5. Setup

5.1. Battery Charging

The quadcopter is powered by a 1S 240mAh 3.7V LiPO battery. Use the included USB charging cable to charge the battery. Connect the battery to the USB charger, then plug the USB charger into a compatible USB power source. The charging time is approximately 45 minutes to an hour.

5.2. Transmitter Batteries

The transmitter requires 4 AAA batteries (included). Install them into the battery compartment on the back of the transmitter, ensuring correct polarity.

5.3. Binding Procedure

To establish communication between the transmitter and the quadcopter:

1. Turn on the transmitter.
2. Connect the quadcopter's battery. The quadcopter's lights will flash.
3. Wait for the indicator light on the quadcopter to turn solid green. This indicates successful binding.

5.4. Accelerometer Calibration

Before each flight, calibrate the accelerometer on a flat and level surface to ensure stable flight and minimize drifting. Refer to the transmitter's display screen for calibration prompts.

6. Operating Instructions

6.1. Basic Flight Controls

• Ascend: Slowly push the left (throttle) stick up.
• Descend: Slowly pull the left (throttle) stick down.
• Rotate Counter-clockwise: Push the left (rudder) stick to the left.
• Rotate Clockwise: Push the left (rudder) stick to the right.
• Fly Forward: Push the right (elevator) stick up.
• Fly Backward: Pull the right (elevator) stick down.
• Fly Left (Strafe): Push the right (aileron) stick to the left.
• Fly Right (Strafe): Push the right (aileron) stick to the right.

6.2. Expert Mode

To enter Expert Mode, short press the right (elevator/aileron) stick. This mode increases the sensitivity and responsiveness of the controls, allowing for more agile maneuvers.

6.3. Roll Mode (Flips)

To perform a roll:

1. Long press the left (throttle/rudder) stick.
2. While in roll mode, operate the right (elevator/aileron) stick in the desired direction (forward, backward, left, or right) to execute a flip.

6.4. Headless Mode

To enter Headless Mode, short press the left (throttle/rudder) stick. In Headless Mode, the quadcopter's orientation is relative to the pilot, making it easier to control without needing to track the front of the drone.

6.5. Fine-Tuning

Use the fine-tuning buttons on the transmitter to make small adjustments to the quadcopter's flight characteristics if it drifts in any direction. Press the trim button opposite to the direction of drift.

7. Maintenance

7.1. Propeller Replacement

In case of a crash or damage, propellers may need to be replaced. The package includes spare propellers. Carefully remove the damaged propeller and install a new one, ensuring it is securely fitted. Using a U-wrench (not included) can help remove propellers without damaging the motor shaft.

7.2. General Care

Keep the quadcopter clean and free from dust and debris. Store it in a cool, dry place away from direct sunlight when not in use. Avoid exposing the electronics to moisture.

8. Troubleshooting

• Quadcopter Drifts: Recalibrate the accelerometer on a flat surface. Use the fine-tuning buttons on the transmitter to correct minor drifts.
• Not Flying Level: Check for bent or broken propellers and replace if necessary. Ensure all motors are securely attached. Perform accelerometer calibration.
• Short Flight Time: The battery may not be fully charged or may be nearing the end of its lifespan. Ensure the battery is fully charged before use. Consider replacing the battery if performance does not improve.
• No Response from Quadcopter: Ensure the transmitter and quadcopter are properly bound. Check that both the transmitter and quadcopter batteries are charged and correctly installed.
