Holy Stone HS600 wind limit

Holy Stone rates the HS600 for winds up to 7.9 m/s (18 mph, 28 km/h, Level 4). A steady 15 mph (6.7 m/s) at flight height is 85% of that rating, which our score calls Marginal. For a comfortable margin keep sustained wind at altitude under 4.7 m/s (11 mph) and estimated gusts under 6.3 m/s (14 mph).

Wind limits in every unit

Our default go/no-go thresholds are a share of the maker’s rating: sustained wind up to 60% is within your limits, up to 85% is marginal; estimated gusts up to 80% are within, up to 100% marginal.

What a ground forecast means at 120 m

Most forecasts give wind at 10 m. Higher up it is stronger. With the standard power law (α = 0.14 over open land by day, about 0.25 at night or over towns and forest), here is the sustained wind the HS600 meets at 120 m (400 ft), and how our score rates it. Altiwind uses the model’s own 80, 120 and 180 m winds where they exist.

Sustained wind only. Gusts come on top: Altiwind adds the forecast 10 m gust excess (gust minus mean, never less than 20% of the wind), so check the estimated gusts too. See wind at altitude and gust forecast. UAV Forecast also shows wind by height: how it compares with Altiwind.

Cold weather

Holy Stone rates the HS600 down to 0 °C. Batteries lose capacity in the cold well before that, so Altiwind marks every hour below 5 °C as marginal with a battery warning, and below 0 °C as outside your limits. A 0 °C lower limit is common for this class: below freezing, keep flights short and batteries warm until takeoff. More in flying drones in cold weather.

Rain and moisture

There is no water rating stated for the HS600, so Altiwind treats rain as a limit: a rain chance of 20% or more is marginal and 50% or more is outside your limits. Fog and low cloud also cut visibility, which the score checks separately. See fog, rain and humidity.

Not confirmed on the maker’s page: release year, flight time.

2-axis gimbal. Maker page states both "Level 6" and 7.9 m/s (7.9 m/s is the top of Beaufort 4) - inconsistent. No flight time on maker page; 28 min from retailer listings citing a 2500 mAh battery, while the maker page now lists 3500 mAh. Release year not found. Holy Stone states both "Level 6" and 7.9 m/s; we use the lower 7.9 m/s.
