Why the Holy Stone HS720 return to home not working issue matters
The return to home function is one of the most important safety features on the Holy Stone HS720, especially when signal is weak, battery is low, or the drone drifts far away.
When it fails, the problem is often tied to GPS readiness, compass calibration, takeoff habits, or controller settings rather than a single broken part.
This guide explains the most common causes of the Holy Stone HS720 return to home not working problem and walks through clear fixes you can try before assuming a hardware fault.
How the HS720 return to home feature is supposed to work
On the Holy Stone HS720, return to home depends on a stored home point, stable GPS lock, and a properly calibrated compass.
When triggered manually or by failsafe conditions, the drone should fly back to the recorded takeoff location and descend nearby.
That behavior only works well if the drone has enough satellite data to identify its position accurately.
If the home point was never set correctly, or if GPS conditions changed after takeoff, the drone may hover, descend, or drift instead of returning.
Common reasons the return to home function fails
GPS lock was not strong enough before takeoff
The most frequent cause is flying before the drone has enough satellites.
The HS720 needs a solid GPS connection before it can reliably record the home point.
If takeoff happens too early, return-to-home behavior may be inaccurate or unavailable.
- Wait for the app or controller to show strong GPS status.
- Confirm the drone has locked satellites before arming the motors.
- Do not launch from indoors, a garage, a car roof, or under trees.
The home point was never recorded correctly
Even with a visible GPS signal, the drone may fail to log home correctly if takeoff happens too quickly.
Some pilots assume the feature is active as soon as the drone connects, but the home point is usually set only after sufficient GPS stability.
If the drone returns to a point far from where it launched, or not at all, the stored home location may be wrong or incomplete.
The compass needs calibration
Compass data tells the drone which direction it is facing.
If the compass is miscalibrated, the HS720 may misjudge its heading and return in the wrong direction, wobble, or fail to initiate a proper return.
Compass problems are more likely after travel, crashes, or flying near metal structures, reinforced concrete, vehicles, or power lines.
Always calibrate in an open area away from magnetic interference.
The drone is in an unsuitable flight environment
Return to home performance depends on clean GPS and stable navigation.
Dense urban areas, reflective surfaces, heavy tree cover, electromagnetic interference, and weak satellite visibility can all degrade reliability.
- Avoid flying close to high-rise buildings.
- Keep away from large metal objects and parked vehicles.
- Do not rely on RTH in areas with poor sky visibility.
Battery level or altitude conditions are limiting the feature
If the battery is critically low, the drone may prioritize landing over a full return.
Likewise, if the drone is too low to clear obstacles, it may not climb high enough to execute a safe path home.
Some pilots also forget that return-to-home behavior is not the same as obstacle avoidance.
The HS720 may come back in a straight line or a simple pattern rather than navigating around trees, poles, or buildings.
Controller or app settings are not configured properly
On some flights, the return-to-home behavior can be affected by how the controller or app is configured.
If the RTH command is not mapped as expected, or if flight mode settings are interfering, the feature may seem broken when it is actually not being triggered correctly.
Check whether you are using the physical controller button, a dedicated app command, or a failsafe trigger, and confirm the drone responds to the intended input.
Step-by-step fixes for Holy Stone HS720 return to home not working
1. Power on in the correct order
Start with the controller, then the drone, and then the app if you use one.
This helps avoid sync issues that can affect status reporting and GPS behavior.
- Turn on the transmitter/controller first.
- Power on the HS720 on level ground.
- Wait for connection and GPS confirmation before takeoff.
2. Wait for a stable GPS lock
Before launching, give the drone time to acquire enough satellites and stabilize its home point.
Watch for the GPS icon or status prompt indicating readiness.
If the drone still reports weak GPS, move to a clearer outdoor location and try again.
3. Calibrate the compass in an open area
If the drone has not been calibrated recently, or if it has traveled a long distance since the last flight, recalibrate the compass.
Perform the calibration far from cars, concrete with rebar, wireless towers, and metal surfaces.
4. Reboot the drone and controller
Temporary software or connection errors can affect navigation logic.
Power-cycle both the drone and controller, then reconnect and verify satellite lock again before flying.
5. Test return to home at a safe altitude
Once the drone is stable and airborne, trigger RTH at a moderate altitude in an open area.
This helps verify whether the function is actually failing or whether it was previously blocked by conditions such as poor GPS or a low takeoff point.
6. Update the app and inspect firmware-related notices
If the Holy Stone app offers updates or prompts, install them.
Version mismatches between app, controller, and drone can sometimes affect command recognition or flight status feedback.
Even when firmware is not user-updatable, ensuring the app is current can improve reliability.
7. Inspect for physical damage
After a crash or hard landing, antenna connections, shell alignment, motor mounts, or sensor placement may be compromised.
If the drone also shows unstable hovering, erratic yaw, or poor GPS hold, physical damage may be contributing to the RTH issue.
How to tell whether the problem is user error or a real fault
The Holy Stone HS720 return to home not working issue is often caused by launch conditions rather than defective hardware.
If the drone fails only when GPS is weak, calibration is skipped, or the home point was rushed, the system is probably functioning as designed.
A deeper fault is more likely if the drone repeatedly ignores RTH commands in open-sky conditions, with a strong satellite lock, correct calibration, and a confirmed home point.
In that case, the navigation module, firmware logic, or controller linkage may need service.
Best practices to prevent return to home failures
- Fly only outdoors with a clear view of the sky.
- Wait for a full GPS lock before takeoff.
- Calibrate the compass after travel or after a crash.
- Keep the takeoff area free from cars, metal, and concrete reinforcement.
- Set a realistic RTH altitude high enough to clear nearby obstacles.
- Test RTH in an open field before relying on it near trees or buildings.
For pilots who fly the HS720 regularly, these habits greatly reduce the chance of an unexpected return-to-home failure.
They also improve overall flight stability, waypoint accuracy, and failsafe behavior.
When to contact Holy Stone support
If the return-to-home feature still fails after you have checked GPS, calibration, altitude, app behavior, and physical condition, contact Holy Stone support with flight details and symptoms.
Include whether the drone acquired satellites, whether the home point was confirmed, and whether RTH failed manually or during a failsafe event.
That information helps determine whether the issue is related to setup, environmental interference, or a hardware or software defect that may require repair or replacement.
