Names of parts of the helicopter

Wind blade installation diagram

Unscrew the screw and remove the fan blade.

  Note: The fan blade is printed with A, B. Please install it correctly according to the instruction, otherwise it cannot take off.

Loosen the screw, open the two fan blades and the connecting parts, and remove the fan bladesfor replacement. (when A fan blade is broken, replace A, and so do to B fan blade, error in replacement will cause that it can’t take off)

Lithium battery installation

Align the battery with the card slot under the helicopter and push it into the battery holder.

Check after installation to ensure that the battery is installed in place.

Lithium battery charging instructions

Push in the direction indicated by the arrow.

Remove the battery.

Disconnect the power supply, and plug the charger into the power socket. When the battery is charging, the red indicator will be always on and it will be off when it is fully charged. The charging time is about 2 hours.

• This product is equipped with a built-in lithium battery. Please pay attention to the following safety precautions in use.
• Do not hit or beat the surface of hard objects with the battery.
• Do not immerse the battery in water, and store the battery in a dry place.
• Only use the charger that comes with the product.
• Do not leave battery alone when charging.
  

Note: If the helicopter are not in flight, please unplug the battery to prevent battery discharge. If the connector remains connected, it may cause excessive discharge due to long-term power consumption.

Name of each part of the remote control

Remote control battery installation

How to install the battery: Open the battery cover on the back of the remote control, and correctly insert 3 AAA alkaline batteries (batteries must be purchased separately) according to the electrode sign of the battery box. (see Figure)

Note:

1. The positive and negative poles and the positive and negative poles of the battery box must be identified when inserting the battery, and error is not allowed.
2. Do not mix old and new batteries.
3. Do not mix different types of batteries.
   

Environmental requirements before flight

Please fly in an open outdoor environment with no rain or snow and wind less than Grade 3. Please stay away from crowds, trees, wires, tall buildings, airports and signal towers when flying. Do not fly in places with weak signals.

Preparation instructions before flight

 The helicopter/remote controller must be fully charged or it cannot take off!

Turn on the side switch of the helicopter, the LED light on the helicopter flashes.

Turn on the remote control (step 1), the indicator flashes, push the throttle slick up (step 2) and then pull ii down to the bottom (step 3), the indicator of the remote control is always on, and so is the body light, which means frequency is successfully matched.

Horizontal calibration operation

After the helicopter is successfully frequency matched, place the aircraft on a fiat ground, short press the calibration button the remote control beeps, and the helicopter light will first flashes quickly and then will be always on, which means the level calibration is completed (Figure 1 ).

Note: The calibration must be done by placing the helicopter on a horizontal surface .

One-key take-off

When the level calibration is completed, long press the one-key take-off function button ‘¾ of the remote control (Figure 2), the helicopter blades will start to rotate, and then push the throttle stick of the remote control, and the helicopter will start to take off. When the one-key take-off function button is pressed again in the flight, the helicopter will descend slowly .

Manipulation method

Up| When the left joystick (throttle) is pushed up, the main rotor speed increases and the helicopter rises.|
---|---|---
Down| When the left joystick (throttle) is pushed down, the main rotor speed slows down and the helicopter descends.|
Turning| When the right joystick (steering rudder) is pushed to the left, the helicopter nose turns to the left. When it is pushed to the right, the helicopter nose turns to the right.|
Forward| When the right joystick (steering rudder) is pushed up, the helicopter nose is downward. The helicopter moves forward.|
Backward| When the right joystick (steering rudder) is pushed down, the helicopter nose is  upward. The helicopter moves backward.|

Special prompt

If the direction control stick is not pushed during flight, and the helicopter is still spinning in the air, at this time, the rudder fine-tuning button can be adjusted until it stop spinning.

When the helicopter nose rotates counterclockwise, I ig htly press the 1 right fine-tuning button CD until the helicopter does not rotate.|
---|---
When the helicopter nose rotates clockwise, lightly press the left fine-tuning button 2 until the helicopter does not rotate.|

Note: When the helicopter is at a position 30cm from the ground, the helicopter will be affected by the overcurrent of its own blades and become unstable, causing the aircraft to deflect to one side, which is called “ground effect response”. When the weight of the helicopter is lower, the influence of the ground effect response is greater.

Flight practice

After enough practice, try the following flight practice.

Fixed point rotation (direction rotation)

Keep going forward-turn left-forward-turn left-forward-turn left, practice flying a square pattern, practice repeatedly, and gradually practice flying a circle.

Landing at a designated place (fixed-point landing)

(“8” pattern flying)

1. Put the on/off engine in the “NO” position
2. The battery is not inserted correctly according to the electrode instructions.| 2. Check and make sure that the battery is inserted in accordance with the pas tive and negative poles indicated in the battery box.
3. The battery runs out| 3. Replace with new batteries
Remote control is not available| 1. Frequency matching is not yet done| 1. Please refer to 9.2
2. Too fierce wind| 2. Do not fly in windy conditions. Wind will restrict the aircraft or hinder your flight control.
The helicopter cannot fly higher| 1. Rotor rotation speed is too slow| 1. Push the power joystick up
2. The helicopter is not fully charged| 2. Fully charge the helicopter
The helicopter landed soon| 1. Pull the power joystick back too soon| Slowly pull back the power joystick to let the helicopter land slowly
2. The helicopter battery runs out| 2. Please charge the helicopter

Precautions

1. When the power of the remote control or helicopter is insufficient, the remote control distance will be affected and the distance will be shorter.
2. If the helicopter’s power is insufficient, the flight altitude is insufficient or the takeoff is difficult.
3. If the helicopter is damaged and deformed, please repair it in time. In severe cases, for example, when the rotor is broken or damaged, do not fly, otherwise it will cause injury.
4. If you do not use it for a long time, please take out the battery of the remote control to avoid damage to the product caused by battery leakage.
5. Don’t let the helicopter crash or collide seriously at high altitude, this will damage the helicopter or shorten the life of the helicopter.
6. This model of airplane contains a variety of alloy parts. attention must be paid for children to avoid from cutting by the alloy parts when playing.
