8.1 Place the aircraft horizontally on the ground and long press the aircraft switch for 3 seconds. When the aircraft body light flashes, it will automatically enter the frequency matching state.
Note: Set the aircraft in a correct direction, and the nose shall face forward. It must be placed on the horizontal plane.
8.2 Turn on the remote control (default mode)-press the power switch keyon the remote control 
(step 1) to turn on the remote control power, the indicator flashes, first push the throttle stick up to the top (step 2) and then to the bottom (step 3), when the body light is always on, it means that the frequency is successfully matched, and the remote control indicator is always on.
It must ensure that the power of the aircraft/remote control is sufficient or it cannot take off!
8.3 Horizontal calibration operation:
After completion of the frequency matching of the aircraft, place the aircraft on a flat ground, short press the calibration key 
, the remote control emits a beep, and the aircraft light start to flash quickly and being always on, which means the horizontal calibration is completed (Figure 1).
Note: The calibration must be completed only when the aircraft is placed on a horizontal plane. Figure 1
8.4 Start/stop
Push up the left joystick on the remote control (Figure 2). At this time, the aircraft motor starts and the blades rotate, short press the key , the aircraft motor slowly stops rotating (Figure 3).
8.5 One-key take-off and landing
After the level calibration is completed, long press the remote control function key (Figure 4), the aircraft will automatically rise to a height of about 1 meter, and maintain this altitude for stable flight; short press this key during flight, the aircraft will automatically land slowly on the ground.
8.6 Emergency stop
When normal control is not possible during the flight, long press the speed key, the remote controller will make a beep, and the aircraft will immediately stop flying (Figure 5).
9. 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 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.
Fine tuning function

- Fine tuning of aircraft deviates to the left/right When the aircraft leaves the ground and the aircraft deviates to the right, press and hold 3 left fly fine-tuning key to adjust, and when the aircraft deviates to the left, press and hold 4 right fly fine-tuning key to adjust.
10. Introduction of remote control function and operation
10.1 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 5). When exiting, please tap gently press this function key again.

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 7). 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.
10.3 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 8).
10.4 Roll
When the basic movements are very proficient, you can play some thrilling rolling actions. After flying the four-axis drone to an altitude of more than 3 meters, press the roll key 
in the upper right corner of the remote control (Figure 9), and at the same time turn the right joystick left/right to roll the drone left/right. (Figure 10)
Note: The rollover effect is best when the battery is fully charged.
