Model: ST-350
The ST-300 is a UAV designed for stable and efficient operation across a wide range of altitudes and flight conditions. It operates most effectively between 400 and 2,000 meters, with a minimum allowable altitude of 60 meters, and can reach up to 5,000 meters using its internal combustion engine or 6,000 meters with its electric motor.
In terms of performance, the ST-300 delivers a maximum speed of 25 m/s, with a cruise speed of 18–20 m/s for optimal efficiency. It maintains controlled flight at lower speeds down to 18 m/s, with a stall speed ranging between 14 and 16 m/s, ensuring reliable handling and operational stability.
