Brushless Motor Surpasshobby S4214 660KV

The SurpassHobby S4214 660 KV motor is tailored for X-Class and long-range drones equipped with large 13–14" props. Its 14-pole design enables smooth startup, precise throttle control, and minimal vibration under load.

A robust stator measuring 42 mm in diameter by 14 mm high, combined with a dense winding layout, delivers substantial thrust while maintaining thermal efficiency. The housing includes vents for improved cooling, and an M6 lock nut secures the shaft for high-load reliability.

Operating across a voltage range of 22–42 V (6–10 S LiPo), the motor handles up to 1665 W of power and peaks at 79 A, producing impressive performance metrics.

Weighing ~260 g and sized at Ø 50.4 × 60.5 mm, it stands out as a powerful, reliable choice for heavy-duty and long-duration drone builds.
