Standard Size Servo For 550-700 Class Helicopter Tail
The KST BLS805X HV Tail Servo is engineered for high-speed, high-precision performance, making it an ideal choice for 3D helicopter pilots flying models in the 550 to 700 class. Built around a high-voltage brushless motor, it delivers lightning-fast response with a pulse speed of just 0.039 sec/60° at 8.4V, giving you sharp, confident tail authority even in the most aggressive maneuvers.
Housed in a robust CNC-machined aluminium case, and equipped with durable steel gears and dual ball bearings, the BLS805X is designed for long-term reliability and resistance to heat and vibration. It runs on 760μs / 560Hz, so be sure your gyro system supports this narrow-pulse, high-frequency specification.
