Brushless Motor FlashHobby A4214 350KV

The FlashHobby A4214 350KV is a high-torque brushless motor designed for large multirotor drones, heavy-lift UAVs, and industrial applications. With its low KV rating and wide stator size, it provides stable performance with large-diameter propellers, ensuring efficiency and endurance during extended missions.

Built with high-quality bearings and a precision-machined aluminum housing, the motor offers reduced vibration, smooth operation, and excellent durability. An optimized cooling structure prevents overheating under continuous heavy loads, making it suitable for demanding use cases.

Supporting 15–17 inch propellers and running efficiently on 6–12S LiPo batteries, the A4214 350KV is capable of producing up to 3.5 kg of thrust, making it a solid choice for cargo drones, mapping platforms, and endurance-focused UAV builds.

This motor is an excellent choice for builders and engineers who prioritize reliability, efficiency, and high torque in their large-scale drone projects.
