1. The positive and negative poles and the positive and negative poles of the battery box must be identified when inserting the battery, and error is not allowed.
2. Do not mix old and new batteries.
3. Do not mix different types of batteries.

Environmental requirements before flight:

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.
APP can only be viewed (photographed/recorded) when using the remote controller, and the remote controller cannot be used when using APP.

Pre-flight preparation instructions (using remote control):

8.1 Aircraft frequency 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 frequency matching state, and the fuselage lights will flash.
Note: Set the aircraft in a correct direction, and the nose shall face forward. It must be placed on the horizontal plane.

8.2 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.

It must ensure that the power of the aircraft/remote control is sufficient or it cannot take off!
8.3 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).
Note: The calibration must be completed only when the aircraft is placed on a horizontal plane.

8.4 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).
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.

8.5 One-key take-off and landing
When the frequency matching is 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 flying at this height; when this function key is pressed again, the aircraft will automatically land on the ground slowly.

Please follow the steps in the above sequence before taking off: open (reference 8.1)→ remote control starting frequency matching (reference 8.2)→ horizontal calibration (reference 8.3)→ start/stop (reference 8.4)→ one-button take-off and landing (reference 8.5)

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 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.

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.

| 10.1 360° 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.
---|---
| 10.2 360° 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.

Introduction of remote control function and operation:

11.1 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.
Special tip: 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.

11.2 One-key return
The return function can be used to recall the aircraft when the flight distance of the aircraft is too long. The remote controller must be facing the tail of the aircraft when starting up and frequency matching. During the flight, long press the “Return” key ****(Figure 6). The remote controller sends out a “beep” sound, the aircraft enters a key to return home and automatically flies back to us. When the right rocker is operated arbitrarily, the return function is released.

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 A. Taxi take off:
Place the aircraft on a horizontal plane, and push the right joystick upwards to make the aircraft glide close to the ground for a certain distance and then take off.

11.5 Fine tuning function

Gesture photo: About 2m in front of the aircraft lens, raisethe palm of ore 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.)

16.5 MV interface
Click the “filter interface” icon (Figure 18) in the APP control interface, after entering the filter interface, you can choose to match your favorite filter effect, click the recording icon to start recording (Figure 19).

Special tip: 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.

FAQ and solving guidelines:

2.1 Blade deformation
2.2 Installation error of ABC propeller| 1. Charge the battery
2.1 Replace the blade
2.2 The fan blades are printed with letters A, B and C. If fan blade A is broken,
replace A, and if fan blade B is broken, replace B, so does fan blade C.
The aircraft vibrates badly| Blade deformation| Replace the blade
Fine tuning is done but still can’t make the aircraft stable| 1.Blade deformation
2.Defective motor| 1.Replace the blade
2.Replace the motor
After the impact, start the aircraft again and it fly uncontrollably| The three-axis acceleration sensor loses its balance due to
impact| After leaving the aircraft for 5-10 seconds, or by the horizontal calibration, it will be ok.
For the steps, please refer to the manual, 8.3 horizontal calibration operation.
