WARNING AND THE GUIDE OF BATTERY USAGE

WARNING: lt is recommended to use the original power supply charger when charging,  otherwise property damage and injury will occur

Notice: When it is lower than 7.4V, the lithium battery may be damaged, or itmay no longer be charged. When the battery voltage is lower than 7.4V when the aircraft is flying, the power of the aircraft drops significantly.Please immediately land and charge the battery in time.

BATTERY CHARGING

• 1. The user should connect to the power adapter with a USB port or connect to the USB port of computer.
• 2. Connect the USB cable to the power adapter, at the same time the USB charger red light flashes.
• 3. The partial voltage charging head of the battery is connected with the USB cable. At this time, the USB charger’s red light always on and charging is in progress.
• 4. When the USB charger red light is off, charging is completed

NOTICE BEFORE FLIGHT:

1. Check if the transmitter power supply is sufficient, whether the helicopter power supply is sufficient
2. Please make sure the transmitter throttle stick is at the bottom when turning on the transmitter
3. Confirm if the transmitter and the helicopter are in the same frequency, re-check the code if it is abnormal
4. Firstly turn on the transmitter when powering on, then connect the battery to the receiver for binding. Firstly unplug the cable between the battery and the receiver when powering off, and then turn off the transmitter.
5. Find a suitable place for safe and happy flying. Keep away from crowds, cars, high-voltage towers, ponds, etc.

BINDING BETWEEN THE TRANSMITTER AND RECEIVER

1.  Turn on the remote control, the remote control emits a long beep, and the power indicator of the remote control flashes
2. Power on the aircraft, the receiver indicator flashes, move the throttle stick to the uppermost position and then to the lowermost position, the remote control emits a beep, and the remote control light is solid on and the receiver board indicator light is solid on, the binding is completed.
3. If the binding is unsuccessful, please disconnect the power of the aircraft, turn off the transmitter, repeat the above steps to bind again.

AIRCRAFT HORIZONTAL CALIBRATION

1. When the aircraft appears obvious orbit deviation, the flight attitude can be corrected by horizontal calibration.
2. Hit the left and right joystick at the same time to the bottom left corner for 1-2 seconds as shown, At this time, the aircraft indicator light enters quick flashes. The aircraft enters the horizontal calibration, waiting for the aircraft indicator lights return to long light, the calibration is completed.

Special note: calibration needs to find a relatively flat field, as far as possible to ensure that the aircraft and the ground at the same level. After the aircraft enters the calibration procedure, it shall be ensured that the aircraft is still, and the aircraft cannot be moved until the calibration is completed.

HOVER SETTING

The aircraft you purchased has been set before leaving the factory. If the aircraft cannot enter the hover well, you can set it through the following steps.

1. Power up the plane, match the frequency and take off.
2. In flight, long press the hover setting button to enter the setting. The remote control makes a dripping sound and the indicator light starts to flash.
3.  According to the yaw direction of the aircraft, push the Trim Button of the corresponding channel in the opposite direction until the aircraft hovers smoothly.
4. Land the aircraft and press the hover setting button to exit the setting. At this time, the remote control will emit drops and the indicator light will return to always on.
5. Restart the plane and reset the power of the remote, matching again for fly.

INITIAL FLIGHT
