Product overview
The S-300 is a heavy-lift multirotor flight platform intended for mountain engineering and transport. Its four-axis, eight-propeller architecture measures 205 × 195 × 90 cm unfolded and 150 × 135 × 90 cm stowed, establishing its deployment and transport footprint. Aircraft weight excluding batteries is 105 kg, standard payload is 250 kg, and maximum takeoff weight is 535 kg. Maximum payload carries conflicting ratings of 300 kg and 350 kg. A weighing system is included as standard equipment.
The power configuration uses four batteries with an energy capacity of ≥14 kWh. Endurance is 25 minutes unloaded and 8 minutes with the standard 250 kg payload. Charging takes 15 minutes per set using four fast chargers at ambient temperatures from -10°C to 45°C. Communication distance is 30 km with line of sight and no interference. The flight ceiling is ≤3000 m. With high-altitude propellers, maximum operating altitude has conflicting limits of ≥4500 m and ≤4500 m. Operating temperature spans -20°C to 55°C.
