What the Holy Stone HS720 gimbal does
The Holy Stone HS720 uses a motorized gimbal to keep the camera level during flight and reduce shaking from wind, turns, and throttle changes.
If the gimbal is not working, the drone may still fly, but your video will appear tilted, jittery, or locked in one position.
This problem can come from simple setup issues, software calibration errors, or hardware damage inside the gimbal assembly.
The good news is that many HS720 stabilization problems can be diagnosed without opening the drone.
Common symptoms of a HS720 gimbal failure
Before troubleshooting, identify the exact behavior.
Different symptoms usually point to different causes.
- The camera stays stuck at one angle and does not level out.
- The gimbal jitters, vibrates, or makes small repeated movements.
- The camera tilts on takeoff and never recenters.
- Video looks shaky even though the drone is hovering normally.
- The app shows a camera feed, but the gimbal does not respond to tilt commands.
- The gimbal initializes briefly, then stops or drifts.
Why the Holy Stone HS720 gimbal not working issue happens
The HS720 gimbal depends on a mix of mechanical parts, sensors, power delivery, and app communication.
A failure in any one of those areas can disable stabilization.
1. Gimbal calibration is off
If the drone was handled roughly, transported without a case, or powered on while the gimbal was obstructed, the calibration can drift.
In that state, the motors may try to stabilize from the wrong baseline.
2. The gimbal is physically blocked
Dust, bent foam packaging pieces, a twisted camera ribbon, or a misaligned protective cover can prevent full movement.
Even a small obstruction can make the motor appear dead.
3. Firmware or app communication is interrupted
The Holy Stone app and drone firmware need to communicate correctly for camera and gimbal control.
A failed update, outdated app version, or poor phone connection can leave the gimbal unresponsive.
4. The drone has a loose cable or damaged connector
Inside compact drones like the HS720, a loose flex cable or connector can interrupt power or control signals to the gimbal.
This is more likely after a crash or hard landing.
5. The gimbal motor or sensor has failed
If the drone was dropped, struck, or stored with the gimbal under stress, one of the motors or internal sensors may have failed.
In that case, software fixes will not restore normal movement.
Step-by-step fixes for the HS720 gimbal
Work through the steps in order.
Start with the least invasive checks and move toward advanced troubleshooting only if needed.
1. Power down and inspect the camera assembly
Turn the drone off, remove the battery, and inspect the gimbal under good light.
Look for debris, tangled ribbon cables, signs of impact, or anything physically preventing movement.
- Make sure the camera is not pressed against the frame.
- Check for shipping foam or packaging residue left near the gimbal.
- Confirm the lens cover or protector is removed.
- Gently verify that the camera can move within its normal range.
2. Restart both the drone and the controller
A full power cycle can clear temporary communication faults.
Turn off the drone, controller, and app, then restart everything from scratch.
Reconnect only after the drone finishes its startup sequence.
3. Calibrate the drone on a level surface
Use a flat table or floor, away from vibration.
The gimbal and flight sensors both rely on a stable baseline, so a level surface matters.
- Place the drone completely still.
- Open the Holy Stone app.
- Run the available calibration or gyro setup process.
- Wait until the procedure finishes before touching the aircraft.
If the app offers a gimbal calibration option, perform that separately from the flight sensor calibration.
4. Check the app’s camera and tilt controls
Some gimbal problems are caused by app settings rather than hardware.
Open the camera interface and test whether tilt controls respond.
- Verify that the app is connected to the correct Wi-Fi or transmission link.
- Reset camera-related settings to default if available.
- Test the tilt slider or wheel to see whether the camera angle changes.
- Update or reinstall the app if it behaves inconsistently.
5. Update the drone firmware and mobile app
Firmware mismatches can cause the Holy Stone HS720 gimbal not working issue, especially after a partial update or app reinstall.
Use official Holy Stone resources only, and avoid interrupting the update process once it starts.
Before updating, charge the drone battery and your phone fully.
An update interrupted by low power can create a deeper software fault.
6. Inspect for crash damage
If the drone recently hit the ground, tree, wall, or water, assume a mechanical issue until proven otherwise.
Gimbal components are delicate and can lose alignment from even a minor impact.
Signs of impact damage include:
- Cracked camera housing
- Uneven camera hang angle
- Rattling inside the gimbal area
- Persistent vibration after power-up
7. Re-seat visible connectors only if you are experienced
If you are comfortable working on small electronics and the warranty is no longer a concern, you can inspect for loose connections.
Use caution, since ribbon cables and tiny connectors are easy to damage.
Do not force any cable into place.
If the connector looks torn, bent, or detached from the board, professional repair is safer than a DIY fix.
How to tell whether the problem is software or hardware
A software issue usually shows up as inconsistent behavior: the gimbal works after a restart, then fails later, or the app controls stop responding while the camera hardware still moves during startup.
A hardware issue is more likely when the gimbal never initializes, feels mechanically stuck, or makes repeated grinding or clicking noises.
A simple test is to watch the gimbal immediately after powering on.
If the camera does a short initialization movement and then freezes, the motors may be receiving power but not completing calibration.
If it does nothing at all, the problem may be power, wiring, or a failed control board.
When the Holy Stone HS720 gimbal needs service
Some repairs are not practical without replacement parts or specialized tools.
Contact Holy Stone support or a qualified drone repair shop if you see any of these signs:
- The gimbal motor feels seized or overheats quickly.
- The camera cable is visibly torn.
- The drone fails calibration after multiple clean resets.
- The gimbal shakes violently every time it powers on.
- The drone was exposed to water, sand, or a hard crash.
If the aircraft is still under warranty, avoid disassembling it further.
Opening the drone can affect warranty coverage and complicate replacement claims.
How to prevent future gimbal problems
Preventive care matters because the HS720 gimbal is sensitive to impact and storage pressure.
Keeping the camera protected reduces the chance of recurring faults.
- Use the original gimbal protector during storage and transport.
- Do not power on the drone while the gimbal is physically restricted.
- Store the drone in a dry case away from dust and heat.
- Land gently to reduce shock on the camera assembly.
- Keep firmware and the Holy Stone app updated from official sources.
- Recalibrate after crashes, transport, or major software updates.
Useful checks before every flight
A quick preflight inspection can catch a gimbal issue before it affects your footage.
- Confirm the camera hangs freely.
- Look for error messages in the app.
- Test tilt control before takeoff.
- Verify that the drone initializes normally on a flat surface.
- Inspect the gimbal after each rough landing or hard stop.
If the Holy Stone HS720 gimbal not working issue appears repeatedly, the fastest path to a stable fix is to narrow down whether the cause is calibration, software, wiring, or physical damage.
Once you identify the category, the next repair step becomes much easier to choose.
