Reedy's RC4020A HV Digital Competition Crawler Servo is trail-tested and engineered for use in competition-level trail trucks, crawlers, and monster trucks. A powerful motor creates incredible torque without sacrificing speed, while an advanced microprocessor provides precision steering control.

An all-metal gear set is designed for strength and durability while a CNC-machined full-aluminum case reduces operating temperatures for fade-free operation. Because the RC4020A features HV 8.4V compatibility, external BEC units can be utilized to create an incredible 50 kg-cm (695 in-oz) of torque.
