The Holy Stone HS720E is a popular drone among beginners and hobbyists. Known for its affordability and user-friendly features, it offers a range of capabilities suitable for those new to drone flying. This article provides a detailed overview of the HS720E, highlighting its features, performance, and suitability for various users.
Design and Build Quality
The HS720E boasts a foldable design, making it compact and easy to transport. When folded, it measures approximately 6.8 x 4 x 2.2 inches, and when unfolded, it extends to about 13.2 x 8.4 x 2.2 inches. Weighing 495 grams, it feels sturdy and well-built, capable of withstanding minor impacts. However, due to its weight, it requires registration with aviation authorities in some countries, such as the FAA in the United States.
Camera Capabilities
Equipped with a 4K Ultra HD camera, the HS720E captures videos at 30 frames per second and photos at a resolution of 3840 x 2160 pixels. The camera features Electronic Image Stabilization (EIS) and utilizes a Sony sensor to reduce blurring and ensure video quality. The lens offers a 130° field of view and can tilt between -90° to 0°, allowing for versatile shooting angles. While the EIS helps in stabilizing footage, the absence of a physical gimbal means that video stabilization may not be as smooth as drones equipped with such hardware.
Flight Performance
The HS720E is powered by brushless motors, which are more efficient and quieter than brushed motors. This contributes to a smoother flight experience and better durability. The drone offers two speed modes: a slower mode suitable for beginners and precise shots, and a faster mode for more dynamic flying. It can reach speeds up to 22 mph in the faster mode.
Battery Life and Charging
The drone comes with two 2800mAh batteries, each providing approximately 23 minutes of flight time, totaling up to 46 minutes. However, charging each battery can take between 5 to 7 hours, which is relatively long. The inclusion of two batteries allows users to swap them out and continue flying without immediate recharging.
Intelligent Flight Modes
The HS720E offers several intelligent flight modes that enhance user experience:
- Follow Me Mode: The drone automatically follows the user, ideal for capturing activities like hiking or biking.
- Waypoint Flight: Users can set a predefined path for the drone to follow, allowing for automated flight paths.
- Point of Interest: The drone circles around a specific object or location, useful for dynamic shots.
- Auto Return Home: The drone automatically returns to its takeoff point when the battery is low or the signal is lost, adding an extra layer of safety.
GPS and Stability Features
The HS720E is equipped with GPS positioning and optical flow sensors, ensuring stable flight both indoors and outdoors. These features help maintain the drone’s position, making it easier for beginners to control. The GPS also enables the Auto Return Home function, providing peace of mind during flights.
Remote Control and Connectivity
The drone’s remote controller operates on a 5GHz frequency, offering a control range of up to 3277 feet (approximately 1 kilometer). The First Person View (FPV) transmission range is about 1640 feet, allowing users to view real-time footage on their smartphones. However, the controller uses AA batteries instead of a rechargeable battery, which may be less convenient for some users.
Pros and Cons
Pros:
- Affordable price point, making it accessible for beginners.
- 4K camera with EIS and Sony sensor for quality footage.
- Brushless motors for efficient and quiet operation.
- Intelligent flight modes enhance user experience.
- Foldable design and carrying case for portability.
Cons:
- Lack of a physical gimbal may affect video stabilization.
- No obstacle avoidance system, requiring careful navigation.
- Long battery charging time.
- Controller uses disposable AA batteries.
User Feedback
Many users appreciate the HS720E for its ease of use and value for money. The drone’s stability and intelligent flight modes are often highlighted as beneficial for beginners. However, some users note that the video quality, while good, does not match that of higher-end drones, and the lack of obstacle avoidance requires more cautious flying.
Conclusion
The Holy Stone HS720E is a commendable choice for those new to drone flying or looking for an affordable option with a range of features. Its 4K camera, intelligent flight modes, and stable flight performance make it suitable for casual photography and recreational use. While it lacks some advanced features found in more expensive models, such as a physical gimbal and obstacle avoidance, it offers excellent value for its price point. For beginners and hobbyists seeking a reliable and user-friendly drone, the HS720E is worth considering.
