CS-20DS Standard Size Servo, RC servo, waterproof

The CS-20DS standard size servo brings fast actuation and high control force to RC models that need a serious steering or throttle component. With a voltage range of 6 to 8.4 V, 25 kg/cm torque at 8.4 V and a transit speed of 0.10 sec per 60°, it suits builds where quick response and firm holding power matter on the track or over rough ground. Its internal layout combines a core motor with a metal gear train and 2 ball bearings, a setup aimed at accurate movement under repeated load. The housing measures 40.5 x 20.2 x 38 mm and weighs 62 g, making the servo a regular-size format that fits many common RC installations without oversized packaging around the mechanism. The 25-tooth output gearing provides a defined interface for linkage setup, and the included servo horn set supports installation work straight into the model. Waterproof construction expands the range of running conditions to wet surfaces and rainy sessions where exposed electronics need added protection. In off-road chassis, touring cars and upgrade projects, the CS-20DS can take on steering duties where fast centring and strong torque shape the handling feel. It also suits kit-based model builds that call for a standard size servo with JR connection and clearly stated electrical and mechanical data.
