XNOVA LIGHTNING 4025-670KV SERIES (SHAFT A) - KRAKEN/RAW 580 (8S SETUP)

The Xnova Lightning 4025-670KV 2.5Y Brushless Motor (Shaft A) is a high-performance motor designed for demanding 520-600 class RC helicopters. Built with premium materials and precision manufacturing, the Lightning series delivers exceptional power, efficiency, and smooth throttle response for both sport flying and aggressive 3D performance.

Xnova’s Lightning motors feature high-grade neodymium magnets, thin stator laminations, and a precision balanced rotor assembly to maximize efficiency and reduce operating temperatures. The optimized internal design provides extremely smooth power delivery while minimizing cogging torque, giving pilots excellent throttle control throughout the entire flight.

The 4025-670KV motor is typically used with 6S–8S LiPo setups on 550–600 class helicopters, providing excellent efficiency and strong torque for sport and 3D flying. For pilots seeking extreme performance, this motor can also be used with 8S–10S LiPo setups for extreme 3D applications when paired with appropriate gearing and ESC configuration.

The Shaft A configuration (36mm) comes with the factory installed shaft commonly used in many modern helicopter frames, making it compatible with a wide range of popular helicopter models.
