The RCD 3115 900KV brushless motor is engineered for professional-grade multirotors and FPV cinelifter platforms. Featuring a 31mm stator diameter and 15mm height, this motor delivers reliable thrust and torque for heavy-lift applications. It is ideal for 3–6S LiPo power systems, supporting high-end aerial cinematography rigs like the Taurus X8 Pro, Protek60, or X-Class FPV drones.
Designed with 12N14P stator configuration, precision-balanced rotor, and M5 threaded shaft, the RCD3115 provides exceptional torque stability and high efficiency under full throttle loads, ensuring stable, vibration-free footage for demanding FPV or industrial payloads.
