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.

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

Preparation instructions before flight

1. Fully charge the battery and install it on the body. Short press the power button on the battery twice to turn it on (long press the battery power button to turn it off), 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 blue light and 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.
2. Press the power switch button ” ” on the remote control, and the remote control emits a “beep” sound. Push the throttle lever up and then pull it all the way down. Successfully matched the frequency, the drone light will become constantly on.

Warning: The aircraft/remote controller must ensure sufficient power or it cannot take off!

Horizontal calibration operation:

• Long press the calibration button “ ” on the remote control, and the LED lights on the aircraft will flash quickly.
• The LED lights on the aircraft become constantly on, meaning successful calibration (Figure 1).

Note: In calibration, the aircraft must be placed on a horizontal surface to complete the calibration.

Start/stop

• Push the left joystick on the remote control upwards (Figure 2), and the aircraft can take off normally.
• After take off, all indicators of the aircraft remain on. During flight, pressing the button ” ” will stop the aircraft from 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.

One-key take-off and landing

When unlocking is complete, genlly press the “One Key Takeoff/Landing” key on the remote control (Figure 4), 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.

Warning: Operate the aircraft with the remote control. Before taking off, please operate according to the above sequence: Turn on (refer to 8.1) → frequency matching of the remote control starts (refer to 8.2)→horizontal alignment (refer to 8.3)→ slart/stop (refer to 8.4)→ one-button laking off and landing (refer to 8.5)

Introduction of remote control function and operation

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.

One-click rotation

• Short press the one-click-rotation button on the remote control (Figure 5), and the aircraft will rotate twice at its own midpoint before stopping.
• Pulling the right joystick can also stop rotation at any time.

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 6).

Lighting control

• Short press the light mode button” ” to tum on/off the lights on the aircraft (Figure 7).

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, ii will be normal to drift about 1 meter depending on the ground and altitude conditions.

Fine tuning function

1. Forward fine adjustment: When the aircraft leaves the ground and moves backward, pressand hold the forward fine adjustment button to make adjustments.
2. Backward fine adjustment: When the aircraft leaves the ground and moves forward, press and hold the backward fine adjustment button to make adjustments.
3. Left flying fine adjustment: When the aircraft leaves the ground and deviates to the right, press and hold the left flying fine adjustment button to make adjustments.
4. Right flying fine adjustment: When the aircraft leaves the ground and deviates to the left, press and hold the right flying fine adjustment button to make adjustments.

Gesture recognition

When facing the camera’s front lens, click the gesture photo button on the APP, and use any of the following gestures to trigger the aircraft’s photo or camera function.

Special tip

• Please aim directly at the lens and perform gesture recognition at a position about 2-3M away from the lens and in an environment with good light and background.

Yeah gesture photo

In about 3m front of the aircraft lens, make Yeah gesture with one hand in horizontal position; after the aircraft successfully recognizes the gesture, count down 3 seconds and take photos.

Palm gesture video-recording

In about 3m front of the aircraft lens, put five fingers together and lift one hand to horizontal position; after the aircraft successfully recognizes the gesture, it will start recording. The recording will end when the gesture is re-recognized (the time difference between the two recognitions shall be greater than 3s).
