DS Servo 20KG 3218 Pro

The DS3218 Pro Servo Meet the arena-proven standard servo builders actually like to use. DS3218 Pro Servo (180°) delivers confident control for lifters, clamps, and steering thanks to its metal gear train, dual ball bearings, and heat-shedding aluminum mid-case. It centers cleanly, holds position under load, and keeps moving after the hits. You get true 180° travel for smooth linkage geometry, plus a 25T (Futaba-style) spline for easy horn swaps and upgrades. The standard-size footprint drops into common mounts, and setup is straightforward—standard PWM control, quick response, and predictable feel on the sticks. Builder tips: set transmitter endpoints so the arm never “hard stops,” keep linkages free of bind, and design for headroom so the servo isn’t living at stall. Do that, and this workhorse will give you the repeatable motion your mechanism deserves.
