Aircraft Components

2. Name of each part of aircraft:

• Obstacle Avoidance Radar
• Fan blade
• LED lights
• Camera
• Battery
• Power switch
• Shell
• Motor
• Bottom camera

360° four-way obstacle avoidance: The obstacle avoidance switch is off by default. It can be turned on by briefly pressing the obstacle avoidance key. Pressing it again turns it off. During flight, if the aircraft approaches obstacles in the front, back, left, or right directions, it will automatically move to a safe area because the obstacle avoidance function is active.

Installation and Setup

3. Installation figure of aircraft protection ring: Align the parts of the frame with the socket of the arm as shown in the figure. Ensure the installation is secure before flying to prevent the aircraft from falling.

Note: Please be sure to install the protective ring before flying!

4. Wind blade installation diagram: Remove the fan blade. If an A1/A2 blade is broken, replace it with an A1/A2 blade. If a B1/B2 blade is broken, replace it with a B1/B2 blade. Replacing with the wrong parts will prevent the aircraft from taking off.

Note: The fan blade is printed with A1/A2 and B1/B2. Please install it correctly according to the instruction, otherwise it cannot take off.

5. Unfolding steps of the aircraft: (The aircraft is in a storage state when it leaves the factory)

1. Flip open the cover.
2. Press the arrow-indicating button to remove the aircraft.
3. Unfold the aircraft according to the steps.

Battery Charging

6. Lithium battery charging instructions:

1. Buckle the battery lock of the aircraft.
2. Remove the battery.
3. Charging: Insert the USB port of the USB charging cable into a computer USB port (or use a 5V 2A power adapter). Connect the other end of the USB charging cable to the battery socket. The red indicator on the battery module is on during charging. When the battery is fully charged, the red indicator light goes out.

Warning: It must be charged with the aircraft charging cable provided by the factory. Other charging cables cannot be used. Be sure to remember to avoid accidents.

Remote Control Battery Installation

8. Remote control battery installation:

• Remove the battery cover.
• According to the polarity instructions on the battery compartment, insert 2X "AAA" batteries (not included).

Instructions in charging:

• Do not hit or beat the battery surface with hard objects.
• Do not disassemble the battery.
• Do not immerse the battery in water. Store batteries in a dry place. Do not leave batteries unattended while charging.

Note: 1. Identify the positive and negative poles of the battery and the battery box correctly. Errors are not allowed. 2. Do not mix old and new batteries. 3. Do not mix different types of batteries.

Warning: When not flying, please do not install the battery in the aircraft to avoid battery damage.

Pre-Flight Preparation

9. Environmental requirements before flight: Please choose an outdoor, open environment with no rain or snow and low wind. Stay away from crowds, trees, wires, tall buildings, airports, and signal transmission towers. Do not fly in small indoor environments with many obstacles.

10. Preparation instructions before flight (using remote control):

1. Aircraft frequency matching: Turn on the aircraft's power and place it on a horizontal surface. The aircraft will automatically enter the frequency matching state, and the front white light and rear red light will flash.

Note: Set the aircraft in the correct direction with the nose facing forward. It must be placed on a horizontal plane.

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). Frequency matching is successful when the UAV lights change from flashing to being permanently on.

Warning: The aircraft/remote controller must have sufficient power to take off!

10.3 Horizontal calibration operation: Long press the calibration key on the remote controller. The LED lights on the aircraft will flash. When the LED lights are on, calibration is complete, and the remote controller emits a "beep" (Figure 1).

Note: Calibration must be completed on a horizontal plane.

10.4 Start/stop: Push the left control lever upward (Figure 2). The aircraft can take off. After takeoff, all indicator lights will be on. During flight, short press the [stop] key to stop flying (Figure 3).

Note: This function is suitable for uncontrolled states. For normal circumstances, use the one-key takeoff/one-key landing key.

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 about 1 meter for stable flight. Press the key again to land slowly.

Warning: Operate the aircraft with the remote control. Before taking off, follow the sequence: turn on (10.1) → frequency matching (10.2) → horizontal alignment (10.3) → start/stop (10.4) → one-button takeoff and landing (10.5).

Remote Control Functions

11. Introduction of remote control function and operation:

11.1 Remote control method:

• Ascend/Descend: Push the left joystick (throttle) up to increase blade rotation rate and ascend. Push down to decrease rotation rate and descend.
• Yaw Left/Right: Push the left joystick (rudder) left to turn the aircraft nose left. Push right to turn the nose right.
• Move Forward/Backward: Push the right joystick (rudder) up to move forward. Push down to move backward.
• Lateral Movement (Crab): Push the right joystick (rudder) right to deviate right. Push left to deviate left.

11.2. 360° roll: The aircraft can perform a 360° roll. For best results, maintain a height of about 1.5 meters and perform the roll during ascent.

• 360° roll on the left: Short press the 360° roll button, then push the right joystick to the left.
• 360° roll on the right: Short press the 360° roll button, then push the right joystick to the right.
• Roll Forward 360°: Press the 360° tumble button briefly, then push the right joystick upward.
• 360° roll backward: Short press the 360° roll button, then push the right joystick down.

11.3 Speed switching: When the aircraft takes off, it defaults to low-speed mode (3-geared switching). Press the remote control for one "beep" for low-speed, two "beep"s for medium-speed, and three "beep"s for high-speed (Figure 7).

11.4 One key return: If the aircraft flies too far, use the return function. When code-matching, the remote control must face the tail of the aircraft. During flight, press and hold the one-key home button (Figure 6). When the remote control beeps, the aircraft enters the one-key home function and returns automatically. Operating the joystick will release the home function.

11.5 Headless mode: The front of the aircraft at startup is the default front in headless mode. To adjust direction, restart code-matching, enter the APP, expand the function menu, and click the headless mode function (Figure 5). To exit, press the function icon again.

Special prompt: Ensure the aircraft is aligned with a straight line and let the gyroscope detect it for straight-line headless flight.

11.6 Fine tuning function:

• 1. Fine tuning of aircraft moving forward/backward: When the aircraft deviates backward after leaving the ground, press and hold the forward fine-tuning button (1). When it deviates forward, press and hold the backward fine-tuning button (2).
• 2. Fine tuning of aircraft deviates to the left/right: When the aircraft deviates to the right, press and hold the left fly fine-tuning key (3). When it deviates to the left, press and hold the right fly fine-tuning key (4).

11.7 Obstacle avoidance mode: During flight, short press Obstacle Avoidance [icon] to activate the mode. The aircraft will move to a safe area when near obstacles. To switch back to normal fixed height mode, lightly press the key again to turn off obstacle avoidance.

Note: Obstacle avoidance may be weakened or ineffective under strong sunlight, transparent/reflective objects, or black objects.
