key take-off and landing
When the frequency matching i s completed, lightly press the remote control
“one-key takeoff/landing” button (Figure 4), the aircraft will automatically
rise to a height of about 1 meter, and keep flyingat this height; when this
function key is pressed again, the aircraft will automatically land on the
ground slowly.
Operate the aircraft with the remote control . Before taking off, please
operate according to the above sequence: Turn on (refer to 9.1)—> frequency
matching of the remote control starts (refer to 9.2)—horizontal alignment
(refer to 9.3)—start/stop (refer to 9.4)— one-button taking off and landing
(refer to 9.5 )
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 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 :
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. 
11.1 360° 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.

12.2 One key return
When the flying distance o f the aircraft is too far, the aircraft can be
recalled with the retum 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 .
12.3 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).
