The Holy Stone Hs720G drone has gained popularity among hobbyists and beginners for its user-friendly features and reliable performance. One of its most notable features is the return-to-home (RTH) function, designed to enhance safety and ease of use during flights. This article presents a comprehensive flight test focused on evaluating the effectiveness of the RTH feature in various scenarios.

Understanding the Return-to-Home Feature

The RTH feature allows the drone to automatically return to its takeoff point when triggered. It can be activated manually via the remote control or automatically if the drone loses connection or detects low battery levels. The Holy Stone Hs720G’s RTH system uses GPS technology to navigate back accurately, aiming to prevent crashes and loss of the drone.

Flight Test Setup

To evaluate the RTH feature, several flight scenarios were conducted in an open outdoor environment. The tests included:

  • Manual activation of RTH during flight
  • Automatic RTH triggered by signal loss
  • RTH activation during low battery warning
  • RTH with GPS signal interference

Test Results and Observations

Manual Activation

When manually activated via the remote, the drone responded promptly. It ascended slightly before turning around and flying back along the GPS-guided path. The drone maintained a steady course and landed accurately within a few meters of the takeoff point.

Automatic Activation Due to Signal Loss

During the test, when the drone lost connection beyond the effective range, the RTH feature was triggered automatically. The drone initiated a safe return route, navigating around minor obstacles and landing precisely at the original takeoff location. This demonstrated the reliability of the GPS system under typical interference conditions.

Low Battery Activation

The drone’s low battery warning prompted an automatic RTH. The drone ascended to a safe altitude, then turned back efficiently. It successfully returned and landed without incident, confirming the system’s effectiveness in conserving power and preventing crashes.

GPS Signal Interference

In scenarios with intentional GPS signal interference, the RTH feature experienced delays and occasional deviations. While the drone still attempted to return, its accuracy was slightly reduced, emphasizing the importance of a clear GPS signal for optimal RTH performance.

Conclusion

The Holy Stone Hs720G’s return-to-home feature proved to be highly effective in most tested scenarios. It responded quickly to manual commands and automatically activated during signal loss and low battery conditions, with precise landings. However, GPS interference can impact its accuracy, highlighting the importance of flying in areas with minimal signal disruption. Overall, the RTH system enhances the safety and usability of the drone, making it a valuable feature for both beginners and experienced pilots.
