The D956WP has arrived! Based off the D954SW servo, this IP-67 rated version is the true waterproof, dust resistant upgrade for 1/10th-scale Rock Crawlers and Off-Road Trucks. As with the entire "D" line, this technologically-advanced servo is powered by a 32-bit MCU (Microcontroller Unit) and 12-bit ADC (Analog to Digital Converter) with Smart Sense engineering and rapid, high resolution response. The unprecedented programmability and wide-voltage capabilities deliver leading-edge performance for all your radio control needs. With incredibly durable steel gears, dual ball bearing and hardened steel output shaft, the D956WP produces the torque and reliability required to take bashers to the next level.

Servos are powered by the ESC's output to the receiver. If you're using a higher-strength servo than the ESC can support (usually greater than 20kg), you may experience 'brown-outs' where the radio signal can be interrupted and cause erratic driving. This can be helped by plugging a Glitch Buster into the receiver to smooth the current delivery. However, in some cases, you may need to install an external BEC.
