Brushless Motor Surpasshobby B4218 330KV

The SurpassHobby B4218 330 KV is built for demanding FPV builds—perfect for large X-Class frames where massive lift and long-duration performance are essential. Its low KV combined with a large 42 × 18 mm stator enables the motor to spin very large props effortlessly, delivering confident lift even with heavy setups.

Internally, its 0.2 mm silicon laminations reduce energy loss and heat, while the 14-pole rotor, dynamically balanced, ensures smooth operation and minimal vibration—crucial for camera work and precision flight.

On 6–11 S LiPo, this motor delivers an impressive ≈ 8200 g of thrust (in the 330 KV version), handling up to ≈ 2900 W of power and 75–80 A of current — ideal for aggressive, high-end aerial performance.

Mounting is streamlined with a 6 mm shaft and 30×30 mm bolt pattern (4× M4)—making it easy to integrate into large drone frames. An M6 lock nut ensures secure attachment under heavy loads.
