Hitec have introduced the new D956WP high-torque, waterproof servo. Based off the D954SW servo, the IP-67 rated version is the true waterproof, dust resistant upgrade for 1/10th-scale Rock Crawlers and Trucks. As with the entire “D” line, this technologically-advanced servo is powered by Hitec’s 32-bit MCU (Microcontroller Unit) and 12-bit ADC (Analog to Digital Converter) industrial science and possesses Smart Sense engineering with rapid, high-resolution response. The unprecedented programmability and wide-voltage capabilities deliver the most progressive, leading-edge performance for all radio control needs. With incredibly durable steel gears, dual ball bearing and hardened steel output shaft, the high-end performing D956WP produces the mighty torque and reliability required to take bashers to the next level.
