6 Flight

This section details flight operations and environment requirements.

6.1 Flight Environment Requirements

Do not fly in severe weather (strong winds, snow, rain, or fog).
Choose an open area free of obstacles. Buildings, mountains, and trees can interfere with compass and GPS signals. Fly in an open space with at least a 33ft (10m) radius free of obstructions. Flying above 49ft (15m) is suggested to avoid ground obstacles and signal interference.
Keep the aircraft within line of sight and clear of obstacles and crowds. When flying over water, maintain a distance of at least 9.8ft (3 meters) from the surface.
Avoid areas near high-voltage power lines, communication towers, or transmission towers, as control signals can be disrupted.
Fly at altitudes below 9842ft (3000 meters) to ensure the barometric altitude hold function operates correctly.
When GPS is active, the aircraft achieves stable hovering, smart return-to-home, and smart flight functions. Without GPS, these functions will not work, and the aircraft may drift.

6.2 Pre-Flight Checklist

Ensure the remote controller, smart flight battery, and mobile device have sufficient power.
Make sure the aircraft's arms are fully extended.
Ensure the battery compartment cover is securely fastened and the smart flight battery is properly installed.
Check that propellers are not damaged, worn, or deformed, and that there are no foreign objects tangled in them. Ensure they are securely installed.
Make sure GPS is enabled to avoid losing signal, and fly outdoors in an open area.
Check that the data cable connecting the remote controller and mobile device is securely installed.
After powering on, verify that all four motors start normally and their speeds are consistent.
Ensure the camera is clean.
If replacing parts, always use original manufacturer components. Using non-original parts can pose a risk to safe operation. Refer to the accessories support page in the appendix for details.

6.3 Pairing Remote Controller with Aircraft

Please refer to section 4.4.4.

6.4 Connect the Data Cable

This section describes how to connect your mobile device to the remote controller.

Select the appropriate data cable (Type-C to Micro-USB, Type-C to Type-C, or Type-C to Lightning).
Use the data cable to connect the remote controller to the mobile device.
Open the Gleesfun Fly App and allow popup permission requests.
Enter the operating interface. If you see the aircraft's live video feed, the connection is successful.

⚠️ When connecting the data cable, ensure the cable plug is securely installed. On some phones, the phone case may prevent proper seating, causing poor contact and failed data transfer.

The Type-C to Type-C data cable is stored inside the remote controller when shipped.

⚠️ Please set the USB options correctly when prompted: On Android devices, select 'Transferring Files / Android Auto'; on iPhones, select 'Trust'. On some Android devices, USB settings are hidden in Developer Options. Enable Developer Mode and change 'Default USB Configuration' to 'File Transfer'. The remote controller does not support fast charging for mobile devices. Check your mobile device's battery level before use.

6.5 Compass Calibration

If the aircraft experiences unusual behavior or loss of control, compass calibration may be necessary to prevent sensor interference.

Calibration Steps:

Extend the aircraft's four arms and place it on a flat, open surface.
Turn on the aircraft and the remote controller, and ensure they are paired successfully.
Short press the compass calibration button on the remote controller; the aircraft's lights will start flashing quickly.
Open the app to see the calibration guide animation.

Horizontal Calibration: Follow the app's instructions: Hold the aircraft at a height of 1 meter above the ground, rotate it horizontally 2-3 times until you hear a beep and the app indicates it's time to begin vertical calibration.

Vertical Calibration: Hold the aircraft at a height of 1 meter above the ground with the camera facing up. Rotate the aircraft vertically 2-3 times until you hear a beep and the animation on the app interface stops. This indicates calibration is complete, and the aircraft's lights will return to their original state.

⚠️ Before flying, monitor the compass interference level in the app. If it approaches 120, it indicates excessive interference; manually calibrate or choose a different location. If it exceeds 180, the aircraft will automatically enter compass calibration. If the aircraft exhibits uncontrolled behavior (spinning, erratic flight), it may indicate incorrect calibration or interference. Promptly land and perform manual calibration. When calibrating, extend arms and ensure the aircraft is at a height of 3.3ft (1m) above the ground to avoid magnetic interference.

6.6 Gyroscope Calibration

Gyroscope Calibration Steps:

Ensure the aircraft is placed on a level surface with enough space below the camera.
Push both the left and right control sticks to the '5 o'clock' position simultaneously.

Aircraft's lights will flash quickly, indicating automatic horizontal calibration is in progress. When the app calibration prompt disappears and the lights return to their original state, calibration is complete.

⚠️ If the aircraft shows tilt or instability during flight, land it on a level surface to perform gyroscope calibration. When resetting, ensure the aircraft is placed on a flat, level surface.

6.7 Starting/Stopping the Motor

6.7.1 Starting the Motors

Method 1: Push the joysticks to the 5 o'clock and 7 o'clock positions simultaneously. Once the motors start, immediately release the joysticks.

Method 2: When the motors are not running, press and hold the takeoff/landing button on the remote controller to start them.

6.7.2 Stopping the Motors

Push the throttle stick to the lowest position and do not release it until the motor stops.

6.8 One-key Takeoff / Landing

6.8.1 One-key Takeoff

Method 1: After starting the motors, press and hold the takeoff/landing button on the remote controller. The aircraft will take off automatically and hover at a distance of 4.9ft (1.5m) from the ground.

Method 2: Tap the one-key takeoff icon in the App, then swipe right in the pop-up window. The aircraft will take off automatically and hover at a distance of 4.9ft (1.5m) from the ground.

