Power HD B8RS 30kg 0.075s Brushless Servo (HD-B8-RS)

Developed with pro drivers, the Power HD B8RS (HD-B8-RS) is a 55 g brushless servo designed for 1/10 on-road and electric-buggy racing. Engineered for ultra-lightweight setups with low current draw, massive torque and razor-sharp response, it delivers 30 kg·cm torque and 0.075 s transit speed at 8.4 V. A brushless motor, dual ball bearings and a robust 7075 aluminium/steel geartrain provide smooth, durable performance.
