5. If the binding process is unsuccessful, please repeat the above steps to rebind.

Helicopter Status Indicator Light Explanation:

1. Rapid yellow flashing: Aircraft self-checking. The aircraft should remain stationary until the self-check is completed.
2. Solid green: Downward visual optical flow mode. Limited to flying at a height of 8 meters.
3. Slow green flashing: Poor downward visual environment. Lower the flight altitude or change 4. the flying area.
4. Solid red: Manual flight mode. Exercise close attention when flying manually.
5. Slow red flashing: Low-level battery warning. Control the aircraft within visual range.
6. Rapid red flashing: Critical-level battery warning. The aircraft will initiate an automatic landing.

Gyroscope Calibration:
After successful binding between the aircraft and the remote control, perform the following steps to calibrate the gyroscope. On the remote control (MODE2), hold the left joystick in the upper corner and the right joystick in the lower corner as shown in the diagram for 2-3 seconds. During this time, the aircraft’s indicator light will flash yellow and then change to solid green, indicating that the calibration is com

During gyroscope calibration, it is important to place the aircraft on a level surface to ensure accurate flight. The gyroscope is already calibrated at the factory, so users do not need to calibrate it again unless they are unable to exit the initialization or if there is yaw drift in manual attitude mode. In such cases, recalibration is necessary. After successful calibration, the indicator light will provide prompts based on the current position of the remote control’s switch, as explained in the indicator light section.

Manual Motor Start/Stop:

Motor Start:
Perform the throttle stick action to start the motor. Immediately release the stick after starting the motor. Push the throttle stick upward by more than 50%, and the aircraft will take off.

Motor Stop:
There are two methods to stop the motor after it has started: Method 1: After the aircraft has landed, move the throttle stick to the lowest position and hold it for at least 3 seconds to stop the motor. Method 2: After the aircraft has landed, pull both joysticks inward simultaneously to stop the motor immediately. Release the sticks after the motor has stopped.

Helicopter Locking
Long press the lock button to hear two beeps for locking, and short press for one beep to unlock. Locking should not be performed while the aircraft is in the air, as it may cause the motors to stop and pose a risk of crashing.

First Flight:
If you are not familiar with FOB, please take a few minutes to familiarize yourself with its controls before attempting your first flight.

Notes on Downward Vision Mode

Please pay attention to the surrounding flying environment. The vision system only serves as an auxiliary function under limited conditions. It cannot replace human judgment and control. Users should constantly be aware of the surrounding environment during flight, maintain control over the aircraft through— out the entire flight, and take responsibility for their actions.

The downward vision system relies on the camera to lock onto objects below and limits the takeoff altitude to 8 meters. Please avoid taking off from rooftops or flying over rooftops, as it may cause the downward vision to fail, resulting in aircraft drift. In such cases, immediately fly the aircraft back or switch to manual stability mode.

The downward vision system cannot recognize surfaces without textured features and cannot function properly in environments with insufficient or excessive lighting. The following scenarios are where the downward vision
system cannot work

1. Solid color surfaces (e.g., solid black, solid white, solid red, solid green)
2. Surfaces with strong reflections or reflections
3. Water surfaces or surfaces of transparent objects
4. Surfaces of moving objects (e.g., above crowds, bushes, and grasses swaying in strong winds)
5. Scenes with rapidly changing lighting conditions
6. Surfaces that are exceptionally dark or exceptionally bright
7. Surfaces of materials that have strong absorption or reflection of infrared

Manual Mode Flight

Pressing the Manual Mode buttori will disable the optical flow flight mode. In this mode, the aircraft’s status indicator light will remain solid red, and the altitude restriction will be lifted. The maximum flight speed can reach up to 10 meters per second. Please closely monitor the aircraft and operate with caution. Pressing the throttle adjustment button on the remote control again will activate the optical flow mode, indicated by a solid green status indicator light on the aircraft

One-Key Landing
During flight, long-press the One-Key Landing button, and the aircraft will initiate a landing at its current position. While landing, the remote control can still be used to control the aircraft. Pushing the throttle up during the landing process will cancel the landing. Alternatively, pressing the One-Key Landing button again will cancel the one-key landing function.

Expert Inverted Flight Mode:
This mode is designed for 3D aerobatic inverted flight training and should be conducted in open outdoor areas with calm or light wind conditions, In manual mode, with the flight altitude above 9 meters, press the upper right One-Key Inverted Flight button. The remote control will emit two beeps. Quickly push the elevator stick forward or backward and immediately return it to the center position. The aircraft will automatically perform a 180-degree roll and enter inverted flight hover.In this mode, the helicopter’s control input is the same as that of a 3D helicopter (pushing the throttle stick up will make the aircraft descen)d, pushing the elevator stick forward will make the aircraft move towards the tail).

Pressing the One-Key Inverted Flight button again and quickly moving the elevator stick will transition the aircraft from inverted flight to normal flight mode, restoring normal flight behavior.

Inverted flight : Forwarder & Backwarder Roll Only. No For Left & Right!

Pitch Setting:
When users replace servos or other major components, it may alter the pitch setting. Correct pitch setting contributes to stable flight. Please follow the steps below for pitch setting. Long-press for two seconds for pitch setting.

1. Power on the aircraft and bind it with the remote control.
2. Long-press the lock button on the remote control to lock the aircraft with two beeps. Then long-press the pitch setting button to enter pitch setting mode with two beeps.
3. Use the joystick to adjust the corresponding servo until the aircraft’’s swash— plate is level and the rotor blade angle is O degrees. Then, short—press the lock button on the remote control to unlock with a beep, exit the pitch setting mode, and save the settings.
   **Note:** Pitch setting should be done under the guidance of an experienced individual. Incorrect pitch setting can result in reduced flight performance.

Common Troubleshooting:

aircraft is in gyroscope self-checking state.Please place the aircraft on a stationary and flat surface.
2| The aircraft tilts to one side and cannot hover after takeoff.| Place the aircraft on a level tabletop or surface and recalibrate the gyroscope.
3| The aircraft experiences severe shaking.| Check for damaged rotor blades and replace them with new ones. Inspect the main shaft and cross-axis for any
bending and replace them promptly.
4| The aircraft cannot be unlocked, and the indicator light flashes red rapidly.| The battery voltage is too low. Please fully charge the battery.
5| Unstable flight in strong wind conditions.| Fly in appropriate weather conditions. The aircraft is suitable for flying in wind conditions up to level 4.
6| No response from the helicopter after power on, slow flashing light.| Rebind the frequency. During rebinding, the aircraft should be placed horizontally.
7| Slow flashing green light in downward vision flight mode.| Ground environment may affect the performance of the downward vision system. Please test in a different environment.
8| No power-on sound when connecting power to the helicopter.| The speed controller may be faulty or the plug connection is poor. Replace the speed controller and inspect the plug for timely replacement.
9| Continuous beeping from the remote control during flight.| The aircraft voltage is low, triggering a level 1 alarm. Replace the AAA batteries in the remote control.
