Weather conditions categorized by safety level
Clear skies, wind under 6 m/s, temperature 5-35°C, no precipitation
Light clouds, wind 6-12 m/s, temperature -10 to 40°C, no rain
Strong wind over 12 m/s, rain, fog, temperature below -10°C or above 40°C
Understanding weather impact on flight performance
The Evo II Dual 640T can handle winds up to 12 m/s, but strong gusts can affect stability and battery consumption. Always monitor wind conditions before and during flight, and use the return-to-home function if conditions worsen.
The Evo II Dual 640T is not waterproof and should never be flown in rain or wet conditions. Water can damage the electronics, motors, and camera, voiding your warranty. Always check weather forecasts and avoid flying if precipitation is expected.
Extreme temperatures can significantly impact battery performance and flight time. In cold weather (below 0°C), batteries discharge faster and may not provide full capacity. In hot weather (above 35°C), the drone may overheat. Always keep batteries at optimal temperature before flight and monitor battery levels closely in extreme conditions.

Common questions about weather limits and flight conditions
The Evo II Dual 640T can safely fly in winds up to 12 m/s. However, we recommend flying in winds under 6 m/s for optimal stability and video quality.
No, the Evo II Dual 640T is not waterproof and should not be flown in rain or wet conditions. Water damage will void the warranty.
The drone can operate in temperatures from -10°C to 40°C. Extreme temperatures can affect battery performance and flight stability.
The Evo II Dual 640T has a flight time of approximately 40 minutes under ideal conditions. Wind, temperature, and flight patterns can reduce this time.
The Evo II Dual 640T can reach speeds up to 20 m/s. However, higher speeds consume more battery and reduce flight time.
If you encounter winds stronger than 12 m/s, immediately return the drone to home position. Use the return-to-home function if available, and land as soon as safely possible.
The drone can operate in temperatures down to -10°C. In cold weather, battery life may be reduced, so keep batteries warm before flight.
The Evo II Dual 640T weighs 1150 grams. This weight affects flight stability, battery consumption, and portability.
