Power HD WB-150KG HV Brushless Digital Servo, 150 kg·cm at 25.2 V

The Power HD WB-150KG is a high-voltage brushless digital servo, the flagship model of the Power HD WB series, specifically designed for 1/5 and 1/6 scale RC models such as monster trucks, buggies, and crawlers. It features a massive aluminum heat-sink case, heavy-duty steel gears with a 15T large spline output, and an efficient brushless motor. Operating within a voltage range of 16.8 V to 25.2 V DC, this 213 g servo delivers an impressive torque of up to 150.0 kg-cm and a speed down to 0.09 s at 25.2 V. Designed for demanding applications, the servo operates at temperatures from -10 °C to 60 °C with an operating frequency of 1520 µs / 333 Hz and measures 59.5 × 29.5 × 54.4 mm.
