Flight Safety Information

+ +
Fly in Open Areas       Maintain Line of Sight    Fly Below 50 m

Avoid flying over or near obstacles, crowds, high voltage power lines, trees, airport or bodies of water.
Do not fly near strong electromagnetic sources such as power lines and those base stations as it may affect the onboard compass.

Do not use the drone in adverse weather conditions such as rainy, snowy, foggy and windy days.

Stay away from the rotating propellers and motors

No Fly Zone

Do not use the drone in adverse weather conditions such as rainy, snowy, foggy and windy conditions.
The basic flight guidelines are import for pilots’ safety and the surroundings. Please read the safety guidelines carefully.

Get Your Drone Ready

• Rotating propellers can be dangerous. Do not start the motor when there are people nearby.
• If the motor is still spinning, always keep your hands on the transmitter.

Pair the Drone

(1) Power on the drone and place it on a flat surface. The lights on the drone will blink as it searches for a signal from the transmitter. Be sure head facing forward and the tail facing towards the pilot.

(2) Turn on the transmitter, push the left control stick fully forward, wait for a Di to sound, then pull the stick fully rearward, and wait for a second Di. and the lights on the drone stop blinking when the transmitter and the drone have paired successfully.

Calibrate the Gyro

(3) After pairing, press the “Gyro Calibration” key. The LED lights of the drone will blink for 2-3 seconds. When the light turns solid, calibration is completed. (To ensure a stable flight, after pairing the drone and after a crash, we recommend the pilot calibrate the gyro. And please do not calibrate the gyro while flying)

Take Off the Drone

(4) After pairing and calibration, press down the one key take off/landing button, the drone will fly to the height of 80cm automatically. Then you can pull the left control stick up or down to adjust the height of the drone. Press the take off/landing button again, the drone will land automatically. After landing, wait for the propellers to stop spinning. Power OFF the transmitter Before powering OFF the drone. This will ensure that no signals are accidentally sent by the remote, reducing the chance of injury. After this is done, it is safe to pick up and power off the drone.

Flight Controls

Rise And Fall Control.

Push the left control stick – up or down and the drone will rise or fall.

Forward And Backward Control.

Push up or down on the right control stick and the drone will fly forward or backwards.

Turn Left And Right.

Push the left control stick left or right and the drone will rotate to the left or to the right.

Left Wing And Right Wing Control.

Push the right control stick left or right and the drone will fly to the left or to the right.

Setting Trim & Countering Drift

If the drone keeps drifting leftwards when hovering, press the right side-fly trimmer to adjust until it gets balanced.

If the drone keeps drifting rightwards when hovering, press the left side-fly trimmer to adjust until it gets balanced.

If the drone keeps flying backwards when hovering press the forward trimmer to adjust until it gets balanced.

If the drone keeps flying forwards when hovering press the backward trimmer to adjust until it gets balance.

Even after the drone is calibrated, it may show a tendency to drift while airbore. Adjusting the trim will help counter this effect and allow better control of the drone. But it will not entirely eliminate it. Air currents and other factors may still cause slight drift while airbome.

Altitude Hold

This drone is equipped with Altitude Hold function meaning this drone will hover steadily in the air.
During flight, altitude hold function allows you to release the throttle joystick and maintain its height, without descending to the ground.

One Key Rotation/ One Key Spin

Short press the spin button, the drone will spin in a anticlockwise direction(A). And short press again to exit the spin mode(A). Long press the spin button, the drone will spin in a circles(B). And long press again to exit the spin mode(B). You can use the left control stick to adjust the height of the drone while in spin.
NOTE: Before you press the spin button, please make sure you fly the drone at least 8 feet away from any objects.

Speed Setting

How Fast

Press the Speed button on the remote to change the drone’s speed.
-Low: Provides smooth and predictable control of the drone. The remote will chime once to indicate the low speed setting.
-Medium: The drone will move and respond faster to all control inputs. The remote will chime twice to indicate the medium speed setting.
-High: Highest setting for maximum performance. The remote will chime three times to indicate the high speed setting.
Note: The 3 speed modes can only be cyclically changed in this order : low speed – medium speed -high speed – low speed.

Emergency Stop

Note: The emergency stop function can be only used in case of emergency during the flight to avoid any of damage or injury.
For any reason, if you need to stop the drone, press the “Emergency Stop” button or pull the left joystick down to the lowest, the drone will stop the propellers from spinning. Be sure the ground is clear of any objects as this will command the rotor to shut down and crash land.

3D Flip Mode

Before attempting a flip, be sure that there is enough clear space around the drone, ideally 9-10 ft. in all directions. It is not recommended to attempt to flip around or through any obstacles, as this may result in unintended damage.
Press the Flip button to activate Flip Mode, then move the Right Control Stick in any direction and the drone will perform a flip in the same direction Press the Flip button again to deactivate without performing a flip.

Caution: the drone will perform these maneuvers best with a fully charged battery.

Headless Mode

NOTE: Do not use the Headless Mode until you totally comprehend the instructions For Use. Flying in Headless Mode without sufficient experience might result in loss or damage to the device.

1. Place the drone in front of the pilot before pairing the drone to the transmitter. Make sure the head of the drone faces forward and the tail faces towards the pilot.
2. After pairing and calibration, press the Headless Mode button to enter Headless Mode function. A beep will be heard from the transmitter, indicates that drone is in headless mode.
3. Press the headless mode button again, you will hear a beep which indicates the drone exits the headless mode.
4. Under Headless Mode, the forward direction is the direction the pilot faces when the pilot pairs the drone with the transmitter.

Please make sure the pilot to stay in the same orientation as the drone head faces when the drone takes off.
It is very important that the pilot does not change the direction or orientation he or she faces, otherwise the drone and transmitter will lose connection, causing controls to not perform as desired.
Please use Headless Mode and One Key Return function after you totally comprehend these functions; otherwise, it may result in the loss and/or damage of the drone.

One Key Return

Please avoid using this feature when the drone is near to the pilot, to avoid injury.

   Wrong Track
Right Track

With a press of the One Key Return button, the drone will return towards the original direction of take-off.
You can rotate the right joystick in any direction to retake control of the drone and cancel the One Key Return Function.
It is recommended to use the return function when headless mode is activated.

NOTE: Please use one key return function after you totally comprehend these functions; otherwise, it may result in the loss and/or damage of the drone.

Trouble Shooting

• Poor contact between power plugs.
