High power 700 W. high performance for mid-sized hexacopters and octocopters with the right propeller selection.
Configuration 12N14P. Optimal combination of coils and magnets for smooth running, high torque and good efficiency.
Compact sizes. With a diameter of 42 mm and a height of 36 mm, it easily integrates into the frames of most high-power drones.
Durable aluminum housing. Reliable protection from external influences while maintaining the lightness of the structure.
high torque. Confident rotation of large propellers, providing stable flight and high lifting force.
QX-Motor 4208 380KV is a brushless motor with an external rotor (Outrunner). It is the outer part of the housing with magnets that rotates. This design creates high torque for efficient rotation of large screws. The key parameter is KV 380 (rpm per volt). This value is ultra-low, ideal for powering high voltage LiPo 6S batteries.
The motor does not strive for a huge rotation speed, but generates maximum torque. It is used in conjunction with large propellers (eg 15x5.5) to lift heavy payloads on professional platforms.
The QX-Motor 4208 380KV is ideal for professional hexacopters, octocopters and VTOL vehicles carrying heavy payloads - from agricultural sprayers to survey systems and cargo platforms. It is also used in large aircraft and VTOL, electric and hybrid drives.
