Pre-Flight Safety Inspection

Check the helicopter carefully before takeoff:

• Inspect main blades, tail blades, body, and landing skids for damage or distortion. Replace with genuine Fly Wing RC parts if necessary.
• Ensure flight control linkages and fuselage are securely fixed. Verify the GPS unit is horizontally placed on the tail boom, aligned straight behind the main mast. The H1 Unit should be fixed firmly on double-sided foam pads, with its arrow pointing towards the direction of travel.
• Check power levels for both the helicopter and transmitter. After powering on the transmitter, turn on the helicopter and confirm it passes the self-inspection test (rotor head and swashplate move regularly).

Flight Environment Requirements

• Do not fly in adverse weather conditions like strong winds (over 10m/s), rain, snow, or fog.
• Choose open areas free from tall buildings. Steel structures can affect compass function and block GPS signals.
• Avoid areas with high voltage cables, radio stations, mobile phone towers, or Wi-Fi sources to prevent signal interference.
• Exercise caution when flying above 6000 meters, as cold temperatures and thinner air can reduce battery and motor performance.

Flight Operation Requirements

• Fly within your visual line of sight (VLOS).
• Keep clear of rotating blades and the motor.
• Activating the stop switch during flight will cause the helicopter to fall; use only in emergencies.
• During flight, avoid using mobile devices that might interfere with helicopter operation (e.g., making calls, sending messages).
• Do not operate the helicopter under the influence of alcohol or drugs.
• Return the helicopter promptly when a low power warning appears on the transmitter.
• If the radio signal is restored during an automatic return, you can regain manual control.
• After landing, power off the helicopter first, then the transmitter, to prevent signal loss.
• When using GPS Autopilot or Return Home, be prepared to take manual control via the 3D mode switch for emergencies. The helicopter remains in Auto GPS mode until the flight stop button on the transmitter is activated.
• Maintain manual control at all times; do not solely rely on GPS. GPS functionality may be limited in certain modes or environments, affecting precise landing or braking.

Use naked-eye observation to judge flight conditions and set appropriate flight and return altitudes based on the environment.

GPS Mode Unlock / Take Off (Example using Mode 2)

1. Turn the transmitter motor run switch to the stop position, set the mode switch to GPS, and observe the H1 light flashing yellow.
2. Move the helicopter to an open outdoor area free of trees and buildings. Power on the transmitter and wait for the GPS satellite signal search.
3. After a few minutes, the H1 light will change from flashing yellow to solid green, indicating successful positioning.
4. Unlock by holding the specified switch/button for about 5 seconds until the H1 flight control unit flashes green light. [Image Description: Close-up of transmitter controls and the H1 unit on the helicopter.]
5. While the green light is flashing, move the stop switch to the run position. The helicopter motor will start, and the light will turn solid green. Repeat the unlock procedure if necessary.
6. Once the helicopter rotor head speed is stable, push the throttle stick upwards to take off. Raise the helicopter slightly, then release the throttle stick to hover.

⚠️ Important Notes:

• Do not stop the motor during flight, as this will cause a crash, unless in special circumstances to minimize injury (e.g., preventing collision with a crowd).
• The helicopter cannot take off if the low power alarm is critical.
• After starting the motor, the blades rotate at high speed and are dangerous. Maintain a safe distance and keep the helicopter away from crowds, buildings, trees, or obstructions.
• After landing, power off the helicopter first, then the transmitter.

Unlock / Take Off in 3D Mode (Example using Mode 2)

1. Set the motor run switch to stop position and the mode switch to 3D position.
2. Move the helicopter to an open outdoor area without trees and buildings. Power on; the H1 flight control light should be solid blue.
3. Unlock by holding the specified switch/button for about 5 seconds until the flight control light flashes blue. [Image Description: Close-up of transmitter controls and the H1 unit on the helicopter.]
4. While the blue light is flashing, move the motor switch stick to the run position. The helicopter motor will start. Push the throttle stick upwards to take off.

⚠️ About 3D Mode: Switching from GPS to 3D mode while airborne will cause the helicopter to descend rapidly. This mode is dangerous for novices and can lead to crashes. Experienced pilots can manage pitch control after switching to 3D mode.

Home Mode

For Home Mode (one-key return, low power return), ensure good GPS satellite signal before takeoff and clear airspace around the takeoff point.

• Smart Return: Set the switch to HOME; the helicopter will return automatically. Switch to GPS mode to terminate the return flight.
• Low Power Return: The system automatically initiates return and landing when power is low. Ensure the helicopter's current distance is within its remaining power range. During low power return, the helicopter will ascend to 15 meters before returning, uncontrolled by the operator. If obstacles are present, the auto-flight must be terminated.

Ways to Stop Low Power Return:

• To stop low power return, flick the switch to HOME, then to GPS. Manual control is restored after landing. Power off the helicopter and transmitter. The helicopter will not auto-return until powered off.

Users can adjust the return voltage or disable the low power return function. It is recommended to set the return voltage between 3.65V and 3.75V, as this affects flight duration and return distance. When the transmitter signal is normal, landing position can be controlled during return.

Compass Calibration

Compass performance can be affected by strong electric, magnetic, and electromagnetic fields, leading to abnormal readings and flight accidents. Regular calibration ensures optimal compass function.

Calibration Precautions:

• Do not calibrate in areas with strong magnetic/electric fields or near large metal objects (e.g., magnetic ore, parking lots, reinforced buildings).
• Avoid carrying ferromagnetic materials (keys, watches, speakers) during calibration.
• If calibrated indoors, recalibrate outdoors to account for magnetic field differences.
• Move the helicopter away from potential steel material interference before calibration.

Calibration Procedure:

Perform calibration in an open space. For detailed instructions, visit www.flywingrc.com/video/. Calibration is performed using parameter adjustment software.

1. Download the software from www.flywingrc.com/software/.
2. Connect the flight control to a computer via a USB Type-C data cable.
3. Select the correct COM port (usually not COM1) and click "Connect".
4. Navigate to the sensor calibration option, enable "Learning mode", and click "Start calibration".
5. The rotor will rotate 360° upright and 360° inverted.
6. Perform head-up and head-down vertical rotations of 360 degrees.
7. Repeat the process until the calibration progress bar completes, indicating success.

[Image Description: Screenshot of the calibration software interface showing sections for "Sensor", "Magnetometer Calibration", "Learning mode", "Start calibration", "Cancel", "Voltage", "Low Battery Protection", and a progress bar.]
