Product overview
The T-MOTOR X-A12XL-14S is a propulsion arm set for coaxial multirotor drones. It combines an X-A12XL KV77 brushless motor with a 14S 200A FOC electronic speed controller in a modular assembly. Its propulsion components are pre-matched to simplify installation and integration, and the specified tube size is 50 mm. The two arm-set configurations are X-A12XL KV77+14S FOC 200A and X-A12XL KV77+14S FOC 200A+PFZ4918P. A 49-inch carbon fiber folding propeller is optional.
The system is intended for 100–120kg coaxial multirotor drones. Its configuration-specific recommended take-off weights are 120kg for quadcopters and 180kg for hexacopters. Rated thrust is 30-35kg, with a 12-14S LiPo battery recommended as the power source. For aircraft integration, the arm set combines these electrical requirements with the 50 mm tube specification and optional folding propeller. The propulsion system has IPX6 ingress protection, and its recommended operating temperature extends from -20°C to 55°C.
