OVERVIEW

1 . THE INSTALLATION OF BATTERY OF REMOTE CONTROL DEVICE

Open the battery cover on the back of remote controller. lnsert3X1 .5V “AA” batteries in accordance with the instructions on battery box. (Battery should be purchased separately, old and new or different types of batteries shouldn’t be mixed.)

2. THE BATTERY CHARGING OF FL YING DEVICE

1. Plug the USB charger into the USB interface of the computer or other chargers connected with USB, and then turn on the power;
2. Remove the battery from the aircraft, and then connect the battery plug with the socket on the USB charger for charging;
3. During the charging process, the indicator light is red, and after the battery is fully charged, the indicator light is blue Or off.

3. Replace the blades

Each paddle of flying device are not same, on each blade is marked with “A:’ or “B”. When installing of paddle, please perform correctly installation according to the corresponding labels as shown in figure below. When paddle is not correctly installed, flying device can’t take off, roll over, and skating fly.

4. THE OPERATION AND CONTROL OF FL YING DEVICE

Note: Aircraft before takeoff must first correct the frequency. Aircraft lights flashing when A the correction, the correction is completed after the lights lit. ln avoidance of uncontrollable, …,_ when flying device moves, it always needs to pay attention on the operating level carefully.

In the process of operation, the flying device may loss a little power, thus it needs to add power to march. ( . The direction of aircraft head)

The remote control will make a drip sound when the plane is low on electricity.
If the aircraft falls or lands, it is recommended to re calibrate it before taking off again.

5. TAKE OFF OPERATION

1.Simultaneously push the handle downwards and outward to correct, and simultaneously push the handle downwards and inward to unlock.

2. Press the unlock button once, then press the takeoff button once, and then ress the aircra .
3. Press the unlocking button once t9 i:;>ush the oil valve for takeoff, and the airplane will slowly descend when the accelerator is pulled down.

The left control level controls the rising and falling of flying device.

The left control lever is to control turning left /right of flying device

The right control lever is to control turning marching/ retreating t of flying device V ‘

The right control lever is to control aircraft left and right side fly

6. CAMERA ANGLE CONTROL

The shooting angle of the PTZ camera can be adjusted through the up or down button of the remote control stegear. Shpwn in the figure

7. THE SETTINGS OF SENSITIVITYM

The aircraft can achive 3 mode of operation: low level (30°/o), intermediate level (60%) • high level(100%)
The Toggle aircraft “speed can conversachieve ion the swi3 tch” modes for of setting:op

Slide it, the buzzer on remote controller will beat twice = The aircraft moves at a medium speed (up to Slide it, the buzzer on remote controller will beat three times = The aircraft moves at a high speed (up to 61000%% );) .

Through this key, it can adjust sensitivity of flying device, the greater the sensitivity value  is, the faster the flying device response; conversely, it is slower.

8. THE ROLLING MODEL

The flying device can perform rolling flight of 360 degrees by following operation. In order to better implement rolling function, and endure flying device is kept five meters height above the ground, it is better to operate rolling in the process of rising up. In this case, the flying device can be kept with height after flying device performs rolling action.

1. Left side somersault: Click “mode of conversion”, and then push the right- control lever to left in maximum After the flying device rolls it is to turn control lever to the middle position

2 Right side somersault: Click “mode of conversion”, and then push the right- control lever to right in maximum. After the flying device rolls, it is to turn control lever to the miadle position.

3 Front somersault: Click “mode of conversion” and then push the right-control lever to front in maximum.
After the flying device rolls, it is to turn contro lever to the middle position.

4. Backward somersault: Click “mode of conversion”, and then push the right- control lever to backward in maximum. After the flying ‘device rolls, it is to turn control lever to the m10’dle position.

AFTER ENTERING INTO THE “ROLL MODE”, IF. ifHERE S O NEED OF. ROLLING F.UNCT ONS, THEN CLICK ifHE “MODE CONVERSION” KEY

9. HEADLESS MODE WITH ONE KEY BACKWARD

That is in flight, no matter what position the aircraft is, no matter what direction it’s attitude, as long as you dick on the headless mode button, automatic locking direction aircraft takeoff. When found in aircraft flight has left you very far when you could not tell the direction, then click on the headless mode key, you can not recognize the direction to control the aircraft return; return key or click the auto-off direction of the vehicle will automaticaly return.

1. of the code of the aircraft must head toward the front (o r rear headless mode and automatic mode opening direction will return disorder)
2. When you need to use the headless mode, click on the headless mode key, the vehide will automaticaly lock the direction of takeoff.
3. When you do not use the headless mode, then dick the headless mode button to exit the headless mode.

Warning: Try to choose less vision and pedestrians at the place with this aircraft, so as to avoid unnecessary losses!

10. OBSTACLE AVOIDANCE

The remote controller will also make a noise when the aircraft evades obstacles, a voidance No noise without avoiding obstacles.

Note: The glass is either transparent and the obstacle avoidance will fail when the ultraviolet ray is strong.

11.TRIMMING CONTROL

Press the right handle to star t the fine adjustment function, Push up for forward fine adjustment, push down for backward fine adjustment, push left for left fine adjustment, and push right.

12. TROUBLES SHOOTING DURING FLYING

| Situation| Cause| Way to deal
---|---|---|---
1| Receiver staus LED blinks continuously for more than 4 seconds after flight vehicle battery inserted.
No response to control input.| Unable to bind to transmitter.| Repeat the power up initializing process.
2| No response after battery is connected to flight vehicle.| 1. Power to transmitter and receiver.
2. Check transmitter and receiver voltage.
3. Poor contact on battery terminals.| 1. Turn on transmitter and ensure flight vehicle battery is inserted properly.
2. Use fully charged batteries.

4| Main rotor spins but unable to take off.| 1. Deformed main blades.
2. Flight vehicle battery depleted| 1. Replace main blades
2. Charge or replace with fully charged battery.
5| Strong vibration of flight vehicle| 1.Deformed main blades| 1. Replace main blades
6| Tail still off trim after tab adjustment, or inconsistent speed during left/right pirouette.| 1. Damaged tail rotors
2.Damaged taildrive motor| 1. Replace main blades
2. Replace the main motor
7| Flight vehicle stil wonders forward after trim adjustment during hover.| 1. Gyroscope midpoint not| 1. The boot willlift fine-tune the normalized neutral point, reboot
8| Flight vehicle stil wonders left/ right after trim adjustment during hover.| 1. Motor off
2. Cone loose| 1. Replace the motor

Product Usage Instructions

1. Reorient or Relocate Antenna

Ensure the antenna is properly oriented for optimal signal reception. If necessary, relocate the antenna to improve reception.

2. Increase Equipment-Recevier Separation

Maintain a sufficient distance between the equipment and the receiver to prevent interference. Ideally, increase the separation to minimize signal disruption.

3. Power Outlet Consideration

Plug the equipment into a power outlet on a circuit different from the one used by the receiver. This helps in reducing potential interference.

4. Consultation

If experiencing difficulties, consult with the dealer or a qualified radio/TV technician for assistance. They can provide guidance on resolving any operational issues.

Frequently Asked Questions (FAQ)

Q: What should I do if I encounter interference issues?

A: If you experience interference problems, try reorienting the antenna, increasing equipment-receiver separation, changing power outlets, or seeking assistance from a professional.
