When you press the reset switch down in GPS mode, the aircraft records the current coordinates and flies in a horizontal circle around the centre with these coordinates.

BIND TRANSMITTER AND RECEIVE

When delivered, the transmitter and receiver are already connected to each other. If the connection must be re-established, please proceed as described below.

1. Press and hold the camera button and the power button on the remote control. You will hear a continuous beep.
2. Switch on the helicopter by pressing the on/off button on the battery. The yellow LED on the aircraft indicator will flash.
3. Make sure that the helicopter and the remote control are not more than 50cm apart.
4. The remote control will emit two consecutive beeps and the display will show the reception power, indicating that the binding was successful.
5. If the binding is not successful, please repeat the above steps and try again.

Note: After successful frequency matching, the indicator light will be displayed accordingly depending on the current remote control switch position, please refer to the light indication.

1. Fast flashing yellow LED: Self-test of the helicopter.
2. Illuminated red LED: Helicopter is in visual positioning mode.
3. Slow flashing green LED: GPS Signal search and positioning.
4. Illuminated green LED: GPS positioning.
5. Illuminated yellow LED: manual attitude mode.

WARNINGS & EXCEPTIONS

1. Slow flashing red LED Level 1 low power.
2. Fast flashing red LED: Level 2 low power.

Note: After binding the helicopter with the remote control, different operating modes are displayed depending on the position of\ the switches on the remote control.

GYRO CALIBRATION

NOTE: During calibration, make sure that the motor lock switch is in the locked position! After successful binding, please push the left lever of the remote control (MODE2) into the lowest left corner and the lowest right corner with the right lever for 2 – 3 seconds as shown in the picture. The yellow LED on the helicopter flashes. As soon as the green LED lights up permanently, the calibration is complete.

Make sure the helicopter is on a level surface for take-off, otherwise the gyro calibration will be affected, and recalibration will be required. If initialisation cannot be completed or if yaw occurs in manual flight mode, the gyroscope must be recalibrated. When calibration is complete, the indicator light will be displayed according to the current switch position of the remote control.

COMPASS CALIBRATION

NOTE: During calibration, make sure that the motor lock switch is in the locked position!
Place the helicopter on the ground. In Mode 2, pull the left lever to the lower left corner and the right lever to the upper right corner. The yellow LED flashes, indicating that the helicopter is in compass calibration.

Now hold the helicopter by the rotor head at a height of about one metre and turn the fuselage by hand at least 360° around the rotor shaft. Then hold the helicopter with the tail pointing upwards and rotate it at least 360° around its own axis. As soon as the yellow flashing LED changes to green, the calibration is complete.

NOTE:
Do not calibrate in areas with strong magnetic fields, such as magnetic mines, buildings with underground metallic reinforcement (e.g., concrete). Please do not carry magnetic materials when calibrating and do not do so near large metal parts.

Method 2: After landing, pull both levers to the lower, inner corner. The engine stops immediately.

Pull the throttle lever down for 3 seconds.

Pull both levers down inwards.

FIRST FLIGHT

If you are not familiar with the remote control, take a few minutes to learn how to use it.

FLIGHT CONTROL INTERFACE DIAGRAM

NOTE:
When using S-BUS receivers or other systems, some functions are not supported, and errors may occur. Please check the system carefully before operating the model with it.

FLIGHT MODES

The remote control has a GPS stabilisation mode, an optical positioning mode and the manual flight mode, which can be selected by switching a switch. The middle position of the SWD-8 switch is the GPS stabilisation mode including the geomagnetic module. Due to the exact positioning and the sensor-based stabilisation, the helicopter flies very smooth and stable. The maximum tilt angle is 25°, the maximum flight speed is five metres per second. When the SWD-8 switch is in the up position, the optical position sensor is active. This setting is suitable for terrain with no or poor GPS signal. The maximum flight altitude in this mode is 6m. The maximum speed is 1m per second in L mode and 2m per second in H mode. The manual flight mode can be activated via the SWB-6 switch. When this is in the down position, the mode is active. Only use this mode if you are an experienced pilot or if there are problems with GPS coordination or other sensors and you need to perform an emergency landing.

NOTES ON THE OPTICAL POSITION SENSOR

Please always pay attention to your surroundings. The visual system only plays a supporting role under limited conditions andcannot replace human judgement and control. Always be sure to maintain control of the model and the controls. The sensor system scans the objects through a lens. The limited height is 6 metres, please avoid launching on a building roof or similar. If you fly over the roof of a building, the lower system will fail, and the helicopter will drift. In this case you should fly the model back immediately or switch to GPS stabilisation mode immediately. The sensor system is not able to detect surfaces and environments without texture features. Low or excessive light intensity may cause malfunction. The system will not function in the following scenarios.

1. Pure coloured surfaces such as pure black, pure white, pure red, pure green, etc.
2. Surface with strong reflections or mirroring.
3. Water surface or transparent objects.
4. Surface of moving objects e.g., people, bushes and grasses blown by strong wind etc.
5. Scenes with intense and rapid changes of light.
6. Extremely dark or light surfaces of objects.
7. The surface of materials that have a strong absorption or reflection effect on infrared light.

