5. Setup
5.1 Charging the Drone Battery
- Connect the drone battery to the USB charging cable.
- Plug the USB cable into a USB power adapter (not included) or a computer's USB port.
- The indicator light on the USB cable will show charging status (e.g., red light for charging, off when fully charged).
- Charging typically takes approximately 60-90 minutes. Do not leave unattended during charging.
5.2 Installing Drone Battery
- Ensure the drone is powered off.
- Locate the battery compartment on the underside of the drone.
- Carefully insert the fully charged battery into the compartment.
- Connect the battery connector to the drone's power port.
- Close the battery compartment cover securely.
5.3 Installing Remote Control Batteries
The remote control requires 3 AA batteries (included).
- Open the battery cover on the back of the remote control.
- Insert 3 AA batteries, ensuring correct polarity (+/-).
- Close the battery cover securely.
5.4 Propeller Installation/Replacement
Each propeller is marked with an 'A' or 'B'. Match the propeller type to the corresponding motor shaft on the drone. Incorrect installation will prevent proper flight.
- Identify the 'A' and 'B' markings on the propellers and drone motor arms.
- Gently push the correct propeller onto its motor shaft until it is secure.
- Ensure propellers spin freely without obstruction.
6. Operating Instructions
6.1 Pairing the Drone and Remote Control
- Place the drone on a flat, level surface.
- Turn on the drone by pressing its power button. The LED lights will flash.
- Turn on the remote control.
- Push the left joystick (throttle) all the way up, then all the way down. The drone's LED lights will stop flashing and remain solid, indicating successful pairing.
6.2 Gyroscope Calibration
For stable flight, calibrate the gyroscope before each flight.
- After pairing, ensure the drone is still on a flat, level surface.
- Push both joysticks down and to the right simultaneously for a few seconds.
- The drone's LED lights will flash rapidly and then become solid, indicating successful calibration.
6.3 Basic Flight Controls
- Take-off/Landing: Gently push the left joystick up to take off. Pull it down slowly to land.
- Ascend/Descend: Push the left joystick up to ascend, pull down to descend.
- Forward/Backward: Push the right joystick up to fly forward, pull down to fly backward.
- Turn Left/Right (Yaw): Push the left joystick left to rotate left, right to rotate right.
- Fly Left/Right (Roll): Push the right joystick left to fly left, right to fly right.
6.4 Special Features
- 360° Roll-Over: Press the 360° roll button on the remote, then push the right joystick in the desired direction (forward, backward, left, or right) to perform a flip. Ensure sufficient altitude before attempting.
- Headless Mode: Press the Headless Mode button. In this mode, the drone's orientation is relative to the pilot, regardless of the drone's front direction. Press again to exit.
- Speed Adjustment: The drone has multiple speed modes (e.g., low, medium, high). Press the speed button to cycle through the modes. This is useful for beginners to start with lower speeds.
7. Maintenance
