SRT BH125W 1/5th HV Brushless Servo

The SRT BH125W 1/5th HV Brushless Servo delivers serious holding power and rapid response for large-scale RC use. Combining a brushless motor, metal gears and NMB dual main bearings, this digital servo is engineered for efficiency, low power consumption and durability in demanding conditions.

Operating on 6.0–8.4 V, the BH125W produces up to 125.0 kg.cm of stall torque with transit times as quick as 0.085 s/60° at 8.4 V. Control is precise via pulse width control at 1520 μs / 330 Hz, while a 15T output shaft provides robust interface with compatible servo horns.

With dimensions of 59.5 x 29.5 x 54.5 mm and a 209 g weight, installation is straightforward, and the 350 mm JR lead offers ample routing length. The waterproof construction adds confidence when conditions turn wet or dusty.
