When charging, the red indicator light of the product does not light, indicating that charging is in progress, and the charging saturation indicator lights up. Charging time is about 60 minutes.

As the product is a high-end product, the design only supports the use of computers or chargers less than 3.7V for charging. It is strictly prohibited to use other non-standard chargers to charge the battery!

WARNING ⚠️

If you do not want to play this quadcopter, disconnect the module battery from the aircraft.

Attention:

1. Make sure the voltage of the adapter fits the local electricity supply.
2. The charging plug will overheat while overcharged. Please stop charging immediately for it could cause serious damage to the battery.
3. Do not leave the battery aside when charging.
4. When the aircraft has just finished flying, the battery temperature is higher. It is best to wait for about 30 minutes until the battery is cooled before charging the lithium battery, otherwise the battery will be damaged.
5. Recharge the battery 30 minutes later after flying, because the battery temperature could be too high when flying and charging immediately could damage the battery.
6. Do not throw the battery into fire in consideration of safety.
7. Do not short circuit the battery. Do not leave the battery together with tiny medal parts in consideration of safety.

OPERATIONAL APPROACH

Descending ⬇️: When you push down the left lever (throttle), the spinning speed of the main blades will decrease and the quadrocopter will descend.

Turn right ➡️: When you push the left lever (steering) to the right, the quadrocopter will turn to the right.

Turn left ⬅️: When you push the left lever (steering) to the left, the quadrocopter will turn to the left.

Forward ⬆️: When you push the right lever (rudder) upward, the quadrocopter will fly forward.

Backward ⬇️: When you push the right lever (rudder) downward, the quadrocopter will fly backward.

Left sideward fly ⬅️: When you push the right lever (rudder) to the left, the quadrocopter will fly sideward to the left.

Right sideward fly ➡️: When you push the right lever (rudder) to the right, the quadrocopter will fly sideward to the right.

NOTICE ?: If the rudder lever is not pushed during the flight and the aircraft is still flying sideways in the air, the rudder fine-tuning button can be adjusted.

Caution ⚠️: When the quadrocopter ascends to 30cm high, it will be affected by the blade vortex made by itself, and become unstable. This is "ground effect". The lighter the quadrocopter, the greater the effect.

A diagram shows the aircraft inclining to the left. Text indicates: When the aircraft inclines to the left in flight, press the right fine-tuning button (button 9) until the aircraft is balanced.

A diagram shows the aircraft tilted to the right. Text indicates: When the aircraft is tilted to the right during flight, press the left spin button (key 10) until the aircraft is balanced.

A diagram shows the aircraft hovering and moving backward. Text indicates: When the aircraft is hovering, the fuselage moves backwards, pressing the forward trim button (key 8) until the aircraft does not move backwards.

A diagram shows the aircraft hovering and moving forward. Text indicates: When the aircraft is hovering, the fuselage moves forward, and the back spin button (key 7) is pressed until the aircraft does not move forward.

READY TO FLY

1. Unfold the quadcopter and place it on a horizontal position, then open up the power switch on the quadcopter. When the indicator lights flash, it means that the quadcopter goes into the flight standby mode.

Note ?: The antenna of the transmitter must be aligned the tail of the quadcopter.

The blades of each part of an airplane are different. Each blade is marked "2/3" or "1/4". When installing the blade, please install it correctly according to the corresponding label as shown below. When the blades are not installed correctly, the aircraft will not be able to take off, flip or throw.

Diagrams show blade installation with labels 1/4 and 2/3, indicating FRONT (camera) and TAIL.

FLIGHT OPERATIONS

1. Turn on the power switch (key 11). Push the left joystick (accelerator) to the highest point and then reset to the lowest point. When the light on the quadcopter becomes non-flashing, it indicates that the frequency is successful, push the left lever up and the aircraft starts in place.
2. Press and hold this button (key 1) for adjustment. The quadcopter's light stops flash and always light up, it means that compass adjustment successfully.

3D Flips and Rolls Flight

When the basic functions can be skillfully operated, you can play some adventurous tumblings. Flying the quadrocopter above the ground more than 3 meters, hovering, then push the tumbling button (key 11) on the controller. At this moment, when you can hear a beep from the controller, please push the direction panel. If you push forward, the quadrocopter will tumble forward; if you push backward, the quadrocopter will tumble backward. Every time you want to complete a tumble, you need to push the tumbling button. Continuous tumbling can be done if familiar.

Diagrams show: Forward Turning, Backward Turning, Left Turning, Right Turning.

Headless Mode instructions

Since the flight direction is consistent with the operating direction of the controller, there is no need to worry about too far to recognize the flight direction of the quadrocopter. So that the operation is more convenience and easier (Figure 1).

Headless Mode Operation:

When starting up and adjusting frequency, the controller should directly facing the tail of the quadrocopter (Figure 2). In normal flight, you can hear a beep when you push the headless mode button (Refer to page 2 "Parts of the controller"), that means the quadrocopter is already on headless mode and the navigational light is flashing. When you push the headless button again, you can hear a beep again, that means the quadrocopter drop out of the headless mode. In headless mode, the quadrocopter should stay directly in front of the controller.

When you push the direction lever forward, that means flying forward. When you push the direction lever backward, that means flying backward. Push to the left means left side flight; push to the right means right side flight.

ONE KEY AUTOMATIC RETURN FUNCTION

When quadrocopter flies too far, we can call the quadcopter back by one key automatic return function.

Operational Approach

When the aircraft flies too far, the one key automatic return function can help to recall the quadrocopter (Refer to page 2 "Parts of the controller"). In flight, you can hear a beep when push the one key automatic return button, then the aircraft will enter one key return mode and fly back automatically. And you can remove the return mode by handling the lever randomly.

CAUTIONS:

One key automatic return function only can work when you use it at the place you turned it on.
