HS320 Real Shots

- Power on the drone, then power on the remote.
               → Push the left stick up then down to bind. LEDs turn solid when paired.

- If pairing fails, move to an open area and reboot both devices.
               → Keep the drone on a level surface during start-up.

- Use One-Key Takeoff/Landing (long press the button).
               → The drone will auto take off and hold altitude; long press again to land.

- For emergencies, long-press both top buttons to stop the motors.
               → Only use Emergency Stop in a real emergency.

- Minor drift is normal indoors or in airflow; use the Trim button to fine-tune.
               → After bumps, perform a gyro calibration (both sticks down-right) on a flat surface.

- Propellers may be bent or mismatched (A/B).
               → Replace damaged props and match A/B markings correctly.

- Three speeds: Low / Mid / High. Short-press Speed to switch (1/2/3 beeps).
               → Start in Low; increase as skills grow.

- Headless Mode (long-press): stick forward = fly forward regardless of the nose direction.
               → Turn off when practicing orientation flying.

- Short-press the Bubble button to turn bubbles on/off.
               → Long-press to switch bubble level (Low/High).

- If bubbles are weak, refill the tank or use the recommended mix ratio (2 packs + water).
               → Avoid over-diluting the solution.

- Tank is empty or not locked in place.
               → Refill and reinstall until it clicks firmly.

- Nozzle blocked by debris or dried liquid.
               → Power off, wipe the nozzle, and keep the tank clean.

- Battery is low; bubble motor may slow down.
               → Replace/charge the battery and try again.

- Yes. Although the drone auto-stops bubbles after landing, it’s recommended to manually turn bubbles off before touchdown.
               → This helps prevent nozzle damage from dust or fibers on the ground.

- Up to 18 min per battery (no tank), about 15–16 min with the bubble tank installed (low level).
               → Bubble output per tank (low level) is about ≈6 min; times vary by conditions.

- Remove the battery and use the included USB cable with a 5V/2A charger.
               → Let the battery cool to room temperature before charging.

- Indicator on = charging; off = fully charged.
               → Never leave charging unattended.

- The aircraft LEDs flash and the remote beeps.
               → Land promptly and replace/charge the battery.

- Open outdoor areas with little wind and no obstacles (people, trees, power lines).
               → Avoid sand/grass on landing to keep the bubble gears clean.

- Install prop guards for beginners and indoor practice.
               → Always supervise children during operation.

- After play, empty the tank and wipe the nozzle dry.
               → Store the tank separately to prevent residue buildup.

- If not used for a while, rinse the tank with clean water and dry before the next use.