6.8.2 One-key Landing

Method 1: After takeoff, press and hold the takeoff/landing button on the remote controller. The aircraft will land to the ground and stop the motors.

Method 2: Tap the one-key landing icon in the App, then swipe right in the pop-up window. The aircraft will land to the ground and stop the motors.

⚠️ During the aircraft's descent, pushing the throttle stick up on the remote controller will cancel the automatic landing.

6.9 Return to Home (RTH)

The G11PRO aircraft features a Return to Home (RTH) function in GPS mode when it has a strong GPS signal. This function returns the aircraft to the last recorded home point and lands it automatically. There are three types of RTH: Smart RTH, Low Battery RTH, and Lost Signal RTH.

6.9.1 Home Point Definition

GPS	Description
Home Point	? During outdoor flights, when the GPS signal icon first shows three bars or more, the takeoff location will be recorded as the return-to-home point. During the flight, if you land at a new location, the new takeoff point will become the latest return-to-home point, and the return-to-home function will direct the aircraft to this latest point.

6.9.2 Smart RTH

When you need the aircraft to return home automatically, press the Smart Return-to-Home button ? on the remote controller or tap the return-to-home icon ? on the app interface to initiate automatic return.
During the return-to-home process, pressing the button or tapping the icon again will cancel the return. After canceling Smart RTH, you can regain control of the aircraft.
During the Smart RTH process, you can maneuver the aircraft to ascend or descend to avoid obstacles. You can also press the RTH button again to cancel the return.

⚠️ After clicking the return button, the aircraft will return to the destination in different ways depending on flight distance, altitude, and whether return altitude is set in the App. If flight distance is within 16.4ft (5m), the aircraft lands directly. If flight distance is greater than 16.4ft (5m) and return altitude is NOT set: If altitude is below 65ft (20m), it rises to 20m and returns. If altitude is above 65ft (20m), it returns from current altitude. If flight distance is greater than 16.4ft (5m) and return altitude IS set: If altitude is lower than set altitude, it rises to set altitude and returns. If altitude is higher than set altitude, it returns from current altitude. The aircraft is not equipped with obstacle avoidance; make reasonable judgments and set appropriate flight/return altitude.

6.9.3 Low Battery RTH

When the smart flight battery is too low or there is not enough power to return home, land the aircraft as soon as possible to avoid damage or other dangers.
To prevent dangers due to insufficient battery power, the Low Battery RTH function will be automatically triggered when the aircraft battery power is low.
Situations:
- First-level low battery: Aircraft returns to Home Point and hovers. It can then continue to fly within a 98ft (30m) radius at a height of 98ft (30m).
- Second-level low battery: Aircraft lands directly.
When the aircraft's battery is low, the remote controller emits a sound. It beeps slowly at First-level Low Battery and rapidly at Second-level Low Battery.

⚠️ Pay attention to flight altitude when the battery is low. Avoid hitting obstacles due to low flying altitude when returning with second-level low battery. Remaining power after returning relates to return distance, wind speed, and wind direction. When the aircraft is low on battery and returning, you cannot cancel the return. You can use the remote controller stick to avoid obstacles.

6.9.4 Lost Signal RTH

If the remote controller's battery is low, turned off, or lost signal for 10 seconds, the aircraft will enter automatic return-to-home mode and return to the Home Point.
If the remote controller reconnects during RTH and you wish to cancel, press the RTH button to cancel.

Lost Signal RTH process:

Record Home Point (refer to section 3.4.1).
Trigger RTH (by low battery of remote controller, signal loss, etc.).
After triggering RTH, the aircraft adjusts its nose direction and starts to return home.
The aircraft automatically flies to the Home Point, then starts to land, and completes the return.

⚠️ When out of control, the aircraft cannot avoid obstacles. When the GPS signal is weak, the aircraft cannot return to home automatically.

6.10 Smart Flight (Route Planning, GPS Follow, Fly Around, Cruise Control)

During surrounding flight, the pilot can adjust the surrounding radius using the joystick (range: 16ft (5m) to 328ft (100m)). Pushing the joystick down increases radius; pushing up decreases it.
By default, the aircraft performs surrounding flight counterclockwise. The pilot can change direction by pushing the directional joystick left or right.

How to Exit:

Tap the ? icon again to cancel Fly Around.

⚠️ If flight altitude is lower than 16ft (5m) when Fly Around is activated, the aircraft will rise to 16ft (5m). The flying speed of the surrounding radius depends on the radius itself; a larger radius means faster speed.

6.10.4 Cruise Control

The aircraft automatically flies at a constant speed according to the current flight action. This function requires GPS mode with a strong GPS signal.

How to Start:

Set desired auto-flight distance and altitude. Fly the aircraft to an altitude above 49ft (15m) (unavailable below 49ft (15m)).
Keep toggling the left or right joystick to operate the aircraft (forward, backward, ascent, descent), then press the remote controller's one-key takeoff/landing button ✈️.
Release the joystick; the aircraft will fly automatically according to your action (e.g., pushing the right joystick forward makes it fly forward automatically).
During cruise control, you can continue to use the joystick to adjust the aircraft's direction and altitude. Repeat steps 2 and 3; the aircraft will automatically fly based on your last joystick input.

How to Exit:

Method 1: During Cruise Control, pressing the one-button takeoff/landing button ✈️ on the remote controller without operating the joystick will cancel cruise control.

Method 2: Tap the ✈️ icon on the App to exit.
