- Sticks not in the correct unlock position.

Push both joysticks to the inner–lower corners to unlock.

- Compass not calibrated / abnormal status.

Calibrate the compass before flight until the TX beeps and status is normal.

- GPS not ready for GPS mode.

Wait for solid GPS (outdoors). If flying indoors, long-press the GPS key to enter Attitude (ATTI) Mode.

- Low battery.

Recharge/replace the battery if the drone LED shows continuous red.

- Camera/gimbal cover still on.

Remove the cover before powering on.

- Drone not on a level surface during init.

Place it flat and wait for gimbal initialization.

- In compass calibration.

Finish calibration; the gimbal doesn’t work during it.

- Obstruction under the gimbal.

Ensure clearance or use a landing pad.

- Weak GPS (near buildings/trees/obstructions).

Fly outdoors in open areas with strong GPS.

- Compass interference (metal, lines, towers).

Land and recalibrate away from interference.

- Damaged/incorrect propellers.

Replace or reinstall props and check tightness.

- IMU not calibrated.

Calibrate the IMU per the manual before flight.

- Signal interference (buildings, Wi-Fi, towers).

Choose open areas; keep antennas facing the drone.

- Phone performance / background apps.

Close other apps; ensure your phone meets app requirements.

- Abrupt stick inputs.

Use smooth stick motions to keep the link stable.

- Battery not seated in hub or aircraft.

Insert until it clicks and LEDs behave normally.

- Damaged charger/cable or wrong adapter.

Use the original Type-C cable and 5V/3A adapter.

- Temperature out of range.

Charge at 5–40 °C (41–104 °F). Full charge ≈ 3 h per flight battery.

- Power on drone (level surface), then TX (short press + hold 3 s).

Wait ~40 s; TX long-beeps when paired.

- Connect phone to TX via the included cable.

On Android, choose “Charge only” if prompted. Open HS FLY app to view live feed.

- Supports Class 10 (or above) TF cards up to 256 GB.

Insert the card before powering on for up to 4K photo (4000×3000) and 4K@20fps video to card.

- Phone recording is lower resolution.

4K to TF card; up to 1280×720@30fps to phone.

- Smart RTH (manual).

Short-press the RTH key; the drone returns to the recorded Home Point at the set Return Altitude (RA).

- Failsafe RTH (auto).

Triggers on signal loss (with GPS & Home Point). Control is restored if link reconnects; press RTH to exit.

- Low-Voltage RTH (auto).

Stage 1: return & hover in a safety zone (≈98 ft radius/66 ft height). Stage 2: auto-land when critically low.

Obstacle avoidance is not available during RTH — fly in open areas.

- Default caps for new users.

Distance ≤ 98 ft (30 m), Altitude ≤ 98 ft (30 m), RTH Altitude 66 ft (20 m).

- Need custom limits?

Turn off Beginner Mode in HS FLY > Settings, then set distance/altitude/RA as needed.

- Yes, in ATTI with Optical Flow.

Long-press GPS key to enter ATTI. Optical-flow works best at 1.6–9.8 ft; avoid dark/reflective/textureless floors.

Precision is affected by lighting and surface texture—proceed carefully.

- For emergencies near the ground.

Hold the Emergency key for 2 s below 16 ft altitude to cut motors. Use only to avoid danger.

- Speed modes.

Camera 3 m/s (Low), Normal 5 m/s (Mid), Sport 7 m/s (High). Short-press Speed to switch.

- Gimbal tilt.

Dial to adjust −90° to 0°.

- Use outdoors, strong GPS, clear surroundings.

Respect minimum distances (e.g., ≥7 ft from subject for Catapult/Ascension; ≈16 ft for Spiral Up) and note follow limit ≤164 ft.

- No obstacle avoidance.

Monitor the path and be ready to exit via the right stick or tapping the mode icon.

- For TapFly.

Pre-load the map on Wi-Fi/Cellular, then plot ≤16 points and tap GO.

- Flight battery: about 3 h to full; up to ~40 min per battery (no wind).

Use 5V/3A adapter and the original cable via the charging hub.

- Transmitter: about 110 min to full; ~2.5 h usage.

You cannot power on the transmitter while charging.
