two poles aligned correctly, as shown in Figure 2. After installation, please
refit the battery cover.
Flight Environment
- Please select open and spacious with no tall buildings surrounding the site for the flight.
- Do not use the product in elements, such as strong winds (above level 4), heavy snow or rain, or fog.
- Please keep far away from obstructions, crowds, high-voltage wires, trees water bodies, etc.
- Please do not use the product in places where electromagnet (such as communication
base stations, cell towers, or high voltage stations) is an influencing factor to avoid being
interfered with.
Pre-flight Inspection
Before the flight, please check
- If the batteries for the aircraft and the remote controller have sufficient power.
- If the propellers are correctly installed without damage.
- If the propellers work well after the aircraft has been powered on.
Power On
Turn on the power of the aircraft and the remote controller, as shown in the
picture.
Pair the Remote Controller with the Aircraft
- Put the aircraft on stable ground and ensure the front of the aircraft and the remote controller are faced in the same direction as shown in the picture(except in headless mode).
- Turn on the aircraft and then the remote controller.
- Toggle the left joystick towards the highest position and then the lowest position, and the aircraft’s indicator will turn from blinking to solid with the remote controller beeping twice, indicating the pairing has been successful.
If it fails to pair after a long period, please turn off the aircraft and remote controller first, and repeat the steps above.
Basic Operations
After pairing, please follow the 2 steps below before starting the motor.
Calibrate the Headless Mode
As shown in Pic 1, toggle the left and right joysticks towards the lower left
corner, and the aircraft’s indicator will blink slowly, indicating the
calibration has been successful. Please refer to the “Headless Mode” section
in “Advanced Operations” for more details.
Calibrate the Gyro
Put the aircraft on the level ground or surface to start with, which helps the
aircraft succeed in taking off. If placed on uneven or even rough surfaces or
ground during the process of calibration, the aircraft may yaw in a certain
direction, which cannot be fine-tuned, after takeoff. This may result in
damage to the motor or control loss. As shown in Pic 2, toggle the two
joysticks towards the lower right corner, and the aircraft’s indicator will
blink quickly, indicating the calibration has been successful.
Notes: If the aircraft collapses or falls to a great extent, the gyro may
be out of control, thus producing an impact on the actual flight. If the above
happens, please re-calibrate the gyro.
Notes: When you see the propellers come to a stop, there is a chance that the left joystick has not been toggled instead the motor has been powered off. So not until you confirm the motor has been powered off, please do not get close to the aircraft or use your hands to touch the motor, otherwise, it may result in injuries.
Fine-tuning
To clear all the fine-tuning settings, please exit the fine-tuning mode and long press the No.4 button of the remote controller until the remote controller delivers a long beeping sound and the aircraft’s indicator lights blink twice before turning solid, indicating the process has been successful.
Flips & Rolls
Advanced Operations
Speed Switch
Press down the left joystick to switch the speeds with low and high modes
available.
The remote controller beeps once at low speed and beeps twice at high speed.
Notes: Low-speed mode will be activated by default each time you turn off
the aircraft and the remote controller and then turn on.
Headless Mode
Calibrate the Headless Mode: After pairing, press “Calibrate the Headless
Mode” on the remote controller and the aircraft’s front (the side facing the
camera) is front with other directions including back, left, and right
relative to your direction.
Enter Headless Mode: Long press the NO. 5 button, and the aircraft’s indicator
turns from solid to blinking, indicating it has entered headless mode. Long
press again, and the aircraft’s indicator turns back to solid, indicating it
has exited headless mode. In Headless Mode, when you toggle the right joystick
upward, the aircraft will fly forward regardless of where it is positioned.
And when you toggle the right joystick downward, the aircraft will fly
backward, and so on.
Examples : When the aircraft is placed as indicated in Pic 2 after
pairing, you can calibrate the Headless Mode and the aircraft will fly forward
in the direction the arrow indicates being its front.
Please activate Headless Mode when the aircraft:
- Flies as indicated in Pic 1 by toggling the right joystick upward to let the aircraft fly along the direction the arrow indicates.
- Flies as indicated in Pic 2 by toggling the right joystick downward to let the aircraft fly along the direction the arrow indicates.
- Flies as indicated in Pic 3 by toggling the right joystick to the left to let the aircraft fly along the direction the arrow indicates.
- Flies as indicated in Pic 3 by toggling the right joystick to the right to let the aircraft fly along the direction the arrow indicates.
Notes : This feature helps beginners to recognize the orientations of the aircraft and control it to return.
Control Loss Protection
- Control loss protection will be triggered when the aircraft loses control signal and starts to descend slowly and vertically in places where it loses control signal.
- This helps reduce the risks of getting lost or crashes.
- The feature may be triggered when:
- The remote controller is powered off at a sudden.
- There are obstructions between the remote controller and the aircraft.
- The remote control signal has been interfered with by electromagnetic waves.
- The flight distance goes beyond the effective signal transmission range due to wind force or inertia.
Emergency Stop
When the aircraft loses control or an emergency happens (like being
intertwined by branches, wires, or hairs), tightly press the No.6 button on
the remote controller for 2 seconds to activate the emergency stop. When the
aircraft is in the air and the emergency stop has been turned on, the aircraft
will drop or even get destroyed and threaten the crowds, cattle, or objects
underneath. So please be cautious when you activate this function.
Alternatively, you can toggle the left joystick downward for 2 seconds to
finalize regular descent.
Troubleshooting
If it fails to take off, please
- Check if you have turned on the aircraft and the remote controller.
- Check if the batteries for the aircraft and the remote controller have sufficient power. And If the batteries are of low voltage due to long-time suspension. If so, please recharge the battery for the aircraft and replace the battery for the remote controller.
- Turn off the aircraft and the remote controller and then turn them on before pairing again.
If the aircraft vibrates, please
- Check if the propellers are broken or out of shape. If so, please replace them.
- Check if the protective guards are fixedly installed or out of shape, which results in an imbalance of the aircraft or the friction between the propeller contacts against the protective guard.
- If you have detached the aircraft, please check if the screws are properly fixed.
If the aircraft always yaws in one direction, please
- Fine-tune the direction with the fine-tuning function.
- Put the aircraft on the level surface or ground and proceed to “Calibrate the Gyro” again before the next flight.
