Brushless Motor Surpasshobby B4214 400KV

The SurpassHobby B4214 400 KV is a brute-force motor engineered for X-Class and heavy-lift FPV platforms. Featuring a 14-pole rotor, it delivers exceptionally smooth torque and powerful low-end performance, minimizing vibration—perfect for payload-heavy drones.

The precision-machined aluminum housing includes strategic ventilation for enhanced cooling. Internally, a full-size stator and high-grade magnets offer consistent operation even during intense, prolonged flights.

On 6–11 S LiPo, this motor can generate up to ~7314 g of thrust, making it stand out in the high-power FPV category. It handles peak power ratings near 2478 W and peak currents around 79 A, delivering performance that impresses even seasoned pilots. The weight is ~260 g, offering an excellent power-to-weight ratio.

Installation is seamless with a 6 mm shaft and a 30×30 mm mounting pattern (M4 screws)—ideal for integrating into industrial X-Class frames. An M6 lock nut ensures secure attachment even under extreme load.
