READY TO FLY AND CLOSE

BOOT UP

Place the Drone on a horizontal plane after deployment, and long press to open the fuselage.
Power button, light flashing, in standby mode.
Note: the tail of the quad copter is aimed at the controller

PAIRING

Long press to turn on the power switch of the remote control, the Drone fuselage light turns to normal light, and the frequency matching is completed.

HORIZONTAL CALIBRATION

Lower the left control lever of the remote control 45 degrees to the left Corner right lever down right 45 ° .
The remote control emits a “drip” sound and the light of the fuselage flickers and always turns on to complete the horizontal calibration.

START THE QUADCOPTER

Method 1:
Move the left control lever of the remote control down 45 ° to the left / the right control lever down 45 ° to the right, the remote control makes a “drip”, the propeller blades rotate slowly, and the aircraft is unlocked.

Method 2:
After the aircraft is unlocked, push the left joystick of the remote control upward, and the propeller accelerates to rotate and fly off the ground.

Method 3:
When the aircraft is at a standstill after frequency matching, press the “one button take-off” button on the remote control. After the aircraft propeller rotates slowly, it will automatically rise to an altitude of about 1.2m and hover.

TURN OFF THE QUADCOPTER

Method One:
Push the left joystick(Accelerator) to the lowest level an hold there for 2 to 3 seconds , the quadcopter can then be turned off.

In the headless state, it is biased towards the front direction|

1. Many collisions may cause head biasness.

|

1. Re-define the front direction. For further details, see on Page 7 for details (Headless Function).

Fixed high  instability / up and down movement|

1. The drone is not calibrated level to the ground.
2. Unstable air pressure under the severe weather condition .
3. Violent collision resulting in data disorder of gyroscope.

|

1. Re-adjust the calibration until the drone is level to the ground. For further details, see on Page 4 for details (Function of horizontal adjustment).
2. Avoid to fly under the severe weather condition.
