Holy Stone HS720E wind limit
Holy Stone’s rated wind resistance, recommended limits in every unit, and what a ground forecast means at 120 m.
Holy Stone doesn’t publish a wind resistance figure for the HS720E. Altiwind then uses a cautious 7.9 m/s (Level 4, 18 mph) as its limit, so 20 mph (8.9 m/s) of steady wind at flight height would already be Outside your limits.
Cold weather
Holy Stone rates the HS720E 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 HS720E, 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.
