Setup
1. Battery Charging and Installation
The drone comes with two intelligent rechargeable batteries. Ensure both batteries are fully charged before use. Use the provided USB charging cables to charge the batteries. Insert the charged batteries securely into the drone's battery compartment.
2. Remote Control Setup
The remote control features a phone holder that can be adjusted to fit your mobile device. Power on the remote control by short-pressing the power button. The remote control and drone will automatically connect once both are powered on and in close proximity.
3. App Installation and Connection
Download and install the "HK66 DRONE FLY" app on your mobile device. After powering on the drone and remote control, open your mobile phone's Wi-Fi list and connect to the Wi-Fi network named "HK66DRONE_XXXXXX". This establishes the FPV real-time transmission link.
4. Calibration
Proper calibration is crucial for stable flight. Perform the following calibrations before each flight and after any crash:
- Compass Calibration: Press the compass calibration button on the remote, or access the HK66 DRONE FLY app, navigate to "GO TO FLY" -> "Setting" -> "Calibrate". Follow the on-screen instructions to complete the calibration.
- Gyro Calibration: Place the drone on a level surface with its front pointing forward. After connecting the drone and remote, move both the left and right joysticks of the remote controller to the 7 o'clock position simultaneously. This initiates gyro calibration, which helps the drone fly more steadily.
Operating Instructions
Basic Flight Controls
- One-Tap Take Off/Landing: Press the designated button on the remote control for automatic take-off or landing.
- Altitude Hold: The drone maintains a stable altitude, allowing for easier control and clearer aerial photography.
- Headless Mode: In Headless Mode, the drone's orientation is irrelevant to the control inputs. Press the headless function button on the remote for approximately 4 seconds to activate. Press again to exit.

Advanced Flight Modes (GPS Enabled)
The HK66 Drone utilizes GPS positioning for enhanced flight stability and intelligent features:
- GPS Auto Return-to-Home (RTH): The drone will automatically return to its take-off point under conditions such as low battery, lost signal, or when commanded via the remote control.
- Waypoint Fly (Trajectory Flight): Draw a flight path on the HK66 DRONE FLY app interface, and the drone will follow the designated route. It is recommended to draw straight lines or simple arcs for initial attempts in open areas.
- Circle Fly (Point of Interest): This intelligent flight mode allows the drone to automatically orbit a designated subject, keeping it centered in the camera's view for dynamic footage.
- Follow Me: Using the GPS position from your smartphone, the drone will follow you at a set distance, capturing your movements.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your drone:
- Cleaning: Gently wipe the drone's body and camera lens with a soft, dry cloth after each flight to remove dust and debris.
- Propeller Inspection: Regularly check propellers for any signs of damage (cracks, bends). Replace damaged propellers immediately using the provided spare blades and screwdriver. Ensure propellers are installed correctly (A and B types).
- Battery Care: Store batteries in a cool, dry place. Do not overcharge or fully discharge batteries. If storing for extended periods, charge them to approximately 50-60%.
- Motor Inspection: Ensure motors are free from obstructions. Avoid flying in sandy or dusty environments that could damage the motors.
Troubleshooting
If you encounter issues, refer to the following common solutions:
- Drone Unstable/Drifting: Perform Gyro Calibration as described in the Setup section. Ensure the drone is placed on a level surface during calibration.
- GPS Not Locking/Poor Positioning: Ensure you are flying in an open area with a clear view of the sky. Perform Compass Calibration as described in the Setup section. Avoid areas with strong magnetic interference.
- No FPV Feed/App Connection Issues: Verify that your mobile device is connected to the drone's Wi-Fi network ("HK66DRONE_XXXXXX"). Restart the app, drone, and remote control. Ensure your phone's Wi-Fi is enabled and not connected to other networks.
- Short Flight Time: Ensure batteries are fully charged. Check for any obstructions on propellers or motors that might increase power consumption.
- Drone Not Responding to Remote: Ensure both the drone and remote control are powered on and properly paired. Re-pair if necessary by following the initial connection steps.
