Product overview
The Ascend Kunpeng S11L integrated propulsion system combines an S11L motor, a 14SFOC180A electronic speed controller and a TS43 propeller in one kit. Designed for use with a 14S lithium-polymer battery, it provides a maximum thrust of 38 kg and a recommended takeoff weight of 18 kg per axis. Efficiency at that recommended weight is 6.2 g/W. The assembly accommodates a carbon tube with a 50 mm outside diameter and weighs 2230 g ±2%, including cables and propeller.
The 90 KV motor measures Φ122 × 52.2 mm. Electrical connections use red and black 10 AWG power cables and a 5P Teflon signal cable measuring 1700 ±5 mm. The ESC supports PWM/CAN control, a fixed 1050–1950 μs throttle range and a maximum voltage of 60 V. Its continuous and peak current limits are 50 A and 140 A respectively in an open environment at temperatures ≤60°C. The system operates from −20°C to 55°C and carries an IP36 protection rating.