EXPERT INVERT MODE

In GPS mode and at a flight altitude of more than 10 metres, press the Mode button and the helicopter will enter inverted flight preparation, flying according to the direction of the lever on the back. The inverted flight works in the opposite direction as the normal flight (lever up, helicopter down, lever forward, helicopter backward). Press the MODE button again and press the lever, the helicopter turns around and continues flying normally.

AUTO COMING HOME
The helicopter has an auto-home function. If the GPS signal is good, the starting point remains stored in the system. If you set the SWD-8 switch to the lowest position, the helicopter flies back to the starting point and lands. It also does this automatically if the battery power is insufficient or if the connection between transmitter and receiver is lost. When the helicopter is in Coming Home mode, the icon appears on the remote-control display a sound is heard.

RETURN POINT

After switching on the helicopter, the first satellite search takes a little longer. Wait until the indicator light changes from a slowly flashing green light to a steady green light, the GPS symbol and the number of satellites appear on thedisplay of the remote control and the remote-control beeps before the motor can be unlocked in GPS mode. At this time, the helicopter will also store the coordinates of the current take-off point, which will be recorded as the return landing point.

NOTE: If the number of satellites on the transmitter screen is not sufficient, it means that the GPS quality is not good. If there is no GPS sign on the transmitter screen, the GPS mode cannot be enabled for launch. When launching in visual sensor mode or manual setting mode, the launch point is recorded at the position where satellites are found. This involves a risk, do not use the auto home function in this case.

STRAIGHT RETURN

When the user takes the initiative to control the Smart Return, the remote control emits three beeps, and the display shows the return symbol. The model returns in a straight line as follows:

1. The helicopter registers the return point.

2. The Smart Return is triggered.

3. The model brakes first and then turn to the return point to begin the return flight.
   A. If the return distance is > 15 metres, the helicopter will point the nose at the return point. If the current altitude is more than 10 metres, it will return directly; if the altitude is less than 10 metres, it will climb to 10 metres altitude and return.
   B. If the return distance is 3-15m, the helicopter will adjust direction and head for the return point at the current altitude; if the current altitude is <5m, it will climb to 5m and then return.
   C. If the return distance is <3m, the helicopter will land directly.

4. The helicopter will automatically fly back to the return point and then start landing

SMART LOW POWER RETURN

To avoid unnecessary hazards due to insufficient battery power, the model intelligently determines whether the current power is sufficient based on the flight position information. If the power is only sufficient to return or to trigger the level 1 low voltage protection, the model will automatically return. If low power is detected in Level 1, the aircraft will position itself within a 25 metre radius of the take-off point, at an altitude range of 20 metres as the flight limit, and transition to hover. At this point you can control the model to fly within this boundary until protection level 2 occurs. The model lands at the return point and switches off.
Note: When entering protection return, the remote control emits an alarm and the RX power indicator flashes. In the protection return state, the return of the model cannot be aborted. If the aircraft does not exceed 25 metres and an altitude of 20 metres before entering protection level 1, it can be controlled to fly within these limits. In the event of a low power return, it is possible to go directly to low power level 2 and return directly to landing.
NOTE: In visual positioning mode and manual mode, the helicopter will not go into intelligent protection return mode and perform the landing on the spot. Please pay close attention to the flight mode and performance of the model.

FAILSAFE RETURN

If the connection with the remote control is interrupted for more than 3 seconds (the model icon and the RX power icon in the centre of the remote- control display disappear), the helicopter will return. When the connection to the remote control is re-established and the signal continues (the model icon and RX power appear on the remote-control display), the helicopter completes the return flight and hovers to wait for the operation command.

ONE-BUTTON-LANDING
When you press the auto-landing button, the helicopter lands on the spot and does not return to the starting point. The remote control can steer the model during the landing process. During the process, you can push up the throttle of the remote control to cancel the landing command or you can cancel it by pressing the button again. At this point the aircraft is hovering and waiting for control commands.

ROUND FLIGHT
Switch the SWA-5 switch down. The model saves the current coordinates and starts to perform a horizontal round trip with these coordinates as the centre point. Switch the switch back or move the aileron/elevator lever to end the round trip.

PROPELLER PITCH SETTING

If the user replaces a servo or other important accessories, the propeller pitch may change, and the flight stability may be reduced. Please follow the steps below to adjust it.

1. The remote control is connected to the receiver of the helicopter.
2. Slide the SWC-7 switch on the remote control down to lock the motors. Slide the SWA-5 switch down eight times continuously to enter the propeller pitch setting. The remote-control display will show only the aircraft and channel pattern.
3. Press and hold the camera button and a beep will sound, then all servos will go into servo referencing.
4. Adjust the corresponding servo with the joystick until the aircraft cross is level and the propeller angle is 0 degrees. Then slide the SWC-7 switch on the remote control up, the propeller pitch adjustment is complete.

Note: An experienced person is required to adjust the propeller pitch.
