TopServo B2606 B4008 32kg 47kg 8.4V Brushless Waterproof Servo High-Speed High-Torque Stainless Steel Gear 25T for 1/10 1/8 RC Car

Overview

The TopServo B Series B2606 and B4008 are high-performance brushless digital servos designed for 1/10 and 1/8 scale RC cars, trucks and other demanding RC applications.

Both models feature a brushless motor, stainless steel gears, 25T output spline, IP68 waterproof construction and 4.8–8.4V wide-voltage operation.

The B2606 is optimized for speed, delivering up to 32 kgf·cm torque at 8.4V with a fast 0.055 sec/60° operating speed.

The B4008 is designed for higher torque applications, producing up to 47 kgf·cm at 8.4V while maintaining a fast 0.075 sec/60° response.

This makes the series suitable for users who need either faster steering response or stronger steering torque in performance RC vehicles.
