Power HD WH Series servos

Power HD have introduced their new WH line of high voltage and high torque servos specific to the crawler segment. Coming in 3 different versions, 40kg/cm, 30kg/cm & 20kg/cm, all feature a CNC machined blue anodised aluminium case with waterproof ring inside, and customised waterproof wiring with special glue injection to secure the cables. Internally they use hardened steel gears to reduce gear chipping during intense driving, and a 32-bit MCU high-frequency processor makes the servo operation more precise, offer noiseless operation, locked-rotor protection and power-on slow-start protection.
